3Iale. — Front 0.24 of the head width (average of five. 0.28. 0.24, 

 0.24, 0.24, 0.25); parafrontals with yellow pollen; parafaoials but 

 little paler: frontal bristles just meeting the large bristles of the 

 facial ridges; antennae black; tip of second joint slightly reddish, 

 the third joint rather long and slender, about three times the second; 

 arista thickened on the basal two-fifths; bucca about one-.sixth the eye 

 height ; palpi yellow ; .proboscis small. Thorax with the usual rather 

 dense yellowish gray pollen, four black stripes veiy distinctly visible 

 on the dorsum when viewed from behind: dorsocentrals 4, sterno- 

 pleurals 3, scutellum distinctly yellow at tip; the steniopleurae near 

 \vhere they join each other on the middle line bear large clusters of 

 long, curved black bristles bending backward, these join with a few 

 of similar size and shape on the middle coxae to form a single or 

 slightly divided tuft which is very conspicuous and occurs in males of 

 several species related to this one. Abdomen broadly yellow begin- 

 ning on the first segment and extending continuously to the last third 

 of the third segment, only a broad stripe in the middle black in ground 

 color, the yellow gray pollen of these segments is confined mostly to 

 the area next to the middle stripe and to the lateral nuirgin: fourth 

 segment with dense whitish pollen on the anterior half, divided on 

 the median line by a very distinct shining black stripe, posterior 

 half of the segment shining black; discal bristles absent on the la^t 

 segment; first and second each with one pair of median marginal 

 bristles: third segment with a marginal row of about eight; fourth 

 segment with numerous bristles and bristly hairs on the apical half, 

 (xenital segments blackish, the united inner forceps forming a long 

 slender prooess, curved at tip, flat behind except near the base where 

 it is rounded and kneeled; outer forceps modified into flat reddisli
