Female . — Differs from the male in being uniformly pice- 
ous, with a more or less distinct cupreous reflection, and in 
having the last visible sternite more broadly subtruncate at 
apex. 
Length 2.75 mm., width 1.5 mm. 
Type locality . — Mt. Diego de Ocampo, at an altitude of

Type and allotype . — In the Museum of Comparative Zool- 
ogy, Cambridge, Mass. Type no. 23,699. Paratypes in the 
United States National Museum. 
Described from four specimens, two males and two fe- 
males (one male type), all collected at the type locality dur- 
ing July 1938 by P. J. Darlington, Jr. 
This species resembles Enbrachys otero Fisher, from 
which it differs in having the front of the head more shal- 
lowly depressed, the sides of the pronotum more strongly 
flattened, and in not having the gibbosities on the elytra so 
abruptly elevated. 
Leiopleura darlingtoni, new species 
Oblong, rather strongly convex above, broadly rounded 
in front, more strongly narrowed posteriorly; head yellow- 
ish cupreous ; pronotum reddish cupreous on convex median 
part, bronzy green on flattened area at sides ; scutellum 
bright blue ; elytra opaque olivaceous green, with a quadrate, 
opaque, blue spot behind the scutellum, a large, shining, 
piceous area on each side along lateral margin behind hu- 
merus, and a similar area in front of scutellum, common to 
both elytra; body beneath black, with a faint purplish re- 
flection, and strongly shining. 
Head strongly, uniformly convex, with four deep, round 
fovese behind the clypeus ; surface densely, coarsely reticu- 
late, with a few shallow, indistinct punctures intermixed ; 
antennae uniformly piceous, nearly contiguous at bases. 
Pronotum twice as wide as long, distinctly narrower at 
apex than at base, widest along basal half, strongly, uni- 
formly convex on antero-median part, strongly flattened 
along base and on each side along lateral margin; sides 
strongly, arcuately diverging from apical angles to middle, 
then parallel to the posterior angles; anterior margin sub- 
truncate ; base transversely sinuate on each side, the median
