wetted with miscible oil and nicotine sulphate. The usual time for 

 this application is about the middle or latter part of April in the 

 Hudson Valley. If the infestation is severe, the spray should be 

 repeated in about three or four days. A spray of lime-sulphur and 

 Bordeaux mixture with the addition of f pint of nicotine sulphate to 

 every 100 gals, of spray should be applied when the cluster buds 

 are separating. For the destruction of the larvae on the fruit, nico- 

 tine sulphate may be added to the usual Bordeaux or lime-sulphur 

 spray, or nicotine sulphate and soap may be used.

 4 plates, 2 charts, 17 figs. [Received 28th April 1921.] 



The economic importance of insects in crop standardisation depends 

 largely on their destructive influence on crop production. The insects 

 attacking apples are described and grouped according to the injuries 

 they produce. A key is also given for the identification of injuries to 

 mature apples and directions are given for a routine system of 

 spraying. 



The insects dealt with are : — Cydia (Carpocapsa) pomonella, L. 

 (codling moth) ; Enarmonia prtmivora, Wlk. (lesser apple worm) ; 

 Cydia (Laspeyresia) molesta, Busck (oriental fruit moth) ; Rhagoletis 

 pomonella, Walsh (apple maggot) ; the green fruit worms, Graphiphora 

 alia, Gn., Xylina anteiinaia, Wlk., Graptolitha {X.) laticinerea, Grote, 

 and X. grotei, Riley ; Tortrix {Arc-hips) argyrospila, Wlk. (fruit-tree 

 leaf-roller) ; Dickomeris {Ypsolophiis) ligulella, Hb. (palmer worm) ; 

 Tortrix (Archips) rosaceana, Harr. (oblique-banded leaf-roller) ; 

 Hemerocampa leucostigma, S. & A. (white-marked tussock moth) ; 

 Eucosma {Tmetocera) ocellana, Schiff. (bud moth) ; the apple red 

 bugs, Lygidea mendax, Rent., and Heterocordylus malinus, Reut. ; 

 Conotrachelus nenuphar, Hbst. (plum curculio) ; Anthonomns quadri- 

 gibbus, Say (apple curculio) ; Aphis sorbi, Kalt. (rosy apple aphis) ; 

 Aspidiotus perniciosHS, Comst. (San Jose scale) ; Macrodactylus 

 subspinosits, F. (rose chafer) ; the case-bearers, Coleophora fletcherella.

Referring to a recent article on the pink bollworm [Platyedra gossy- 

 piella) [R.A.E., A, ix, 269] an appeal is made to cotton growers 

 in Texas to back up the efforts of the State entomologists to combat 

 this pest.

This useful handbook is the first of a series of three vohmies which 

 aim at giving briefly as complete a summary as possible of the 

 chief subdivisions of the Coleoptera of Europe. The classification of 

 genera is based upon that of Lacordaire (1854-1876), with certain
