Differs from all the other species (which are bronze or greenish black) by 

 being quite black ------ globosus 



These species all frequent sandy places, especially sea-shores, where they 

 prey upon minute Brachelytra; and they can be frequently found by the 

 tracks of the burrows they (or perhaps rather their prey) make in the sand. 

 Most of the species are local, the commonest being probably thoracicus, 

 salinus, and globosus.
