a Family of Coleopterous Insects. 659 
This species (which is easily characterizable from the macu- 
lation of its elytra) varies upwards of a line in length: the 
smallest individual which I have seen is contained in the cabinet 
of the Linnean Society, and is somewhat darker-coloured than 
the larger specimens. 
In consequence of the priority in the nomenclature of this 
species employed by Donovan, I have considered it proper to 
retain his specific name for it. 
The dissections of the genus represented in the plate were 
made from a duplicate specimen of this species contained in 
the cabinet of the Linnean Society, in which the various parts 
figured are deposited. 
The peculiar form of the external incision of the base of the 
antenne is carefully represented in the plate.
