It is stated that a grower who cultivates a large area of apples and 

 pears, has noticed that during the past two years his trees were later in 

 bursting than usual. As this cannot be accounted for by weather 

 conditions, it is attributed to annual spraying wdth alkaU wash.

 Scot. Nat., Edinburgh, no. 39, March 1915, p. 70. 



Cryphahis abietis, Ratz., is recorded on silver fir {Abies fectinata) 

 from near Aberdeen. Larvae and adults were found in great numbers, 

 the galleries being chiefly in the bark, while the beetles were always 

 found in dead, lopped- off branches. Although numerous spruce 

 trees {Picea excelsa) occurred in the neighbourhood, none were attacked.

Stress is laid on the necessity of thoroughly investigating insects 

 and their attacks upon vegetation, regardless of whether they are 

 injurious at the time or not. The author has occasionally been 

 criticised on account of having apparently spent time and funds m 

 studying insects whose attacks were, so far as then known, of little or no 

 importance. These restrictions were not always warranted and the 

 author mentions, from his own experience and that of others working 

 under his direction, the following insects which, when first observed, 

 were either of no economic importance or of which the importance was 

 not then suspected : Myochrous denticoUis (the southern corn beetle), 

 Cerotoma caminea, Diabrotica 12-panctata, Sitones hispidulus (the 

 clover-root curculio), Phytometra calif ornica and Toxojitera graminwn. 



AiNsLiE (G. G.). A New Aphid from Florida. — Canadian Entomologist, 

 London, Ont., xlvii, no. 3, March 1915, pp. 85-88. 



•Carolinaia cyperi, sp. n., is described. This aphid was first found 

 at Lakeland, Florida, in November 1912. It appears to be rather 

 generally distributed throughout Florida on its only observed food- 

 plant, Cyperus escidentus, which, in its wild form, is the troublesome 

 nut-grass of the south and, in cultivation, is known as chufa. C. cyperi 

 thrives on chufa in cages and forms colonies on it readily in the field. 

 It lives only on the uiider side of the leaves, which never seem to show 

 the slightest efEect of its presence even in large numbers. When 

 found in November, the colonies, then rather small, consisted of 

 apterous adults, young, and an occasional alate form. In January, 

 almost every plant in the field bore large colonies, but winged adults 

 were very scarce. When transferred to a cage, winged forms appeared 

 at once, indicating that they had been developing, but leaving the 

 parent colony as soon as mature. The large colonies persisted in the 

 field and became verv abundant until about the middle of March,
