Female.—Length, 6.5 millimeters. Head a little over two- 
thirds as long as wide, flat above, its posterior margin acute, 
straight; head strongly excavated below the upper posterior 
margin, attached to the thorax at its ventral surface, wrinkled 
and with a rather deep longitudinal furrow below; frons sha- 
greened, with many wavy longitudinal wrinkles, and with a 
median carina; hind margin of eyes projecting beyond the head 
posteriorly; median carina not reaching the clypeus; clypeus 
granular, wider than long, bidentate at apex, the emargination 
arcuate; malar space two-thirds the length of the clypeus, lon- 
gitudinally striate; mandibles 4-dentate, the lower tooth the 
longest; maxillary palpi 5-jointed, brown; fifth joint hardly 
longer than the fourth, yellow, blunt apically; labial palpi 3- 
jointed, brown; first joint three times as long as wide, devoid of 
pubescence, as long as the second; second joint scarcely longer 
than wide, flattened, densely covered with long white hairs; 
third joint much longer, threadlike, nearly as long as the first 
two united, finely pubescent; scape more than twice as long 
as the pedicel; scape and pedicel united not quite three-fifths

row depression across its base, the depression divided medially 
by a narrow partition; propodeum irregularly reticulate, a 
condition similar to that found in Psilodryinus reticulatus sp. 
nov.; propodeum rounded apically, somewhat excavated behind, 
the excavation bordered on each side by a longitudinal ridge; 
abdomen as long as the thorax, somewhat flattened; the last 
two segments compressed, the seventh more strongly so than 
the sixth; segments 1 to 5 finely granular, opaque, sparsely 
pubescent; 6 shining, with a few large scattering punctures; 
segment 7 triangular seen from the side, rounded apically, like 
a knife edge seen from above, finely and closely pubescent and |
