 able to compare his specimen with mine, to determine their specific 

 identity." J. C. Dale, Esq. No other British locality has hither- 

 to been discovered, as far as we know.

This species is certainly pretty closely allied to C. macrocephala, 

 but it appears sufficiently distinct. Little notice seems to have
