is eaten at the root and i.s rajndly destroyed. Tlie preventive measures adopted by 

 tlie natives consist in steeping the cuttings in a soh^tion of the pounded leaves of 

 Adhatodd vaslca,m mustard cake, or in a sohition of asafetida and common salt. An 

 account is given of the life history of the sugar-cane borer and tlie usual remedies 

 are recommended. Considerable injury is also reported from Hu'roglijphuit furcifer, 

 plant lice, and a plant bug.

The potato moth, W. W. Froggatt {Agr. Gaz. Neiv South ir«7f.s, 14 {1903), No. 4, 

 pp. 321-326, pi. 1). — A brief account of the distribution, api^earance, life history, 

 and injuries caused by this insect. A number of comi)laints have been made con- 

 cerning the damage caused by this si^ecies in various parts of New South Wales. 

 The methods recommended for controlling the insect are largely preventive, such as 

 the destruction of food plants in the fall and keeping the insect out of storerooms. 



Turnip and cabbage aphis, C. Fuller [Agr. Jour, and Min. Rec, 6 {1903), 

 No. 9, pp. 295, 296, fig. 1). — This insect is reported as doing considerable damage to 

 cabbage and related crops. In controlling the cabbage aphis the author recom- 

 mends the use of kerosene emulsion, which may be sprayed with a knapsack sprayer, 

 and the use of nicotin sheep dip. 



The larva and pupa of the apple-bud borer (Steg-anoptycha pyricolana), 

 Vj. D. Sanpeksox {Canad. Eid., 35 {1903), No. 6, pp. 153-161, fig.^^. 5). — Descri^jtive 

 and anatomical notes, especially of the mouth parts of this species. 



Bryobia ribis, R. von Hanstein (Sitzber. Gesell. Naturf. Freunde Berlin, 1902, 

 No. 6, p)p. 128-136). — This species is reported as injurious to currants, and notes are 

 given on its life history and anatomy. 



Tortrix pilleriana, J. Dufour {CJiron. Agr. Canton 'Wiud, 16 {1903), No. 11, pp. 

 307-311). — Notes are given on a numl)er of insecticide applications which were made 

 for the purpose of destroying tins pest. These remedies included black soap, oil of

 carefully regulated. 



Precocious development of pupal and imaginal organs in lepidopterous 

 caterpillars, H. Kolbe {Sitzber. Gesell. Naturf. Freunde Berlin, 1902, No. 7-8, pip. 158- 

 166). — Anatomical notes on Drndrolimus pini.

Galls and insects producing them, III, IV, and V, ]M. T. Cook ( Oluo State 

 Univ. BuL, 7. ser., No. 20, pp. 419-436, pis. 6). — The author investigated the histology 

 of a nundjer of lateral bud galls and stem galls and also studied the develoj^ment of 

 these structures. It was found that bud galls vary considerably, according to the 

 kind of insect to which they are due. Stem galls are much less variable. A com- 

 j)arison is made between galls caused by mites, plant lice, Psyllidfe, Cecidoniyia, 

 Cynipidic, and otlier insects.

 Attention is called to the desirability of maintaining a good state of cultivation, using 

 fertilizers, killing weeds, destroying badly infested plants and rubbish, in order to

 regard to the choice and application of remedies in combating insects injurious to 

 fruit trees, field crops, small fruits, ornamental i)lants, and garden crops.
