large ; i humeral, i presutural small, i small supra-alar, 2 

 post-alars, 4 scutellars, 2 noto-, i meso-, i sterno-pleural pres- 

 ent. Abdomen normal. Legs long, more or less character- 

 istically developed in male ; claws nearly straight ; pulvilli 

 wanting. Wings normal with post.c.v. straight but oblique. 



A well-marked genus based on the tufted arrangement of 

 the facial bristles which are not situated on the sides of the 

 face as is usual with the Ephydridae, but are confined to a tuft 

 on the hump between the antennae. Only one, the following 

 species, is known. 



Cirrula gigantea n. sp. 



Black with yellow halteres ; metallic-colored, mostly tawny to brown 

 pruinose. Frontal plate shining, bluish-green, sparingly dusted with 

 brown, with an elongate, narrow indentation just before the ocellar 

 tubercle, clothed with short, appressed hairs ; orbits very narrow, opake, 

 brown pruinose with two orbitals in a series of fine setulae ; f rontalia 

 distinct, opake, velvety brownish-black, much dilated anteriorly. Face 

 opake, golden brown with a shining metallic spot between antennal 

 foveae above; bristles as long as face; oral cilia few, long, laterally. 

 Checks concolorous, about one-third the height of head. Antennae with 

 third joint slightly longer than wide, conical ; arista bare, except the 

 thickened basal third pubescent. 



Mesonotum shining, but more or less obscured by brown dust ; an 

 approximated anterior pair and a widely separated posterior pair of 

 grayish stripes which are more or less opake in certain aspects. Scu- 

 tellum concolorous, convex, with a few marginal hairs which are hooked 

 at their ends. Pleurae below and metanotum grayish. Abdomen 

 somewhat shining, glaucous green with long, hooked hairs apically ; of 

 male narrower than thorax, rather long, with seg. 2-4 subequal, 5 about 

 one and one-half times as long as 4, triangular, rather acute apically ; of 

 female wider and shorter in proportion. Legs with anterior coxae 

 silvery gray; all femora greenish-tinged and brownish, distinctly haired; 

 male fore tarsi widely dilated and flattened, post-tibiae with an apical, 

 lateral flexor tuft of long, hooked bristle-like hairs, its basal tarsus 

 somewhat flattened and ciliate on lateral flexor margin, also evident on 

 the next joint; extensor surface of po-it-tibiac narrowly polished: 

 Wings brownish with costal sections I and 2 and veins I and 2 yellow. 

 Length 7-9 mm.
