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, is a small form about i . 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,

 d a p h i s am- basal half. The claws are long, slender, slightly

antennal seg- claws. Basal clasp segment rather long, slender, the

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.

 E . h i r t a Felt,^ was reared from Dactyl opius on Mimusops, 

 Tangalla, Ceylon. 



Endaphis americana Felt 



191 1 Felt, E. P. Ent. News, 22:129 



The first North American representative of this European genus 

 was reared September 2, 19 10 from what appeared to be galls of 

 Eriophyes fraxiniflorae Felt on Fraxinus velu- 

 tina collected by Dr R. E. Kunze, Prescott, Ariz., August 15, 

 igio. 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. a2o66.
