ENTOMOLOGY. 261 



Onion cutworms, their ravages and treatment, F. H. Hall (New York State 

 Sta. />'»/. 120, popular ed., pp. 5, ph. 2). — A popular summary of Bulletin 120 of the 

 station (E. S. R., 9, p. 257). 



Phylloxera vastatrix in Sao Paulo, F. W. Dafekt (Iielat. Inst. Agron. Sao Paulo, 

 Brazil, 7-8 (1896), pp. 329-335).— This insect was discovered in Brazil in 1893 by 

 H. Potel. The report for 1894 of the commission formed for the study of the insect 

 is given. The conclusions drawn from the study are that the entire territory must 

 he considered as infested so as to further the work of destroying the pest. Govern- 

 mental action is not recommended. 



The raspberry cane maggot, M. V. Slingerland (Canadian Ent., 29 (1897), No. 7, 

 pp. 162, 163). — A technical description of the fly by D. W. Coqnillett, who gives it the 

 name Phorbia rubivora. 



The San Jose scale in Kentucky, II. Garland (Kentucky Sta. Bui. 67, pp. 43-59, 

 figs. .?). — The author discusses popularly the name and origin of this insect, its his- 

 tory in the United States, its food plants, the nature of its injury, methods of detec- 

 tion, and gives a brief description of it and its life history. The hydrocyanic-gas 

 method is described at length, and, briefly, the salt-lime-sulphur solution, kerosene 

 emulsion, and soap solutions. Legislation against the scale is recommended. 



The bill framed by the national convention of people interested in the matter at 

 Washington, March (5-7, 1897, is indorsed. 



The strawberry weevil, F. II. Chittenden (U. S. Dept. Agr., Division of Ento- 

 mology ('ire 21, 2. 8er., pp. 7, figs. 4). — The general appearance of the insect (Anthono- 

 mus signatus), its natural history and habits, distribution and injuries, and natural 

 enemies are discussed. The species of parasites thus far bred from it are said to be 

 Calyptus tibiator, Bracon anthonomi, Catolaccus anthonomi, and C. in cert us. The vari- 

 ous remedies which may be employed against the insect are (1) covering the beds 

 with line muslin; (2) since the insect feeds upon pollen, cultivation of pistillate 

 varieties of strawberries; (3) planting trap plants such as staininate varieties here 

 and there in the beds, or the red bud or bergamot, both of which may be of consid- 

 erable value as lures; (i) keeping the bed perfectly clean of wild or volunteer plants 

 and the burning over of the bed in spring. 



The remedies which have been tried and failed are noted, and as a repellant a" 

 spray of crude carbolic acid in 1 per cent solution is mentioned. Arsenical spraying 

 is thought scarcely advisable or practicable, although directions are given for it. 



The woolly aphis of the apple, C. L. Marlatt ( U. S. Dept. Agr., Division of 

 Entomology Circ. 20, 2. ser., pp. 6, figs. 2). — The general appearance of the insect is 

 described, its origin and distribution, natural history, and habits discussed, as well 

 as remedies and preventives recommended. Under the head of remedies and pre- 

 ventives, the experiments of J. M. Stedman demonstrating the value of tinely ground 

 tobacco dust as an insecticide are noted and the advice given not to inject carbon 

 bisulphid closer than 1$ feet from the crown of the tree. 



A few insect enemies of the orchard, C. P. Gillette (Colorado Sta. Bui. 38, 

 pp. 33-40, figs. 3). — Here are considered in a popular manner the San Jose scale 

 (Aspidiotus perniciosus), Putnam's scale ( Aspidiotus ancylus), Howard's scale (Aspid- 

 iotus howardi), the peach scale (Lecanium persicw), the brown or clover mite (Bryobia 

 pratensis), and the codling moth (Carpoeapsa pomonella) . The usual remedies against 

 them are recommended. 



Referring to the Paris green solution, it is stated that it has been found safe to use 

 the poison in the dry atmosphere of Colorado at the rate of 1 lb. to 160 gal. of water 

 instead of 1 lb. to 200 gal., usually recommended in Eastern States. The weaker 

 mixture, however, may be used for the second and third sprayings. 



Report of the entomological section, C. P. Gillette (Colorado Sta. Bpt. 1896, 

 pp. 143-147). — The author reports on the occurrence within the State of grasshop- 

 pers, leaf rollers, flat headed borers, cossid borers, San Jose" scale, codling moth 

 (Carpoeapsa pomonella), brown or clover mites (Bryobia pratensis), apple maggots 

 (Bhagoletis pomonella), striped cucumber beetle (Diabrotica vittata), red spiders
