scarcely visible ; lower surface more finely punctate than in robustus.

This species has been compared with robustus merely because 
of the superficial resemblance of the two. As a matter of fact 
the two species do not belong to the same group. The coarse 
punctation of the vittae and the finer punctation of the elytra 
alone would distinguish them even without the peculiar tarsal 
structure, which is similar to incongruus. 
Sphenophorus pontederise, new species. 
Form similar to venatus, about one-third as wide as long, general color 
dull black without alutaceous coating. 
Rostrum four-fifths the length of the thorax, slender, nearly perfectly 
cylindrical, moderately dilated at base, a little more above the scrobes, 
dilated portion rounded, moderately rather narrowly canaliculate, inter- 
ocular puncture rounded, usually deep; surface somewhat sparsely and 
finely punctulate except basal portion. Head sparsely punctulate, nearly 
smooth. 
Thorax longer than wide, moderately arcuate, gradually narrower to the 
apex, apical constriction not strong; disc densely coarsely and very deeply 
punctate, the punctures frequently confluent. Vittae broad shining, 
feebly elevated, and finely sparsely punctate; median vitta bifurcate in- 
closing an apical fossa and extending in a faint line through fossa but not 
attaining the base of the thorax, broadly dilated at and in front of the mid- 
dle; lateral vittae extending from the forked portion of the median vitta 
with which they are confluent and curving around the expanded portion 
of the median vitta to basal margin of thorax, being partially interrupted 
at apical third. Scutellum polished, moderately concave. 
Elytral surface somewhat unequal, finely striate, striae moderately 
coarsely punctate, punctures gradually finer to apex; intervals nearly flat, 
distinctly or slightly alternating in width and scarcely in convexity, very 
finely uniseriately punctulate. Pygidium coarsely punctate, hairs golden 
yellow, comparatively long, particularly about the apex where they ex- 
tend beyond the lateral tufts. 
Lower surface coarsely and densely foveate-punctate, nearly uniform at 
sides and middle, punctures largest, becoming confluent on the metaster- 
num, also on last segment where they form a small fossa at apex; first and 
second abdominal segment divided by a faint sutural line. Legs long, 
finely sparsely punctate.
