barrier was placed at the crown of the tree, the larvie made no attempt to enter 

 above it. 



Experiments with lime-sulphur spray against the larch moth (Coleophora 

 laricella), I. Tkagardh {Centralanst. JordbniksfiJrsdlc Flyubl. 49 (PJl/f), pp. 3; 

 abs. in Rev. Appl. Ent., 8 (1915), Ser. A, No. J^, p. 191).— The author's experi- 

 ments confirm the results obtained by Herrick (E. S. R., 28, p. 857), showing 

 that lime-sulphur spray is an excellent remedy for the larch moth. 



The burdock gelechiid, an insect seed destroyer, A. Gibson (Ottawa Nat, 

 28 (1914), No. 7, p. 96; abs. in Rev. Appl. Ent., 3 (1915), Scr. A, No. 2, p. 72).— 

 The author reports that nearly every seed head of the lesser burdock (Arctium 

 minus) in the Ottawa district is found to harbor one or more larvrc of Mctz- 

 neria lappeUa througli the autumn and winter. In this way the lepidopteran 

 becomes a useful insect. So abundant has the insect become that it is the 

 exception to find a seed head in which the small caterpillar is not wintering. 



Fumigation for the box leaf miner, E. P. Felt (Jour. Econ. Ent., 8 (1915), 

 No. 1, pp. 94-96). — ^A brief report of experiments with Monarthropalpns buxi, 

 wliich has become well established on Long Island, where it is seriously injuring 

 ornamental box hedges. 



Preliminary experiments indicate that fumigation with one toaspoonful of 

 carbon bisulphid to 5 qt. of space for a period of at least one hour will kill the 

 larvffi without injury to the plant. Tests of carbon tetrachlorid, C. P. ammonia, 

 and naphthalin flakes were made with less favorable results. Fumigation for 

 15 minutes with potassium cyanid at the rate of 1 dram to 27 cu. ft. of space 

 or about one-half the strength recommended for fumigating nursery stock de- 

 stroyed some of the larvae and did not injure the foliage. 



A caterpillar (Oria musculosa) injuring grain crops and methods of com- 

 bating it, N. ViTKOvsKY (Abs. in Rev. Appl. Ent., 2 (1914), Ser. A, No. 12, p. 

 712). — A popular account of tliis most serious pest of grain crops in so\ith 

 Russia and means for its control. In one district in the Province of Don 2,700 

 acres of crops were damaged, of which 810 acres were totally destroyed. 



The question of fighting Oria musculosa, A. O. Fabkikant (Zetnl. Ghaz., 

 No. 35 (1914), pp. 1137, 1138; abs. in Rev. Appl. Ent., S (1915), Ser. A, No. 1, 

 p. 15). — The author reviews the work of a special conference on the control of 

 O. (Tapinostola) musculosa. During 1912 its damage to crops in the Govern- 

 ment of Ekaterinoslaf amounted to as high as $1,289,622.50, as many as 54,000 

 acres of crops being totally destroyed and 67,000 acres damaged in only five 

 districts of the Government. 



Oria musculosa in the Government of Ekaterinoslaf according to the data 

 for 1914. — Distribution, biology, and method of control, N. N. Vitkovsky 

 (Abs. in Rev. Appl. Ent., 3 (1915), Ser. A, No. 3, pp. 110, 111).— An account of 

 the life history of this noctuid which was the source of considerable injury 

 during 1914. See also notes above. 



Mycodiplosis macgregori n. sp., E. P. Felt (.Jour. Econ. Ent, 8 (191.5); No. 1, 

 p^ 149). — This itonidid was reared from red spider on cotton at Batesburg, S. C. 



Malaria in the Philippine Islands.— I, Experiments on the transmission 

 of malaria with Anopheles (Myzomyia) febrifer sp. nov., A. (Pseudomy- 

 zomyia) rossii, A. (Myzorhynchus barbirostris, A. (Myzorhynchus) sinensis, 

 and A. (Nyssorhynchus) maculatus, E. L. Walkek and M. A. Barber (Philip- 

 pine Jour. Set., Sect B, 9 (1914), No. 5, pp. 381-439) .—The authors' experi- 

 ments show that among the anopheline mosquitoes in the Philippine Islands A. 

 febrifer is probably the most susceptible to infection with the parasites of sub- 

 tertian malaria, and while the number of experiments with tertian and quartan 

 malaria is insufficient to determine the fact, it is probable that this species is 

 also an efficient carrier of these types of the disease. " This species is from
