and hind-wings distinctly more infuscated than the rest of the venation.

Male. Very similar to the female, but with the antennae slenderer, the 
two joints of the club practically equal in length, the wings narrower, with 
the discal pubescence somewhat sparser and the marginal fringe distinctly 
longer or nearly one-third as long as the greatest width of the disk. 
Coloration as in the female, except that the fuscous bands on the abdo- 
men are confined entirely to the basal half or a little more than half of 
abdomen, the fuscous cloud at base of wings somewhat paler.

Described from 21 females, 20 males (holotype, allotype, 
male and paratypes) mounted on slides and reared by Mr. 
Swezey from the eggs of Sogata paludum (Kirkaldy) collected 
at Kewalo in Honolulu on August 18, 1913, and on May 4, 
1914; and 14 specimens (paratypes) of undetermined sex, 
mounted on cards and reared with the preceding specimens.
