REPORT OF THE STATE ENTOMOLOGIST 1904 361 



and describing the immature stages of over 40 species, 12 being 

 characterized as new. The assistant entomologist, D. B. Young, 

 has rendered valuable aid in the collecting, breeding and care of 

 ■specimens incident to this work. 



The office has fortunately been able to avail itself of the services 

 of Prof. Herbert Osborn of Ohio, a well known specialist on leaf 

 hoppers or Jassidae. He has done some special collecting in the 

 State and embodied his results in an annotated catalogue, listing 

 about 175 species, which is reproduced in our report. Mr E. P. 

 VanDuzee of Buffalo, a skilful entomologist and well known author- 

 ity on Hemiptera, has collected in the Adirondacks and Catskills, 

 and the value of his work is greatly enhanced by an annotated 

 •catalogue accompanying his collections, reproduced in our report. 

 His work has added over 1600 specimens representing over 300 

 species, six of which were previously unknown, to our collections. 



Publications. The principal publications of the entomologist, 

 to the number of 67, are listed under the usual head. The more 

 important of those issued during the year, are the following: 

 ■Grapevine Root Worm (Museum bulletin 72), Monograph of the 

 Genus Saperda (Museum bulletin 74) by the entomologist and 

 L. H. Joutel of New York, and the igth Report of the State Ento- 

 mologist (Museum bulletin 76). Mosqititos or Culicidae of New 

 York State (Museum bulletin 79) was practically completed during 

 the time covered by this report, but owing to delays of one kind 

 •or another it was not issued till the latter part of October. 



There is in press an important monographic account of the May 

 Flies and Midges of Nezv York, by Messrs Needham and Johannsen, 

 and the extensive quarto memoir on Park and Woodland Insects 

 is still unpublished. 



Collections of insects. Large additions have been made to the 

 state collections during the past season, particularly in the Culi- 

 ■cidae, which received special attention during the season of 1904. 

 We now have over 1800 pinned specimens of New York Culicidae 

 representing about 40 species, a goodly majority of the latter 

 having been reared from one or more isolated larvae, thus estab- 

 lishing beyond doubt the specific identity of the two stages. In 

 addition, the 108 specimens representing 63 species, received from 

 Prof. F. V. Theobald, a world-wide authority on Culicidae, brings 

 the total number of species in the collection up to 99, which is 

 increased slightly by the larvae of several others from which 

 adults have not been reared. The usefulness of this collection 

 has been greatly enhanced by the preparation of over 600 micro-
