APPENDIX 



By a, E. Grote. 



A collection made bj' Mr. Uhler has been submitted to me containing 

 the following species : — 



Mamestra discalis n. s. 



Allied to the eastern Mamestra nimhosa, of the same gray color and 

 large size. It differs by the space between the stigmata being clouded 

 with black, and by the reniform being wider inferiorly, much indented, 

 and narrower superiorly. The transverse posterior line is dentate and 

 not very distinct. The color is more purely bluish-gray, and the insect 

 looks in this respect more like the European nebulosa, but also differs by 

 the above characters. Claviform spot outlined in black. Hind wings 

 clear fuscous-gray, pale, with terminal black broken line, beneath 

 whitish, with faint median line, discal mark, and a distinct black ter- 

 minal line. On primaries, above, the black terminal points are smaller, 

 more cuneiform than in nebulosa. 



Length of primary 25™™. One specimen. Clear Creek Caiion. 



Mamestra olivacea Morr., var. 



A single specimen with the median space black, abdomen blackish, 

 hind wings fuscous, from Beaver Brook. Though darker, it is evidently 

 the same species as specimens sent me from Vancouver Island uoder the 

 ]Sro.^5579, and that I cannot separate except by their darker color from 

 eastern examples of olivacea. 



Mamestra sp. 



A single specimen from Clear Creek Caiion indicates a species distinct 

 from iUauclabilis Grote. Owing to the difficulty of the group, I am dis- 

 suaded from drawing up a description on this material. 



Mamestra {Dlanthcecia) meditata Grote. 

 Two specimens, Colorado Springs. 



Hadena arctica (Boisd.). 



One specimen, Clear Creek Canon. 



Stihadium s2)umosum Grote. 

 One specimen, Bijou. 



Khododipsa volupta. (Fitch). 



In liliodophora florida Guen., the fore tibiiie are provided with an 

 outer claw and two inner spines ; the joint is also furnished with
