ENTOMOLOGY AT BRIGANTINE BEACH, N. J., IN 



SEPTEMBER. 



BY JOHN HAMILTON, M. D., ALLEGHENY, PA. 



In the preceding volume of the Entomologist (vol. xvi., p. 186) an 

 account is given of some of the Coleoptera found in September on Brig- 

 antine Beach, N. ].; and having been there this season from the ist till 

 the 1 8th of the same month, I propose to give a further account of some 

 of the insects inhabiting that region. 



Cicindela dorsalis Say is found in great abundance on the shore 

 between the lines of high and low tide, keeping as close to the water as it 

 can get. If too closely pursued it frequently takes wing, alighting in the 

 surf and coming to the shore in the foam, from which it usually escapes 

 before it can be taken. It is sluggish in its movements, running about a 

 yard, then stopping, and so on alternately, and flying only when pursued, 

 and then for but short distances. More than two-thirds of the females 

 captured want either a part of an antenna or of a hind leg, these mutila- 

 tions occurring on the right side in a large majority. 



Cicitidela hirticoUis Say is likewise in as great abundance as the pre- 

 ceding, but does not mingle with it nor willingly pass the high tide line, 

 inhabiting bare depressed places on the sandy beach surrounded by hil- 

 locks of white sand, on which it delights to bask in the hottest sunshine. 

 It is a great lover of heat and light, and is sought for in vain except during 

 a few hours of the warmest and brightest days. It is very wary and 

 active, and by no means easily taken. 



Cicindela repanda Dej. also occurs plentifully in bare places sur- 

 rounded by grass, and on paths and roads where the ground is dark ; when 

 disturbed it rises and lights a short distance off in the short grass, where 

 it is easily taken before it can again arise. 



Though inhabiting contiguous territory, the habits of these three species 

 keep thera socially separate.
