4 GEOLOGICAL SURVEY OF NEW JERSEY. 



barrens was therefore covered, but not nearly as thoroughly as desira- 

 ble. Unfortunately these gentlemen were all collectors of Coleoptera or 

 of Lepidoptera, and in Lepidoptera of only small portions of the order. 

 So far as the fauna of the pine barrens is concerned, we know absolutely 

 nothing of it save in Coleoptera and Lepidoptera. In Newark and its 

 immediate vicinity are a number of collectors who have formed an Ento- 

 mological Society, which holds semi-monthly meetings. This society 

 and its members have furnished me valuable lists giving the collective 

 experiences of its members. These lists are cited in the following 

 pages as the " Newark List," and the species are generally taken not 

 many miles from the city of Newark. As this includes territory from 

 salt marshes to mountain, further specialization in future lists will be 

 desirable. As in Philadelphia, all the collectors confine themselves 

 to Coleoptera or Lepidoptera, and in Lepidoptera none collect the 

 micros, so called. The only collector who has a general collection of 

 any size is Mr. M. S. Crane, of Caldwell, and from him I had lists in 

 Hymenoptera, Hemiptera, Diptera, Orthoptera, Neuroptera, Coleoptera 

 and Lepidoptera, which proved of the greatest assistance to me. In 

 the cities of New York and Brooklyn there are a considerable number 

 of entomologists and collectors who do a great deal of their collecting 

 in New Jersey, and some of these have added materially to the com- 

 pleteness of the present list. As usual, these gentlemen confine them- 

 selves to Coleoptera and Lepidoptera. Had the time been less press- 

 ing I could probably have gotten further aid from these gentlemen, 

 but the collecting season and immediately after are bad times to expect 

 aid from entomologists. It will be noticed that, except in Coleoptera 

 and Lepidoptera, New Jersey is practically unexplored, and even in 

 the collected orders, northern and northwestern New Jersey are entirely 

 unrepresented. These facts must be my excuse for any incomplete- 

 ness in the list. So far as my own collections are concerned. I must 

 say that I lived in the city of Brooklyn during the period of my most 

 enthusiastic collecting days and that many a pleasant day was passed 

 in the hills back of Montclair, in the woods near Fort Lee, or in early 

 spring along the foot of the Palisades from Hoboken to Weehawken 

 and further north. I have also spent many pleasant days on Dr. 

 Brakeley's plantations in Ocean county and have taken many good 

 species there. As I collected in all orders, I have been able to add 

 considerable to all lists, from my own experience. 



To specialize : In the Hymenoptera I have used Mr. E. T. Cres-
