sparse. A male from Aquada, Panama (Sturtevant), has brown 

 legs and wing-veins. The hypopygium is globose but not larger 

 than the abdomen. 



Eudrapetis nuda, sp. nov. 



Length l.G mm. Shining black, pubescence pale, short and very 

 fine, legs devoid of bristles, yellow, the hind femora largely black. 

 Occipital orbits white-poll inose; eyes separated above the antennae 

 nearly as much as the width of the second antennal joint, front sub- 

 shining black; face gray, linear in the middle, cheeks one-tenth the eye- 

 height, their lower edge horizontal; palpi white and with a terminal 

 white hair, proboscis brown; basal joints of the antennae yellow, the 

 second joint with a seta beneath, the third joint lanceolate, fuscous, 

 two-thirds longer than broad, with short pubescence, the terminal arista 

 nearly bare, two times the antennal length. Thorax closely covered 

 with short and very fine white hairs, no evident dorso-centrals on the 

 disc, four scutellars, pleurae with gray tomentum following the noto- 

 pleural and the meso-sternopleural sutures. Abdomen subopaque 

 black, its short sparse hairs black, hypopygium of moderate size, shining, 

 with white hairs beneath, the left side with a trifurcate process. Legs 

 simple, without spines or bristles, hind tibiae not spurred, the last tarsal 

 joint a little darker. Halteres yellowish. Wings hyaline, veins thin, 

 brownish, the third and fourth veins rather strongly convergent, the 

 fourth vein curving forward toward its tip, second vein shorter than 

 usual, the second, third and fourth sections of the costa proportioned 

 L3 : 4.5 : 1, outer sections of the fourth vein proportioned 1 : 6, of the 

 fifth vein subequal, marginal cilia uniformly short. 



Numerous specimens: Kamerun. West Africa, received 

 from Professor Roland Thaxter. 



Eudrapetis oedimera, sp. nov. 



cf. Length 1 mm. Shining black, with brown legs, black antennse, 

 blackish palpi, dirty white halteres and strong dark brown veins; hind 

 femora with a pronounced swelling beyond the middle of the anterior

 oval, scarcely longer than wide, its arista long and slender, measuring 

 four times the antennal length, microscopically hairy. Vertex broadly 

 polished, ocellar triangle prominent, occiput slightly dusted, the lower 

 orbits and the lower front only inconspicuously cinereous, face linear, 

 black. Hairs of mesonotum very sparse, brownish, those of the dorso- 

 central rows long, scutellum somewhat dusted; pleurae entirely polished; 

 abdomen nearly bare, largely shining, pygidium small, elliptical in 

 outline, sparsely hairy. Anterior tibiae with fine apical bristles, hind 

 femora with two apical bristles on the anterior side, hind tibiae without 

 extensor bristles but with a group of three at the tip, metatarsi not 

 setulose. Wings hyaline, veins broad, the fifth vein evanescent midway 

 between the posterior cross-vein and the margin, first four veins with a 

 slight anterior curvature, the third and fourth veins nearly parallel,
