The single example, taken bj Mr. Melliss, from which the 

 above diagnosis is compiled has been carefully examined by 

 Mr. Rye, who remarks that it is unknown to him, but might 

 nevertheless perhaps prove to be the European atratus of 

 Heer. Judging from the description, however, of that spe- 

 cies, it Avould appear to be not only smaller and blacker than 

 the atratus J and with darker limbs, but (as I imagine) to have 

 its head more sparingly punctui'ed, and the dorsal punctures 

 of its prothorax more numerous. In the absence of a type of 

 the atratus from which to form a more decided opinion, I feel 

 tliat it would be extremely unsafe to identify it Avith tlie St.- 

 Ilelena species, and I have consequently enunciated the latter 

 as above.
