PLATE 21, FicuRreES 21, 21a 
Female.—Piceous-black, shining; 1.41 mm. long, 2.75 times as long 
as wide. 
Frons concave between eyes, probably with concavity finely, closely 
punctured, but surface normally completely hidden by dense, long, 
shining, yellow hairs, extending downward from above and sides nearly 
to the epistomal margin, peripheral margin indented and very finely 
and closely punctured. Eye rather large, with moderate facets, about 
one-third divided by a rather broad emargination. Antenna (fig. 21) 
with club about 1.5 as long as 5-segmented funicle; first suture notched 
at sides, partially septate, septum only feebly arcuate; second and 
third sutures indistinct, indicated only by incomplete rows of setae. 
Pronotum 1.14 times as long as wide, widest behind ; posterior border 
margined, weakly arcuate, sides very feebly arcuate, subparallel on 
posterior half, distinctly constricted in front of middle, moderately 
narrowly rounded in front, with four to six serrations, median pair 
slightly longer ; contour of disk as seen from sides nearly evenly convex, 
the summit therefore scarcely elevated and the posterior transverse 
impression nearly absent; anterior area with slightly irregular, con- 
centric rows of low asperities; posterior area shining, with moderately 
coarse, close, deep punctures, interstices distinctly, finely reticulate; 
median line of moderate width, slightly elevated; appearing glabrous, 
but with minute hairs. 
Elytra slightly wider than pronotum and 1.63 times as long, about 
1.72 times as long as wide, sides nearly straight and subparallel on 
anterior two-thirds, broadly rounded behind; surface piceous black, 
brightly shining; strial punctures in nearly regular rows, only the 
first row impressed; interspaces narrow, finely rugulose, almost en- 
tirely impunctate; vestiture consisting of minute hairs from strial 
punctures and a few slightly larger ones from interspaces. Declivity 
moderately arched, not truly sulcate, but with suture slightly elevated, 
first stria impressed, with punctures smaller than those on disk; second
