“VOL. IV.] Leucarctia Rickseckert. 247 
Stalia mexicana,. WESTERN BLUEBIRD. Very common dur- 
ing 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 anabelz, as set forth by myself in 1889, toa 
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 azadele stripe were 
almost entirely without bay markings on either breast or scapule. 
LEUCARCTIA RICKSECKERI. 
DR. H. H. BEHR. 
Mr. L. E. Ricksecker sent me four specimens of a Leucarctia 
which he raised from larvee 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. Antenne atre supra serie 
punctorum minimorum candidorum signatze. Abdomen luteum, 
crines basales segmentumque apicale albi, series punctalis dor- 
salis atra. Alc 3 ris anticce griseze fasciis dilutis obscuris, pos- 
‘tieze sordide luteze puncto discaii et duobus submaginalibus 
dilutis. In utriusque sexus alis anticis ad bifurcationem venz 
medianze puncto atro bene distincto notate. : 
L. Rickseckeri is about the size of small specimens of L. Acrea. 
2 wings immaculate, except a minute black discal spot on 
anterior wing. Body similar to LZ. Acrea, 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.
