On the structure and biology of Tachardia lacca, with observations on 

 certain insects predacious or parasitic upon it, A. D. Imms and N. C. Chat- 

 TERJEE {Indian Forest Me7n., Forest Zool. Ser., 3 {1915), No. 1, pp. Jf2, pis. 8). — 

 Historical notes are first given, followed by a discussion of the systematic po- 

 sition of this coccid, the secretion and chemical composition of lac, its life 

 history, distribution in India, and chief food products, together with descriptions 

 of its several stages, habits, insect enemies, etc. A bibliography of 29 titles is 

 included. 



The rice stem borer in the Konkan, R. S. Kasaegode and V. G. Deshpande 

 {Dept. Agr. Bombay Bui. 69 (1915), pp. 18, pi. i).— This is a detailed account 

 of Schocnobius bipunctifer, a lepidopteran which occurs throughout the greater 

 part of the Indian rice area. It is the source of a large percentage of the insect 

 injury to rice, which is rarely less than 10 per cent of the crop and may be as 

 high as 60 per cent. The caterpiUar attacks the plant at some point in the stem, 

 which soon withers and turns white. Sis days are required for its embryonic 

 development, 27 for the larva, and 9 for the pupa, or a total of 42 days for the 

 life cycle. 



Climate and variations in the habits of the codling moth, E. P. Felt 

 {Jour. Econ. Ent., 9 {1916), No. 1, pp. 107-110).— It is the author's opinion 

 that, if conditions obtaining in New York during the past two or three years 

 are reliable criteria, climatic differences exert a considerable influence upon 

 the habits and the tj'pe of injury caused by the codling moth. 



Notes on crambids, G. G. Ainslie {Jour. Econ. Ent., 9 (1916), No. 1, pp. 

 115-119). — Miscellaneous notes relating to the methods of rearing, etc., of 

 crambids. 



The control of the grape berry worm (Polychrosis viteana), W. H. Goodwin 

 {Jour. Econ. Ent., 9 {1916), No. 1, pp. 9i-i 06). —Substantially noted from an- 

 other source (E. S. R., 35, p. 358). 



Preliminary studies of the biological control of the grapevine pyralid 

 ((Enophthira pilleriana), F. Schwangaet {Naturiv. Ztschr. Forst u. Landw., 

 IS {1915), Nos. 8-9, pp. 380-408; 11-12, pp. 522-54i ) .—The first part of this 

 paper (pp. 380-398) deals with parasites of (E. pilleriana, particularly the dip- 

 terans Prosopodes fugax, Nemorilla maculosa, Gymnoparea {Actia) pilipennis, 

 and Cyrtoneura stabulans. The second part (pp. 398-408, 522-534) consists of 

 a discussion of the parasites of Hyponomeuta and their relation to the vine 

 leaf rollers {CE. pilleriana, Clysia ambiguella, and Polychrosis botrana), and the 

 third part (pp. 534-541) comprises conclusions, etc. 



The pilotaxy of Anopheles, S. R. Cheistophees {Indian Jour. Med. Re- 

 search, 8 {1915), No. 2, pp. 362-370, pi. i).— This article deals with the more 

 important chsetfe of Anopheles. 



The male genitalia of Anopheles, S. R. Cheistophees {Indian Jour. Med. 

 Research, 3 {1915), No. 2, pp. 371-394, pls. 6). — An anatomical study which in- 

 cludes descriptions and drawings of the genitalia of most of the oriental species 

 of Anopheles and of such others as were available. The author considers the 

 genitalia to be the most satisfactory means for classifying the group. 



Dasyneura ulmea, a new elm pest, J. S. Houses {Jour. Econ. Ent., 9 {1916), 

 No. 1, pp. 82-84, fiff- -')• — The author reports that this itonidid is the source 

 of injury to elms in Ohio. Its attack results in the formation of from 1 to 20 

 aborted bud galls, usually at the twig tips, which cause a check in the branch 

 development and an ultimate stunting and malformation of the tree. 



A new Phanurus from the United States, with notes on allied species, 

 A. A. GiBAULT {Canad. Ent., 48 {1916), No. 5, pp. 149, 150). — Phanurus emersoni 

 n. sp., reared from tabanid eggs at Dallas, Tex., and three allied species are 

 described.
