Aphidid enemies of sorghum in the French Sudan, J. and A. Vuiixet 

 {Agron. Colon., 1 {19U), Nos. 11, pp. 137-U3; 12, pp. 161-165; 2 (19U), No. IS, 

 pp. 17-23, figs. 8). — This brief account deals with Aphis sorghi, A. maidis, and 

 Biphonophora leptadenm n. sp., their natural enemies, and means of control. 



Classification of the Aleyrodidse, II, A. L. Quaintance and A. C. Baker 

 (17. S. Dept. Agr., Bur. Ent. Bui. 27, pt. 2, tech. set: (191^), pp. 95-109, pis. 

 14). — This second part of the work previously noted (B. S. R., 29, p. 54) com- 

 pletes the classification of the family. It deals with the genera of the sub- 

 family Aleyrodinse, of which 14 are erected as new, and lists the species belong- 

 ing to each. The species Aleurotithius timberlakei n. g. and n. sp. from Cali- 

 fornia Is characterized. 



A list of unplaced species of the old genus Aleyrodes is appended. 



The life history of Psylla isitis (Psyllopa punctipennis, Crawford), the 

 "psylla" disease of indigo, A. J. Grovk and C. C. Ghosh (Mem. Dept. Agr. 

 India, Ent. Ser., 4 (1914), ^o. 6, pp. 329-357, pis. 6).— The author presents the 

 details of studies of P. isitis made during the course of investigations of enemies 

 of indigo in Behar. 



A general account of this pest and its relation to other diseases of indigo by 

 Maxwell-Lefroy has been previously noted (E. S. R., 29, p. 854). 



The lesser bud moth, E. W. Scott and J. H. Paine (U. 8. Dept. Agr. Bui. 

 lis (1914), pp. 16, pis. 2, fig. 1). — This bulletin presents the results of studies 

 of the life history and liabits and means of control of Reeurvaria nanella 

 which were carried on during 1913 at Benton Harbor, Slich. A preliminary 

 account of this pest by the authors has been previously noted (E. S. R., 31, 

 p. 262). 



This insect has attained quite wide distribution throughout the Northeastern 

 and North Central States, having been collected in New Hampshire, New York, 

 Pennsylvania, Ohio, Maryland, and the District of Columbia. Its food plants 

 include apple, pear, peach, plum, cherry, wild plum, and hawthorn. 



In rearing cages at Benton Harbor the first moths issued on June 22, the 

 maximum emergence taking place on June 30 and the last moths appearing on 

 July 10. Eggs were loosely deposited among the hairs on tlie underside of 

 apple leaves, singly or several sticking together, for the most part along the 

 veins; others were deposited on a twig under the edge of a small scale. They 

 commenced hatching about July 15. The larvae at once commence boring 

 through the epidermis of the leaf on the underside and the construction of a 

 mine in the inner tissues. On arrival of the first cold days of fall they begin 

 leaving the mines to construct small silken hibemacula in which they pass the 

 winter on the trees. After a few warm days in the spring they commence to 

 appear in great numbers. At Benton Harbor the first larv£e were observed 

 working in the buds in considerable numbers on April 15, at which time the 

 buds were just beginning to swell. By April 23 all had apparently entered 

 buds. On boring into a bud the larva makes its way directly to the center, 

 tliere feeding on the tender ovary, stamens, and pistils of the unopened flower, 

 ))rovided the insect has entered the flower bud, as the majority do. After con- 

 suming the inner portions the larva feeds upon the leafy tissue of the bud. 

 remaining within until the bud expands and the leaves begin to unfold. As 

 the first leaves open out, it fastens them together by spinning a silken thread 

 about them and constructs a shelter for itself, often rolling over the edge of a 

 leaf and constructing it from within, or bringing the tips of several leaves 

 together. It then greatly deforms and hinders the succeeding leaves as they 

 develop.
