carinate in the males, subcarinate in the females. Head black, 
bearing a patch of light brownish scales on front. Antennae piceous, 
club elongate ovate and entirely pubescent. Prothorax black, 
broadly rounded at sides, narrowed and slightly constricted at apex; 
covered with elongate-oval scales, oriented toward apex and light 
brown, with exception of a small patch of white scales at base near 
midline and an elongate patch of white scales on each side; disk 
evenly but not closely punctate, interspaces shining; prosternum 
shallowly concave, antecoxal ridges distinct. 
Elytra black to piceous at base and along suture, rufous toward 
sides (on fourth to sixth intervals); covered with elongate-oval 
scales, light brown except for a few scattered white scales. Scales 
of underside of thorax and abdomen light gray, similar to elytral 
scales in shape and size. Iemora moderately clavate; rufous except 
for piceous bases; covered with light brown elongate-oval scales. 
Tibiae rufopiceous, covered with linear light brownish scales. Tarsi 
piceous, fourth segment extending well beyond the third; claws 
connate for a short distance beyond their base and slightly divergent. 
Median lobe of the male genitalia only slightly broadened toward 
apex; spiculum gastrale slender, curved, somewhat hooked at anterior 
end (figure 52). Arms of the spiculum ventrale of the female geni- 
talia forming a rather elongate U, curved inward toward each other 
near their middle; anterior end of the stem markedly expanded 
(figure 104).
