constricted just cephalad the genital segment which is large and 

 prominent; the forceps are long and from the lateral aspect 

 are spatulate and attenuate at base ; the lateral arms are long 

 and tapering. The wing is broad and rotund and is decorated 

 with a dusky band. Figure 366. Lot 1347 Sub. 30 includes 21 

 specimens with data "Ottawa, Ont. 7-VI-1903 B. Meadow — 

 W. Metcalfe," and 3 specimens with data "27-VI-1903, W. 

 Metcalfe." LyOt 1339 and Sub. 24 includes 3 males with data 

 "17-20 June, 1904. Mud Creek, Tompkins Co., N. Y." 



The early stages are not known and the food plant is not 

 recorded. 



Aphaiara artemisiae angustipennis Crawford. 



This species as it exists in collections has a puzzling range 

 of variation which biological data may sometime help to clear 

 up. Fgures 363, 375, 376, and 386 are photographs of appar- 

 ently typical details.

Aphaiara comnmnis Crawford. 



Figures 365, 374, and 389 show a species as maddening in its 

 elastic variations as artemisiae. This is close to Z'caziei Patch 

 and biological data are needed to put on a satisfactory basis 

 either many closely allied species or a few species with a broad 

 and catholic taste in variation. 



Aphaiara sp. 



Figures 371 and 390 represent collections with rotundiform 

 wings that merge by gentle degrees too nearly with the com- 

 munis group to deal with in the absence of biological informa- 

 tion. 



Aphaiara sp. 



In the other direction traveling toward narrow winged speci- 

 mens with long branches of M and Cu is a series which also is 

 too flexible to separate satisfactorily and treat until ecological 

 information is forth coming An extreme of this scries is rep- 

 resented by figures 367, 373 and 381.
