surface of posterior wings is entirely black, wanting the yellow spots, as 

 well as the yellow hairs along internal margin. This may be a variety ; 

 I have insufficient material to determine its position ; such sexual dif- 

 erences have not been met with as yet in the genus. 



Hah if at. —Colorado Territory, Mr. J. Hidings. (Coll. Ent. Soc. Phil.) 

 The present species presents some resemblances to the description of 

 Anfhoecia bina, Guenee, but I infer that that species is generically dis- 

 tinct. 



If, in arranging the genera of the subfamily to which Anthoecia be- 

 longs, we precede this genus by Heliothis and allies, the following 

 seems to be the natural order of its species, all of which are known to 



me in nature. 



ANTHCECIA, Boisd. 



jaguarina, Guenee. 

 mortua, Grote. 

 Packardii, Grote. 

 nobilis, Grote. 

 lynx, Guenee. 



I separate from this genus Meltcleptria tuherculum, Hiibner, and 



Anthoecia hina Guenee, joining to them a third, hitherto undescribed, 



from Colorado Territory, under the generic name under which Hiibner 



described the first species, and which term is used in the " Verzeic- 



hniss" for the species o^ Heliothis.
