Troglosternus ecitonis sp. nov. 
Length 2.75 mm. 
Form broadly oval, convex above; rufo-piceous, ventral 
surface and appendages lighter; thorax and legs shining, elytra 
subopaque. 
Head between eyes rather strongly and broadly concave, 
sides coarsely bimarginate, the inner margins short, the outer 
convergent at middle, then divergent, forming an hour-glass 
outline and extending to clypeus, front with four separated 
foveolate punctures. Clypeus nearly flat, shining and smooth, 
except for a series of four very coarse punctures near anterior 
border, which is truncate; front coarsely punctate. 
Pronotum transverse, broadest behind, anterior corners 
obtusely angulate, sides moderately arcuate, anterior border 
concave, posterior border broadly rounded, median portion of 
surface convex, basal portion near border with a pair of small 
deep pits; side portions obtusely gibbous a little behind middle, 
with three strong costae, the inner of whic&i is angulately bent 
near apex of gibbosity, the middle subparallel to the inner, but 
less sharply bent and the outer one finer, intercepted, and ex- 
tending forward as a submarginal line to the anterior border; 
median portion with coarse, widely separated setigerous punc- 
tures and sparse very distinct though fine shining reticulate 
costae, surface between punctures smooth and shining; gibbous 
portions of sides smooth between costae and lateral surface, between 
marginal and second costae longitudinally impressed and with a 
row of coarse punctures. Elytra finely, densely striate longi- 
tudinally, some of the striae on the basal portion bifurcate; disc 
with four coarser striae, conspicuous at basal third, then as fine 
as and continuing with the other dorsal striae, humeral stria 
strongly arcuate and coarser than the three others. Propygium 
and upper half of pygidium rugose-punctate and reticulately 
striolate, lower half of pygidium with very sparse coarse punc- 
tures. 
Prosternum broad, nearly flat, margined at sides with sharply 
impressed submarginal lines that extend on posterior half and 
are connected by a transverse line, enclosing with the posterior
