This species was originally described by Dr Bolivar from specimens obtained in Mahe 

 by M. Alluaud in 1892. A single $ and 2 $, obtained in Mahe and Praslin in 1905 by 

 Professor Stanley Gardiner, were considered by Dr Bolivar to be a new species, which he 

 called in his MS. C. hicornutus. His description of this proposed new species is as 

 follows : —

It will be seen from the above that Dr Bolivar thought that the ? previously 

 described as C. sechellensis should be referred to the proposed new species (C. hicornutus), 

 while the $ previously described as C. sechellensis should remain under that name : so
