Revision of tlie coleopterous family Bostrichidae, P. Lesne (Ann. Soc. Ent. 

 France, 78 {1909), No. J,, up. 471-57J,, pis. 5, fiffs. 92).— In this sixth memoir the 

 Dinapatinse and Apatinse are taken up. 



The root borer of sugar cane (Agr. News [Barbados'], 9 (1910), No. 204, 

 pp. 58, 59, figs. 3). — A brief accoimt is given of an atack in Barbados by this 

 root borer (Diaprepes ahhreviatus) , which was first noticed in December. 



A parasite on codling moth eggs, E. P. Tayloe (Nat. Hort., 2 (1910), No. //, 

 pp. 3, 4, fig. 1). — Observations made in the Grand Valley of Colorado during the 

 summer of 1910 show a large increase in the number of eggs of the codling 

 moth parasitized by Tricliogramma pretiosa. The first parasitized eggs were 

 noticed in orchards at Grand Junction on July 19. In counts made on August 

 2, 40 affected eggs were found to 3 normal ones. " Upon Lawver trees with only 

 scattering apples, which had consequently invited an abundance of codling moth 

 eggs, 170 eggs in all were counted, 154 of which were already showing signs of 

 parasitism, while 16 still appeared normal. This indicated only 9.4 per cent 

 of healthy eggs." 



The distribution of the large larch sawfly in Great Britain (Jour. Bd. Agr. 

 [London], 16 (1910), No. 12, pp. 981-991, figs. 3).— A report of an investigation 

 made in 1909 of the distribution of Nematus erichsonii in Great Britain. 



Bee keeping in Ontario, M. Pettit (Ontario Dept. Agr. Bui. 182, pp. 7). — 

 The information here summarized is based upon 488 replies received to ques- 

 tions sent to 2,175 bee keepers of Ontario. 



Honey, R. H. Millwaed (BtU. Intemat. Bur. Amer. Repuh. [English Sect.], 

 30 (1910), No. 2, pp. 229-246, figs. i3).— Information on the production of honey 

 in Latin America is included in this account. 



Cecidology in America, M. T. Cook (Bot. Gaz., 49 (1910), No. 3, pp. 219- 

 222). — A brief discussion of the subject. 



Ticks and tick-borne diseases, A. Theiler (Vet. Jour., 66 (1910), No. 416, 

 pp. 98-108). — Previously noted from another source (B. S. R., 23, p. 488). 



Experimental entomology, E. C. Cotton (Tennessee Sta. Rpt. 1909, pp. 

 105-107, figs. 2). — In the experimental work of the year, the life history studies 

 of the fever tick claimed the largest share of attention. " The outdoor incuba- 

 tion and seedtick longevity tests were continued and some valuable results were 

 obtained, confirming in a large measure previous conclusions. The patho- 

 genicity tests were also continued ; the lone star tick (AmUyomma americanum) 

 and the cayenne tick (A. cajennense) being the species studied." A description 

 is given of the refrigerating plant, constructed for studying ticks and insects 

 under constant low temperatures, a detailed account of which has been previ- 

 ously noted (E. S. R., 23, p. 657). 



The significance of the courtship and secondary sexual characters of 

 Araneads, T. H. Montgomeey, Jr. (Amer. Nat., 44 (1910), No. 519, pp. 151-

Analysis of Paris green, 1909, J. W. Kellogg (Penn. Dept. Agr. Bui 192, 

 p. 37).— Out of 500 samples of Paris green examined during the year, only 2 

 were found which contained less than 50 per cent of arsenic combined with 

 copper and 2 which contained more than 3i per cent of arsenic in water-soluble 

 forms. Many of the samples examined were found to be of better quality than 

 shown by their guaranties. 



A new insecticide, H. M. Leeoy (Agr. Jour. India, 5 (1910), No. 2, pp. 138- 

 143).— The author finds that in India lead chromate has certain advantages 

 over lead arsenate. It is easily made in paste form, is yellow and can be easily 

 seen on a sprayed plant, is extremely insoluble, does not decompose on a leaf,
