Bulletin No. 14 of the Oregon Station. ' — In this bulletin, Avliich is prelimi- 

 nary in its cliarjU'ter. Prof. Washburn introduces tlir subject by a ''A 

 Plain Talk About Insects," in which he gives some idea about trans- 

 formations and classitication of inse(;ts, tabulates the injurious species 

 of 1891, and treats brietly the Grain Weevil {SilranKft ,si<nn<uiu'nsi.s), a 

 sugar-beet beetle (Mono.via <jiittiilat<(), and the Tent Caterpillar {CHaio- 

 campa spp.). He (piotes an actual experience iu the use of bisulphide 

 of carbou against the Grain Weevil, showing that 2 quarts, when used 

 in each of two bins 20 by liO feet, gave excellent results, the total (;ost 

 for treating 3,000 bushels of wheat l)eiug $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 pcmnd to 100 gallons of water, 6 

 pounds of whale oil soap being added to this amount of the poison, 

 presumably in order to iix 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, 1 892, 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. 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 bulletin is reprinted and an 

 appendix is added which discusses the ([uestion 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 we^ik until January 21, 1892, the entomologist delivered 

 a series of popular lectures before the Lowell Institute m 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 in.sect foes to cultivated pbints and 

 domestic animals: IV, Little known facts about well known household
