Teneina of Colorado. 297 



gined behind with white, and on the under surface the abdomen is 

 brown, and each segment is margined behind with white; legs brown, 

 the hinder pair annulate with ocherous. After being chloroformed 

 the specimen deposited a great many eggs, which are almost uniform, 

 and marked by five ridges which follow the outline of the shell, and 

 having a length of about -^-^1^, and heighth of about y^^ of an inch. 

 The food plants of the larvte of these species are not known. 

 Finding so many species in one locality, and knowing the partiality of 

 many species of the genus in the larval state for (Enothera and allied 

 plants, I searched these plants, which are very abundant at Spanish 

 Bar, carefully for the larvai, but without any other success than find- 

 ing in a very small mine, in a leaf of (Ebiennis, two young larvae, 

 which I believe to be those of Laverna, but which afterward died. 



Bedellia — B. somnulentella, St. 



I have not met Avith this species, but have found at Manitou 

 Springs (altitude, 6,100 feet), a few of its mines in leaves of Morning 

 Glory (Ipomea sp, ?). 



CosMOPTERYX — C. motitisella (n. sp.) 



Rich brown, but faintly tinged with green; second joint of the palpi 

 with three longitudinal white lines, one of which is on the under-side, 

 one on the outer and one on the inner surface ; third joint with a 

 white line beneath and one above ; basal joint of the antennae with a 

 white line above and one beneath, these lines also extend along the 

 stalk for more than half its length, the remainder of the stalk ^though 

 a little rubbed in the single specimen before me) appears to be annulate 

 with white, and with two large white annulations before the apex. 

 The head is marked with three white lines, one being over each eye, 

 and one on the vertex, the latter not extending down on the face; 

 tongue whitish ; thorax with four white lines, two of which are on 

 top and one on each side, the two middle ones also behig each continu- 

 ous with a white line which extends along the dor.-^al margin of the 

 forewing nearly to the fascia, and the two outer ones are each continu- 

 ous with a white line which extends along the costal maigin for a 

 short distance, and then leaving the margin, passes obliquely back- 

 ward to the fascia; (this is true only of one wing in this specimen, in 

 the other wing it does not reach the fascia, being much abbreviated, 

 and perhaps, in the wing, where it seems to reach the fascia, it is 

 more properly described as being also abbreviated and not reaching
