 long, with distinct median groove ; abdomen depressed, elongate, last segment 

 rather broad at tip, no brushes of hair on venter ; legs very slender, weakly 

 spined, long spur of hind tibia nearly three fourths of metatarsus; wings 

 rather pale, but black beyond cells, second submarginal with oblique sides, 

 third triangular, receiving the second recurrent beyond middle, this vein very 

 oblique, and arising before middle of anal cell. 

 Length 8 mm. 



From Black Mt., N. Car., May; Chain Bridge, and Great Falls, 

 Va., June. 



Larger than P. cyUndricus, with distinct groove on metanotum, 

 and larger ocelli. 



Pompiloides minora, new species. 



Fcnicile. — Deep black, clypeus slightly silvery. Clypeus broad, truncate 

 below, bristles very weak or absent; antennae short, no hairs on basal joint, 

 third joint very short, not longer than first, not one half the width of vertex, 

 no distinct line to anterior ocellus, this fully twice its diameter from the 

 laterals, these as far from eyes as from each other ; vertex slightly convex ; 

 head hairy ; pronotum arcuate behind ; metanotum short and broad, no distinct 

 median line ; abdomen shining above, last segment hairy ; legs moderately 

 spined, spines of tarsal comb one and one half the width of joint, long spur of 

 hind tibia two thirds of metatarsus ; wings uniformly black, second submarginal 

 square, third triangular, receiving the second recurrent beyond middle, this 

 vein arising from about middle of anal cell. 



Length 6 mm. 



From Falls Church, Va., 2 Aug., and Southern Pines, N. Car.', 

 8 July (Manee). Distinct from the female of P. cyUndricus by the 

 very short third joint of antennae. 



Pompiloides parvulus, new species. 



Female. — Black ; only slightly silvery on the clypeus and metanotum ; man- 

 dibles reddish in the middle ; wings black, usually darker on tip than else- 

 where. Antennae rather short, but slender, the third joint fully three times as 

 long as broad, and a little longer than the fourth joint; a line up to anterior 

 ocellus, this a little more than diameter from the equal hind ocelli, the latter 

 nearly as close to each other as to the eyes ; face about as broad above as 

 below, vertex slightly convex ; pronotum distinctly angulate behind, metanotum 

 sloping, with a median furrow ; abdomen not much longer than thorax, cylin- 

 drical, hairy near tip ; legs distinctly spined, but spines on the hind tibia are 

 not as long as width of the joint ; long spur of hind tibia reaching a little beyond 

 middle of the metatarsus ; tarsus I with usual comb of short spines. Wings 

 with second and third submarginal cells subequal (or even third smaller), 

 both subtriangular ; marginal cell short, oblique at tip ; first recurrent meets
