and sometimes base of head usually reddish orange, varying from yellow
orange to dark reddish brown; head, legs, and remaining ventral surface
black to reddish black. Dorsal surface ofbody glabrous, except for head
and lateral areas of elytra. Head with sides parallel from base to eyes;
surface densely punctured, sculptured as follows: median groove
flanked on each sideby 1 impressed groove; grooves extendingfrom area
near antennal insertions to above eyes; area between grooves elevated
into 2 divergent carinae. Rostrum about halfas longas head, constricted
at antennal insertions; apex expanded and inflated, nearly 1.7-1.8 times
wider than frons, with lateral angles lacking conspicuous blunt tooth;
submental area with 2 blunt teeth (male) or without teeth (female).
Antennae inserted dorsolaterally on basal third of rostrum. Pronotum
1.3 times wider than long, widest at base; sides weakly arcuate, strongly
converging to sinuate anterior margin; disc evenly convex, not
impressed; surface shining, smooth, with widely scattered minute
points. Elytra at base 1.2 times wider than pronotum; apex broadly
rounded; striae not impressed, with large, shallowly impressed, widely
separated punctures in nearly regular rows; interstriae smooth,

Comments. Adults of this species are easily recognized by the
glabrous reddish upper surface of the body. Nothing is known of the life
history or habits other than the species has been recorded on rolling
leaves of oak (Quercus species). In his unpublished dissertation,
