tion he states that the genus is related to Arsilonche in that the 

 eyes are lashless and naked, and to Ommatostola in the ornamenta- 

 tions and habits of the moth. It differs from either, however, in 

 the possession of spinose tibise. Both of these supposedly related 

 genera have been placed in the sub-family Acronyctinae by 

 Hampson ('16). 



Four species of moths were included in this genus when Smith 

 published his list of American Lepidoptera in 1903, and he placed 

 it next to the genus Nycterophseta, in the cuculliid group of the 

 undivided family "Noctuidse." This allocation of Copablepharon 

 was accepted, with slight modifications, by taxonomists until 

 Hampson ('03) transferred it to the sub-family Agrotinse on account 

 of its spined tibiae. Barnes and McDunnough ('17) follow Hamp- 

 son's classification in their check list, and this is the generally 

 accepted standard for American Lepidopterists. 



The six species now included in Copablepharon are apparently 

 confined in their distribution to Western America. They are 

 nowhere very common, and nothing has been published upon the 

 immature stages of any species. 



In the spring of 1913 larvae of C. longipennis Grt. and C. grandis 

 Strk. were taken in Manitoba and Alberta respectively. Mr. N. 

 Criddle, who found the longipennis larvae, and bred from them a 

 single adult, states that the larvae were typical "cutworms." 

 Unfortunately Mr. Criddle did not examine the pupal stage, which 

 was passed in an earthen cell below ground. 



On May 9 a single larva of C. grandis was taken in a stubble field 

 at Monarch, Alberta. 



This larva resembled superficially a lightly pigmented specimen 

 of Eiixoa ochrogaster Gn. (The Red-Backed Cutworm). Grandis, 

 however, differs from ochrogaster in that the median and lateral 

 lines are white instead of brown. In all of the larvae of Euxoa, 

 and of closely related genera, that we have examined tubercle II 

 is considerably larger than tubercle I (see diagram) . In the larva 

 of grandis, and also in specimens, now inflated, which Mr. Criddle 

 collected at the same time as, and believes to be identical with, 

 the specimen from which he bred longipennis this tubercle is no 

 larger than is tubercle I. 



The larva of grandis evidently hibernates when about half grown 

 since the specimen taken on May 9 in Alberta was in the fourth
