This genus is allied to Contarinia and may be easily separated 
therefrom by the toothlike dorsal prolongation of the first antennal 
segment and the sparse clothing of narrow scales on the wing 
membrane. 
The type species, E. perfidus, isasmall form about 1.5 mm 
long, living as an endoparasite on Aphididae. The first antennal 
segment has a dorsal prolongation extending to the middle of the 
second, the third and fourth are fused, the fifth has the basal por- 
tion of the stem with a length about equal to its diameter, the distal 
part with a length nearly twice its diameter. The 
globose enlargements are nearly equal, each with 
sparse setae and moderately long, well-developed 
circumfili. The palpi are quadriarticulate, the 
fourth being one-half longer than the third. Sub- 
costa unites with the margin near the basal third 
and the third vein just before the apex of the wing,

and broadly emarginate. The ventral plate appears 
to be deeply and triangularly divided, the lobes tapering to a nar- 
rowly rounded apex; the style is long, slender and narrowly rounded. 
The female ovipositor is short, the lobes long, slender, fingerlike. 
The above characters are drafted from type specimens, generously 
donated to the museum by Professor Kieffer. An Indian species, 
E. hirta Felt,' was reared from Dactylopius on Mimusops, 
Tangalla, Ceylon. 

Endaphis americana Felt 
1git Felt, E.P. Ent. News, 22:129 
The first North American representative of this European genus 
was reared September 2, 1910 from what appeared to be galls of 
Eriophyes fraxiniflorae Felt on Fraxinus velu- 
tina collected by Dr R. E. Kunze, Prescott, Ariz., August 15, 
1910. There was no doubt as to the foliage having been deformed 
by Eriophyes, since mites were rather abundant and relatively 
large. There may have been a few aphids in addition. C.a2066.
