dorsal edge reliilively straight, equall}^ compressed throughout, 
rising abruptly from tlie flat disk, ami the incision nearly or quite 
vertical. 
The WINGS show decided differences. In oculatum the fuscous 
band renches the anal angle, but stops short of this in bolli; the 
apex of tlie wing is often deeply infuscated (fumose) in boUi^ 
especially the ^ , rarely so in oculatum (slightly maculate). 
The HIND femora show a difference on the inner side. In 
oculahiTYi the basal fascia is obsolete in tibial groove and is not 
connected with the next; in holli the proximal two are very 
broadly connected giving the appearance from below of a single 
veiy broad fascia. In oculatum the hind tibiap: may be 
slightly infuscated at base but are red beyond, often showing a 
pale annulus next to base. In holli they are black at base, beyond 
this a pale annulus followed by fuscous, and on the distal lialf 
coral red, sometimes infumated at tip. 
And finally the fuscous raaculations are more sharply outlined 
in ocula,tum than in bolli.

contracted to mere pinhead diameters. The superior incisors dw not fill
