last few years, especially in 1911, and has been a source of considerable damage 

 to beets. The authors confirm the observations of Mordwilko. who considers 

 this species to be the same as that found on Euonymns europwus in spring and 

 known as A. euonymi. 



Notes on coccids which attack the coconut palm and other plants culti- 

 vated on a large scale in Mahe, Seychelles, P. R. Dupont (Abs. in Rev. Appl. 

 Ent., 1 (1913), Ser. A, No. 4, pp. 129, ISO). — Seven species of Lecanium are 

 mentioned as occurring in the Seychelles. A species of fungus of the genus 

 Hypocrella is said to attack these scales; a species of Microcera attacks 

 Diaspis pentagona, which injures the leaves of plum trees and the trunks of 

 papaws; and Cepfialospormm lecanii parasitizes Lecanium viride, which has 

 caused the disappearance of almost all the thorn-bearing trees in the Colony. 



Some field notes on a soft gray scale known locally as the " longulus " 

 scale, D. Kell (Mo. Bui. Com. Hort. Cah, 2 (1913), No. 8, pp. 617-619).— 

 Biologic notes and a brief report in tabular form upon experimental fumiga- 

 tion work are given. See also a previous note (E. S. R., 28, p. 452). The re- 

 sults indicate that there is a good chance of obtaining a fairly high destruction 

 of this scale by fumigating between July 20 and the end of August. 



The tobacco caterpillar (Prodenia litura), C. R. Jones (Philippine Agr. 

 Rev. [English Ed.], 6 (1913), No. 9, pp. 425-432, pi. 1, figs. 2).— This noctuid is 

 said to be the greatest pest of tobacco in the Philippines, the larvae attacking 

 growing tobacco, both young and old, but causing the greatest damage to the 

 young leaves. This paper presents an account of its life history and habits 

 with remedial measures. 



The cotton worm in Egypt, G. C. Dudgeon (Bui. Imp. Inst. [So. Kensington'], 

 10 (1912), No. 4, pp. 584-620, pi. 1, fig. 1). — A summarized account of Prodenia 

 li'fura (litoralis) including its synonymy, distribution, life history, control, etc. 



Recent work on the polyhedral body disease of caterpillars, K. Escherich 

 (Natunv. Ztschr. Forst u. Landw., 11 (1913), No. 2, pp. 86-97, fig. i).— This is a 

 critical review of recent literature on the wilt disease of caterpillars. 



The rice caterpillar (Laphygma frugiperda), G. E. Bodkin (Jour. Bd. Agr. 

 Brit. G-uiana, 6 (1913), No. 4, pp. 172-183).— In British Guiana the fall army 

 worm is an extraordinarily destructive pest, occurring in countless numbers 

 in the young rice nurseries when the plant is at the most critical stage of its 

 growth. If control measures are not immediately taken it destroys the entire 

 nursery in a short time. In this paper the author deals with its distribution, 

 life history, natural enemies, and means of control. 



A serious Philippine orange moth (Prays citri), E. O. Essig (Mo. BuL Com. 

 Hort. Cal., 2 (1913), No. 11, pp. 722, 723, fig. 1).—The larv?e of this pest is said 

 to live just beneath the rind next to but not in the pulp of the cajel, a variety 

 of the native orange, and to produce gall-like swellings which remain opened at 

 the outside but do not seem to penetrate the pulp at all. 



A pest of oranges (Agr. Neics [Barliados], 12 (1913), No. 302, p. 378).— A 

 small moth, apparently a tortricid, is reported to have become a pest of oranges 

 in Dominica through penetrating the skin and living and feeding in the pulp. 



The gunworni of the grape (Sciopteron regale), F. Maskew (Mo. Bui. Com. 

 Hort. Cal., 2 (1913), No. 10. pp. 677-679, figs. 2). — This paper presents descrip- 

 tions of the stages of a lepidopteran reared from grape twigs collected in the 

 Orient and intercepted at quarantine. 



The transmission of verruga by Phlebotomus, C. H. T. Townsend (Jour. 

 Amer. Med. Assoc., 61 (1913), No. 19, pp. 1717, 1718).— The author reports the 

 results of a preliminary transmission experiment in which 2 hairless dogs of 

 the species Cafiis caraiMcus were used. One cc. of serum containing the tritu- 

 rated bodies of 20 females of Phlebotomus verrucarum, a biting gnat occurring in
