 maxillary longer than the labial. Antennce more than three or four times as 

 long as the body in the males, as long again in the females, slender ; basal 

 joint slightly robust, subclavate ; second short; third rather longer than the 

 fourth 5 the remainder subequal in the females, but gradually increasing to 

 the end in the males, the terminal joint being longest, sometimes half an inch 

 in length, and very slender : thorax transverse, tuberculated, with an obtuse 

 spine on each side : elytra broad, depressed : legs moderate, robust : tibics

Varied with fuscous and cinereous : antennae three times as long as the body, 

 ferruginous, with the base black : intermediate tibiae compressed, with a small 

 tooth on their outer edge. 



This beautiful species has been several times found in the vicinity of London, 

 but it has most probably been imported from North America, where it is not 

 uncommon. ,
