Proceedings of the Association of Economic Entomologists. Mr. Johnson 

 gave some "Entomological Notes from Maryland." He rehearsed the 

 laws of Maryland, relating to inserts and plant diseases, which requires 

 among other things, from nurserymen sending stock into the State, a 

 certificate signed by the entomologist of the State in which the stock was 

 grown, that the plants are free from insect pests and plant diseases; an 

 almost impossible certificate to give. The melon plant lice have been bad 

 in half a dozen counties, but he has found the kerosene emulsion diluted 

 twenty times to be a satisfactory remedy. The asparagus beetle is com- 

 mon everywhere, and the potato stalk beetle has done much injury. The 

 cabbage worm and harlequin bug have been unusually abundant and 

 are doing a great deal of harm. The strawberry weevils have been very 

 troublesome, particularly on the Sharpless. The Curculios have been 

 unusually injurious in peaches, and the Codling moth has been more than 

 usually troublesome in pears. The elm leaf beetle has been very abun- 

 dant, and the locust beetles has been very abundant, and the locust beetle 

 has defoliated many trees in southern Maryland. 



Mr. F. W. Webster spoke on "The insects of the year in Ohio." The 

 chief troublesome insects have been the army worm and the chinch bug, 

 and both have been injurious, though requiring different meteorological 

 condition, by the usual combination of weather in 1895 and 1896. Gra^- 

 hoppers have done much damage to hay and other crops. The harlequin 

 cabbage bug is pushing northward in|Ohio at a greater rate than ten miles 

 a year. The egg parasite that has been found doing some good in Louis- 

 iana is to be introduced into Ohio. Basket worms were very numerous, 

 and especially destructive this year. The asparagus beetle is moving 

 slowly westward in Ohio. Odontota dorsalis has been particularly inju- 

 rious on black locust this year The beetle of Saperda Candida has been 

 found feeding upon apples and doing some injury in that way. Tcrnics 

 flavipes has attacked and injured geraniums. The San Jose scale is not 

 spreading in Ohio, but is being exterminated. It has occurred heretofore 

 on young trees only, and the farmers have been willing to adopt radical 

 measures in every case. The grape root-worm has not yet disappeared, 

 but an egg parasite is beginning to increase considerably, and tin- proba- 

 bilities are that this will obtain control of the species in the near future. 

 There is also a mite attacking the eggs. No insecticides that have been 

 used against the insect have been of any practical benefit. I'algns can- 

 aliculatus was for.nd eating out fruit buds of pears, and leaf buds of ap- 

 ples. Calasoma calidum was found in the larval state attacking cut-worms. 

 Clover has been injured by a little Hernipteron, //a/ticns bniftn(u.\.
