Figures 25, 26 
The front of the basal joint of antennae is usually 
wholly black, but sometimes with two parallel stripes, 
face with two submedian black dashes, stripe on cheek 
ending with a black dash, upward. About 15 to 22 cos- 
tals, the third or fourth slightly sinuous ; the radius ex- 
tends far beyond end of subcosta so there are several 
(four or five) cross-veins from radius to margin; costal 
area not quite as broad as the radial area, radial sector 
for much of its length parallel to radius. The divisory 
cell is more than twice as long as broad, ends beyond the 
cross-vein, sometimes at end of second cubital cell; cubi- 
tal area at widest not two-thirds of marginal area at 
widest part, both narrowed to tip ; there are four or five 
outer gradates, rather widely separated ; in hind wing five 
to six outer gradates ; in fore wing the sectorals are 
curved, in hind wing several are sinuous. 
One specimen has two inner gradates in fore wing, near 
the radial sector. 
It is extremely common in northern parts of Mexico, 
and in desert regions in central and southern Mexico.
