CHCEEADODIS. — MANTINJ2. 127 



Hab. Guatemala, Panima in Vera Paz (Champion) ; Nicaeagua, Chontales (Jansori) ; 

 Costa Rica, Cache (Rogers) ; Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 



This species is very closely allied to C. rhombicollis, Latr. It has the pronotum (?) 

 similarly shaped ; but the elytra are not quite so wide, with the costal field narrower and 

 the costal margin less arcuated beyond the middle. The black marking on the anterior 

 femora is placed beyond the unguicular sulcus and distant from the base; while in 

 C. rhombicollis this marking is placed before the sulcus and extends towards the base. 



In the shape of the pronotum C. servillei agrees exactly with the figures of C. rhombi- 

 collis given by Westwood and Wood-Mason. Wood-Mason's figure of the pronotum 

 of C. servillei (?) is too much rounded, not sufficiently pentagonal, and not narrowed 

 enough posteriorly, with the anterior margin rather too oblique.
