IO NEW YORK 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 Known 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 
Nusslin 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 Nusslin 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
