longed backward, as a shallow impression, to a line between 
the foveze. These latter are circular, separated by a space 
three times as great as that intervening between each one and 
the eye, and are situated on a line passing from center to 
center of the eyes. Below and posterior to either eye is a strong 
spine. Pa/pi with the first joint gradually curved, increasing 
in thickness toward the third, which it exceeds three times 
in length. Third joint triangular, with the free angle produced 
into a spine; fourth triangular, free angles obtuse. Antenne 
‘with the first joint cylindrical, not so long as the width of the 
adjoining frontal tubercle; second to sixth oblong-subglobular, 
gradually shorter, the seventh small, globular, eighth as long 
as the third, drawn out on the inner side into a long, concavo- 
convex tooth reaching the base of the tenth joint. Ninth and 
tenth transverse, the latter three times as wide as the seventh, 
last joint wider than the tenth, ovoid, slightly truncate at base, 
and longer than the two preceding. Prethorax convex, widest 
at the middle, where the sides are strongly arcuate, but they 
become straight in front of and behind\the point. Neck half 
as wide as the greatest width, and not quite two-thirds that of 
the base. Disk punctulate, without anterior circular impress- 
ions, and with small basal fovez connected by a fine linear 
sulcus. /ytra depressed anteriorly, breadth at the shoulders 
a little less than the length of the suture, tip one-fourth wider. 
Disk punctulate, shoulders prominent, subangulate, sutural 
lines entire, parallel, suture depressed, discal lines sulciform, 
bottoms flat, reaching half-way to the tip. Abdomen convex, 
wider across the posterior margin of the first segment, which 
has no carinz, the posterior segments rapidly decreasing in 
width. Legs with anterior femora tri-spinous, joints two and 
three of the tarsi equal in length. 
Habitat. Same as for C. zzeg/ert.
