ENTOMOLOGY. 1093 



Some observations on Antlieraea yamamai and the methods of its rearing 

 in Japan, C. Sasaki {linl. Col. Ayr., Tokyo Imp. Univ., 'J {1904), No. 1, pp. 43-50, 

 pis. 2). — Detailed notes are given on the habits, life history, and distribution of this 

 moth. It appears that the artificial rearing of the insect is practiced only by the 

 inhabitants of the village Ariakemura. The food plants of this moth are different 

 species of oak. 



A contribution to the life history of Orina tristis, T. A. CriAPArAN ( Trans. Ent. 

 Sac. London, 1903, pt. 3, pp. 24o-^Gl, ph. 3). — A detailed account is given of the 

 structure of the egg of this sj^ecies with especial reference to a hatching of the larva. 

 The habits of the adult insects are also described. 



New observations on phthiriosis of grapes, L. Mangin and P. Viala ( Compt. 

 Rend. Acad. Sci. Paris, 138 {1904), No. 8, pp. 529-531). — A continuation of the work 

 already carried on by the authors with regard to the cause and nature of this disease 

 indicates that the trouble is due to the attack of Dactylopius vitis which lives in sym- 

 biosis with the fungus Bornetina coriurn. 



On the wax-producing coccid Ericerus pela, C. Sasaki {Bxd. Col. Ayr., Tokyo 

 Imp. Univ., 6 {1904), No. 1, pp. 1-14, pfs. 2). — The literature relating to the produc- 

 tion of wax by scale insects is critically discussed, ^otes are given on the habits of 

 E. pela with special reference to its wax-producing powers. The insect is considered 

 to be a native of China and Japan.- The food plants differ in the two countries. In 

 Japan Fraxinus pubinervis is mentioned as one of the chief food plants of this scale 

 insect. F. chine^isis is an important food plant in China. 



Note on the habits of Chironomus sordidellus, T. H. Taylor {Trans. Ent. Soc. 

 London, 1903, pt. 4, pp. 521-523, Jigs. 2). — The habits of these aquatic larvpe are care- 

 fully described. In some cases it was observed that after pupation the six-legged 

 larva of a water mite was found attached to the body of Chironomus. The parasite, 

 however, ajipeared to have little injurious effect upon the host. 



An experimental study of hydrocyanic-acid gas as an insecticide, F. Lopez 

 {Bol. Sec. Fomento {Mexico'], 3 {1904), No. 11, IV-VI, pp. 203-2 15) .—Th.\s gas was 

 used in hospitals for the destruction of fleas, flies, mosquitoes, bedbugs, and other 

 insects. The toxic effect of the gas for such purposes is found to be very great and 

 satisfactory results were obtained in all experiments. 



Lime-salt-sulphur wash {Proc. Neiv Jersey State Hort. Soc, 29 {1904), PP- 61-76, 

 249-251). — The methods of preparing this wash and of applying it together with 

 details regarding the effects of the wash upon various scale insects and u^jon the 

 trees were discussed by J. B. Smith, AV. G. Johnson, and others. 



Spray calendar {New York Cornell Sta. Bid. 217, pp. 125-133, fig. 1). — In this 

 calendar the most important points regarding sprays have been arranged for the con- 

 venience of reference and use by fruit growers. A number of fruits and garden 

 vegetables are arranged in alphabetical order, the more important insect enemies 

 and fungus diseases are noted under each croi> with recommendations of the most 

 effective remedial treatment. 



Insecticides, R. Harcourt {Ontario Ayr. Col. and E.cpt. Farm lipt. 1903, pp. 43- 

 45). — Numerous samples of Paris green were analyzed for the purpose of deter- 

 mining the purity of the product and the relative insolubility of the arsenious acid. 

 Considerable percentage of the samples was found to be adulterated. Analyses are 

 also given of Black Death, potato bug finish, kno bug, slug shot, and Bug Death. 



The common mosquitoes of New Jersey, J. B. Smith {Neiu Jersey Stas. Bui. 

 171, }jp. 40, pis. 11, fiys. 6). — A detailed account is given of the habits, life history, 

 and anatomical characters of the various species of mosquitoes found in New Jersey. 



According to the author's investigations of this subject, 33 species of mosquitoes 

 occur in the State. Attention is called to the economic aspects of the mosquito 

 question, especially in regard to the agency of these insects in carrying malaria.
