might decide is not given. In color and inaculation worthingtoni and 

 Jimbriaris agree wonderfully well, and both have lengthily pectinated 

 antennae. But Jimbriaris has oddly short, broad wings, while the others 

 are normal for Porosagrotis. Walker's species has the "locality un- 

 known."

detracta Wlk. 



HABITAT. Labrador; White Mountains; Montana; Colorado 12,000 

 feet, July 22 to August 12. 



The type of detracta is in the British Museum ; that of staudingeri I 

 have seen by the courtesy of Mr. Moeschler, and there are specimens 

 named by Moeschler in the Berlin Museum. Mr. Morrison's type is in 

 the Tepper collection. These all refer to one species, no specimens from 

 Colorado being in any collection. I have been unable to find any de- 

 scription for detracta Wlk., and it may be that the name will prove the 

 earliest if it is at all published. 



A. Colorado Smith.* 



1891. Smith, Trans. Am. Ent. Soc., xvni, 133, AgrotipMla, 

 HAITAT. South Park, Colorado.

 1891. Smith, Trans. Am. Ent. Soc., xvm, 133, Agrotiphila.

This genus connects Agrotis with Anarta, and emphasizes also the 

 Heliothine tendencies of Porosagrotis and Carneadcs.
