Injurious insects of Ste. Anne's, season of 1909, J. M. Swaine (Ann. Rpt.

Insects which, damag'e saltbush, W. W. Froggatt (Agr Gas. N. S. Wales, 

 21 (1910). No. 6, pp. -'(65-^70. pi. 1, figs. 5). — The larvfe of several species of 

 moths, 2 weevils {Etwagna squamebunda and Bel us ursus n. sp.), and the salt- 

 bush scale {Pulvtnaria maskelli) are reported to be pests of this valuable 

 fodder plant. 



Some forest insects in the season of 1909, T. W. Fyles (.4?//?. Rpt. Quebec 

 8oc. Protec. Plants [etc.], 2 (1909-10), pp. 67-69). — The occurrence of Anisota 

 vlrginiensis, Datana angusii, Symmerista albifrons, and Schisura concinna is 

 noted. 



Observations on Termes g'estroi as affecting the Para rubber tree, and 

 methods to be employed against its ravages, H. C. Pratt (Dept. Agr. Fed. 

 Malay States Bui. 3, 1909, pp. 29, figs. 6). — A report of further studies of this 

 pest (E. S. R., 20, p. 764). 



Fourth annual report of the committee of control of the South African 

 Central Locust Bureau (Ann. Rpt. Coin. Control So. African Cent. Locust Bur., 

 4 (1910). pp. 59, pis. 2, maps 15). — The work carried on during the locust season 

 of 1909-10 is discussed and the reports received from members of the committee 

 of control on the locust conditions in their respective areas during this period, 

 together with reports from neighboring territories, are presented in full. The 

 minutes and proceedings of the fourth annual meeting of the committee of con- 

 trol, and maps showing the occurrence of the brown locust (Locusta pardalina= 

 Pachytylus sulcieolUs) and the red-winged locust (Cyrtocanthacris septemr 

 fasciata) from 1906 to 1910, are appended to the report. 



A synopsis of the Orthoptera of western Europe, N. Burr (London, 1910, 

 pp. 160; rev. in Nature [London]. 84 (1910), No. 2124, p. 3.9).— Short descrip- 

 tions of genera and species, tables of species under the genera, and the more 

 important naturalized species have been included in the work. 



The orchid thrips: Anaphothrips orchidaceus, R. S. Bagnall (Ent. Rec. 

 and Jour. Variation, 22 (1910). No. 12, p. 287). — The author finds that when In- 

 fested orchids blossom the adults and larvae leave the leaves and may be found 

 sheltered in numbers under the corollas, where by attacking the petals they 

 soon render the flowers unsightly and unmarketable. Because of its secluded 

 habits, ordinary fumigation is not effective in combating it. Periodically 

 cleaning the plants by picking up the adults and larvre with a camel's hair brush 

 and killing them by immersion in alcohol or other destructive agent is thought 

 to be the only safe method of dealing with it. 



The mosquito blight of tea, C. B. Antram (Indian Tea Assoc. [Pamphlet] 1, 

 1910, pp. V+W, pis. 2). — This is a report of studies made of the life history of 

 the so-called tea mosquito (Helopeltis tlieivora) and the results of a number of 

 remedial experiments conducted during the year 190S-9.
