have never seen any on San Pedro, but several times thought that I heard their call notes.

Phainopepla nitens. PHAINOPEPLA. Very common at certain times about the base of the mountain up to about 6000 feet.

Vireo solitarius cassinii. CASSIN'S VIREO. Not uncommon in the pines where it was first seen May 13; it became more common a week or so later.

Vireo bellii pusillus. LEAST VIREO. Very common all along the base of the mountain, but probably not reaching above the live oaks at 4500 feet.

Helminthophila celata lutescens. LUTESCENT WARBLER. Seen along the western base of the mountain and in all the lower valleys during the spring migration.

Dendroica astiva. YELLOW WARBLER. Common during migrations in the valleys and as a summer resident in the higher altitudes. A single skin in my collection from La Grulla, No. 4031, May 15, is the brightest colored specimen I have ever seen from any locality, and also differs from others in my series in having a well defined dark shaft streak along the inner web of the tail feathers, occupying half of the web which is yellow to the shaft in all æstiva that I have examined. Unfortunately the specimen is the only one I have from that region, and I am unable to say how constant the character may prove to be.

Dendroica auduboni. AUDUBON'S WARBLER. Very abun dant during migrations; one taken at La Grulla, May 13.

Dendroica nigrescens. BLACK-THROATED GRAY WARBLER. Rather common as a summer resident in the pine belt, nesting in the Manzanita thickets.

Dendroica townsendi. TOWNSEND'S WARBLER. During the past spring this warbler was first met with in the Burro Cafion, where a dozen or more were seen in the live oaks, April 23. As they were quite restless and somewhat difficult to identify, it is not improbable that occidentalis also occurred at this same place. They were again met with at Valladares, May 3, and on the following day on the west side of San Pedro at each of these localities they were quite common in the live oaks with D. nigrescens and occidentalis.

Dendroica occidentalis. HERMIT WARBLER. Quite common at Valladares and on San Pedro at 4500 feet; several were taken at each camp.

Geothlypis trichas occidentalis. WESTERN YELLOW-THROAT. A female was taken at La Grulla, May 1, 1889; not uncommon about the base of the range.

Icteria virens longicauda. LONG-TAILED CHAT. Common in the lower valleys, but only seen occasionally along the base of the mountain.

Sylvania pusilla pileolata. PILEATED WARBLER. Before we left the pine belt, this warbler had become common along the streams; more abundant, however, in the lower valleys during migrations.

Anthus pensilvanicus. AMERICAN PIPIT. A few seen in May, 1889, on the eastern edge of the mountain; abundant along the coast in winter.

Mimus polyglottos. MOCKINGBIRD. Probably does not extend above 5000 feet on the western slope of the mountain.

Harporhynchus redivivus. CALIFORNIA THRASHER. Not uncommon in the Manzanitas at 7000 feet, but rare above that point; a pair of Harporhynchus was seen in the shrub oaks at about 10,000 feet altitude that I thought was crissalis, but as they were not taken, the record is open to question.

Campylorhynchus affinis. ST. LUCAS CACTUS WREN. Common as far up the San Telmo Valley as suitable nesting ground. was seen, about thirty miles from the coast. Mr. Bryant recorded it from as far north as San Quintin, fifty miles south of San Telmo.

Salpinctes obsoletus. ROCK WREN. One found nesting at 8500 feet; more common on the lower slopes.

Catherpes mexicianus punctulatus. DOTTED CAÑON WREN. Not uncommon in several places on San Pedro.

Thryothorus bewickii spilurus. VIGORS'S WREN. Common along the western slopes of the mountain.

Troglodytes aedon aztecus. WESTERN HOUSE WREN. Abundant in the pines.

Sitta carolinensis aculeata SLENDER-BILLED NUTHATCH. Rather rare but well distributed in the pines.

Sitta pygmæa leuconucha. WHITE-NAPED NUTHATCH. The most abundant species on the mountain; found everywhere in the pines. Upon our arrival May 5 this species was mating; noisy little companies of five or six to a dozen were seen chasing one another through the pines, chattering and calling from daylight till dark; although dozens of nests were discovered all were practically inaccessible. A favorite location for the burrow was on the under side of a dead branch, well away from the trunk of a large pine, and from twenty-five to a hundred feet from the ground. A series of over one hundred and thirty skins sustain the characteristics of the types to a very gratifying degree.

Parus inornatus griseus. GRAY TITMOUSE. Seen in several localities on San Pedro but not at all common. Specimens from the base of the range were identified as griseus, but as I have no specimens from the pine belt I can only surmise its identity.

Parus gambeli. MOUNTAIN CHICKADEE. Abundant in the pines but found chiefly in the region of Manzanita and oak thickets. In winter it was seen about Valladares and along the lower valleys.

Chamaa fasciata henshawi. PALLID WREN-TIT. Common along the lower slopes of the mountain and not rare in the highest altitudes where it nests in the shrub oak and Manzanita.

Psaltriparus minimus californicus. CAIFORNIA BUSH-TIT. Not common in the pines, but noted from several localities; very abundant below 3000 feet.

Regulus calendula. RUBY-CROwned Kinglet. Rather common during migrations.

Turdus ustulatus. RUSSET-BACKED THRUSH. Seen in the pines as late as May 25; a female taken May 21; it is possibly a resident of the pines, but those taken showed little enlargement of the ovaries, and it is more probable that they were belated migrants.

Merula migratoria propinqua. WESTERN ROBIN. Common along the base of the mountain in winter; a few were seen in May, 1889, at La Grulla, but none were noted the past season.

Sialia mexicana. WESTERN BLUEBIRD. Very common during migrations from sea level to the top of the range, a few lingering to nest with the local race. A series of seventy-five skins taken the present year during the nesting season sustain the characters of anabela, as set forth by myself in 1889, to a strong degree, only about 5% of the males showing an unbroken band of bay on the breast, which refers them to true mexicana, and many of the high-plumaged males of the anabela stripe were almost entirely without bay markings on either breast or scapulæ.

LEUCARCTIA RICKSECKERI.

DR. H. H. BEHR.

Mr. L. E. Ricksecker sent me four specimens of a Leucarctia which he raised from larvæ found on a species of Senecio, and after careful comparison as to description and figure of L. albida, Stretch, I think that Mr. Ricksecker is justified to consider them a new species.

As Mr. Ricksecker lives in the country, rather isolated from scientific intercourse, he has empowered me to publish and name the species. I call it after its discoverer.

L. RICKSECKERI: grisea, alba. In utroque sexu palpi annulis duobus et apice atro signati. Antennæ atræ supra serie punctorum minimorum candidorum signatæ. Abdomen luteum, crines basales segmentumque apicale albi, series punctalis dorsalis atra. Alæ & ris anticæ grisea fasciis dilutis obscuris, posticæ sordide luteæ puncto discali et duobus submaginalibus dilutis. In utriusque sexus alis anticis ad bifurcationem venæ medianæ puncto atro bene distincto notatæ.

L. Rickseckeri is about the size of small specimens of L. Acraa. wings immaculate, except a minute black discal spot on anterior wing. Body similar to L. Acraa, but with the black spots fainter, sometimes obsolete. thorax and anterior wings a diffused smoky color, immaculate except the minute discal spot. Posterior wings yellowish-brown with one discal and two or three submarginal spots quite indistinct and nearly obsolete. Both pairs of wings are brown underneath with a few variable obsolete black points.

I have very little to add to this description of the insect by Mr. Ricksecker. It is true the description of L. albida by Stretch could be construed into a description of L. Rickseckeri 2. Mr. Stretch states that the specimen (a unicum) from which he described was in very bad condition, so that the discal point may have been wiped off in both anterior wings, and even the sex may have been mistaken, as the circumstance of the specimen being a unicum prevented dissection. No entomologist likes to destroy a unicum. But the characteristic of the palpi distinguishes the species at once and leaves no doubt as to its specific distinction. Coloration and markings of the distinguish the species from all American Leucarctias, and approach it to an East Indian species in our collection, which I received in several specimens from the coast of Arracan. This otherwise very distinct species has the same coloration as the 9.

In regard to its biology, I give here again the words of Mr. L. E. Ricksecker: "June 11, 1891, I found three larvæ about full-grown, similar in general appearance to those of L. Acræa on a species of Senecio. They commenced spinning cocoons June 18, and three males emerged July 18, 1891. June 18, 1893, I visited the same place, and after a long day's diligent search I had twelve caterpillars. June 15, they commenced spinning cocoons; June 20, eight cocoons (the remainder escaped from cage); July 5-12, six imagines- & 2, 94. Two cocoons contained parasites. Locality, Sonoma County." These are the notes of Mr. Ricksecker's journal.

CALIFORNIA EARTH-WORMS OF THE FAMILY OF

EUDRILIDE.

BY GUSTAV EISEN.

California, although a dry and rainless country for six months in the year, still possesses a varied oligochatological fauna rich both in species and individuals. The earth-wormsangle and rain-worms-burrow deep in the soil during the dry and warm months and lie there encysted and closely rolled up in clay chambers and waiting for the rain to set in in the autumn.
