THE CANADIAN ENTOMOLOGIST. 



345 



nose-like prominence of the front being common to all, with the following 



limitations : 



Nasusina, n. gen. 



Type inferior, Hulst. 



Variable. 

 Thorax, untufted. 



Abdomen, with low tufts, or none. 

 Venation, hind wings, 6 and 7 



long-stemmed, 3 and 4 widely 



separate. 

 Accessory cells, one. 



Fixed. 

 Antennas, flattened, shortly ciliate, 



slender. 

 Palpi, moderate. 

 Front, horizontally projecting, with 



pad or cushion of scales, 



rounded above clypeus. 

 Tongue, developed. 

 Fore tibiae, unarmed. 

 Hind tibiae, end spurs normal, 



upper spurs much reduced, or 



absent. 

 Hair pencil in ^ absent. 

 Venation, hind wings, vein 5 pres- 



ent, vein 8 anastomosmg 



with cell nearly cell's length. 



The species at present recognized are : 



inferior, Hulst. 



desperata, Hulst. 



remorata, Gross. 



gypsata, Hulst. 



discoidalis, Gross. 



artestata, Gross. 



mellissa, Gross. 

 The type form is constant so far as I can determine, but the species 

 are rare in all collections. Of the type, I have not seen more than twenty 

 examples, ten of which are in my own cabinet. 



Eupithecia, the central genus, should be left for later assemblage into a 

 series of groups or sections,"having as a basis for separation, for instance, 

 the biciliation of the antennae as in the lachrymosa group, or even minor 

 characters, some one thing which will serve 1:0 include an orderly series. 

 For the present this is impossible, until the species themselves are 

 determined, and especially does this apply to the many forms inhabiting 

 our western territory.
