58 EXPERIMENT STATION RECORD. 



botrana, conducted iu French vineyards during 1909, in which the periods most 

 favorable for the application of insecticides were determined. 



Some common bagworms and basketworms, C. Fuller {Natal Dept. Agr. 

 Bui. 16, pp. 11, pis. 3, figs. 14). — In this paper particular attention is given to 

 the wattle bagworm. 



The brown-tail moth, in Canada, C. G. Hewitt {Canad. Forestry Jour., G 

 {1910), No. 2, pp. .'fS, Jf.'f). — During the inspection of European nursery stock in 

 1909, over a million and a half plants were examined and nearly 200 winter 

 webs were found. During the season of 1910 over 300 webs were found on 

 some 2,000,000 plants inspected. 



Crossing of the silkworms, with reference to Mendel's law of heredity, 

 S. ISHiwATA {Bui. Assoc. Scri. Japon, 1910, No. 215, pp. IS). — In the experi- 

 ments here reported, the color of the cocoon, marking of the worm, and the 

 number of molts were considered. 



The race which spun cocoons of the yellow color was found to be dominant in 

 this respect over those which spun green and those which spun white cocoons, and 

 the green was dominant over the white. In the first generation of crossing 

 between 3-molt and 4-molt races, the worms became mature after the third 

 ecdysis. In the second generation both 3-molt and 4-molt worms were produced, 

 thus showing that the 3-molt habit is dominant over the 4 molt. 



On the silk fish line, C. Sasaki {Jour. Col. Agr. Imp. Univ. Tokyo, 2 {1910), 

 No. 2, pp. 163-181, pis. 3). — The silk fish line here considered, commonly called 

 " tegusu " by the Japanese, is largely employed by fishermen in all parts of 

 Japan. It is not prepared in that country, however, a large quantity being an- 

 nually imported from southern China. The author has determined that the 

 worms producing the silk used are the larvse of Satiirnia pyretorum. Descrip- 

 tions are given of the several stages in the life of this species and of the meth- 

 ods of raising the larvre and of preparing the fish lines in Hainan Island. 

 Cocoons were introduced into Formosa from South China during 1908. 



Annual report of the Tasar Silk Rearing Station, Chaibassa, Bengal, for 

 the year 1907-8, F. Smith {Ann. Rpt. Tasar Silk Rearing Sta., Chaibassa, 

 Bengal, 1907-8, pp. 11, pis. 2). — This is the first report that has been issued in 

 regard to this station which was opened in 1906. 



Annual report of the Chaibassa Tasar Silk Rearing Station for the year 

 1908-9, F. Smith {Ann. Rpt. Tasar Silk Rearing Sta., Chaibassa, Bengal, 

 1908-9, pp. llf, pis. 3). — This, the second annual report, covers the period from 

 April 1, 1908, to June 30, 1909. 



Annual report of the Royal Sericultural Station, Padua {Ann. R. Staz. 

 Bacol. Padova, 36 {1909), pp. 112, pis. 2, fig. 1). — This report includes a number 

 of papers relating to the silkworm and silk culture. A list, prepared by 

 E, Bisson, is given of the publications related to sericulture that were issued 

 during 1907-8. 



The Hessian fly in Illinois, 1910, S. A. Forbes {Illinois Sta. Circ. 1^6, pp. 

 Jf). — During 1910 the wheat crop in Illinois was injured by the Hessian fly to 

 a total of several millions of dollars — over $600,000 in one county, according 

 to conservative estimates. In view of the probability that iu 1911 the infesta- 

 tion will be larger than usual, the author has prepared and here presents 

 briefly information as to the most approved methods of preventing its injuries. 



Gall midges of Aster, Carya, Quercus, and Salix, E. P. Felt {Jour. Econ. 

 Ent., 3 {1910), No. //. pp. 3-^7-356). — Tables are given for the separation of 

 species reared from asters, hickories, oaks, and willows. Nineteen occur upon 

 Aster, 17 upon Carya. 21 upon Quercus, and 46 upon Salix. 



Papers on cereal and forage insects. — The smoky crane-fly (Tipula in- 

 fuscata), J. A. Hyslop {U. S. Dept. Agr., Bur. Ent. Bui. 85, pt. 7, pp. 119-132,
