Didactylomyia flava n. sp. 



The yellowish midge was taken on dogwood, Comus, at Albany, 

 N. Y., July 6, 1906. 



Female. Length 1.66 nun. Antennae about two-thirds the 

 length of the body, sparsely haired, dark brown, yellowish basally; 

 14 segments, the fifth with a stem about one-fifth the length of the 

 cylindric basal enlargement, which latter has a length fully three 

 times its diameter. Palpi; the first and second segments probably 

 short, rectangular, the third with a length three times its diameter, 

 the fourth only a little longer than the third, equally stout. The 

 produced face pale yellowish. Thorax and abdomen a nearly uni- 

 form bright yellowish, except for a dark, oval spot at the base of the 

 latter. Costa light yellowish, the slender though distinct crossvein 

 at the distal third of subcosta, which latter joins costa at the basal 

 third, the third vein uniting with the margin well beyond the apex. 

 Coxae pale yellowish, the posterior femora and tibiae yellowish 

 straw, the tarsi and other legs mostly dark fuscous; claws slender, 

 evenly curved; the pul villi nearly as long as the claws. Ovipositor 

 short, the terminal lobes biarticulate, the terminal segment narrowly 

 and irregularly oval, minor lobes short, stout, setose. Type Cecid.

This Argentine genus is provisionally referred to the Porricondy- 

 lariae, it being easily separated from Didactylomyia Felt by the presence 

 of a supernumerary vein at the base of subcosta, and the simple claws. 

 Antennae of the female with 14 segments, the third fused with the 

 fourth, the fifth subcylindric, with a length three times its diameter, 

 scarcely constricted and with a stem twice as long as thick. Palpi 

 quadriarticulate. Mouth parts one- third as long as the head. 

 Supernumerary vein, extends to the middle of subcosta, which latter 

 unites with costa near the middle of the wing and is joined to the 

 third vein by a very oblique crossvein; the fifth vein joins the pos- 

 terior margin near the distal third, its very short branch a little 

 before the basal half. The simple fuscous claws are twice as long 

 as the pulvilli. Ovipositor slightly produced, the lamellae short, 

 elliptical and thickly haired. This insect winters in a subglobose, 

 stem gall on Prosopis strombulif era. Type L. prosopidis
