Extremely like //. Icevigatus, but much smaller ; the thorax 

 relatively rather larger, the punctuation rather stronger ; the co- 

 louring (including that of the pubescence) darker ; the legs and 

 antennae pitchy. The thorax is often rufescent at the anterior 

 angles ; the markings on the elytra like those of H. Icevigatus. 



Length \\ lin. 



My specimens, and some others which I have seen, are from the 

 Fens of Whittlesea. 



I am inclined to believe this may be a diminutive race of H. 

 Icevigatus.

A minute species (1| line in length), relatively much narrower 

 than H. Icevigatus, more linear, and with the thorax larger. The 

 thorax is rather broader than the elytra, and has the sides boldly 

 rounded in the female, and in the male is distinctly broader. 

 The general colour of the insect is pitchy black ; the sides of the 

 thorax, and frequently a middle longitudinal mark, rufescent. 

 The markings on the elytra are also rufescent, rather broad, and 

 not well defined ; they consist of a patch at the shoulder, an ob- 

 long discoidal patch on the basal third of the elytron, a transverse 

 band below the shoulder ; a curved band, with the convex side 

 forwards, below the middle of the elytra, and a sub-apical spot ; 

 the outer margin of the elytron is also pale, but interrupted imme- 

 diately behind the pale colouring at the shoulder. The pubescence 

 with which the insect is clothed is short and ash-coloured. 



Represented by eight specimens in Mr. Stephens' Collection ; 

 they were received from the Rev. F, W. Hope, who discovered 

 the insect in North Wales ; my own specimens are also, some of
