LEPIDOPTERA. 

 By HARRISON G. DYAR. 



Ctnucha venosa Walker. 



One example. The species flies in Mexico, Texas and Col 

 orado, and has been taken in the canyons of the Rocky Mountains. 

 It is not uncommon, yet was not taken by us on this trip, except 

 this example on the snow. 

 Gnophala latipennis Boisduval. 



One example. The species was flying at the Half-Way House 

 and had been abundant there a week previously. It was seen 

 also in several of the canyons. 

 Carneades perexcellens Grote. 



One example in poor condition, rendering the identification 

 uncertain. The moth is a common Noctuid of the foot-hills. 

 Clisiocampa fragilis Stretch . 



Fifty examples. The species was occuring in countless num 

 bers above the Half- Way House, where acres of aspen trees had 

 been defoliated by the larvse. The moths were flying in swarms 

 all day about the leafless trees, which were loaded with their 

 cocoons like fruit.
