The genus appears best separable from Graphiphora on genitalic char- 
acters and the lack of any apparent thoracic tufting. Of our North Ameri- 
can species, the writer includes here calgary Sm., cynica Sm., rubifera Grt. 
(which has not been examined, but of which cynica may prove a synonym), 
dislocata Sm. (probably a North American form of the European f estiva), 
jucunda Wlk., esurialis Grt., and hospitalis Grt. (not examined, but prob- 
ably a synonym of the European brunnea Schiff.). Also, for the present, 
rosaria Grt. may be placed here; this species is decidedly atypical in form 
of genitalia and is very close to the European rubi View, (vide Pierce, 
op. cit., PI. 18 for figure of genitalia). 
Graphiphora Ochs. 
1816, Schmett. Europ. IV, 68 (type, c-nigrum Linn.). 
Amathes Hbn., 1822, Verz. bek. Schmett. 222 (type, baja Schiff.). 
Megasema Hbn., 1822, Verz. bek. Schmett. 222 (type, triangulum Hfn.). 
Lytaea Steph., 1829, 111. Brit. Ent. Haust. II, 107 (type, sexstrigata Haw.). 
Segetia Steph., 1829, 111. Brit. Ent. Haust. II, 153 (type, xanthographa Schiff.). 
Very similar to Diarsia Hbn., but with smoother and sometimes 
scalier thoracic vestiture and better-developed thoracic tuf tings; the fore- 
tibial spining is weaker and at times entirely hidden in hair.

Group I 
Male Genitalia. Clasper typically of even width throughout, at times 
somewhat bulging on ventral margin; apex more or less rounded; corona 
lacking, but frequently replaced by spine-like hairs; pollex present; 
ampulla absent; harpe rather weak, scarcely exceeding costal margin, but 
with foot-like base long and attached to ventral margin of clasper. Uncus 
narrow and pointed. Clavus absent. Juxta strong, variable in shape. 
Vesica with variable armature as in Diarsia.
