Iia8 l)(»en had in combatiuii this insect by the nse of a mixture of nicotine, soaj), and 

 water, and also l)y the use of a mixture of pine tar, caustic soda, annuonia, and 

 water. A number of parasitic insects assists to some extent in checking the extension 

 of the pest. 



The rust mite of the orange (Jmir. Jaiiutica Agr. Soc, 7 {1903), No. 9, pp. 354- 

 ,356). — Fliijtoptus olelcorus is reported as greatly injurious to both orange and lemon. 

 The method recommended for eoml)ating this mite consists in tlie application of a 

 sulpliur-lye solution to affected trees. 



The pith moth (Laverna atra) (Bd. Agr. [London'], Leaflet 90, pp. .?, fig 1). — 

 This insect is said to be very injurious to fruit trees. Notes are given on its life 

 history. The insect can be controlled to some extent by collecting and destroying 

 dead shoots before the moths emerge in June. Late spraying -with Paris green is 

 also recommended. 



Insects injurious in cranberry culture, J B Smith ( U. S. Dept. Agr., Farmers' 

 Bid. 178, pp. 32, figs. 12). — The insects which attack cranberries are classified accord- 

 ing as they injure the leaves, stem, or fruit. The species which are most injurious 

 to foliage are Evdemis vacciniana, Teras minnta, Cecidomyia oxycoccana, and Cleora 

 pampinaria; the most important species injurious to the stem is Cramhus hortuellus; 

 while the chief insect pests of the cranberry fruit are Mineola raccinii. and Scudderia 

 texensis. Notes are given on the habits, life history, and means of combating these 

 various species. A number of other less important insect pests are also mentioned 

 and notes are given on cultural methods which are best adapted to prevent insect 

 ravages. It is suggested that an ideal cranberry bog should be as level as possible, 

 not too extensive, and should be conveniently located to reservoirs, with which it 

 should be connected by means of ditches. 



Is the fight against phylloxera futile ? J. Dufour {Chron. Agr. Canton Vaud, 16 

 {1903\, No. 13, pp. 375-381) . — In various parts of the Canton de Vaud it is said that 

 this insect is on the increase, despite all measures which have been taken for com- 

 bating it. Statistics are presented showing the gradual distribution of the pest. The 

 author believes, however, that the fight against this insect should not be given up 

 and presents reasons for holding out the hope that ultimate success may be reached 

 by the use of American vines and approved insecticide methods. 



Fumigation for the destruction of the grape-leaf roller, J. Perkaud ( Compt. 

 Rend. Acad. Sei. I'nris, 136 {1903), No. 24, pp. 1485-1 487). Since the larva; of 

 this insect winter over under the bark of grape trunks, fumigation with sulphur was 

 employed for destroying them. It was found to be quite safe and effective to inclose 

 the trunks in a metallic jacket only slightly larger than the trmiks and to burn 

 sulphur in this small space. The larvfc were killed in almost all cases. It is recom- 

 mended that fumigation should not be practiced under freezing temperature or 

 iniiiiediately after rain. 



A dipterous parasite of the grapevine flea-beetle, C. Yi.xney and II. Conte 

 {Bid. Agr. Algerie et Timlsie, 9 {1903), No. 14, p. 326). — The grapevine fiea-beetle is 

 considered one of the worst enemies of grapes in Algeria, and observations made by 

 the authors indicate that the parasitism of this insect by Degeeria fmiehrls may assist 

 materially in the destruction of the pest. 



Cankerworms, "W. '^l. Munson {Maine Sta. Bui. 95, pp. 121-124, figs. -?)• — Brief 

 descrijjtive, economic, and biological notes on spring cankerworm and fall canker- 

 worm. The remedies recommended for this insect include the use f)f bands of tarred 

 paper or other substances and sjjraying with Paris green or arsenate of lead. 



Departmental notes on insects that affect forestry, II, ¥.. P. Stebbing 

 {Calcutta: Supt. Govt. Printing, India, 1903, pp. VTI+ 15 1-334, pis. 7J).— This number 

 is a continuation of the author's extensive notes on forest insects of India (E. S. R., 

 14, p. 472) . A large number of species belonging to various orders of insects are dis- 

 cussed in detail, and the majority of specdes are excellently illustrated. Many of the
