Strickland — The Noctuid Genus Copablepharon 



83 



stage. This larva was found below ground, among other cutworms, 

 and in captivity it fed freely on alfalfa and to some extent on 

 barley. 



When mature the larva measured 1| inches in length, and by 

 July 5 it had pupated in an earthen cell similar in construction 

 and size to that of the species of Euxoa, though it was somewhat 

 distorted internally. 



Thus it will be seen that Copablepharon larva? are typically 

 Agrotine in their habits, and were it not for the minute tubercle II 

 their structure also would be in harmony with that of typical mem- 

 bers of this sub-family.

 nal segment IV of Chorizagrotis thunatolngiu Dyar. 



The pupa, of which an illustration is given, is remarkable in 

 that the proboscis sheath is so elongated that it extends beyond 

 the apex of the abdomen. The pupa itself is 1!) mm. long and the 

 proboscis sheath, of which 8 mm. is free, extends ^ mm. beyond 

 the cremaster. 



The only other Noctuid pupse which we know to have an ex- 

 tended proboscis sheath are those of certain genera of the Cucul- 

 liinse, and to a less extent the Plusiinae.
