fore found in cottonwood. The proposed remedies are the 

 same as for the imported borer, cutting and burning infested 

 stems. The currant has now a respectable Hst of insect pests ! 



''Webster gives some account of the strawberry crown- 

 borer* ^Tyloderma fraga7'i(B) and describes the egg. A jump- 

 ing beetle {Haltica igfiita) has been found injurious near 

 Columbus, Ind., and has been also complained of from Arizona 

 and Florida. The beetle is widely distributed and is a close 

 ally of the grape flea-beetle ; it may therefore become one of 

 the pests of the future. No suggestions as to remedies are 

 made. 



*' J. B. Smith has treated monographically f the insects in- 

 festing the cranberry, giving the life-history of all the species 

 and the means of destroying them. He strongly recommends 

 laying out the bogs so that they can be flooded readily and 

 the insects drowned out. He has during the past season put 

 his own recommendations to practical use and the results, 

 eminently satisfactory, will appear in the forthcoming annual 

 report of the Station. 



''Weed has continued his experiments with the striped cu- 

 cumber beetle, and finds tobacco dust most successful, after 

 mechanical covering of the plants. J Smith reports § similar 

 success with tobacco for this beetle, and gives also the results 

 of a series of experiments on the squash borer, none of which 

 were entirely satisfactor}^ 



"Miss Murtfeldt reports || a new rose slug {Cladius isome- 

 ras) as injurious in Missouri, and suggests hellebore as a 

 remedy. J. G. Jack finds ^ that an European saw-fly {Emphy- 

 tus cinctus, injured roses at the Arnold Arboretum. Riley and 

 Howard have described ** a new icerya (/. rosce^, injuring roses 

 at Key West. 



"Bailey has made a series of interesting experiments ft to 

 ascertain the amount of injury to peach foliage by applications 

 of Paris green and London purple. He concludes that London 

 purple should not be used on peach ; that Paris green at the 

 rate of i lb. to 300 gal. of water, in a fine spray, did not injure 

 foliage, and that i lb. to 350 gallons of water would probably 

 be always safe. He found that nearly 40 per cent of London
