Blacky shining : head obsoletely wrinkled^ with an impression on each side near 

 the eyes, between which and tJie latter are several elevated lines : thorax trans- 

 versely \\Tinkled, with a deep dorsal channel, and near the hinder angles on 

 each side two deep elongate impressions : elytra oblong ovate, deeply striated, 

 the striae impunctate ; no discoidal impressions, but a series on the margin 

 rather profound: body beneath very glossy black: claws and palpi ferru- 

 ginous. Female with the elytra rather obscure, the stria? more obsolete, and 

 the interstices flat. 



Not uncommon near London, particularly on Epplng-forest.

elytrisque wneis. (Long. corp. G lin.)

Black : head smooth : palpi ferruginous : thorax aeneous, shining, with a dorsal 

 channel, and two impressed lines at the base: elytra slightly striated, the 

 strife punctate, with two discoidal impressions, aeneous or coppery, shining :

 In the collection of J. H. Griesbach, Esq. and Is said to have been 

 taken In Cambridgeshire.
