vein 9 remote from 1 0, close to end of cell ; vein 6 from upper 

 angle of cell ; upper discocellular minute ; middle discocellular 

 erect, lower slightly inwardly oblique, the lower rather the longer ; 

 vein 3 well before end of cell, about equidistant from 2 and 4, and 

 twice as far from base of wing as from end of cell. Hind wing 

 triangular, hardly lobed at anal angle ; vein 7 three times as far 

 from 8 as from 6 ; discocellulars faint, erect ; vein 3 well before 

 end of cell, twice as far from 2 as from -1 ; vein 2 slightly nearer to 

 end of cell than to base of wing. Hind tibiae with two pairs of spurs 

 and with a long tuft of coarse hairs attached nenr the proximal end. 

 E. ffiffas, Mab., the type of Eurjiptenis, is not in B. M., but as 

 the other two species, viz. lavochrea, Butler, and coracina, Butler, 

 which M. Mabille puts into his genus, are congeneric with elevsinia, 

 Hewitsou, the type of ^Ethilfa, therefore ffiffi's also is presumably 

 an Mthilla.

Type, Jiiarbas, Cramer. 



Antennae : club very slightly thickened, bent at more than a 

 right angle, tapering to a fine point, the front edge of club friuged 

 with short widely set bristles. Palpi : third joint almost invisible. 

 Fore wing : inner and outer mai-gins subequal ; no costal fold in 

 male; cell well over two-thirds the length of costa ; vein 12 

 reaching costa well before the end of cell ; discocellulars suberect ; 

 vein 5 slightly nearer to 6 than to 4 ; vein 3 well before end of cell, 

 more than twice as far from 2 as from 4 ; vein 2 remote from 3, 

 twice as far from end of cell as from base of wing. Hind wing : 

 vein 7 shortly before end of cell ; discocellulars very faint, slightly 

 inwardly concave ; vein 5 just traceable, nearer to 6 than to 4'; 

 vein 3 immediately before end of cell ; vein 2 only slightly nearer to 

 end of cell than to base of wing. Hind tibise with two pairs of spurs, 

 the upper pair minute, and with a tuft of hairs attached near the 

 proximal end.
