 from the apex of the cellule; nervellus in hind wings shortly ante- 

 furcal. The long spur of the hind tibia? is more than half the length 

 of the metatarsus. The 3 rd joint of the antennee is not one quarter 

 longer than the 4 Ul . 



Pompilus lukombensis sp. n. — Black, covered with a 

 pruinose hlue bloom; the antennœ, except the upper side of the 

 scape, which is black, and the lower side, which is yellow, and the 

 legs, except the coxte and trochanters, which are black, red; 

 the palpi of a lighter red; a line on the apex of pronotum, and the 

 apical 2 segments of the abdomen whitish yellow; the tibial and 

 tarsal spines black as are also the apices of the tarsal joints; wings 

 fulvous hyaline, the apex from the end of the radius fuscous viol- 

 aceous, the stigma and nervures fulvous; the 3 rd abscissa of radius 

 about one fourth of the length of the 2 nd , and about half the length 

 of the l st ; the 2 nd récurrent nervure is received in the middle of the 

 cellule; the nervellus interstitial; in the hind wings it is post- 

 furcal. cf.

Densely covered with a white pile. Glypeus wider than long, its 

 apex transverse. The postscutellar région and the apex of metano-
