[September 
microsculpture; sides of elytra (8th intervals) dull, with 
almost granular microsculpture. Head 4/5 (.79 and .81) 
width prothorax but appearing wider; mandibles moder- 
ately long; eyes small but convex, scarcely more prominent 
than genae; genae slightly shorter than eyes, convex in 
l)rofile; 2 setae over each eye; frontal impressions parallel, 
not deep, irregular; mentum tooth bifid. Prothorax sub- 
cordate, about 15 or 14 wider than long (width/length 
1.20 and 1.27), widest about 1/3 from apex; base a little 
(about 1/10) narrower than apex; sides moderately arcuate 
anteriorly, then straight and converging posteriorly, then 
moderately sinuate before almost-right posterior angles; 
base scarcely emarginate at middle, slightly oblique at sides; 
apex very broadly and slightly emarginate, with anterior 
angles slightly advanced; lateral margins rather narrow 
anteriorly, very narrow posteriorly, each with a seta at 
basal angle and another about 1/3 from apex; baso-lateral 
impressions normal, sub-linear, somewhat wrinkled but not 
distinctly punctate; disc normal; basal area longitudinally, 
ii-regularly striate; base and apex not distinctly margined 
except near sides. Elytra suboval, narrowed anteriorly, 
a little more convex than usual in genus, 14 to 1/3 wider 
than prothorax; basal margin entire, almost rectangularly 
angulate and subdentate at humeri; sides broadly rounded; 
subapical sinuations almost absent; sutural angles nearly 
right but slightly blunted; striae fine, defined mostly by 
slope of intervals, rather finely punctate; intervals 1 to 7 
strongly convex, subcostate, almost equal in height except 
7th higher and costiform basally; 8th interval about same 
width but only slightly convex and very dull; 9th (sub- 
marginal) interval narrow and shining; each 3rd interval 
with 3 setigerous punctures spaced in posterior half (none 
anteriorly). Prosternal process and mesosternal declivity 
setose; sides of metasternum (not episterna) with a few 
coarse punctures but body below otherwise virtually im- 
punctate. Male with front tarsi not dilated and with no 
sexual pubescence; last ventral segment of male with 1 
strong setigerous puncture each side and several smaller 
ones in from margin near middle, of female with 2 seti- 
gerous punctures on one side and three on other. Length 
about 21 ; width about 6.7 mm.
