0RTH0CILETE8 INSIGNIS, Aubk : A BEETLE NEW TO BRITAIN. 

 BY NORMAN H. JOY, M.E.C.S., F.E.S. 



When loolcing over my collection of Coleoptera a sliort time ago, 

 Capt. Deville suggested that OrtJioehsete^ msignis, Aiibe, ought to 

 occur iu Britain, as it is not uncommon on the coast of Brittany, and 

 on examining my sei'ies of 0. setiger, Beck, he pointed out that four 

 specimens from Cornwall were to be referred to the former species. 

 He has since kindly sent me a Continental example and tlie original 

 description of the species. 



0. insignis resembles 0. setiger in colour, except that the antennae 

 are somewhat darker. The general shape differs considerably ; the 

 thorax is rather longer and more parallel- sided ; and the sides of the 

 elytra are sub-parallel, lieing only contracted for the apical third. 

 In 0. setiger they are evenly rounded, the elytra being broadest 

 about the middle. Perhaps the most obvious distinction in fresh 

 specimens is in the structure of the scale-like bristles on the elytra.
