^V. Lockhead discussed Injurious Insects of Ontario. The Hessian 

 tly and pea Avecvil were unusually abundant. It Avas stated that there 

 are man}' voluntary observers studying- the ha})its of these insects. 

 The pea weevil can now be controlled by proper insecticide and cul- 

 tural methods. The clover-seed niidoe destro3^ed aliout one-fourth of 

 the clover seed of Ontario, and is considered a very serious pest. The 

 lime-sulphur-salt treatment was found to be exceedingly efiective for 

 San Jose scale and pear psylla. Notes were also given on squash bug, 

 asparagus beetles, and cucumber beetles. 



fl. f'letcher spoke on The Insects of Canada. Clover thrips is 

 always abundant on clover blossoms in Canada, but it is not certain 

 how much injury this insect does. It apparently damages oats. Notes 

 were presented on oyster-shell bark-louse, asparag'us beetles, cut- 

 worms, pear-leaf blister-mite, cabbage maggots, onion maggots, horn- 

 fl}'^, fleas, and bedbugs. The author argued that all insecticide fornui- 

 las must be made as simple as possible in order to induce farmers to 

 apply them properly. ; 



H. Osborn discussed Ohio insects) with special reference to fall web- 

 worm, apple maggot, Capsida?, and leaf hoppers. 



E. D. Sanderson spoke of the injurious insects of Texas for 1903. 

 There are apparently 3 species of grain plant lice in Texas. The 

 chinch ))ug has 3 broods and is reported to have caused considerable 

 loss during the A^ear. Insect injury to cotton was chiefly due to grass? 

 hoppers, white grubs, white-lined sphj'nx', and Zoxostege similalis. 

 Pecans were injured b}^ a species of Phylloxera and by AcroJxtsis 

 carycje. Notes were also given on the fowl tick, sweet- potato weevil, 

 and Aphis scotti, which was referred to as a new species injurious to 

 plums. 



T. B. Sj^mons discussed the Maryland insects. The San Jose scale 

 is now controlled by lime-sulphur-salt wash. Economic notes were 

 given on apple aphis, strawberry weevil, fruit-tree bark-beetle, tent 

 caterpillars, cucumber beetles, asparagus beetles, melon aphis, straw- 

 berry aphis, scurfy bark louse, and oyster-shell bark-louse. The 

 cigarette beetle was said to be in almost every tobacco warehouse in 

 Mar\'land and great difficulty has been experienced in exterminating 

 it. The speaker recommended a regular inspection of tobacco ware- 

 houses. 



F. L. Washburn spoke of injurious insects in Minnesota. Notes 

 were given on plant lice and white grubs, especially Lachnosterna 

 rvgos<(^ which were said to be unusually abundant and injurious to 

 sorghum, wheat, barle}', evergreen trees, and other plants. Mention
