 the ordinary punctures: thorax also glossy and smooth, with a double row 

 of six impressions on the disc, and other punctures on the sides : elytra 

 ojMgue fuscous-hlack : legs dull testaceous : antennae with the base pitchy.

 within the metropolitan district, and also in Devonshire.

 tered punctures, and the disc with a double, somewhat waved, series of 

 larger impressions, eight in each: elytra brassy, slightly shining, jiubescent, 

 and punctulated : abdomen slightly pubescent : antennae longer than the 

 head, scarcely thickened at the apex, the terminal joints tomentose : mandi- 

 bles shorter than the head. 



Rare: I possess a single example, captured in the vicinity of 

 London; it has also occurred in Yorkshire, and, I believe, in 

 Suffolk.

 glabrous, punctulated, the disc longitudinally smooth, the smooth space 

 bordered on each side with a longitudinal series of about twelve distinct 

 punctures: scutellum ample: elytra very much punctulated, rather more 

 pubescent : abdomen narrow, linear, with the terminal ventral segment 

 notched at the apex : tarsi piceous : antennae filiform, black, pilosulous. 



I possess a specimen of this species, which appears to be scarce, 

 captured on the banks of the Thames, below Gravesend : it has 

 also been taken, but very rarely, " near Norwich.'"'— A^irS?/ MSS.
