polished, the second tergite with only a faint suggestion of a trans- 

 verse impression; ovipositor sheaths fully as long as the body. Color 

 uniformly ferruginous, with antennae and palpi black, propodeum 

 sometimes more or less black; anterior and middle trochanters, some- 

 times their femora basally, all tibiae at apex, and all tarsi, blackish; 

 wings a little infumated. 



Type.— Cat. No. 28690, U.S.N.M. 



Type locality. — Arizona. 



Described from eight female specimens labeled "Ariz, 2122, Col-

 District of Columbia. 



28. BASSUS TERMINATUS (Cresson) 



Microdus terminatus Cresson, Proc. Ent. Soc. Phila., vol. 4, 1865, p. 298. 

 Orgilus terminalis Ashmead, Proc. U. S. Nat. Mus., vol.11, 1889 (1888), p. 640. 



Type. — The type of terminatus in the collection of the Philadelphia 

 Academy of Science; that of terminalis is in the United States 

 National Museum. 



There seems to be no basis on which to separate terminalis from 

 terminatus, and I believe they are the same species. The characters 

 given in the key will readily distinguish this species from laticeps, 

 which is apparently its nearest relative. 



Face broader than long; temples not l)ulging so strongly as in 

 laticeps and not nearly as broad as in that species; eyes a little larger 

 and extending to the vertex; malar space about two-thirds as long 

 as the eyes; clypeus not elevated anteriorly; labrum a little shorter 

 than in laticeps; third segment of labial palpi shortened but longer 

 than broad; antennae slender, usually 29 to 31 segmented; the 

 first flagellar segment four times as long as broad and longer than 

 the scape and pedicel combined ; parapsidal furrows sharply impressed 

 and finely foveolate; furrow in front of scutellum with several pits; 

 propodeum closely rugulose; hind femora rather stout; mesopleural 

 furrow straight, foveolate; inner spur of hind tibia longer than the 

 outer but less than half the basitarsus; posterior basitarsus distinctly 

 longer than half the hind tibia; apical segment of hind tarsi about 

 as long as the third; posterior tibiae short, tliickened at apex, 

 with a group of 10 or more short stout spines above the outer terminal 

 spur; areolet of fore wing triangular, petiolate; first abscissa of med- 

 iella distinctly longer than the second; nervellus angled above the 

 middle and emitting a distinct discoidella from this angle; first 

 abdominal tergite broad, closely finely striate, but without prominent 

 dorsal keels; second and following tergites polished; ovipositor sheaths 

 distinctly shorter than the body. Ferruginous; antennae black;
