226 THE CANADIAN ENTOMOLOGIST. 



July and September. The species is one of the most characteristic of the 

 series and easily recognized. 



Rhynchagrotis fiiger, Sm. 



Uniform, very dark smoky-brown, collar without lines or marks, 

 transverse maculation of primaries almost lost, the ordinary spots marked 

 only by the black filling in the cell ; orbicular open to the costa. The 

 species is very characteristic, but I have only the types — one from 

 Pullman, Washington, the other from Moscow, Idaho, the former in May, 

 the latter in July. 



Rhynchagrotis ema?-gi?iata, Grt. 



I have 2 (^ 's and i $ that I have separated ivom for??ialts, and 

 which agree with a figure made from the type of emarginata. There are 

 specimens of fonnalis so close to this at first sight that I failed to 

 discriminate between them in 1892, and Sir George F. Hampson has, more 

 recently, fallen into the same error. Emarginata differs from the most 

 evenly-coloured for?naiis in having the transverse lines maked on costa 

 by geminate black dots, the costal area is not in the least paler, and there 

 is no difference in tint between the base and upper portion of collar. In 

 all these points my specimens and the drawing agree, and I have therefore 

 restored Mr. Grote's name as referring to a good species. 



Rhynchagrotis /net a, Sm. 



Of this neat litde species I have only the two typical examples. It 

 is very pale fawn-gray, washed with reddish, the median lines darker brown 

 or even blackish. The costal area, while not paler, is of the palest gray 

 on the wing, and the ordinary spots are defined by the reddish washing 

 around them. The orbicular is V-shaped, open to the costa and like it in 

 tint. The extreme tip of the collar is black, else the head and thorax are 

 a rather rusty-red. 



Rhynchagrotis niirabilis, Grt. 



Easily known by the discolorous yellowish reniform and the black 

 streak through cell and below median vein — a somewhat variable feature, 

 by the bye. The disc of thorax is also more or less discoloured, as a rule, 

 with lateral black lines to the discoloured area. 



Rhyfichagrotis v art at a, Grt. > 



Begins the series in which the ordinary spots are small, not dis- 

 coloured ; the orbicular round, or nearly so, and always complete, not 

 open to the costa. The present species is perhaps the largest and
