from apple, horse chestnut, hydrangea, jnaple, mulberry, wild cherry, and some 

 other hosts on Staten Island, N. Y.. by Doane. The author states that he has 

 also I'eceived the same species from various hosts in Maryland. A species from 

 citrus at Ojai, while very close to P. citri, is apparently distinct and most 

 closely i-esembles P. krannhice from Japan. 



Descriptions of P. pini, P. hromeliw, and P. i-lrgatua are given, together with 

 the synonymy of P. qurn-uK, Lnchnodius pJwradendri, and Cryptoripersia 

 nrtzonensis. 



Lac-producing' insects in the United States (Hemiptera; Coccidse), G. F. 

 Ferris {Jour. Econ. Ent., 12 (1919), No. 4, pp. 330-333).— A brief discussion of 

 (his subject, based upon a review of the literature and investigations conducted 

 in the Southwest during the course of a trip, reference to which has been 

 previously made (E. S. R., 41, p. 457). The author failed to find Tachurdia 

 larrecc to occur in sufiicieut quantity to be of commercial importance. 



Spray v. fumigation in the control of gray scale on citrus trees in Tulare 

 County, F. R. Brann {Mo. Bui. Cal. Com. Hart., 8 {1919), No. 3, pp. 104-107, 

 flff. 1). — A general discussion of the control of the gray citrus scale {Coccus 

 citricola [longulus]), in wliich attention is directed to the disadvantages of 

 spraying as compared with fumigation. It is said that fumigation with liquid 

 hydrocyanic acid gas has advantages over all other methods. 



On the use of the names Lachnus and Lachniella, A. C Baicer {Cnnad. 

 Ent., 51 {1919), No. 8-9, pp. 211-212). — The author finds Lachnus punctatus to 

 be the type for Lachnus, and Lachnu.^ fasciatus for Lachniella, and erects the 

 genus AVilsonia for Laoliniella gracilis of Wilson, 



Some observations on the webbing clothes moth (Tineola biselliella), M. T. 

 Smulyan {Psyche, 26 {1919), No. 3, pp. 71-73). — The data here presented sup- 

 plement the information given in the paper by Benedict, previously noted 

 (E. S. R., 38, p. 657), and confirm that author's conclusions that T. biselliella 

 rather than Tinea pellionella is the more common species in the North. 



Some recently recorded parasites of the oriental peach moth, L. A. Stearns 

 {Jour. Econ. Ent., 12 {1919), No. 4, pp. 3.^7, .?4S).— During investigations of this 

 pest in Virginia 11 parasites were reared, 7 of which have not been previously 

 recorded as attacking the oriental peach moth. 



Physiological and parasitological studies of economic Lepidoptera, C. 

 Gautier {Compt. Rend. Soc. Biol. [Paris], 82 {1919), No. 19, pp. 720-723).— 

 Continuing work previously noted (E. S. R., 41, p. 552), notes are presented 

 on Apanteles glomeratus and on the blood of a number of species of Lepidop- 

 tera. 



The striped skipper caterpillar of the coconut (Hidari irava), S. Leefmans 

 {Dept. Landb., Nijv. en Handel [Dutch East Indies], Medcd. Lab. Planten- 

 siekten, No. 35 {1919), pp. 15-31, i)ls. //). — Reports of damage by this cater- 

 pillar to coconut trees in Java, Sumatra, and Bali led to this study of Its life 

 history and parasites. 



The attack of the caterpillar results in the leaves being stripped up to the 

 big veins. From 8 to 9 days were found to be passed in the egg stage, from 

 32 to 37 as a caterpillar, and from 10 to 11 as pupa. Several parasites were 

 observed, of which a tachinid and a braconid were the only ones of importance. 

 As control measures, Paris green and lead arsenate are very efficient and do 

 not burn the leaves. 



New Jersey's work in mosquito control, W. E. Darnaix {Jour. Arner. Med. 

 Assoc. 73 {1919). No. 10, pp. 737-7 42, figs. 7).— This is an address delivered
