NKW SCOLIOIDEA. 



BY NATHAN BANKS, EAST FALLS CHURCH, VA. 



The following notes and new species apply to that section of 

 the fossoriai Hymenoptera, in which the pronotum reaches back to the 

 tegu'ai. Ashmead transferred them to the Vespids, in a superfamily, 

 but they have little affinity with them in most of their structure, and 

 most authors still keep them in association with the other fossoriai 

 Hymenoptera. 



PSAMMOCHARID.E 



Priocnemis Schiodte. — This name should be used instead of 

 Cryptocheilus in my table to genera (Journ. N. Y. Ent. Soc, 191 1, 

 p. 222). The type of Ci-yptocheilus is C. aimidatus and in this 

 species (which I have recently obtained) the hind tarsi have spines 

 below on the last tarsal joint; thus Cryptocheihis will replace Prioc- 

 ?ie??ioides, at least until this genus is divided. 



Priocnemis semitincia, n. sp. — Similar to P. arcuata, but the wings 

 are faintly uniformly tinged with yellowish, not darker at tip. The 

 spurs are nearly as dark as the legs, and the second recurrent vein 

 curved outward. The posterior margin of pronotum hardly angulate. 



Length 8 mm. 



From Las Vegas, N. Mex., 23rd July, 1902 (Oslar). 



Priocnemis directa, n. sp. — Similar to P. arcuaia, but the spurs 

 are about as dark as the legs (pale in P. arcuata) and the hind 

 margin of the pronotum is strongly angulate ; the wings are coloured 

 as in P. arcuata but the second recurrent vein is straight, not bent 

 near tip as in P. arcuata. 



Length 10 mm. 



From Lee Co., Texas, x\ug., Sept. (Birkman). 



Priocnemis mi7iorata^ n. sp. — Similar to P. conicus, and runs to it 

 in my table (Journ. N. Y. Ent. Soc, 19 11, p. ) but it has only 

 about eight teeth on the hind tibia above (in P. conicus there are 

 10) and in this species the teeth are not nearly as long as the space
