6Q COLEOPTERA. 



1| I'm. ; shining; black on the upper side, the thorax and 

 elytra margined with pitchy red ; the legs and underside 

 reddish-brown, and the antennae reddish-brown, with the 

 seventh and three apical joints pitchy. The elytra have the 

 stris composed of coarse and somewhat irregular double 

 rows of punctures, with the interstices strongly punctured. 



Taken at Rannoch, Perthshire, by Mr. D. Sharp and 

 Mr. Bishop in the early part of last autumn.

Mr. Waterhouse has detected an example of this species 

 in his own British Collection standing with O. sulcatus, as 

 which insect he believes it was given to him many years 'ago, 

 and has drawn our attention to the differences of the two 

 species, in the hope of obtaining further evidence of O. ex- 

 aratus being British. As yet it appears only known as an 

 inhabitant of South Europe. 



It differs from O. sulcatus as follows (amongst other 

 characters) : the two middle ridges of the thorax are sepa- 

 rated by a shallow groove instead of by a slender impressed 

 line ; the sides of the thorax are straighter, and its entire 

 surface is densely covered by very minute longitudinal 

 scratches, whereas in sulcatus it is moderately densely and 

 finely punctured. The elytra are rather less convex, and 

 have six costae on each, the first, third and fifth of which are 

 rather less raised than the others ; these alternate costJE being 

 wanting, or scarcely distinguishable, in O. sulcatus.
