■ingi' This is probably the most w'idely distributed species of the 



^ genus ; it is found in every part of the United Kingdom, and is 

 tJjeiDi scattered throughout Europe. The specimens from North America 



very closely resemble our insect, but are scarcely identical ; they 

 have the abdomen more closely punctured ; Mr. Kirby considered 

 them the same ; the species is described by Say as H. parallelus ; 

 if distinct, the similarity is very striking.
