548 GEOLOGICAL SURVEY OF THE TEREITOEIES. 



rounding plateaus, while a study of the Japanese and Hindoo-Chinese 

 faunas must accomj)any examinations of the eastern or Atlautic faunas ; 

 just as we are daily obliged, while examining the Middle American 

 temperate fauna, to study West Indian and Central American and even 

 tropical South American forms, some of which spread as far north as the 

 headwaters of the Mississippi and even Maine and Canada. 



TORTKICID^. 



A larva of this family, with a flattened, pale, flesh-colored body, and 

 pale, testaceous head and prothorax, length, 0.40 inch, occurred at an 

 elevation of above 12,000 feet (Lieutenant Carpenter). 



PYEALID^. 



Cramhus Carpenterellus n. sp. (Fig. 1, wing enlarged), 5, <J; 3, ?; a 

 large species, allied in its style of markings to G. agitatellus, Clem., of 

 the Eastern States. Head, thorax, and palpi tawny ochreous; ab- 

 domen and hind wings white ; tore wings with a broad, prominent, 

 longitudinal, white streak, occupying the discal area, *. e., between the 

 subcostal and median veins, extending from the base of the wing rather 

 nearer the outer edge than in G. agitatellus. Just before the end of the 

 streak, a linear, minute branch is sent off from the costal side, and from 

 the middle of the lower side a short snag is sent off, with a dark streak 

 in continuation ; while along the opposite side is a dark streak. There 

 is no parallel white costal streak, as in G. agUaieUns. Below the white 

 streak, the wing is clearer yellow than elsewhere. The outer transverse, 

 angulated, silvery-white line is somewhat as in Cff agitatellus, but nearer 

 the edge of the wing, and bent angularly, and not incurved below the 

 bend. The line is bordered on each side by two oblique costal lines, 

 widening on the costa; apex brown, with a white triangle below; still 

 below a marginal row of about six distinct black dots; within the 

 transverse white line the usual parallel golden lines; fore wings 

 beneath dusky ; hind wings much paler. 



Length of body, 0.44 inch ; of fore wing, 0.55 inch. 



Mountains of Colorado, July 19, August 12, September 8 (Lieuten- 

 ant Carpenter). 



This fine species, named in honor of Lieut. W. L. Carpenter, U. S. A., 

 who has done much to add to our knowledge of the lepidopterous fauna 

 of Colorado Territory, particularly the more elevated portions, appears 

 to be a common species. It is allied in the general style of markings to 

 G. agitatellus, Clem., of the Eastern States, but differs from it in wanting 

 the costal white streak ; in the submarginal white line being bent angu- 

 larly, not sinuous below the bend ; and in being nearer the outer edge of 

 the wing. I have no Californian species with which to compare it. It is 

 still nearer allied to G. liamellus, of Europe. 



Cramhus, a species allied to G. mutahilis^ Clem., but not in a proper 

 condition for description, occurred at Fair Play, July 16 (Lieutenant 

 Carpenter). The same species apparently occurs in Oregon (Museum 

 Peabody Academy of Science, Salem, Mass.) 



Another, smaller species, dark slate-colored, with dark hind wings 

 occurred at Twin Lakes and on the mountains of Colorado, July 22 

 to August 12, (Lieutenant Carijenter). 



Nomophila noctuella, Schiff. — One specimen was taken at Fair Play, 

 July 16 (Lieutenant Carpenter), which does not differ from specimens 

 from Oregon and California and the Eastern States. The occurrence of 

 this species among the mountains of Colorado is additional evidence 

 that it is autocthonous in North America.
