REAPPEARANCE OF ICERYA PURCHASI. 



We learn from a receut California journal that the Fluted Scale has 

 made its appearauee in considerable numbers at St. Helena, Najja 

 County. This is quite in accordance with our predictions, for we have 

 by no means believed that the pest was fully exterminated by the 

 Vedalia. 



THE PeIr MIDGE IN NEW YORK. 



We have not yet noted the fact that Dr. Lintner has discovered the 

 Pear Midge {Diplosis pyrivora), which we treated in our xVnnual Report 

 for 1885, along the Hudson Kiver. Up .to the past year it was known 

 only ni the single locality near Meriden, Conn., where we studied it. 



A POSSIBLE NEW INSECTICIDE. 



O. Loew, in the Berichte der Deutschen Chemischen Gesellschaft, 

 XXIII, page 3203, announces that hydrazine sulphate in the proportion 

 of one-lifth of a gramme to 1 litre of water kills innnediately algte, fission 

 organisms, molds, schizomycetes, and other low types of water organ- 

 isms. It is also poisonous upon dogs and Guinea-pigs, and unfortunately 

 is also injurious to young shoots and buds of plants. The Gardener's 

 Chronicle for August la recommends its trial under the head of "A 

 New Insecticide," but Its deleterious effect upon both plant life and the 

 life of mammalia would apparently restrict its use to the comparatively 

 small group of household pests. 



BITTEN BY A KATIPO. 



We are indebted to Mr. R. Allan Wight, of Auckland, New Zealand, 

 for the following clipping from a New Zealand jiaper : 



Auckland, May 11. 

 A few days ago the well-known waterman of this port, Harry Keane, received a 

 bite from what he states was a Katipo, while down on the island of Motutapii rabbit 

 shooting. The bite resulted in great pain and considerable swelling of the leg on 

 which he was bitten. He has been in the hospital ever since, ard it is not yet cer- 

 tain whether he will not lose his leg.
