space between the eyes; distinctly sulcate in the male; a little de- 

 pressed about the ocellus in the female. Eyes, large, prominent.

 long (female) as hind femora. Pronotum 

 rather long, faintly (male) or distinctly (fe- 

 male) widening on the posterior half; median 

 carina distinct and equal throughout; front 

 and hind margins truncate in the female, the

 separated in the female, less widely but never 

 touching in the male. Wings represented by a 

 slender oblong scale. Male abdomen well re-

 by an ivory white band which extends back from the cheek and covers 

 the lower half of the lateral lobe, and then curves down between the
