lobe feebly produced and broadly truncate in front of scutel- 
lum, surface coarsely, densely reticulate, with a few shallow, 
inconspicuous punctures intermixed. Scutellum triangular, 
nearly twice as wide as long, densely granulose, the granules 
flattened on top, resembling round, microscopic scales. 
Elytra slightly wider than base of pronotum, rather 
strongly convex, broadly depressed along lateral margins 
behind humeri ; humeral angles obtusely rounded ; sides par- 
allel and feebly sinuate from humeral angles to middle, then 
arcuately converging to the tips, which are conjointly 
broadly rounded, the lateral margins not distinctly serrate ; 
humeri strongly elevated; surface densely granulose and 
sparsely, coarsely punctate on the olivaceous-green and 
bright-blue areas, the granules similar to those on the scu- 
tellum, and sparsely, coarsely punctate on the shining piceous 
areas. 
Abdomen beneath densely, obsoletely reticulate, with a 
few inconspicuous punctures intermixed; last visible ster- 
nite broadly rounded at apex. Prosternum obsoletely reticu- 
late, with a few coarse punctures intermixed, the groove for 
the insertion of the antenna short and shallow. Metasternum 
shallowly emarginate in front. 
Length 2 mm., width 0.8 mm. 
Type locality . — Labeled “R. Froide, Port-au-Prince, 
Haiti.” 
Type . — In the Museum of Comparative Zoology, Cam- 
bridge, Mass. Type no. 23,700. 
Described from a single specimen collected at the type lo- 
cality October 3, 1934, by P. J. Darlington, Jr., to whom I 
take great pleasure in dedicating the species. 
This species differs from all the known species of Leio- 
pleura in having the peculiar scale-like sculpture on the 
elytra and scutellum. 
Micrasta piiertoricensis, new species 
Male . — Oblong oval, equally rounded in front and behind, 
moderately shining, glabrous ; uniformly black, with an in- 
distinct bronzy tinge above ; body beneath black, with a faint 
purplish reflection, the tarsi yellowish, with the tarsal lam- 
ellae whitish. 
Head feebly convex, when viewed from above forming a
