SECOND NOTE ON A 

 LEUCA. 



NEW HEMI- 



Hemileuca soioria race oliviae, Ckll., 

 Psyche, 1S9S, p! 252. $. (Sta. Fe. N. M.) 

 On Aug. 20, 1S9S, Mr. John Davis sent me 

 some larvae collected at Maxwell Citv, N. M., 

 stating that they were then extremely numer- 

 ous, and were devouring the pastures. With 

 the larvae weie sent pieces of grass, which 

 Prof. E. O. Wooton identifies as a Miihlen- 

 bergia probably M. iesana Thurb. (poi-teri 

 Scrib.). From these larvae I bred four moths 

 of oliviae, which was only known heretofore 

 by a single^ ! A male emerged Sept. 13, two 

 males Sept. 14 and a female Sept. 15. 



Larva. Of the living larva, I noted as fol- 

 lows: — Ochreous with a very dark hrown 

 head ; body irregularly marbled with very dark 

 brown, especially about the sutures ; tufts of 

 spines as usual in the genus, the central ones 

 black, the lateral ones [spimtles] ochreous 

 with black tips; thoracic legs black. 



The skin is sparsely beset with colorless 



hairs. Spiracles narrowly edged with black. 



Cocoon. The cocoon is composed mainly 



of fragments of the Muhlcnbergia loosely 



woven, with many open spaces. 



Imago. The males agree in the main with 

 the Santa Fd type, but are perhaps, a little 

 grayer. The female expands 65 mm., and 

 has a warmer, more rosy color than the males. 

 The general color of the anterior wings is 

 nearly uniform, with the two pale bands dis- 

 tinct. 



Compared with the description of H. sor- 

 oria Hy. Edw., the ? oliviae differs thus:— 

 Costa of primaries orange-ferruginous 



throughout ; secondaries above with the nerv- 

 ures pale ferruginous ; on the under side the 

 nervures are pale ferruginous on all the 

 wings, and the costa of the primaries 

 is broadly orange ferruginous, subfuscous at 

 base, that of the secondaries washed with 

 blackish ; head clothed with dark fuscous 

 hair, gray on vertex and occiput ; thorax with 

 dense long gray hairs ; antennae entirely 

 bright orange ; abdomen above with fuscous 

 hair, chestnut on the first two segments; hind 

 margins of third to fifth segments with red 

 hair, which is replaced by white on the ex- 

 treme sides, and beneath except in the mid- 

 dle; apex with mixed fuscous, white and red 

 hair. The expanse is ii mm. less then that 

 of sororia. 



H. oliviae is of about the same size as //. 

 sororia hualapai (Neumoegen), from S. W. 

 Arizona, but differs in the markings. The 

 three forms, sororia, hualapai and oliviae 

 are clearly geographical races of a single 

 well marked species. 



In the Mesilla Valley, N. M., I liave never 

 taken //. oliviae, but only //. maia race ar- 

 temis (Pack) and //. /una Pack., the former 

 being much the most frequent.

A CURIOUS COCOON OF Att.\cus cecro- 

 Pi,\. _ In September last I found a very large 

 larva of Cecropia feeding on willow in a 

 swampy place. I took it home and it began 

 its cocoon the next day, in a white paper box, 

 from which I removed all leaves. The cocoon 

 was glistening white at first, and in this state 

 was packed with white cotton for transporta- 

 tion from Vermont to Brookline. The box 

 was unopened for a month, and when the 

 cocoon was taken out it was nearly all green, 

 the small spaces not green being just off 

 white. The pupa seems to be in good condi- 

 tion and is evidently alive.
