The unique type of this remarkable species is a female, having 

 the fifth ventral evenl}' and circularly arcuate at apex. It can be 

 recognized at once by the rectangularly parallelogramic form of 

 the prothorax.

Oblong, rather stout and feebly convex, shining, black, the 

 elytra pale ochreo-flavate, with a large triangular sutural spot at 

 the base of piceous-black ; abdomen pale, gradually obscure to- 

 ward base; legs and oral organs very pale ochreous; antennae 

 dark piceo-rufous; pubescence moderateh' fine and sparse, rather 

 long, suberect on the el^'tra ; marginal ^cilia somewhat long. 

 Head three-fourths as wide as the prothorax, finely, sparsely 

 punctate, the impressions distinct and widely separated; epi- 

 storaa unusually long and narrow, flavate; labrum long, para- 

 bolic; mandibles long, pale, obscure at tip; e3'es modei*ate in size 

 and not prominent; antenna? distinctl}' longer than the pro- 

 thorax, somewhat slender, the tenth joint distinctly wider than 

 long, fifth dilated. Prothorax two-fifths wider than long, the 

 sides subparallel, evenly and ver^- feebly arcuate from base to 

 apex, onh' very slightly' more convergent anteriorly; angles 

 obtuse ; disk finel}' and sparsely' punctate. Elj-tra oblong, not 

 quite one-half longer than wide, neai-ly one-half wider than the 

 prothorax, dehiscent very near the apex, the latter ver^- broadly 

 and obtusely rounded ; sides straight and parallel ; humeri right, 

 rounded, distinctly exposed at base; punctures rather fine but 

 distinct and sparse. Abdomen finely, somewhat closely i)unctu- 

 late, finely and thinl3' pubescent, the legs rather long, slender. 

 Length 2.2-2.4 mm.; width 0.9-1.0 mm. 



California. Both of the specimens before me are females, the 

 fifth ventral being broadly and feebh' arcuate at apex and the 

 genital segment deeph' excavated in the middle. The second 

 specimen agrees with the first in its long mandibles and labrum, 

 but the gelatino-membranous epistoma is wide and distorted, 

 showing that but little reliance can be placed upon the form of 

 this part when it has this soft consistence. In these specimens 

 both the spurs of the anterior and middle tibiie are slender. 



I have before me a third female from another locality, simi- 

 larl3' colored but narrower, with the sides of the prothorax gradu-
