Winged, convex, deep black, with sometimes a brassy tinge 

 on the elytra. Head with an elevated transverse fold or band in 

 front, behind which is a longitudinal impression in the middle 

 of the forehead and a rugged fovea on each side; palpi and 

 antennae rusty red. Thorax transverse, narrowed in front, sides 

 rather straight behind, posterior angles right angles, base as 

 broad as the elytra, disk much wrinkled all over, the dorsal line 

 crossed in front by a depressed space, on the sides of which 

 appear a few punctures and longitudinal striae, the base also 

 depressed and much punctured, the punctures extending partly 

 up the margins, the basal foveae very slight. Elytra broad, 

 parallel, very convex, coarsely punctate-striated ; underside of 

 the thorax in the middle, breast and sides of the abdomen 

 punctured ; femora black, tibiae and tarsi red. Length 6i lines. 



This species, the only one of the genus found in Britain, is 

 apparently local and uncommon. According to Stephens it 

 occurred " in plenty at Worthing, in August 1817, and at 

 Brighton the following year," "in profusion at Hastings in 

 September," " every autumn plentifully in the open corn-fields 

 about Cambridge." It has been found also at Walmer and 

 Richmond.
