This species is intermediate between Xantholinus chloropterus 

 and X. cyanopterus. From the former it may be distinguished, 

 apart from its smaller size and different colour, by having tlie 

 prothorax more narrowed behind, and the punctuation of the 

 elytra comparatively stronger ; and from the latter by the shape 

 of the head and prothorax, which are elongate and nearly parallel- 

 sided, as well as in colour. From X. chalcopterus it differs in 

 having black legs.
