Evans — Neotropical Pompilidae 
269 
bright rufous except coxae mostly black, tarsi weakly infuscated; 
middle and hind legs black except coxae white at apices, tibiae 
spotted with white near the base, spurs whitish. Wings hyaline, 
fore wings with a weak band at the basal vein and a weak spot at 
the second and third submarginal cells. Clypeus arcuately con- 
cave. Malar space 0.6 X as long as width of mandibles at their 
base. Front broad, middle interocular distance 0.61 X head width; 
upper interocular distance 0.94 X lower interocular; eyes densely 
hairy; postocellar line twice the ocello-ocular line. Third an- 
tennal segment 0.48 X upper interocular distance. Pronotum 
moderately long, broadly angulate behind; postnotum a very 
narrow band; propodeum sloping evenly in profile. Front femora 
2.6 X as long as wide; hind tibia with only very minute spines. 
Fore wing with transverse median vein located very slightly basad 
of basal vein; radial vein strongly angulate at second intercubital 
vein; maximum width of third submarginal cell 1.45 X that of 
second submarginal; hind wing as in preceding species. 
Remarks. — This species is known only from the type, which 
is quite unlike any other species of the genus. It is a member 
of the azteca species-group, and will run to couplet 5 of my 1967 
key, separating inca Evans and jocosus Evans. The wing vena- 
tion is very similar to that of those two species, but the banding 
is much weaker; there are important differences in body color 
from both species. E. inca is a larger species, with the postocellar 
line only 1.6 X the ocello-ocular line and the postnotum more 
broadly exposed, while E. jocosus has the postnotum concealed 
dorsally and the tibiae more evidently spinose. 
Epipompilus tucumanus Evans 
I described this species in 1967 from a series from Argentina 
as well as one female from Venezuela. A single female was col- 
lected in Bolivia by Porter, Stange, and Demarest, at Buena 
Vista, Dept. Santa Cruz, 8-26 July, 1973 [Coll. C. C. Porter], 
Epipompilus nigribasis (Banks) 
I have reported this very small species from Panama, Colom- 
bia, and Brazil. In the Canadian National Collection there is a 
pair from Canuaru, Pernambuco, Brazil, collected in April, 1972, 
by M. Alvarenga. Porter and Stange have also collected this
