near the tip, the exterior one originates at the 

 humerus, and the other takes its rise on the 

 basal margin, midway between the exterior vitta 

 and the scutel, it does not approach the suture 

 at its tip; sutural edge black; the series of 

 punctures are rather large and profoundly im- 

 pressed: beneath black, punctured: feet pale 

 testaceous. 



OBSERVATIONS. 



This is the C. bivittatus of Melsheimer's 

 Catalogue; I certainly would have adopted his 

 name, had I not inadvertently pre-occupied it 

 with the description of the preceding species, 

 before I was acquainted with this insect. It 

 can be readily perceived to be specifically dis- 

 tinct from either of those represented with it 

 on the accompanying plate, by the confluent 

 density of the thoracic punctures, as well as by 

 its colours and their arrangement.
