10 PEOCEEDINGS OF THE NATIONAL MUSEUM. vol. 64. 



margin which, joining the transverse one below, sets off a distinct 

 convex area at the upper part; callose posterior margin of meso- 

 pleurum broad and densely punctate; lateral abscissa of apical 

 propodeal carina distinct; areolet large and briefly petiolate; disco- 

 cubitus distinctly angulate and with a more or less distinct ramellus; 

 tegulae paler. Otherwise like longipes. 



Male. — Essentially like female but with a median facial spot and 

 tegulae yellowish. 



Type-locality. — Wellington, British Columbia. 



AUotype-locality. — Roque Bluff, Maine. 



Type.— Cat. No. 25975, U.S.N. M. 



One female, the type, taken July 28, 1904, and one male, the 

 allotype, taken August 10, 1907, by C. W. Johnson. 



NEOPROTARCHUS, new genus. 



In Schmiedeknecht's key to the Mesoleiina^" runs to the eury- 

 proctine genus Himertus Foerster, but differs from it by the charac- 

 ters distinguishing the subtribes Mesoleiina and Euryproctina, 

 especially by the possession of lateral fovae at the base of the 

 petiole and by the long hind calcaria. 



It is very closely related to Protarchoides Cushman, differing from 

 that genus by the medially dentate clypeus, wanting areolet, and 

 noncompressed hind tibiae and tarsi, as well as in the sculpture, 

 which is fine shagreening with punctuation on face and sides of 

 thorax; propodeal carinae wanting except apices of lateral carinae; 

 inner hind calcarium more than half as long as basitarsus; nervellus 

 broken far above middle and strongly reclivous; temples more 

 strongly receding; first tergite without dorsal median carinae. The 

 apical joints of the hind tarsi are missing from the unique specimen, 

 but from the general conformation of the rest of the legs it would 

 appear that they would be relatively longer than in Protarchoides. 



Genotype. — NeoprotarcTius ater, new species. 



NEOPROTARCHUS ATER. new species. 



Male. — Length 12 mm. 



Face densely, opaquely punctate; clypeus basally sparsely punc- 

 tate and more or less transversely striate; mandibles shagreened and 

 sparselj^ punctate; malar space half as long as basal width of 

 mandible; diameter of lateral ocellus two-thirds as long as ocell- 

 ocular line. Thorax practically impunctate dorsally, finely and 

 distinctly so on pleura and sternum; notauli not defined but repre- 

 sented by broad shallow impressions; scutellum convexly elevated, 

 not margined; speculum small, polished; propodeum opaque sha- 

 greened, laterally obscurely transversely striate, without carinae 

 except apical portion of lateral carinae, petiolar area poorly defined
