maturing, by just so much have their powers of resisting the action of frost been red need 

 and their liability to be injuriously affected by succeeding cold increased. Hence it is iu 

 the spring of the year that they suSer the most. A period of mild weather in early 

 spring, followed by a protracted one of cold and wet, even when the frost is not severej 

 may be, and often is the cause of death to myriads of them. This is one of nature's 

 method.s of reducing their numbers. Coleopterous insects are not so liable to be injuri- 

 ously affected by this cause, the reason for this is clearly and beautifully placed before ua 

 in Dr. Hamilton's paper. It is to be regretted that so little careful observation has been 

 given to this interesting subject. 



FOURTH ANNUAL MEETING OF THE ASSOCIATION OF ECONOMIC 



ENTOMOLOGISTS. 



The fourth annual meeting was held in the University building, Rochester, N.Y., 

 on Monday and Tuesday, August 15th and 16th. The President, Dr. J. A. Lintner, of 

 Albany, N.Y.. occupied the chair, and Prof, F. M. Webster, of Wooster, Ohio, filled the 

 office of Secretary. The following members were also present : — C. V. Riley and L. O, 

 Howard, Washington, D.O. ; D. S. Kellicott, Ohio ; John B. Smith, New Jersey ; E. B, 

 Southwick, New Yotk; H. E. Weed, Mississippi; M. V. Slingerland, New York; H. 

 Oshorn. Iowa; J. Fletcher and C.J. S. Bethune, Ontario; C. H. Perkins, Vermont ; 

 P. H. Rolfs, Florida ; S. A. Forbes, Illinois. 



Owing to the ill-health of the President, the annual address was delivered by the 

 Vice-President, Prof. Forbes, in which he treated especially of the work that has 

 recently been done on the contagious diseases of insects, and the satisfactory results that 

 have thus far been obtained. He also referred to the successful importation of several 

 insect parasites, and drew the attention of the meeting to the desirabiliiy and import- 

 ance of studying the aquatic insects of America and their relation to tish culture. This 

 able and highly interesting address was subsequently reported ujion by a special com-< 

 mittee who warmly commended it and urt^ed upon thn attention of Eionomic Entomo- 

 logists the recommendations in regard to " Aquatic Entomology " and its bearings upon 

 fish culture. 



Pi of. Kellicott read a paper upon " Hypoderus Columbte," a mite which is para- 

 sitic upon pigf^ODS. 



A paper liy Mr. C. H. Tyler Townsend was read on " The possible and actual in" 

 fluence of irrigation on insect injury in New Mexico," in which he showed tliat in that 

 region of the country irrigation may be made to exert a valuable influence as an adjunct 

 to the proper use of arsenites and kerosene. 



Prof Kklltcott read "Notes on .^geriadfe of Central Ohio, No. II.," which is pub- 

 lished in the Cunadicoi Eiilo»iolof//st, ^September 1892, p. 209. 



Prof. Smith said thit adults of the Squash Borer (J/, ceto) from last year's larvae- 

 were then flying on Long Island, and that all stages of the insect might be obtained in 

 the same field. The moths assemble in the evening on the upper sides of the leaves and 

 are collected in great numbers by the farmers. Messrs. Forbes, Slingerland and Smith 

 stated that in their experience the ^gerians were not attracted by electric light. 



A paper on "The Bean Weevil (BrucUus obsoletics) " was read by Mr. M. V. Slinoer- 

 LAND, in which he described the mode of ovipositing and gave a brief account of the life 

 history of the insect. He stated that bisulphide of carbon will destroy the insect in all 

 stages. He also read a paper on " Drasteria erecIUea " in which he stated that in 188ft 

 over two thousand specimens were taken by means of trap lanterns at Ithaca, N.Y. 

 Last year he bred a number of specimens, and as a result of the study of the material thus 

 obtained, together with about three hundred specimens from all sections of the country^
