Bulletin No. 14 of the Oregon Station.*—In this bulletin, which is prelimi- 
nary in its character, Prof. Washburn introduces the subject by a “A 
Plain Talk About Insects,” in which he gives some idea about trans- 
formations and classification of insects, tabulates the injurious species 
of 1891, and treats briefly the Grain Weevil (Silvanus surinamensis), a 
sugar-beet beetle (Monoxia guttulata), and the Tent Caterpillar (Clisio- 
campa spp.). He quotes an actual experience in the use of bisulphide 
of carbon against the Grain Weevil, showing that 2 quarts, when used 
in each of two bins 20 by 20 féet, gave excellent results, the total cost 
for treating 3,000 bushels of wheat being $3. The sugar-beet beetle is 
one of the Leaf-beetles, and has been commonly destructive to Sugar 
Beets raised in Oregon. They were successfully destroyed by the use 
of Paris green in the proportion of 1 pound to 100 gallons of water, 6 
pounds of whale oil soap being added to this amount of the poison, 
presumably in order to fix the mixture to the leaves. 
Entomology at the Leland Stanford, jr., University.—Prof. J. H. Comstock, 
of Cornell University, has been engaged by President Jordan to de- 
liver a course of lectures at the Leland Stanford, jr., University, com- 
mencing January 4, 1892, and extending over a term of three months. 
We understand that it is to be an annual arrangement, and that Pro- 
fessor Comstock will spend his winter vacation in California in this work 
in the future. 
New Edition of Bulletin No. 6, Division of Entomology.—Owing to the fact 
that the first edition of Bulletin No. 6 of this Division, which treats of 
the Imported Elm Leaf-beetle, was exhausted some years ago, and to 
the further fact that there is still a constant demand for information 
concerning this important elm pest, a new edition has been published 
which will be sent on application. The old bulietin is reprinted and an 
appendix is added which discusses the question of the number of annual 
generations, and gives the result of some additional experience in the 
matter of remedies. 
Popular Lectures on Insects.—Beginning December 28, 1891, and con- 
tinuing twice a week until January 21, 1892, the entomologist delivered 
a series of popular lectures before the Lowell Institute in Boston, Mass. 
The following topics were treated: I, Scope and importance of Ento- 
mology: II, Means of dealing with our insect foes; insecticides and in- 
secticide appliances: III, Some insect foes to cultivated plants and 
domestic animals: IV, Little known facts about well known household
