Black, the abdomen with a blue tint, the wings uniformly bluish fuscous, with 

 violaceous tints, the nervures black; the 3rd cubital cellule shortly appendiculated, the 

 3rd transverse cubital nervure roundly curved, the 1st obliquely sloped, without a distinct

Base of mesonotum obliquely narrowed to a point, the sides straight. Sides of 

 metanotum broadly rounded, the apical slope not very steep. 3rd antennal joint about 

 one quarter longer than the 4th. The long spur of hind tibia? extends shortly beyond

Pompilus melaiiochrous, sp. nov. 



Black, the wings fuscous black, tinged with violaceous, the nervures black, the 

 radius distinctly projecting beyond the cubital cellules, the apical abscissa oblique, only 

 very slightly curved; the 3rd cubital cellule shortly, but distinctly appendiculated, the 2nd 

 transverse cubital nervure straight, oblique, the 3rd rounded; the 1st recurrent nervure 

 received near the base of the apical fourth, the 2nd in the middle of the cellule; the 

 transverse median nervure received very shortly beyond the transverse basal; the ac- 

 cessory nervure in hind wings very shortly before the accessory. Hinder ocelli separated 

 from each other by a distinctly less distance than they are from the eyes, which con-
