(inch Holotype). 
Description.—Trunk compact, its greatest width, across second pair of lateral 
processes, more than two-thirds of its length ; lateral processes separated by much less 
than their own diameter; intersegmental suture-lines well-marked. Ocular tubercle 
rather bluntly conical, broader than in C. rohusta, occupying greater part of width of 
cephalon ; eyes dark, sharply defined, anterior pair the larger. Tubercles near anterior 
border of cephalon less distinct and more laterally placed than in C. rohusta.

Proboscis hardly decurved, distinctly longer than trunk, less narrowed at base 
than in C. rohusta, with proximal dilatation less abrupt and the widest part hardly 
beyond middle. 
Abdomen distinctly clavate, longer than maximum diameter of proboscis. 
Palp not differing greatly from that of C. rohusta except that the terminal 
segment is much shorter than the preceding ; distal segments minutely spinose. 
Ovitjer resembling that of C. rohusta ; spines of distal segments (much worn in
