the lateral tubercle is much larger and more conical. The 

 antennse are more slender, but the proportions of the joints are 

 very similar. 



Mr. Lewis did not meet with this species.

Distinguished from Acm. collaris by its shorter and broader 

 form and much finer and scantier pubescence, as well as by its 

 colour. It agrees with Gebler's description of his P. minuta, 

 except in the scutellum — black and glabrous in A. criocerinus, 

 and " albo-tomentosum " in P. minuta. 



Mr. A. Adams obtained a species from the coast of Man- 

 churia considerably larger (4 lines) and rather more strongly 

 punctured, which can scarcely be separated from the present 

 one.
