Wings broad, the apical margin rounded ; whitish-hyaline, thickly covered^ 
large and intensely black spots. In the anterior wings there are about 25- 
more or less rounded spots, some of those on the costa being confluent, and , 
forming transversely elongate, cuneiform dashes; the margins are regularly spot 
the d,sc with two irregular longitudinal rows, those placed on the two ro.- 
gradate veinlets often united into interrupted transverse streaks ; in the posle 
wxngs the discal spots are less numerous. The margins (especially the cos 
and all the veins are strongly ciliated with black. The longitudinal and mosi 
the transverse veins and veinlets in the basal half of the wings are whitish yell 
excep where they traverse the spots, when they become black; most of 
grada e vemlets and of the longitudinal apical veins are black (but the first 
gradate veinlets in the outer series are white in the middle, even although thev 
p aced in the black spots) ; the sector about 10-branched in the anterior ^ings: 
pterostigmatical region in all the wings is .slightly tinged with yellowish. 
This beautiful and striking species was collected in 1S69 
Trebizond, by M. Th. Deyrolle. In structure it is much h 
0.^/}dv^cephalus (chysops, Auct.;, but has shorter and broader win. 
with the apical margin slightly rounded, instead of slightly excise 
hence the apex is less produced. The net-work of the wings is rath 
more open, and the series of gradate veinlets more parallel.
