Long. 3| lin. 
Hah. Ecuador. 
Head rather longer than broad, subtrigonate; encarpse trigo- 
nate, separated by a longitudinal groove which runs upwards 
to the vertex ; carina raised, linear; clypeus finely rugose- 
punctate, clothed with adpressed griseous hairs ; palpi ovate. 
Antennje filiform; the second joint short, ovate, the third nearly 
twice the length of the second, three fourths the length of the 
fourth, the four outer joints obscure yellowish white. Thorax 
more than half as broad again as long ; sides rather broadly 
margined, diverging from the base to beyond the middle, 
converging at the apex, the anterior angle mucronate ; upper 
surface subopaque, finely but distinctly punctured ; hinder disk 
impressed with three rather large fovese, one on the basal 
margin, the others one on either side, just behind the middle of 
the thorax, the three conjointly forming a semicircular depres¬ 
sion. Elytra much broader than the thorax, dilated pos¬ 
teriorly, convex, subventricose, opaque, finely but distinctly 
punctured.

Head much longer than broad, wedge-shaped; front im¬ 
pressed just above the encarpse with a deep fovea; encarpse 
thickened; carina raised, linear. Antennse filiform, tapering 
towards the apex ; the second joint short, the third one half 
longer than the second, two thirds the length of the fourth, the 
basal joint (its extreme apex excepted) piceo-fulvous. Thorax 
about one half broader than long ; sides parallel from the base 
to beyond the middle, thence converging to the apex ; surface 
smooth, impunctate, faintly impressed on the middle disk with 
a transverse, slightly curved sulcation. Elytra much broader 
than the thorax, dilated posteriorly, ventricose, very minutely 
punctured, the puncturing entirely obsolete on the hinder disk. 
This species may be known from all its allies by the longer 
head and by the extremely fine punctuation of the elytra.
