brownish-red. Antennae wholly black, including arista. Palpi reddish- 

 yellow, the constricted basal half blackish, the tips feiintly and indistinctly 

 dusky. The usual four narrow dark vittae on thorax. Scutellum and 

 hind angles of mesoscutum reddish-honey color, but pollinose jind not 

 conspicuously departing from general shade of coloration. Four postsu- 

 turaJ and two postacrostichcJ bristles, the hindmost of latter wanting. 

 Scutellum with three lateral subappressed macrochaetae on one side and 

 two on the other, no apical pair; discals erect and spinelike, in about 

 three transverse rows. Tergum of abdomen wholly olive-golden, only a 

 black patch on each side of apical half of anal segment. The first two 

 segments have no marginal macrochaetae other than the lateral ones, 

 except that second segment has a median marginal row of six with two 

 shorter median pairs between the three on each side, one pair in front of 

 the other ; second segment with a discd subarcuate row of eight reach- 

 ing front border of segment on median line, with a short median pair 

 behind row ; third segment with discal arcuate row of eight, and two 

 short ones in middle between the four on each side, also with thickly set 

 marginal row which becomes a double row at sides of segment; apical 

 half of anal segment with a geminate bunch of marginal to discal macro- 

 chaetae, the bunch being emarginate in middle anteriorly, and a medizm 

 transverse row of four a little in front of the same. At sides of the seg- 

 ments the black of venter shows narrowly. Wings infuscate ; tegulae 

 similarly infuscate, the hind scale neirrowly yellowish on meurgin. Claws 

 and pulvilli yellow, tips of former black. Proboscis when extended dis- 

 tinctly longer than head-height, the part beyond geniculation not espe- 

 cially stout. The anal segment of abdomen is rapidly tapered to a very 

 narrow tip, and is not at all emarginate apically. No ocellar bristles. 

 Third antennal joint is about one and one-half times as long as second, 

 widened, rounded-truncate apically.
