insects and, as a consequence, the editions of certain more popular 

 bulletins and reprints, some dating back a number of years, were 

 exhausted the past summer. These publications could hardly have 

 been placed to better advantage. 



Faunal studies. Investigations along these, lines have been con- 

 tinued and a manuscript list of the insects of the Adirondack region, 

 based mostly upon material in the state collections, is nearly ready 

 for publication. This list is a growing one, additions being con- 

 stantly made thereto in connection with other work carried on 

 within the limits of this faunal area, such, for example, as the study 

 of grasshoppers noted above. 



Another valuable addition to the natural history of the State of 

 New York is practically ready for the printer, namely "A Mono- 

 graphic Account of the Caddis Flies or Trichoptera," by Dr Cor- 

 nelius Betten. This work had its inception in the studies of aquatic 

 insects begun at the entomological field station, Saranac Inn, in 

 1 90 1, many of the results of which are published in Museum Bul- 

 letins 47, 68, 86 and 124. The Trichoptera are an important group 

 economically, since there are numerous species occurring in all kinds 

 of fresh waters throughout the State, some of them being exceed- 

 ingly abundant and consequently of great value as food for fish and 

 other aquatic life. 



Substantial progress on the Monograph of the Stone Flies or 

 Plecoptera has been made by Prof. James G. Needham. This is 

 another study begun at the entomological field station mentioned 

 above and will make an extensive addition to our knowledge of an 

 important and comparatively unknown group of aquatic insects. 

 These studies and those already published on aquatic forms com- 

 prise by far the most important additions to our knowledge of 

 American aquatic insects. 



The contributions this office has made to a natural history survey 

 of the State are worthy of mention in this connection. The scope 

 of these studies is indicated by the titles cited and the amount of 

 work involved is suggested by the approximately 3500 pages of 

 text with numerous illustrations devoted to the discussion of the 

 various groups. The more important titles, aside from the long 

 series of reports and bulletins treating of specially destructive forms, 

 are listed below. 



Entomological Contributions 1-4 by J. A. Lintner, appearing in 

 the 23d, 24th, 26th and 30th Museum Reports, respectively, contain 

 many and valuable additions to the knowledge of our local fauna. '
