16. BASSUS CRASSICORNIS, new species 



Most similar to atripes, but readily separated by the shorter anten- 

 nae, the coarsely areolated propodeum, the wrinkled first tergite, and 

 by the deeper red coloring of the thorax. 



Female. — Length, 8 mm. Face long, rostriform, broadly elevated 

 dowTi the middle; malar space about equal to the eye height; clypeus 

 long, nearly as long as the distance between the clypeal foveae, 

 strongly transversely convex; the third segment of labial palpi about 

 as long as the fourth; labrum large; frons polished, immargined; 

 ocell-ocular line not more than one and one-half times the diameter 

 of an ocellus; antennae 29-segmented in type, stout, tapering rather 

 strongly to the tip, and but little longer than the head and thorax 

 combined; the first flagellar segment longer than the scape, about 

 three times as long as broad; the 10 or 12 apical segments only very 

 little longer than broad; thorax stout, parapsidal furrows very weakly 

 indicated, the lobes not prominent; the hind angles of mesoscutum 

 produced into vertically compressed rounded lobes that are rather 

 prominent; prepectal carina strong; prepectus descending abruptly; 

 mesosternum scarcely longer than broad; mesopleural furrow broadly 

 impressed but not at all foveolate; propodeum sloping gradually and 

 only slightly, rather regularly areolated, the elevated lines prominent; 

 propodeal spiracles short oval; metapleura smooth, rugose below; 

 inner spur of hind tibia a little longer than the outer but less than 

 half the basitarsus; apical segment of hind tarsi longer than the 

 third; second cubital cell triangular, petiolate; first abscissa of 

 mediella at least as long as the second; abdomen broadly sessile; first 

 tergite fully as broad at apex as long, longitudinally wTinkled, and with 

 two prominent dorsal longitudinal keels on the basal half; second ter- 

 gite longer than the third and with a more or less distinct curved trans- 

 verse impression, polished, the impression sometimes more or less 

 foveolate; ovipositor sheaths about as long as the body. Head, 

 including antennae and palpi, black; pro and meso pectus, tegulae, 

 and wing bases black; remainder of thorax deep red; all legs black, 

 immaculate; wings very deeply infumated; abdomen red.
