 The structure of the labrum in this species renders it 

 somewhat intermediate between the aggregates A and A A 

 (in the tabulation), being visible as part of the outline of 

 the head if regarded from behind only a little obliquely, but 

 in\T.sible from further back. It differs from all the other 

 species (of AA), having the clypeus deeply emarginate, ex- 

 cept exrisus<, Blackb., by its very much iiner and closer punc- 

 turation. Compared with ejccisus it is smaller, with the pro- 

 notum considerably less closely (and the elytra considerably 

 more finely) punctulate. I believe the imique type to be a 

 male. The prothorax is not much but very distinctly nar- 

 rower than that of ^the next species, from which however it 

 differs widely by characters noted below.
