The woolly aphis and the apple in Argentina, J. M. Huergo (Bol. Min. 

 Agr. [Buenos Aires], 13 (1911), No. 7, pp. 358-401, pi. 1, figs. 22).— A brief ac- 

 count is given of the injury caused by the woolly aphis in Argentina, with direc- 

 tions for combating it. 



White fly control, E. W. Bergek (Fla. Quart. Bui. Agr. Dept., 22 {1912), 

 No. 2, pp. 38-113). — This is a summarized account of recent work. 



Notes on Cuban white flies with description of two new species, E. A. 

 Back (Canad. Ent., U {1912), No. 5, pp. 1^5-153, figs. 7).— Nine species are 

 recorded from Cuba, of which Aleurodicus cardini, taken from the guava 

 {Psidium guajava radii) at Havana and Santiago de las Vegas, and Aleyrodes 

 trachoides, taken from an indigenous solanaceous vine {Solanum seaphorthi- 

 anum) at Santiago de las Vegas, are described as new to science. A. cardini 

 is said to become quite abundant on guava at times and when not parasitized 

 becomes the source of injury. In May, 1911, the author received specimens from 

 Cuba, over 90 per cent of which had been parasitized by a hymenopteron. 



The other species recorded from Cuba are Aleyrodes citri, A. nuMfera, A. 

 howardi, A. variaMlis, A. floridensis. A. mori, and Paraleyrodes persew. 



A new coconut pest, D. B. Mackie {Philippine Agr. Rev. [English Ed.], 5 

 {1912), No. 3, pp. 142, 143, pi. i).— The coconut white fly {Aleurodicus de- 

 structor), first collected in the vicinity of Guijulngan in May, 1911, is said to be 

 confined to a district in Negros Oriental, extending from the barrio of Tabon 

 on the north and the barrio of Zamora on the south, a range of some 35 km, 

 (about 21.7 miles) in length. Most of the coconut groves in this area, which 

 extends from the seacoast back to a range of hills to the west, are infested.

 tions for combating L. cerasifex, which appeared in orchards at Kamouraska,

Native and foreign parasites of Diaspis pentagona, so far known and 

 introduced into Italy, G. Martelli {Ahs. in Internat. Inst. Agr. [Rome], Bui. 

 Bur. Agr. Intel, and Plant Diseases, 2 {1911), No. 6, pp. 1521, 1522).— This is a

Gipsy and brown-tail moth suppression, F. W. Rane {Ann. Rpt. State 

 Forester Mass., 8 {1911), pp. 81-144, P^s- 4)- — Details of the work of the year 

 with these 2 pests are presented. 



A newly invented power truck sprayer from which the tank can be easily re- 

 moved, and the truck then used the same as any truck, is described. With this 

 sprayer it is possible to spray both sides of the highway at the same time, while 

 traveling. 



A brief report of the work of the year with insect parasites by Dr. L. O. 

 Howard is included. The recovery in large numbers of the Japanese egg 

 parasite of the gipsy moth, Schediiis kuvance, was a very encouraging feature 

 of the summer's work. Field observations showed that it had practically be- 

 come established and that in some localities 30 per cent of the eggs in a given 

 mass had been destroyed by it. The parasite " Monodontomerus cereus, which 

 attacks the gipsy and brown-tail moths in the pupal stage, is now to be found 

 practically over the whole of eastern Massachusetts, in several towns near
