The wild cochineal insect with reference to its injurious action on prickly 

 pear (Opuntia spp.) in India, etc., and to its availability for the subjuga- 

 tion of this plant in Queensland and elsewhere, H. Tryon (Queensland Agr. 

 Jour., 25 (1910), No. 4, PP- lSS-197). — A critical discussion of the subject. 



A contribution to the knowledge of Aleurochiton aceris, its host relations, 

 etc., M. Wolff (Centhl. Bakt. [etc.], 2. Abt., 26 (1910), No. 20-24, pp. 643-667, 

 pis. 2, figs. 17). — This paper deals with the morphology and biology of an 

 aleyrodid (A. aceris), which was the source of considerable injury to mapleS 

 (Acer platanoides) in the provinces of West Prussia and Posen in 1909. A 

 pteromalid parasite bred from the pupa is described as Urolepis schultzei n. sp. 



Notes on California Coccidae, V, E. O. Essig (Pomona Jour. Ent., 2 (1910) ^ 

 No. 2, pp. 209-222, figs. 14).— In this part (E. S. R., 23, p. 259) 9 species are

 Agr. Montpellier, n. ser„ 8 (1909), No. 4, pp. 292-319, figs. 9; 9 (1909), No. 1,

A contribution to the study of diseases of silkworms; Tricholyga sor- 

 billans in Cochin China, Broquet and Villeneuve (Bui. 8oc. Path. Exot., 3 

 (1910), No. 10, pp. 766-773). — This tachinid has been found to parasitize silk- 

 worms at Daii-Giai in the Province of Bien-hoa. The eggs are deposited upon 

 the silkworms, the larvfe hatching out within 24 hours and entering the body of 

 the host. 



The silkworm moth " rouge " in Cochin China, C. Broquet (Ann. Inst. 

 Pasteur, 24 (1910), No. 7, pp. 529-542, pi. 1). — The author here considers a dis- 

 ease of the silkworm moth that occurs in the region of Tan Chau, Cochin China, 

 and is due to a chromogenlc cocco-bacillus, which he calls " rouge." This 

 organism was isolated from the atmosphere at the sericultural station at Tan 

 Chau and from the humid surface of cocoons from which moths had emerged. 

 The loss caused, however, is not so great as that due to pebrine and to the 

 tachinid parasite Tricholyga grandis. 



List of Sphingidse of America north of Mexico, W. Barnes and J. McDuN- 

 NOUGH (Psyche, 77 (1910), No. 5, pp. 190-206). — Ninety-six species are listed
