destructor). Wheat Midge {Cecidomyia tritici), Pear Midge {Contar- 

 inia pyrivora), Violet Midge (C. violicola), Sorghum Midge (C. sorg- 

 hicola), Cotton Midge (C gossypii), Box Elder Midge (C. negundi- 

 folia), and other still unnamed species attacking various plants. 

 Attention was then called to several beneficial species, especially those 

 of the genus Aphidohtes, which live on aphids. Towards the close of 

 the paper, the interesting preferences in regard to food plants shown 

 by Cecidomyiids were referred to. For instance, 39 species have 

 been reared from Solidago, 28 from Salix, 16 from Aster, and 10 

 from Grape. The wide field for study in this great family of tiny 

 insects was shown from the fact that there are already 700 American 

 species known, representing 50 genera. 



In his address on "Natural Enemies of Some Ontario Coccida?," 

 Mr. A. Eastham gave the results of a year's careful rearing and 

 study of the chief enemies of the more common scales in the vicinity 

 of Guelph, viz.: Lepidosaphes ulmi, EnJecanium ccrasifex, E. caryae, 

 E. fletcheri, Pulviiiaria innuyyierabilis, and Aspidiotus ostreacformis. 



Each paper was followed by a discussion so far as time permitted. 



At the evening meeting of this day. Professor W. Lockhead, of 

 ]\racdonald College, St. Anne cle Bellevue, Que., read a paper on 

 "What Entomology the Farmer and Fruit-grower Should Know." 

 He was followed by Dr. Fyles, of Levis, Que., with a popular address 

 entitled, "The Farmer's Woodlot." Dr. Bethune then read a paper 

 from Dr. L. O. Howard, of Washington, D. C, on "The Present Con- 

 dition of the Work Connected with the Importation of Foreign Para- 

 sites of the Gyp.sy and Brown-tail Moth." 



In this paper. Dr. Howard mentioned certain very important 

 innovations made in the work the last year or so. These were as 

 follows: (1) The laboratory has for greater convenience been 

 removed to Melrose Highlands, Mass. (2) A man thoroughly 

 equipped in the biology of his special group has been put in charge 

 of each division of the work, so that now a Hyraenopterous expert 

 looks after the Hymenopterous parasites, a Dipterous after the Dip- 

 terous, and a Coleopterous after the Celeopterous. (3) In order 

 that parasites shall leave Europe in a better condition to stand the 

 ocean voyage and arrive in a good state at New York, a general lab- 

 oratory depot has been established at Rennes, France, under a trained 

 man. All shipments are looked over and properly packed by him and 

 forwarded in the quickest and best way possible. (4) An agent 

 has been sent to Japan, where parasites are known to keep the Gypsy 

 Moth under complete control, and these insect allies are now arriving 

 in large numbers. Not a fcAv of them have alreadv been colonized.
