tibiis tarsisque ferrugineis ; alia hyalinis, pallidissime flavo- 

 tinctis, venis ferrugineis. 

 Long. 13 mm. 



^. Clypeus very broadly rounded at the apex; vertex 

 sparsely punctured. Eyes separated on tlie vertex by a 

 distance only slightly exceeding half the length of the 

 second joint of the tiagellum ; median segment about half 

 as long again as the scntellum. Second sternite shining, 

 evenly, but not very closely punctured ; seventh tergite 

 broadly subtriangular, rather broadly truncate at the apex, 

 and clothed with silver pul)escence faintly tinged with gold; 

 eighth sternite widely and rather shallowly emarginate, the 

 angles produced into distinct teeth. Third abscissa of the 

 radius longer than the second, but shorter than the distance 

 between the recurrent nervures on the cubitus. Third 

 cubital cell very little shorter on the cubitus than the second. 

 Basal joint of fore tarsus with five spines.
