This small species may be at once recognized by the dark 

 spots on the wings, one round one at the base of fork of 

 third vein and another at apex of discal cell ; there are also 

 dark blotches on the cross-veins and the fore border is 

 brown. Forehead parallel, covered with ashy-grey tomen-

 (7) v. pp. 112, 116, pi. i. fig. 10 (1900). 



A series of females in Mr. Wainwright's Coll. from 

 Herberton and Kuranda, Queensland (F. P. Dodd). 



The forehead in this species is almost half as wide again 

 anteriorly as it is at vertex, covered with yellowish-brown 

 tomentum and with some short black hairs ; frontal callus 

 indistinct, small, pear-shaped, reddish or brown, when de- 

 nuded a long dark stripe is visible.

E. maculipennis, Macq., from east coast of New Holland, 

 must be nearly allied to this species, but the description 

 speaks of the legs being chiefly reddish ; the wings have an 

 appendix, and white hairs are present on the sides of most 

 of the segments ; the length given is 14 mm., and black 

 median spots are said to be present on the first two 

 segments.
