pepsinae: tribe pepsini 81 



3. Propodeum with a strong sublateral longitudinal impression extending from 



the spiracle towards the apex; cubital vein evanescent just beyond the third 

 cubital cell; third cubital cell about 1.7 as long as the second cubital cell; 



oriental species Clistoderes (p. 83) 



Propodeum without a distinct sublateral longitudinal impression; cubital vein 

 usually reaching the wing margin; third cubital cell less than 1.5 as long as the 

 second cubital cell 4 



4. Outer hind corner of third cubital cell obtuse or approximately rectangular 



(pi. 2, figs. 22, 23, 24, 25); hind tibia of male without teeth; hind tibia of 



female with low, chevron-shaped teeth . . . Priocnemis (in part) (p. 89) 



Outer hind corner of third cubital cell acute (pi. 1, fig. 7; pi. 2, fig. 21) ... 5 



5. Hind edge of hind tibia of female with the teeth sometimes moderately strong, 



but usually weak or obsolete, between the teeth (when these are present) 

 the tibia is rather densely hairy; hind tibia of male lacking distinct teeth; 

 species of marsupial-like distribution. The only Nearctic species has the 



wings mostly orange Sphictostethus (in part) (p. 81) 



Hind edge of hind tibia of female with the teeth strong, between the teeth the 

 tibia polished and relatively or quite hairless; outer side of hind tibia of male 

 with distinct teeth Priocnemissus (p. 83) 



Subgenus Sphictostethus Kohl 



Sphictostethus Kohl, 1884, Verh. zool.-bot. Ges. Wien, vol. 34, pp. 37, 47. Type: 

 Pompilus gravesii Haliday; original designation. 



Haploneura Kohl, 1884, Verh. zool.-bot. Ges. Wien, vol. 34, pp. 37, 47 (preoc- 

 cupied; new synonymy). Type: Haploneura apogona Kohl; original designa- 

 tion. 



Haploneurion Kohl, 1885, Ent. Nachr., vol. 11, p. 163 (new name for Haploneura). 



In specimens with functional wings, the third intercubital vein 

 slants outward so that the thu'd cubital cell has its outer angle acute 

 (pi. 2, fig. 21); the third cubital cell is variable in size, usually about 1.2 

 as long as the second, and the cubital vein usually reaches the wing 

 margin. The wings of the females of some species are reduced, and 

 in these species there are various distortions from the normal venation, 

 including loss of the first intercubital vein. Upper edge of hind tibia 

 of both sexes without or with teeth, the teeth when present usually 

 weak, and never strong in the male; clothing hairs on upper edge of 

 hind tibia not more sparse than on the front face of the tibia; pro- 

 podeum without a sublateral longitudmal impression; male sub- 

 genital plate often with a longitudinal compressed tooth. 



I have seen a number of species from Chile, some from New Zealand, 

 one from Fiji, one from New Caledonia, five from Mexico, and one 

 from the Nearctic region. The Nearctic species (P. pretiosa) and 

 the five from Mexico form a distinct group which I shall call the 

 pretiosa group. The determined extralimital species that have been 

 examined are: Pompilus gravesii Haliday 1836; Salius (Priocnemis) 

 thaumastarius Kohl 1905; Pompilus flavipes Guerin 1836; Agenia 

 xanthopus Spinola 1851 ; Haploneuria apogona Kohl 1884 ; Haploneurion
