specimens seen. The posterior margin of the pronotum is a little more angu- 

 late than in the typical form. The comb on tarsus I is of the same long, 

 broad spines, the vertex straight across, the abdomen with two segments below 

 and two and a half above reddish, and the body (except propodeum) hairy as 

 in the typical form. 



Pompiloides reducta new species. 



Related to P. marginatus, but antennae shorter, and the vertex broader. 

 Female. — Black ; head, especially the clypeus with dull tawny pile, very few 

 hairs except on orbits, pro and mesonotum also show tawny pile, second seg- 

 ment of abdomen mostly or wholly reddish above, tarsi dark brown ; wings 

 blackish, nearly evenly colored throughout, hind wings dusky. Clypeus trun- 

 cate on margin, face scarcely narrowed above, vertex nearly straight across, 

 posterior ocelli plainly nearer to eyes than to each other ; antennae with third 

 joint plainly a little longer than the fourth, the second and third together 

 do not equal vertex width ; pronotum slightly angulate behind, metanotum 

 with a faint median line ; abdomen rather shorter than in P. marginatus. 

 apical and ventral segments with long hairs ; tarsus I without distinct comb, 

 the spines hardly as long as width of the joint; inner spur of the hind tibiae 

 about two thirds as long as the metatarsus. Wings with the venation similar 

 to that of P. marginatus, but the second discoidal cell is hardly as long as in 

 that species. Length, 8 mm. 



From Falls Church and Glencarlyn, Va., and Ridgeway, Ontario, 

 Canada (Van Duzee), latter part of June to early August. 



Pompiloides stenotus new species. 



Black, rather shining, with silvery sheen, very distinct on face, pleurae, 

 coxae, and metanotum. Clypeus truncate on margin, vertex scarcely rounded, 

 posterior ocelli hardly nearer to eyes than to each other ; pronotum angulate 

 behind ; metanotum with faint line in middle, abdoftien very slender, no promi- 

 nent hairs below, last dorsal segment with a pair of tufts of short hair near 

 the middle of hind margin ; legs slender, with very few, short spines, hind 

 tibiae with only three in row above, the inner spur about two thirds as long 

 as the metatarsus. Wings blackish at tip, but nearly hyaline elsewhere, third 

 submarginal petiolate, receiving the second recurrent beyond the middle. 

 Length, 7 mm. 



From Bradcntown, Florida, March (Van Duzce). 



Pompiloides clystera ntw species. 



Male. — Similar to P. cylindricus. Deep black, but not silvery. Under 

 each antenna, above base of clypeus, there is a patch of tawny brown hair 

 each side ; clypeus truncate on margin ; head narrow, posterior ocelli plainly 

 a little nearer to the eyes than to each other, vertex slightly, evenly rounded, 

 occiput with black hairs, antennae plainly heavier than P. cylindricus; pro-
