Miscellaneous injurious insects, C. V. Piper and \l. W. DoANE 

 {Washington Sta. Bui. So, pp. 24, figs. 13). — On account of the rapidity 

 with which the San Jose scale has spread over the State and the great 

 amount of damage it is causing, the authors have given descriptive 

 notes and an account of the life histor.y of this insect. The most 

 approved remedies for the destruction and prevention of the distribu- 

 tion of the scale are given. 



The bud moth (Tmetocera ocellana), which was unknown within the 

 State 3 years ago, is now reported as having gained a foothold in sev- 

 eral sections and has done much damage wherever noted. The appear- 

 ance of the insect at different stages of development is described. The 

 remedies suggested for combating it are spraying trees with Paris 

 green during the early stages of the larva-, or just as the larva 1 are leav- 

 ing winter quarters and beginning to eat their way into the buds. On 

 account of the peculiar habits of this insect these are about the only 

 periods at which it can be successfully treated. 



The strawberry crown moth (Sesia rutilans) is figured, its habits and 

 life history described, and remedies suggested. The best, surest, and 

 easiest way to control this pest, the authors state, is to watch the plants 

 early in the spring and dig out and ("sstroy by burning any dead and 

 dying plants, or any that from weak condition seem to indicate that 

 they may be infested. 



The plum sphinx (Sphinx albescens) is figured and described. When 

 abundant the trees should be sprayed with Paris green for the preven- 

 tion of injury. Hand picking, however, will ordinarily be sufficient to 

 keep these insects in check. The sphinx is parasitized by a small wasp- 

 like insect (Rhogas fumipennis). 



Illustrated notes are given on the tomato worm and blister beetles, 

 with suggested remedies. 



The strawberry thrips and the onion thrips, A. L. Quaintance 

 (Florida Sta. Bui. 46, pp. 77-114, figs. 12). — The author reports the 

 occurrence of Thrips tritici during the spring seasons of 1896 and 1S!I7, 

 when it proved quite destructive to strawberries and other crops. 

 The insect is said to be present in Florida throughout most of the year, 

 but it was only during March, April, and May in the 2 seasons indi- 

 cated that serious damage was done. In both these seasons the straw- 

 berry crop of Florida was reduced fully one-third by the action of these 

 insects. The thrips attacks the pistils of the strawberry most fre- 

 quently, resulting in the blighting of the ovaries. In addition to the 

 attacks on the pistils, the petals, particularly at their bases, and also 

 the stamens are attacked to some extent. The injurious effect of these 

 insects seemed to be in preventing the fertilization of the ovules. 

 Since the stigmas are attacked, the normal fertilization is greatly 

 retarded, if not entirely prevented. 



In March, 1898, the thrips was very abundant about Lake City ami
