According to 'Mr. Crotch, this is abundant in the spring 

 at Deal, and has hitherto been confounded with the immacu- 

 late form of A. plagiatus, Lin., but is of a deep black, with 

 no aeneous tendency, and has the metasternum sparingly punc- 

 tured and glabrous in the male. 



In addition to these characters on the under surface, 

 according to Erichson, it has the same metallic black colour, 

 the same lustre, shape and sculpture as A. plagmtuSfhnt is 

 always larger, with the head usually more thickly punctured, 

 the side of it projecting very little outwards, and the larger 

 punctures of the thorax proportionately smaller.

 Mr. Crotch has three specimens, which he inclines to think 

 are from the Lancashire coast. 



According to Erichson, this species is very like small spe- 

 cimens of A. prodromus, but readily distinguishable by the 

 lateral yellow spots on the head.

It is smaller than T. dermestoides, from which it may be
