LARV^ OF MOTHS FROM COLORADO— DYAR. 873 



white, pinkish shaded in the incisures. Warts black, hair bristlj^, 

 sparse!}' barbiiled; 1 small, less than one-third the size of ii, i with 

 small, ii with large shining base, normal. Hair all black, even the sub- 

 ventral, longer on joints 12 and 13. 



One larva found by Mr. E. J. Oslar on the foothills, Ma}' 12; it fed 

 on alfalfa. The moth that emerged was of the form f-jMllida 

 Strecker. 



LEPTARCTIA CALIFORNIA Walker. 



7i(/(/. — Low conoidal, practically two-thirds spherical, shining pearly 

 flesh color; rather coarsely reticularly shagreened, almost definitely 

 reticuhite at the vertex, but the lines broad and confused; diameter 1 

 mm., height 0.7 mm. 



SfH{/f' L — Head bilobed, erect, shining black. Body translucent, 

 faintly yellowish, warts and shields dark brown, thoracic feet black; 

 slight reddish-brown shading about the warts. On thorax warts ia and 

 ib united on a single large plate, single haired; iib small, shortly sepa- 

 rated from iia; iv single, vi double, no subprimaries. On alxlomen i 

 small, ii on a large plate, iii with two hairs, iv and v single, iv well 

 behind the spiracle, vi absent, but a small, elongate, hairless shield in 

 its place; vii forming a well-developed shield on the leg. Cervical 

 shield with four hairs on each side, three of them black; two other 

 hairs detached on a tiny wart. Joint 13 anteriorly has one wart with 

 four hairs and one with two. The rudimentary tuliercle vi is present 

 on joints 5 to 12. Hairs long and tine. 



The remaining stages have been full}' described by Prof. G. H. 

 French.' He found iive stages, which my observations do not con- 

 tradict. Mr. Oslar secured me some eggs, and I obtained others from 

 moths taken on the foothills behind Golden, and later I found some 

 larvai there on the ground or feeding on low plants. The species is 

 not uncommon in the foothills and canyons; I remember it to have been 

 abundant in Williams Canyon near Manitou in 1801. 



LEUCARCTIA ACRAEA Drury. 



This ul)iquitous larva occurred on the prairie and on the footh'lls as 

 high as Salida, where Mi's. A. N. Caudell collected one. The spcc'cs 

 seems to despise all natural boundaries and l)e at home in all faur'' 

 regions. 



EUBAPHE AURANTIACA Huebner. 



E<jgs. — Rather low, roundedly conoidal, the base fiat and slightly 

 rimmed; shining pale yellow. Reticulations narrowly linear, irregu- 

 larly hexagonal, not raised, faint. Diameter, 0.6 mm. Turned dull 

 pink. 



Stage I. — Head rounded, cordate, pale luteous, shining, broadly
