E. CONFLUENS, Lec. Form slender, depressed, sides of the 
elytra and abdomen parallel; surface punctulate. Length 1.2 
tozr.5mm. Plate XI., Figs. 110 and 112. 
¢ Head broader than long, trapeziform, one-fourth shorter 
from the frontal margin to the base than the width across the 
very prominent tempora; base sinuate and shortly carinate in 
the middle, tempora acutely rounded; eyes not prominent, sides, 
from the tempora to supra-antennal tubercles, nearly straight, 
slightly sinuate; frontal margin straight, slightly produced in 
the middle, as wide as the head is long; disk very coarsely 
punctured, flat, the inter-ocular fovee very small, mutually as 
distant as either from the eye; the groovesare parallel, broadly 
arcuate in the transverse frontal portion, included space smooth 
or less deeply punctured, mandibles prominent. Antenne one- 
third longer than the head, third to eighth joints transversely 
moniliform; ninth and tenth gradually wider; eleventh ovate, 
truncate at the base, where it is slightly wider than the tenth 
and four times wider than the funicle, the length and width 
about equal. Prothorax narrower than the head, widest 
before the middle, as wide as long, sides rounded in the middle, 
straight and convergent toward the neck and base, slightly 
sinuate opposite the lateral foveze; base broadly arcuate; disk 
punctate with a deep oblong fovea before the middle, running 
out into a shallow, longitudinal sulcus, reaching into the tri- 
angular median fovea one-fourth from the base; lateral fovez 
large, deep, very faintly connected with the median ones. 
Elytra densely pubescent, faintly punctulate, as long as wide, 
sides nearly parallel; disk flat, sutural lines nearly straight, 
parallel, base trifoveate, discal lines deep near the base, not 
_ reaching the middle; shoulders prominent. Addomen longer 
than the elytra, the first and second dorsals carinate. The 
sexual differences are conspicuous, the head of the ¢ being 
shorter, the mandibles strong, prominent, the antenna more 
slender, and the abdomen shorter; the third ventral segment is 
bisinuate in-the middle behind, the fourth depressed at the 
middle of the base and covered by tufts of hair; the fifth has
