ART. V -NOTES ON A COLLECTION OF NOCTUID MOTHS MADE 

 IN COLORADO IN 1875 BY DR. A. S. PACKARD, JR. 



By Aug. E. Gkote. 



A small collection of Xoctnidw made in Colorado is here determined. 

 It is doubtful that it oiiers anything peculiar to the region, so little is 

 known with regard to the distribution of our Noctuidcc, although a new 

 species of Sadena is here described. The species of Agrotis noted have 

 a wide range. A single Anarta indicates a new species, but the speci- 

 men is imperfect. No species of Oncocnemis are included. This genus 

 is interesting from its distribution. Lederer, in 1857, recorded four spe- 

 cies from the Ural and Altai. From collections made in Colorado by- 

 Mr. Theo. L. Mead, I was enabled to announce the discovery of the 

 genus in Xorth America (Bulletin Buifalo Soc. Nat. Sci., i, 105 et seq.). 

 I have described four species from Colorado, two of which, Jiayesi and 

 (?«]//, have yellow secondaries, like the species of Agrotis, formerly referred 

 to TripJucna. We have this yellow color to the hind wings constantly 

 recurring in different genera in this group. In 2Iamestra, we have 31. 

 flava Grote; in Anarta, A. cordigera, with yellow secondaries. Besides 

 these four species of Oncocnemis, a fifth, which I have not seen, has been 

 described from Colorado, under the name of 0. meadiana Morr. Of 

 these five species, the range of 0. chandleri Grote has alone been ex- 

 tended by subsequent discoveries. Mr. Fred Tepper has taken on Long 

 Island specimens which I refer to this species, and it has occurred in 

 the vicinity of Buffalo, N. Y. 0. chandleri seems to offer a variation 

 in the distinctness of the markings of the primaries without the possi- 

 bility of establishing intermediate grades j the typical specimen was 

 strongly marked Avith black ; the eastern material, being faintly marked, 

 has unnecessarily given rise to a varietal name. In addition, I have 

 described a Californian species, 0. hehrensi, allied to the European 0. 

 confusa. I add here a new form from Nevada. 



It has also been found by Dr. Harvey that Copiliadena atricoUaris 

 from Texas belongs to this genus ; while another species. One. angustus 

 Harvey, has been described from the same locality, while I have added 

 to the genus 0. occata Grote from Texas and California, and 0. saun- 

 dcrsi Grote from Ontario, Canada. As thus constituted, we have eleven 

 North American species, separable generically from Agrotis Hilbn. by 

 the middle and hind tibia) being without spinules, and by the anterior 

 tibiie being provided with a terminal claw; and from Adita Grote by
