Each season brings its own species to the front and species which are 

 taken in numbers one year may be missing the next ; in fact collecting 

 varies from week to week and day to day. However it is thought 

 that the records included in this paper represent about fifty per cent, 

 of the species likely to be found in such a situation. 



New Jersey is a portion of the x-Xtlantic Slope of the United States 

 and the boundary between the geographic and geologic provinces 

 known as the Coastal Plain and Appalachian province extends ob- 

 liquely across the state in nearly a straight line through Trenton and 

 New Brunswick. Three of the four major divisions of the Appala- 

 chian province enter New Jersey, these being the Appalachian 

 Valley, Appalachian Mountains and the Piedmont Plateau. In 

 New Jersey the Appalachian Mountains form a belt known as the 



Fig. I. Relief map of New Jersey showing geographic provinces (Dept. Cons, 

 and Develop. N. J.).
