60 COLEOPTERA. 



transverse furrows of the abdomen, not so closely punc- 

 tured. 



Discovered by Mr. D. Sharp in the early part of 1864, in 

 a ravine on Wimbledon Common, the bottom of which was 

 very wet, and overgrown with Sphagnum : subsequently 

 taken at the same place by myself, Dr. Power, Messrs. 

 C. and F. Waterhouse, Smith, Janson and others.

About the size of O. depressus, Grav., and of some- 

 what similar appearance, but differing from that species as 

 follows: — the basal joints of the antennae are stouter; the 

 head is not so dull, and has two polished elevations at the 

 base of the antennse, the space between which, including the 

 clypeus, is more or less polished ; there is also a small longi- 

 tudinal fovea at the base of the vertex. The thorax is not 

 quite so deep, with a more decided dorsal channel (the ele- 

 vated lines on each side of which are bright, as also are the 

 outer parallel lines), and the depressions on the sides more 

 conspicuous. The elytra are lighter in colour, and not so 

 dull, being very delicately and closely strigose longitudinally 

 (in fact, almost alutaceous), with a few scattered and faint 

 punctures; they are moreover pitchy-brown, with the sutural 

 space somewhat broadly rufo-testaceous and shining. The 

 abdomen is shining black, finely alutaceous. The legs are 

 entirely pale testaceous. 



The male is rather brighter than the female, with the 

 antennas (especially the apical joint) stouter ; the sixth seg- 

 ment of the abdomen beneath is produced in the middle of 

 the hinder margin into a slight triangular point, behind 

 which is a semi-circular ridge, the two points whereof are 

 sli<^htly reflexed near the apical margin.
