preventives. Trapping in compost heaps especially in winter and by lanterns 

 in the spring is said to give good results. 



" Poisoned baits made of cotton-seed meal in which arsenate of lead or Paris 

 green has been incorporated furnish the most tempting baits for the mole 

 crickets. The baits can be scattered broadcast on the surface or covered If 

 animals that would likely eat the poison are allowed to run at large. Sulphur 

 distributed in the seed drill along with the seed acts as a repellent to a certain 

 extent. Naphthalin flalces placed near plants serve to repel the mole cricket, 

 but its injury to vegetation precludes its general use. Banding individual plants 

 by means of tin, paper, or wire cylinders will afford protection and is recom- 

 mended for tomatoes and plants of like nature." 



Thrips tabaci and its ravag-es in Hung'ary, E. Torok (Magyar Dohdnynjsag, 

 30 (1913), A'o. 1, pp. 6-9; abs. in Internat. Inst. Agr. [Rome^, Mo. Bui. Agr. 

 Intel, and Plant Diseases, Jf (1913), No. 3, pp. 493, .^9^).— This thrips, observed 

 for the first time in Hungary in 1890, has since spread with increasing rapidity. 

 In 1908 the author recorded the occurrence of this pest in 7 districts of the 

 country, 2 of which, Arad and Temes, had suffered considerably. While the 

 invasion in 1909 was less severe, due to the season being unfavorable to its 

 propagation, it now threatens to extend even to the eastern portion of Hungary.

 1). — A brief popular account. 



The oyster-shell scale (Lepidosaphes ulmi), F. Sherman, Jr. (Bui. N. C. 

 Dept. Agr., 34 (1913), No. 6, pp. 23, figs. 6). — A somewhat detailed account of 

 this pest with remedial measures therefor. 



The tent caterpillars, J. M. Swaine (Canada Expt. Farms, Div. Ent. Circ. 1, 

 1913, pp. l.'t, figs. 8). — This circular deals with Malacosoma americana and

The brown-tail moth, A. Vuillet (Rev. Phytopatli. Appl., 1 (1913), No. 2, 

 pp. 17-19, figs. J,; abs. in Rev. Appl. Ent., 1 (1913), Ser. A, pt. 8, pp. 270, 271).— 

 This is a discussion of the occurrence of the brown-tail moth in France. The 

 author states that there are 17 known dipterous and hymenopterous parasites 

 of this pest in Europe. 



The oak tortrix in Italy (Tortrix viridana), G. Cecconi (Bol. Lab. Zool. 

 Gen. e Agr. R. Scuola Sup. Agr. PortiH, 6 (1912), pp. 308-319, figs. 6; abs. in 

 Internat. Inst. Agr. [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 4 (1913), 

 No. 2, p. 327). — The larvae of this tortricid moth caused serious injury in 1911 

 and again in 1912. The present paper gives a description of the species, 

 biological notes, etc.

Babdophaga saliciperda damaging willows in Italy, G. Cecconi (Bol. Lab.

 3; abs. in Internat. Inst. Agr. [Rome], Mo. Bui. Agr. Intel, and Plant Diseases, 

 4 (1913), No. 2, p. 328). — The willow wood midge (R. saliciperda), recorded 

 from France, Austria, and Germany in 1841, was first recorded from Italy by 

 the author in 1910 on Salix alba. Outside of Italy this midge attacks other 

 species of willows and also Populus alba. The larvae tunnel into the wood of 

 the young trunks and branches. 



Several parasites of this pest have been reared by the author. Remedial 

 measures consist in covering the infected parts of the tree with a viscous sub-
