 pygmceum, Grav. (nee Payk.). 



This species must come next after O. concinnum in our 

 lists. 



It appears to be somewhat like O. deplanatum, but less 

 pubescent, more strongly punctured, and with longer an- 

 tennae, kc. ; and from O. pygmceuin, Payk. (which it re- 

 sembles in colour), it seems to differ in its linear shape, and 

 by its thorax being slightly narrowed towards the base. It 

 is a line and a half in length, sub-depressed, rufo-testaceous, 

 with the head and scutellar region infuscate, the head, 

 thorax, and elytra thickly punctured, and the abdomen 

 (which is rather dilated at the apex) sparingly and most 

 delicately punctulated. 



Mr. Matthews remarks that this species may be known 

 from O. concinnum, by its being shorter, with a much smaller 

 and narrower thorax, and invariably paler in colour. 



Three specimens were taken during the summer of 1862, 

 in rotten wood near Gumley, Leicestershire, by Mr. 

 Matthews.

 This species, according to Kraatz (loc. cit.), is more nearly 

 allied to O. vile than to O. monilicorne, to which latter it 

 is likened by Erichson, and it seems to be capable of distinc- 

 tion from the former by its stronger punctuation. 



From Erichson's description it is one line in length, shining 

 black, the legs and first five joints of the antennae rufo- 

 testaceous, the antennae scarcely longer than the head and
