sumably light brown, the submedian lines sparsely haired. Scutellum 

 and post-scutellum presumably yellowish. Abdomen sparsely haired, 

 apparently yellowish, with a fuscous spot basally. Wings faintly spot- 

 ted near the middle of the third vein and along the branches of the 

 fifth ; subcosta uniting with costa near the basal third, the third vein 

 just before the apex, the fifth at the distal fourth, its branch near the 

 basal half. Halteres yellowish, reddish orange subapically. Coxae 

 yellowish; femora, tibiae and tarsi a variable fuscous straw; claws 

 slender, evenly curved, simple, the pulvilli nearly as long as the claws. 

 Genitalia ; basal clasp segment long, slender, with a small, triangular 

 lobe at the internal basal angle; terminal clasp segment somewhat 

 swollen basally ; dorsal plate long, deeply and triangularly emargin- 

 ate, the lobes rounded and sparsely setose ; ventral plate probably 

 broadly rounded, setose. Other structures indistinct. 



Larva. Length, 1.5 to 2 mm.; probably yellowish orange. Head 

 long, tapering to a narrowly rounded apex. Antennae slender, taper- 

 ing and with a length nearly twice the diameter of the head ; breast- 

 bone apparently wanting, ocular spot indistinct. Skin finely 

 shagreened, the segments dorsally, each with subdorsal, sublateral and 

 lateral setae near the anterior third, the longest having a length equal 

 to about half the body diameter; terminal segment reduced, with a 

 diameter about half that of the preceding segments and distally with 

 a median, rounded process. Conical, fleshy prolegs occur on body 

 segments 2-10. 



The above descriptions were drafted from balsam mounts 

 and the color characteristics as a consequence are hardly those
