Differs from laeviceps Ashmead in having the body lighter col- 

 ored and the wings shorter than the abdomen. 



Female. Length 2 mm. Head transverse-quadrate, broad and convex 

 behind the eyes, slightly wider than high as viewed from the front, excavated 

 behind, shagreened, except lower part of cheeks, middle of face just above 

 the insertion of the antennae, and a space just above each mandible, the for- 

 mer two areas polished, impunctate, the latter striate, the striae converging 

 toward the base of the mandible; lateral ocelli equidistant from eye-margin 

 and anterior ocellus; occiput margined; cheeks immargined; clypeus trans- 

 versely linear, broadly and shallowly emarginate apically, the lateral angles 

 sharp, dentiform; mandibles large, strong, bidentate, the upper tooth the 

 longer; base of antennae partially covered by a curved plate; antennae 12- 

 jointed; scape slightly longer than the club and nearly as wide, not notice- 

 ably curved; pedicel conical, a little shorter than, but just as wide as the 

 first funicle joint, less than twice as long as wide at its apex; first funicle 

 joint as long as joints two and three united, of the same width as the second; 

 second funicle joint as long as the next two united, globose, a little longer 

 than wide; third and fourth funicle joints small, transverse, subequal in 

 length and width; club cylindrical, composed of six joints, the first subtri- 

 angular and transverse ; second a little wider ; third twice as wide as long and 

 a little longer than the second; fourth of the same length and width as second; 

 fifth as long as third but a little narrower; sixth slightly the longest, obconical, 

 rounded apically; thorax obovate, rounded in front, at the tegulae as wide 

 as the head; mesonotum shagreened; notuli distinct only basally; anterior 

 half of episternum, sternum, and posterior border of pronotum strongly 

 punctate; posterior half of episternum and epimeron polished and impunc- 

 tate; scutellum twice as wide as long, separated from the mesonotum by a 

 row of deep punctures and with a free apical edge separated off by a row of 

 punctures; postscutellum extending over the propodeum in the form of a 

 plate, three times as wide as long and one-third the length of the scutellum, 

 margined apically, with regular longitudinal striae placed about twice their 

 width apart; propodeum hollowed out, to receive the abdominal horn, the 

 lateral edges sharp, forming a shelf over the rest of the propodeum; lateral 

 face with a smooth, impunctate area; area just above hind coxae rugose; 

 abdomen longer than head and thorax united, broad, spatulate, but rather 

 sharply pointed apically; first tergite longer than wide, striato-punctate, the 

 horn as high as the postscutellum when the abdomen is extended; second 

 tergite about as long as the first, strongly longitudinally striate, its sides 

 oblique, the apical edge one-third longer than the anterior; third tergite 

 slightly wider than long, distinctly longer than the second, its sides parallel, 

 shagreened subapically and sublaterally, and covered sparsely with white 

 hairs, the rest of the surface smooth, impunctate; fourth tergite two and 

 one-half times as wide as long, nearly as long as the two following, sparsely 

 punctate, and covered with long white hairs as are also the two following
