158 MANDIBULATA. — COLEOPTERA. 



with lutescent down than the intermediate, and the lateral margins more 

 densely than the back : legs black, clothed with yellowish-ashy down : an- 

 tennw ferruginous, with a black club. 



Very rare in Britain : I possess a pair captured about thirty years 

 since in the Isle of Ely : the larva, which feeds on plants of the 

 genera Phellandrium and Sium, is said to be very injurious to cattle, 

 when they happen to swallow it with their food. " Brugh-marsh."

Local ; and, at times, very plentiful near London, especially on 

 the banks of the Thames, between Fulham and Barnes, in the 

 autumn. " Common in the fens about Ely, the larvse inhabiting 

 the hollow stems of the Sium latifolium." — Rev. L. Jenyns.

Cylindrie, black, powdered with yellowish: head rounded, finely punctured; 

 rostrum rather short, a little curved, somewhat coarsely punctured, with an 

 interrupted longitudinal channel : thorax rugose, the anterior margin some- 

 what smooth : elytra subcylindric, with a transverse impression at the base ;

I possess a pair of this rare species, one from the collection of 

 Mr. Marsham, the other taken in July, 1818, at Hickstead, in 

 Sussex. I have seen a third specimen in the collection of Mr. 

 Ingall, who informs me that it was captured in the neighbourhood 

 of Sydenham.
