Color and markings abnost precisely the same as in C. terrestris, so 

 that imperfect and immature specimens are exceedingly difficult to 

 separate ; but the darker markings in this species are as a rule darker 

 and cover the surface to a greater extent, and when the mediodorsal 

 stripe is present it is often broader and extends upon the meso- and 

 metanotum ; on the other hand, the maculation of the abdomen with 

 luteous is usually more striking in the present species (partly from 

 the darkness of the ground) and forms sometimes a tolerably regular 

 pattern, consisting on each joint of an anterior mediodorsal triangular 

 spot, a central subdorsal oblique dash, and posterior spots farther from 

 the middle line. The antennas are from two to three times as long as 

 the l)0(ly, and slender except at extreme base, and the legs are 

 moderately long. Fore femora no stouter than the middle femora, a 

 little more than a fourth longer than the pronotum and much less than 

 half as long as the hind femora, the inner carina with a long subapical 

 spine and occasionally an additional one. Middle femora with 0-2 

 spines besides a rather long subapical spine on the front carina, and 

 on the hind carina an occasional small spine besides a long genicular 

 spine. Hind femora of about the length of the body, three and a half 

 times as long as broad, about two and a third times as long as the fore 

 femora, moderately stout at base, the distal fifth subequal, with no 

 raised points on the upper or inner surface, the outer carina with 

 about thirteen unequal coarse spines, the longest hardly half as long as 

 the tibial spurs {$)ov with minute distant inconspicuous spinules ( 9 )>
