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 

 antennae is carefully represented in the plate.
