CATALOGUE OF INSECTS FOUND IN NEW 



JERSEY. 



BY JOHN B. SMITH. 



INTRODUCTION. 



Any faunal list making pretense to completeness, must be based 

 upon years of careful collecting and observation, not by one, but by 

 many individuals. In my work of compiling the present list I have 

 been hampered in every possible direction, and incompleteness of the 

 work will, I hope, be not entirely charged as incompetence in the 

 compiler. The labor on material for the list has been confined to the 

 few spare hours I could gather from a summer's active field-work, 

 and to about three weeks' work in compiling the results obtained from 

 my correspondents. New Jersey offers quite distinct contrasts in her 

 geological features, and, as this influences the botany to a very large 

 extent, it necessarily also affects the character of the insect fauna. 

 There are no large general collections of insects in the State, and 

 records of this kind were shut off. Collectors of insects are few, and 

 are massed in two or three localities, hence many parts of the State 

 are entirely unexplored, and the contrasts between the fauna of the 

 sandy pine-barren region and of the rocky Orange mountain district 

 are not well brought out. Collectors lacking, little material has come 

 into the hands of the systematists, and hence there are few references 

 in the literature to New Jersey as the home of species. Pennsylvania 

 and New York are constantly referred to. New Jersey seldom. The 

 material for a list of insects was therefore not to be sought in litera- 

 ture. In Philadelphia there are a number of active collectors who do 

 a large part of their collecting in this State. From some of these I 

 have obtained most valuable lists of captures. The excursions made 

 by these gentlemen were generally confined to the Camden and Glou- 

 cester county region, or extended to the sea-shore — a part of the pine
