inflation, or concave plates, which act so as to produce a vacuum 

 and thus enable the insect to walk on the lower surface of objects 

 (Comstock)." These cushions are termed pulvilli, or onychii. 

 The pulvillus of the last joint very often projects so as to appear 

 between the tarsal claws; it is the pulvillus. When, as sometimes 

 is the case, the last tarsal joint has two pulvilli, one under each 

 claw, there may be between them a third piece of similar structure 

 the empodium. 



The first pair of legs is directed forwards, the other two pairs 

 backwards. The first pair of legs is sometimes aborted, in which 

 case the second pair is directed forwards. 



The true, or thoracic legs, may or may not exist in the larva. 

 When they do exist they are jointed. False, or abdominal legs, 

 are found both in larvae and images, and will be referred to in 

 treating of the abdomen. P. P. C.

ENTOMOLOGY AT LONGPORT, N. J. 



BY JOHN HAMILTON, M.D. 



Longport is on the southern end of the island on which Atlantic 

 City is situate, from which it is distant about six miles. This 

 part of the island is narrow, and the space between the ocean and 

 the bay is a succession of sandhills without any extensive salt 

 marshes. The sides of many of these dunes and intervening 

 depressions support an interesting flora, much of which is strictly 

 maritime, and blooms during this month, attracting several spe- 

 cies of Lepidoptera and many beautiful Hymenoptera. The 

 native species of Coleoptera are few in comparison with the num- 

 ber on Brigantine Beach, where there are extensive salt meadows, 

 and where I could have taken two hundred or more species with 

 no more labor than was expended in collecting the forty-seven at 

 Longport. The species not formerly taken at Brigantine, for 

 which see Smith's Catalogue of the Insects of New Jersey were 

 Cicindela marginata Fab. , which was somewhat abundant among 

 the sand-hills with repanda and hirticollis; two forms of Cercyon 

 occurring together in great numbers in and under decaying sea- 

 grass deposited on sandy places by the bay tide, one of which, 

 on comparison with Swedish specimens, seems to be C. littoralc 

 Gyll. , and the other apparently only differing by having the apex
