 ish-ferruginous spot on each side at tip ; wings blackish. 



Male. — Black, closely punctured, densely clothed with long black 

 pubescence; head entirely black; eyes small, round, entire and very 

 convex; antennae nearly as long as the head and thorax, black, the 

 flagellum sericeous. Thorax ovate, clothed above with long, dense, 

 yellowish-ferruginous or golden-yellow pubescence, beneath with black- 

 pubescence, as well as the metathorax which is broad, rather abrupt 

 behind and coarsely reticulated ; tegula? punctured, shining. Wings 

 ample, blackish, sometimes slightly paler about the middle, with a 

 longitudinal subhyaline streak in the second submarginal and second 

 discoidal cells ; marginal cell short, broadly truncate at tip and 

 not exceeding the tip of the third submarginal cell ; three sub- 

 marginal cells, the first longer than the marginal, pointed at either 

 end; the second as long as the marginal, pointed at base and greatly 

 narrowed towards the marginal, receiving the first recurrent ner- 

 vure about one-third from the base ; the third submarginal subob- 

 soletely defined, short, the tip extending beyond the marginal cell and 

 pointed, the side nervures descending almost parallel below the middle 

 to the cubital nervure, where the apical nervure becomes confluent with 

 the second recurrent nervure. Legs deep black, with black pubescence. 

 Abdomen oblong-ovate, gradually narrowed to the tip, black, somewhat 

 shining, closely and finely punctured, clothed above with dense black 

 pubescence, especially on the apical margins of the third and following 

 segments ; large basal segment clothed, except at base, with short dense 

 yellowish-ferruginous or golden-yellow pubescence, but not so dense as 

 to hide two large round yellowish-ferruginous spots, one on each side 

 behind the middle of the segment; these spots appear sometimes more 

 or less confluent, having the appearance of a broad band ; the node is 

 short and shining black, with sparse black pubescence except on the 

 apical margins of the segments where it is dense. Length 5 — 84 lines; 

 expanse of wings 9 — 13^ lines.
