0. viridicollis ( ? ), Fahr., loc. cit., p. 315. 



Black with the elytra and legs brick-red, moderately shining and 

 briefly pubescent ; genso straight, clypeus semicircular,' deeply 

 emarginate in the centre, and with the angles of the emargination 

 moderately blunt ; the edge of the clypeus is slightly recurved, the 

 frontal carina is very slight, and the surface is slightly punctate ; 

 prothorax moderately convex in the anterior part, deeply but 

 moderately closely punctured, ampliate laterally, marginate all 

 round, the median and part of the base is rounded ; elytra 

 slightly elongate, but ampliate laterally past the shoulders, they 

 are finely geminato- striate, the intervals are covered with fine 

 setigerous punctures ; the humeral callus is not very noticeable, 

 and the second interval is hardly broader than the third ; 

 pygidium closely pitted ; metasternum normal ; inner part of 

 anterior tibiae non-spinose. 



Male : Frontal carina hardly distinct ; in the centre of the vertex 

 there is a very short, conical, tuberculiform tooth, and the anterior 

 part of the prothorax is slightly sloping but convex, and is not 

 impressed. 



Female : Similar to the male, but wath the head simple. 

 Fahroeus' type of 0. viridicollis is more greenish on the prothorax, 

 but is undoubtedly the female of hrevicoriiis .
