Fig. 29 
Pale reddish brown, in part paler or darker: 
head reddish brown; antenna pale ochraceous; 
prothorax reddish brown, a pitchy stripe 
along each side of disc, elytron pale reddish 
brown, with some small irregular darker 
brown marks; ventral surfaces pale reddish 
brown, nearly testaceous on abdomen; legs 
testaceous, pitchy before femoral apices, and 
near tibial bases and apices. Dorsum some- 
what unevenly clothed with minute buffy 
scale-hairs and with scattered erect hairs, par- 
ticularly on posterior half of elytron. 
Head five-sixths as broad as prothorax, 
slightly broader than deep, distinctly and not 
very closely punctured on frontoclypeus; oc- 
ciput finely and sparsely punctured, feebly 
carinate medially behind an anterior depres- 
sion. Antenna three-fourths as long as body, 
fairly slender; scape stout, nearly twice as long 
as second segment; third to sixth slender; 
fourth distinctly longer than third, and a little 
longer than sixth; last longest. Prothorax four- 
fifths as long as broad, seven-tenths as broad 
as elytra, somewhat evenly rounded at side, 
nearly as broad at apex as at base; disc slightly 
uneven, with a low swelling at each side just 
anterior to center, finely punctured, with 
roughly 20 punctures in an approximate me- 
dian row. Scutellum "U”-shaped, slightly 
broadened at base. Elytron more than twice 
as long as prothorax, suboblong, narrowed 
apically; disc with eight regular puncture-

rows above, with an extra scutellar row, and

spaces longitudinally, but much narrower 
than interstices transversely. Ventral surfaces 
feebly and irregularly punctured. Legs long; 
hind femur exceeding elytral apex. Length
