blossoms of the orange and lemon. It is found in Sicily and in the 

 Provinces of Calabria and Campania. The species of spider mite seen 

 in all citrus-growing districts of Spain and Italy is identified by the 

 Italian entomologists as Tetranychus ielarius. What has been called 

 T. telarius in the United States has recently been made synonymous 

 with T. himaculatus, Harv. [see this Review, Ser. A, iii, p. 63]. 

 The author is of opinion tha.t, judging from their difference 

 in feeding habits, the bimacidatus of the United States and the 

 European telarius are not synonymous, if the Mediterranean 

 citrus species is properly identified as telarius. Another spider 

 mite, probably a Toiui palpus, was occasionally met with on 

 citrus foliage in Sicily. The fruit of the orange is sometimes injured 

 by a thrips, said to be Heliothrips fascialus, Perg. With the exception 

 of a little fumigation in Spain for the control of C. dictyospermi, and 

 hmited spraying in Italy for the same insect, practically no remedial 

 measures are taken against citrus fruit insects in the countries bordering 

 on the Mediterranean. Spanish growers state that in actual practice 

 the cost of fumigation varies from about Is. to Is. 3d. per 

 tree. In Sicily, the use of lime-sulphur advocated by Savastano 

 is becoming popular for the control of C. dictyospernd. Dr. G. 

 Brigante states that Prays citri may be controlled by a 1 per 

 cent, solution of lead arsenate. Poison sprays are, however, iu 

 bad repute in Italy. Of the citrus insects discussed above, two do 

 not occur in the United States, namely, C. capitata and Prays citri. 

 Two others, C dictyospermi and P. zizyphus, occur, but do not appear 

 to be important pests, as is the case in the Mediterranean region. 

 The two former insects could be controlled in the United States by 

 the methods now in use there. This fact, however, should not prevent 

 quarantine measures being taken against them. A brief survey of 

 the Mediterranean citrus fruit industry concludes this paper.

In Bombay, special attention has been paid to the control of 

 Sclioenobius bipunctifer, which moth is a serious pest of rice. In 

 the Central Provinces, large numbers of Canthecona furcellata, a 

 Pentatomid bug predaceous on caterpillars, were bred and liberated 

 in cotton and gram fields to check attacks on these crops. In the 

 United Provinces, demonstration was made in the Farrukhabad 

 District of methods of storing seed potatoes to avoid attack of 

 Phthorimaea operculella (the potato moth), which is now widely dis- 

 tributed there, though as yet it has apparently not reached the Hill 

 Districts. In the Punjab, the work done was mainly on pests of cotton 

 and stored grain, and living specimens of RJiogas lefroyi, a Braconid 

 parasite of the cotton bollworm {Earias), have been supplied from time 

 to time from Pusa. The sugar-cane crop in the North- West Frontier 

 Province was badly infested with borers, over 50,000 egg-clusters 

 having been picked from one experimental plot of six acres. Gelechia 

 gossypiella did considerable damage to the cotton crop, late-ripening 

 varieties being attacked most severely, while local cotton, Gossypium 

 neglectum, which ripens and is picked before mid-October, practically
