 L875. 



My specimen agrees perfectly with the figures by Schmidt, named by Eulenstein 

 "C. crebrecostatus Grev." This identification is false, as can be Been by comparing 

 with Greville's original figure and description. Greville recognizes the probability 

 <»f this species being identical with Johnston's C. marginatus, and he bo names ii in 

 In- illustration. The identity is a fact, but Johnston's name is inadmissible, having 

 been preempted by Ehrenberg 6 for a quite different species. I am not satisfied 

 with making tin- above species synonymous with C. imperialis Grev., as is done by 

 !>«• Toni.' Greville'e figure and description Bhow marked differences, especially in 

 the border. Bui whether Bynonymous or not, De Toni's -election of the name imper- 

 ialis i- wrong, as both the above name and that of Johnston hold priority. !>«• Tool
