peural entirely polished ; mesopleural furrow shallow, poorly defined, 

 smooth; coxae smooth and polished; inner spur of hind tibia not 

 distinctly longer than the outer, nearly half as long as the basitarsus; 

 radius arising from the middle of the stigma; areolet triangular, 

 strongly petiolate; first abscissa of mcdiella just about equal to the 

 second; nervellus straight; discoidella wanting; fu-st abdominal ter- 

 gite a little longer than broad at apex, more or less striate medially 

 and with two prominent dorsal longitudinal keels on the basal two- 

 thirds; second and third tergites polished, the second with a nearly 

 straight transverse impression which is foveolate; the suture between 

 second and third tergites and the curved transverse furrow on the 

 third also foveolate; ovipositor sheaths about as long as the body. 

 Head, thorax, and abdomen of type uniformly testaceous; palpi pale 

 yellow; antennae black; legs entirely testaceous, except the apex of 

 hind tibiae and the hind tarsi, which are blackish; wings weakly 

 infumated. 



Male. — Essentially like the female; the anterior and middle tro- 

 chanters and the extreme base of their femora a little blackish; the 

 posterior tibiae mostly brownish black, 



Type.— Cat. No. 28687, U.S.N. M. 



Type locality. — Wild Horse Canyon, Animas Mountains, Arizona. 



Allotype locality. — Globe, Arizona. 



Described from one female and one male. The allotype was taken 

 on Thurheria thespesioides by C. H. T. Townsend. 



22. BASSUS NINANAE, new species 



Most similar to hicolor, but at once distinguished by the long, not 

 rounded, mostly smooth, dorsal face of propodeum; the thorax is a 

 little more slender and the pleura more conspicuously pilose than in 

 hicolor; furthermore, in the latter species the propodeum is rarely 

 red, and then the thorax is practically entirely red ; while in ninanae, 

 the propodeum is usually reddish, though the pleura and pectus are 

 black; the ovipositor sheaths are a little longer in ninanae, being as 

 long as the thorax and abdomen combined. 



Female. — Length, 6.2 mm. Face broader than long from anten- 

 nal foramina to apex of clypeus, rather densely pilose, malar space 

 fully as long as the second segment of antennal flagellum; temples 

 not broad, gradually receding; frontal impressions immargined; 

 ocell-ocular line not distinctly twice as long as the diameter of an 

 ocellus; antennae very slender, 36-segmented in the type; meso- 

 scutum rather long and narrow; the parapsidal furrows weakly indi- 

 cated, polished; furrow in front of scutellum with several distinctly 

 separated pits; propodeum mostly smooth, only slightly roughened 

 down the middle, not areolated, afid with a more or less distinct 

 apical transverse carina setting off the short, abruptly descending,
