ECONOMIC ZOOLOGY ENTOMOLOGY. ' 753 



Index-catalogue of medical and veterinary zoology, C. W. Stiles acd A. 

 Hassall (U. S. Dcpt. Agr., Bur. Auhn. Indus. Bui. 3D, pt. 36, pp. 2705-2706).— 

 This part consists of addenda and corrigenda to parts 1 to 35. 



Zoological record, D. Sharp (Zool. Rec, .'i6 {1909), pp. XII+lJiOJ,; J,! {1910), 

 pp. XII + l-'i06). — These volumes record the zoological literature relating chiefly 

 to the years 1900 and K»lo, re8])GCtively. 



Annual report of the entomologist for the year 1910-11, T. J. Anderson 

 (Dcpt. Agr. Brit. East Africa Ann. Rpt. 1910-11, pp. 161-171). — A brief account 

 is given of the work of the year, including notes on insects injurious to wheat, 

 coffee, and maize. 



Report of the work of the experiment station for the years 1905 and 

 1906 on the destruction of the San Jose scale, etc., J. 11. Stewart (West 

 Virginia t^ta. Rpt. San Jose Scale, etc., 1905-6, pp. 39, pis. 8). — This is a report 

 of the work of the station under a state law for the destruction of the San 

 Jose scale and other dangerous insects, etc., daring the year ended September 

 30, 1906. It contains a reiwrt of the entomological department by W. E. 

 Rumsey and F. E. Brooks (pp. 9-26), which discusses nursery inspection work, 

 the occurrence of San Jose scale in the State, and experiments with insecticides, 

 and gives notes on other important insects of the year, including the codling 

 motli, plum curculio, fall webworm, periodical cicada, rose chafer, woolly apple 

 aphis, the greater chestnut weevil (Balamnus prohoscidcus) , the lesser chest- 

 nut weevil, shot-hole borer, the catalpa sphinx, grape curculio, and scurfy scale, 

 and a report of the bacteriologist noted on page 746 of this issue. 



Insect notes for 1911, O. A. Johannsen and Edith M. Patch (Maine Sta. 

 Bui. 195, pp. 229-2-'f8, pis. 2). — Tests were made of various methods which have 

 been recommended for the extermination of wareworms in corn. " TTie poisons 

 and repellents used, usually so successful in combating insects under other 

 conditions, were not efficient against wireworms in our tests. The successful 

 growth of the peas leads one to believe that a rotation involving peas, or pos- 

 sibly peas and oats, a common fodder crop in this State, or clover, may be 

 effectively employed, though whether wireworms are thereby actually reduced 

 in number in the field so they may be less injurious u^ion susceptible crops 

 planted later, future experiments alone will decide." 



Among some of the more important insects mentioned are Haltica cariaata, 

 which attacked elms at Orono; the poplar weevil {Cryptorliijnchus lapathi), 

 which is a serious pest in some localities; the bean maggot {PhorMa fusciceps), 

 which was reported to be the source of damage to young plants in various parts 

 of the State; the apple maggot, which continues to be the most serious dip- 

 terous pest in the State; the brown-tail moth, which in many localities fed 

 sufficiently upon the apple to be troublesome at picking and to destroy the 

 foliage to a con.siderable extent; the spruce bud moth {Tortrix fuinifcrana), 

 whicli occurred in alarming numbers; Monodontoinerus ccrcus, a parasite of 

 the brown-tail moth imported from Europe, which has gradually been spreading 

 in Massachusetts and was discovered in Maine for the first time; etc. 



An account of Pemphigus tessellata (acerifolii) on alder and maple, by 

 Edith M. Patch is appended. Observations subsequent to those previously 

 noted (E. S. R., 20, p. 856) are said to confirm the previous evidence and leave 

 no room for doubt that the alder and maple represent 2 hosts of a single 

 species, the alder being the summer home of the progeny of the migrants from 

 the maple. It is not a simple case of alternate hosts, for the alder besides 

 serving for summer host for the progeny of the maple migrants maintains a 

 continuous series of apterous, viviparous, parthenogeuetic females. 



How contact insecticides kill, G. D. Shafer {Michigan Sta. Tech, Bui. 11, 

 pp. 65, pis. 2, figs. 7). — This bulletin consists of 2 parts, the first of which (pp.
