not going below level of antennae. Flagellum bright red beneath,

 Mesothorax and scutellum dullish, closely punctured; area of meta- 

 thorax hardly sculptured. Tegulae light reddish. Wings dusky, 

 paler basally. Only two submarginal cells. Stigma very small. 

 Basal nervure meeting transverse median. First recurrent nervure 

 joining second submarginal not far from its beginning. Hair of legs 

 light reddish, dense on tibiae and tarsi. Abdomen shining, well 

 punctured, the broad depressed hind margins of segments pale tes- 

 taceous, and above this a ferruginous band which is linear on first 

 segment and successively wider on the others, until on the fourth 

 and fifth it forms a patch covering the most of the middle of the 

 segment. All the segments with thin but entire bands of long yel- 

 lowish hair, and much of same hair at apex, second segment in middle 

 depressed scarcely one- third. The male has clypeus entirely yellow
