The following normally three-celled species are also occasionally 

 found in which one or both wings have but two submarginal cells: 

 bipunctata, claytonice, hippotes, platyparia, robertsonii, soliduginis, 

 personata, asteris, krigiana, milwaukeensis, etc. 



Since this table was finished, Dr. S. Graenicher, of Milwaukee, 

 Wisconsin, has published a paper in the Canadian Entomologist 

 June, 1903, pp. 162-166), in which five additional species are 

 described. As a remodelling of the table at this time is impracti- 

 cable, it may suffice to indicate briefly where these new forms would 

 fall: 



The species thaspii Graen., 9 , will come in the vicinity of frigida 

 Sm., or lauracea Rob., both of which it resembles in some respects. 

 Cockerelli Graen., 9 , comes nearest macoupinensis Rob., from which 

 it differs by having the facial fovere black instead of pale, and the 

 fimbria purplish instead of ochraceous. The male of Cockerelli 

 may be compared with perarmata $ , but lacks the tooth at base of 

 mandibles of the latter. Milwaukeensis Graen, 9 , is nearest to 

 impuncta Kby., but differs from it by having the pubescence on two 

 basal segments of abdomen ochraceous to fulvous, instead of whit- 

 ish. The male of this species has the pubescence entirely fulvous, 

 and the head extremely broad. The viburnella Graen., 9 , will fall 

 in the vicinity of rufosignata Ckll., and his albofoveata 9 seems to 

 come near platyparia Rob., and hartfordensis Ckll.
