but sometimes a little spotted with greenish-bronze: body and legs brassy. 

 Female with two transverse carina; on the occiput, but no spine behind ; the 

 anterior edge of the thorax bituberculated in the middle. 



Not very abundant in the metropolitan district: I have occa- 

 sionally met with it on Hampsteacl-heath and near Hertford, in 

 May ; also near Gravesend. " More frequent a little inland (near 

 Swansea) than on the sea shore." — L. W. Dillwyn, Esq. " South-

Brassy-black, slightly pubescent ; clypeus in the male rounded in front, and 

 obscurely emarginate in the centre, its margins reflexed, the disc nearly 

 smooth, with an obsolete carina on the vertex, and a distinct elevated one 

 behind, terminating in an elongate slightly nutant horn; thorax finely 

 granulated, excavated in front, with two tubercles towards the middle, and 

 two others on the lateral margins; the anterior angles slightly reflexed; 

 elytra behind more or less reticulated with bronzed black. Female with two 

 arcuated elevated carina? on the clypeus, the thorax not excavated anteriorly. 



Known from the following by its deeper hue and the reticulated elytra, as also 

 by its more glabrous aspect and larger size. 



This insect occurs chiefly in maritime districts, though it does 

 appear inland. " Not uncommon in the meadows between 

 Gravesend and Cliffe." — Mr. Bainbridge. " Not uncommon in
