 of years, presents a summary of the facts discovered and collected. 



Contributions to a knowledge of the Odonata of the Neotropical Region, 

 exclusive of Mexico and Central America, P. P. Calvert (A^vii. Carnegie Mus., 

 6 {1909), No. 1, pp. 73-280, pis. 9). — Two hundred and thirty-one species are

Termites and living plants, J. Chaine (Cotnpt. Rend. Soc. Biol. [Paris'], 

 68 il910). No. 22, pp. 1087, 1088; 69 (1910), No. 33, pp. U6-l't8) .—The fourth 

 article of this series (E. S. R., 24, p. 56) deals with the effect of the termites' 

 attack upon the plant, the fifth with the beginning of the invasion. 



Observations on nearctic Capsidae with descriptions of new species, O. M. 

 Eeutek (Acta Soc. Sci. Fermicce, 36 {1909), No. 2, pp. 86+III). — Descriptions 

 of a large number of new species are included in this account. 



On the life history of Trioza camphorse n. sp. of camphor tree and its 

 injuries, C. Sasaki {Jour. Col. Agr. Imp. Univ. Tokyo, 2 {1910), No. 5, pp. 

 277-286, pis. 2). — This psyllid occurs in swarms on camphor trees and is the 

 source of considerable injury through the falling off of infested leaves. It is 

 usually found on the camphor trees grown in the main island of Japan, Shikoku, 

 and Kiushu, as well as in Formosa, South China, etc. 



The characteristics and developmental history of the hemipterous fauna 

 of palearctic conifers, O. M. Reuter {Acta Soc. Sci. Fennicw, 36 {1909), No. 1, 

 pp. 129). — This work includes an annotated list of 304 species, and an extensive 

 bibliography of the literature relating to the Heteroptera, Auchenorrhynchia 

 and P.syllid8e on palearctic conifers. 



Interim report on froghoppers, F. W. Ukich {Bui. Dept. Agr. Trinidad, 

 9 {1910), No. 66, pp. 177-182). — This account of the natural Jiistory and methods 

 of control of froghoppers includes a bibliography of cane blight and froghoppers. 



Identification of the sugar cane froghopper, F. W. Urich {Proc. Agr. Soc. 

 Trinidad and Tobago, 10 {1910), No. 12, pp. 5.25-527).— It is stated that examina- 

 tions made by E. D. Ball have shown the sugar cane froghopper to be Tomaspis 

 varia. While T. postica was taken on sugar cane in Mexico, it is quite different 

 from the species injuring sugar cane in Trinidad. Three additional species of 

 Tomaspis are listed from the island. 



Notes on the biology of the froghopper, L. H. Gough {Bui. Dept. Agr. 

 Trinidad, 9 {1910), No. 66, pp. 17^-176).— A preliminary account of the life 

 history studies of the sugar cane froghopper. 



On spraying for froghoppers, L. H. Gough {Dept. Agr. [Trinidad], Circ. 

 5 [1910], pp. Jf, pi. 1). — The author finds that the control of the sugar cane 

 froghopper by means of sprays must be limited to fighting the adults as the 

 nymphs are protected by their froth or are underground and inaccessible. A 

 mechanically mixed kerosene and water solution is thought to be the most 

 effective spray. 



The froghopper fungus, J. B. Roreb {Bui. Dept. Agr. Trinidad, 9 {1910), 

 No. 66, pp. 182-184; aos. in Agr. News [Barbados], 9 {1910), No. 222, pp. 350, 

 351 ) . — ^A brief account of results of investigations of the entomophthorous fun- 

 gus that attacks the sugar cane froghopper. The fungus concerned is thought 

 to be a species of Oospora. 



The green muscardine of froghoppers, J. B. Roreb {Proc. Agr. Soc. Trini- 

 dad and Tobago, 10 {1910), No. 11, pp. 467-//82, pi. 1; abs. in Agr. News [Bar- 

 bados], 10 {1911), No. 230, p. 62).— The fungus that attacks the sugar cane 

 froghopper in Trinidad has been identified by R. Thaxter as Metarrhizium ani- 

 sopUce. It is said to be widely distributed and to attack a variety of insects
