10 NEW VORK STATE MUSEUM 



midges have been reared from various food plants and described. 

 The outbreak by the Hessian fly, noted above, and an abundance 

 of the pear midge in the vicinity of Albany afforded opportunity 

 for additional studies of two economic forms. 



Lectures. The Entomologist, as in past years, has delivered 

 a number of lectures upon insects, mostly economic forms, before 

 various agricultural and horticultural gatherings. This work en- 

 ables him to become personally acquainted with the problems of 

 various localities and has been greatly facilitated by a chart show- 

 ing the results secured in codling moth experiments of recent years. 



Publications. A number of brief, popular accounts of the more 

 injurious species of the year were widely circulated through the 

 agricultural and local press. The important publications, aside from 

 the report for last year, are : The Elm Leaf Beetle and the White 

 Marked Tussock Moth (Museum Bulletin 156), Control of Insect 

 Pests in Institutions, The Identity of the Better Knoz^'ii Midge 

 Galls, The Fundamentals of Spraying^ and several papers describ- 

 ing new species of gall midges. A list of the more important pub- 

 lications is given on a subsequent page. 



Collections. There have been material additions to the collec- 

 tions through the efforts of members of the office staff, and also 

 by exchange and donation. Through the courtesy of Dr Otto 

 Niisslin of Karlsruhe, Germany, we received an excellent series of 

 European bark beetles. Mr Henry Bird of Rye, generously donated 

 an admirable lot of reared stem borers belonging to Hydroecia or 

 closely allied genera, a number of these forms being almost un- 

 represented outside Mr Bird's exceptionally fine collection. The 

 work of arranging and classifying the museum collections has con- 

 tinued whenever opportunity offered. Mr Young did considerable 

 miscellaneous work upon the beetles or Coleoptera, giving special 

 attention to the flea beetles, Halticini of the Chrysomelidae and to 

 the June beetles, Lachnosterna and its immediate allies of the 

 Scarabaeidae. An excellent series of genitalic mounts was made in 

 this latter group. 



The value of the collections has been greatly increased by micro- 

 scopic preparations. Specimens of the Scolytidae received from 

 Doctor Niisslin and noted above were put in balsam mounts. There 

 were, in addition, two hundred such preparations of gall midges, 

 mostly from reared material, and a number of scale insects, some 

 previously unrepresented in the collections, which were similarly 

 treated. The value of this material is much enhanced when placed
