656 EXPERIMENT STATION RECORD. 



immature stages of the species Maine.stra yraitdis, M. adjtmcta, Xylina dis- 

 posita, Gluphisia severa, Petrophora ferrugata, and Gonodontis duaria. 



Upon the life cycle of Phylloxera quercus, B. Bonfigli (Atti R. Accad. 

 Lined, Rend. CI. .Sd. Fis., Mat. e Sat., 5. ser.. 11 (1908), II, No. 5, pp. 2J,8- 

 253). — In connection with this account the author gives three schemes which 

 graphically illustrate the life cycle. 



Notes on Trogoderma tarsale, C. O. Houghton (Jour. Eeon. Ent., 1 {1908), 

 No. 3, pp. 21G, 217). — The author records this species as developing to maturity 

 by subsisting upon dry hickory-nut shells. 



Saxon forest pest, C. B. Hukst (Dailii Consular and Trade Rpts. [U. S.], 

 1908, No. 3302, p. 11). — Caterpillars of the species Ocneria monaclia are reported 

 as very destructive to forests, particularly conifers, in one district of Saxony. 

 Distribution by railroad trains and destruction by attraction to light and by 

 hand picking of the moths by children are mentioned. 



Is it wise to dip nursery stock? F. H. Hall {New York State Sta. Bui. 302, 

 popular ed., pp. 2-4). — A popular edition of Bulletin 302 of the station pre- 

 viously noted (E. S. R.. 20, p. 256). 



Insecticide materials and their application, with suggestions for practice, 

 J. B. Smith {New Jersey Stas. Bui. 213, pp. S-J/G). — In this account the author 

 discusses spraying machinery, insecticides and their application in orchard prac- 

 tice, particularly as relating to the San Jose scale, codling moth, and plum 

 curculio. 



Analyses of Paris green and lead arsenate, C. S. Cathcart {Ncid Jersey 

 Stas. Bui. 21.'/, pp. 3-l-'i). — Analyses ai-e reported of 19 samples representing 17 

 brands of Paris green bought in the original packages and of 7 samples repre- 

 senting 6 brands bought in bulk. While the weights of the samples, as received 

 in their original packages, with one exception, equaled or exceeded the weights 

 claimed, there was a shortage in the actual weight of Paris green in 9 of the 

 19 samples ranging from 2.50 to 25 per cent with an average of 9.28. per cent. 

 All of these samples contained not less than 50 per cent of arsenious oxid com- 

 bined with copper as required by the New Jersey law, except one sample which 

 contained a large proportion of white arsenic. The average composition of the 

 samples analyzed was as follows: Total arsenious oxid, 57.14 per cent; water- 

 soluble arsenic compounds, 1.41 per cent; copper oxid, 29.38 per cent; and 

 arsenious oxid combined with copper, 54.94 per cent. 



Analyses of 15 samples of 9 brands of lead arsenate are reported and show 

 the following Aariation : Moisture, from 25.35 to 56.66 per cent; arsenic oxid, 

 from 4.21 to 20.48 per cent; lead oxid, from 16.07 to 44.32 per cent; water- 

 soluble arsenic, from 0.20 to 0.79 per cent. This large A-ariation is considered 

 as due to some extent to the evaporation of water after leaving the factory. 



On six new species of Ixodidae, including a second species of the new 

 genus Rhipicentor, W. F. Cooper, B. A. Cantab, and L. E. Robinson {Proc. 

 Camhridgc Phil. Soc., l-i {1908), No. 5, pp. -',57-470, figs. 2.}).— Descriptions 

 and illustrations are given of the six new species Amhlyomma longirostrum, 

 A. ecelaturum, Rhipieentor nuttalU, Aponomnia javanense, A. simplex, and 

 A. quadratum. 



On the habits, life cycle, and breeding places of the common house fly, 

 R. Newstead {Ann. Trap. Med. and Par., 1 {1908), No. 4, pp. 507-520, pis. 

 6). — A report is given of investigations carried on in the city of Liverpool 

 to ascertain the nature and extent of the breeding places of Musca domestica, 

 which appears to comprise 90 per cent of the flies there met with in the 

 houses. Examinations were made of various breeding places, an account of 

 which is given. Under the most favorable conditions, the flies develop in from 

 10 to 14 days. Suggestions as to remedies include the removal in summer
