236 NaTuRAL History BULLETIN. 
perceptible, frontal fovea rounded, occipital fovez in depres- 
sions which are not open towards the eyes and which leave 
between them a narrow ridge connecting the occiput (which 
is not elevated) with the anterior part of the vertex. Palpi 
with the second joint pedunculate, somewhat triangular at the 
thick end, the last two transversely ovate, the appendages 
three times as long and hooked at the free end. Aztenne of 
the male three-fourths the length of the body, joints nearly 
equal, cylindrical, twice as long as thick, scarcely larger 
towards the end, last joint as long as the three preceding, 
flattened on the inside. Females with joints 7, 8, 9, and 10 
transverse, short, last joint shorter, oblong oval. Prothorax 
wider than long, and as wide as the head is long; the basal 
median fovee reach the middle of the disk, the lateral ones 
are smaller, lateral sulcus or depression fully separating the 
margin which is strongly arcuate. /ytvra more convex than 
in Ct. consobrinus, the discal and sutural lines though deep 
nearest the base, leave the intervals not very convex. Addo- 
men convex, margin broad, the edges arcuate. Legs long. 
Habitat. Territory east of the Mississippi. Iowa. 
Cr. consoprinus, Lec. Usually uniformly dark piceous 
or with paler elytra, legs, and antenne, pubescence very 
dense giving a rather rough appearance. Length, 1.75 mm.

Ffead with the frontal incision reaching the oblong fovea, 
the occipital foveze are small, the depression continuous from 
side to side and very shallow causing the occiput not to appear 
elevated. Otherwise the same as in the preceding species. 
Prothorax as long as wide, the basal median fovea shorter, 
the lateral sulcus separating a narrow slightly arcuate margin. 
£lytra more depressed, flat, the linear impressions deeper and 
the shoulders more prominent than in C?. frceus. 
Habitat. Same territory as the preceding. 
CT. ZIMMERMANNI, Lec. Pale brown or testaceous, not 
densely pubescent. Length, 1.65 mm. .
