except ends, tlie cnbitals and gradates also black. Six 
cubitals beyond the divisory cell, latter about three times 
as long as broad; five or six gradates in each series, 
nearly parallel, and the inner nearer to radial sector 
than to the outer row; radial area much broader than 
costal ; the cubital area about two-thirds of the marginal 
area. In hind wings five or six gradates in each row, 
about parallel, and inner nearer to radial sector than to 
the outer row; the inner row disjoints the sectorals in 
both front and hind wings; the costal cells much longer 
than high. 
Length fore-wing 14.8 mm., width 3.4 mm.

Head pale, with pale red marks on face and vertex; 
face broad, a narrow band below antennae, making two 
curves, a broad red spot below each eye; in middle a 
transverse mark rounded above and with two projections 
below, enclosing a median pale spot. On vertex a mark 
starting between the antennae, giving off each side a 
streak to margin upper edge of antennal sockets, shortly 
behind the median streaks forks again, and each fork 
gives off a branch to the eye, the fork still curving out- 
ward and reaching the hind border, each end being fully 
twice as near to eyes as to each other. 
The pronotum shows no definite markings, but the 
lateral lobes of mesonotum are partly suffused with red- 
dish and some faint reddish in some of the grooves. Ab- 
domen dark above (possibly reddish alive). 
Wings with pale veins ; in fore wings the gradates and 
many cross-veins pale brown, some almost margined. 
Costal area almost half as broad as radial area ; 18 cos- 
tals before stigma, none sinuous, cells about as long as 
high; divisory cell is very broad, not twice as long as 
broad, the oblique base occupies about three-fourth of
