No. 216. DOLICHOPUS ABSONUS. new species. 



Male. — Length 5-6 mm.; of wing 5.5-6 mm. Face wide, silvery 

 white, tinged with yellow above, a little narrowed below. Front 

 shining green, sometimes with blue reflections. Antennae yellow; 

 third joint a little longer than wide, obtusely pointed at tip, which is 

 sometimes a Uttle infuscated. Lateral and inferior orbital cilia 

 yellowish wliite, about six of the upper cilia on each side black. 



Thorax green or blue-green, with coppery reflections, which usually 

 form three vittae on the dorsum, the median one narrow and sharply 

 defined; dorsum a little dulled with gray pollen; pleurae with white 

 pollen. Abdomen green with coppery reflections; the white pollen 

 on its sides abundant and extending upon the dorsum. Hypopy- 

 gium black; its lamellae of moderate size, somewhat elliptical in out- 

 line, about twice as long as wide, whitish with a black apical border, 

 which is widest at upper corner, jagged and bristly at apex, fringed 

 above with a few black hairs. 



Coxae, femora and tibiae }-ellow. Middle coxae blackened a little 

 on outer surface; fore coxae with white pollen and delicate little 

 whitish hairs on anterior surface, sometimes with numerous little 

 black hairs along inner edge. ^liddle and hind femora each with one 

 preapical bristle, the hind ciliated with long yellowish white hairs 

 on lower inner edge for nearly their whole length; these hairs are of 

 nearly equal length, and not over one-half as long as the width of the 

 femora, sometimes much shorter than that, so they could scarcely be 

 called cilia. ^Middle tibiae with three bristles below, two near apical 

 and one at basal third, their basitarsi with one bristle near apical 

 third. Posterior tibiae only slightly thickened, the usual glabrous 

 stripe on upper surface distinct but narrow, the inner surface largely 

 glabrous, still the glabrous portion narrowing toward their tips and 

 reduced to a narrow line on apical fourth. Fore tarsi (fig. 216) 

 about one and a third times as long as their tibiae, the first two 

 joints taken together being as long as the tibia, second two-thirds 

 as long as first, both yellow; third joint with its basal half white, 

 apical half black, a little less than half as long as second, compressed, 

 fringed above with long dense black hairs which begin before the 

 middle of the joint, usually preceded by a single long Jiair nearer the
