C. terrestris Sc udder. 



General color, somewhat lighter brown than the above species, mottled with pale 

 brown spots which are inclined to form longitudinal rows; sometimes the pale median 

 line is present on the pronotum but not always. Legs light brown with the usual trans- 

 verse bands present, but not so distinct as in C. maculatus. 



This species resembles the former one very closely in color and structure, the chief 

 difference being the lower carina of hind femora armed with many minute teeth crowd- 

 ed together on distal half. The femur of female is also armed with very small teeth. 

 Hind tibia straight in both sexes. 



This insect appears to be .ess common than C. maculatus as it is reported from 

 only two localities and has only been taken in very small numbers. Its habitat is simil- 

 ar to the former species. Blatchley gives its general range as including the Northern 

 United States and Canada East of the Mississippi River.
