elongate, rather cylindrical, insect, with the elytra proportionately 

 longer, as compared with the thorax, than in any British example I 

 have seen. 



Trnchyphloeus nristatiis, (xyll., and T. olivieri, Bedel (=^s(iii(inm- 

 latus, 01.). — The characters depending on the bristles of the elytra, 

 which are often abraded, are not very satisfactory for se|)arating these 

 two species. I propose the following : — 



A. Scape of anteniife ncai-ly straight, gradually dilated to apex; eyes larger and 

 less prominent T. aristatus, Gyll. 



AA. Scape of antennse angled outwards about the middle, and rather strongly 

 dilated from the angle to apex ; eyes smaller and more prominent .. 



T. olivieri. Bedel {= squamulatus, Ol.). 



I am indebted to Captain Ueville for pointing out the difference 

 in the scape, which seems to have escaped notice previously. Mr. E. 

 W. Morse took both the above species last August in some numbers, 

 together with T. alternans, Gyll., and T. scahricuius^ Linn., on the 

 banks of the river Witham, below Boston, Lines., under cut herbage, 

 left in heaps to rot.
