724 STATE BOARD OF AGRICULTURE. 



Dietz, Dr. William G., Hazelton, Penna. Lepidoptera, and especially the 

 Tineoidea. Dr. Dietz has prepared the list in this super-family, and is 

 authority not only for the general arrangement, but for many of the 

 species that are listed. He has been good enough to determine whatever 

 material has been sent him by New Jersey collectors, and also named not 

 a few Tortricids and Pyralids. In the Coleoptera Dr. Dietz's papers in 

 the Rhynchophora have been followed in the groups treated by him. 



Dkn. or Dn. Dickerson, Edgar L., Newark. Is a student at Rutgers, and 

 has collected in Coleoptera and Lepidoptera for some years. His chief 

 collections were made at either Chester or in the vicinity of Newark. I 

 have seen most of his material and have determined some of it. 



Doll, Jacob, Brooklyn, N. Y. A collector and breeder of Lepidoptera who has 

 few equals in the skill with which he prepares his specimens. 



Ds. Davis, Wm. T., Staten Island.. One of the few really good general col- 

 lectors. He has made it an object to thoroughly explore the fauna of 

 Staten Island, and his material, so far as he has not felt competent to 

 work it up himself, has been identified by specialists, so the records may 

 be considered entirely reliable. He has also collected at Manchester, in 

 Ocean County, Newfoundland, in Morris County, and, to a less extent, 

 Spring Lake, Passaic County, and other localities. 



Dyar, Dr. Harrison G., Washington, D. C, in charge of the Lepidoptera in 

 the U. S. National Museum. Dr. Dyar has made a specialty of classifica- 

 tion based upon larval structures, and his general scheme is accepted in 

 this publication. He has supplied many notes on food plants of Lepidop- 

 tera and has also added much to the list of saw flies among the 

 Hymenoptera. In a few instances the facts with which his name are 

 associated were obtained from his published papers ; but as a rule they 

 are original notes made by Dr. Dyar for this work. 



Edw. Edwards, Henry, late of New York City. Was a Lepidopterist of 

 recognized authority and published a list of the descriptions of early 

 stages from which some of the references to food plants are taken. 



Fernald, Dr. C. H., Amherst, Mass., Professor of Entomology at the Agricul- 

 tural College. Is a special student in the Tortricoidea Pyralidoidea^ and 

 his published lists and revisions are made the basis for the present 

 enumeration. Dr. Fernald has kindly looked over and determined my 

 entire material in the super-families mentioned, and has also determined 

 many species for other collectors. 



Fitch, Asa. Late of Albany, N. Y. , and State Entomologist for many years ; 

 all records credited to him are from his published writings. 



Fox, William J., Philadelphia. Assistant Librarian in the Academy of Nat- 

 ural Sciences. Special student in the aculeate Hymenoptera. Mr. Fox 

 has collected largely in Camden and Gloucester Counties, and his records 

 in the Hymenoptera add very largely to the list. In addition, he has 

 determined much of the material collected by others, including myself, 

 and this has made possible the incorporation of many records that would 

 otherwise have been unavailable. Without Mr. Fox's assistance the 

 actual capture data in the Hymenoptera would have been scant indeed.
