254 EXPERIMENT STATION RECORD. 



The pocket gopher, T. H. Scheffer {Kansas Sta. Bui. 172, pp. 197-233, figs. 

 IJf). — This is a revision of Bulletin 152, previously noted (E. S. R., 19, p. 1156). 



Catalogue of Canadian birds, J. and J. M. Macoun {Ottawa: Oeol. Survey 

 Canada, 1909, pp. VI+761+XVIII).— In the present edition (B. S. R., 16, 

 p. 543) much of the matter has been rewritten, many additional facts recorded, 

 and the whole combined into one volume. 



In compiling the catalogue, the authors have attempted to bring together facts 

 on the range and nesting habits of all bii'ds known to reside in, migrate to or 

 visit, the northern part of the continent. In addition to the Dominion of Can- 

 ada they have included Newfoundland, Greenland, and Alaska. The nomen- 

 clature and the numbers given in the latest edition and supplements of the 

 A. O. U. check-list published have been made the basis of arrangement. 



A manual of Philippine birds, R. C. McGregor {Manila: Bur. ScL, 1909, 

 pt. 2, pp. XVI-{-Ji31-769). — This second part of the work previously noted 

 (E. S. R., 22, p. 353) takes up the order Passeriformes. It is stated that this 

 order includes nearly as many species, among Philippine birds, as all the other 

 orders combined. 



Zoological yearbook, 1909, P. Mayer {Zool. Jahresber., 1909, pp. VIII + 

 247+33). — Bibliographical lists are given and summaries of the more impor- 

 tant literature issued during 1909 relating to the various groups of the animal 

 kingdom. 



Report of the International Commission on Zoological Nomenclature, 

 C. W. Stiles {Science, n. sen, 82 {1910), No. 830, pp. 76^-767).— This brief re- 

 port includes by-laws adopted by the Commission and amendments to the inter- 

 national rules of zoological nomenclature recommended to the Congress. 



Report of the entomologists, C. H. and H. T. Fernald and J. N. Summers 

 {Massachusetts Sta. Rpt. 1909, pt. 1, pp. 73-76). — A brief account is given of 

 the progress of investigations under way. 



It is stated that the experiments for the control of the onion thrips have 

 proceeded far enough to show that spraying the onions after this pest has 

 appeared on them is, at best, only a partial remedy. "A study of the life 

 history of these insects shows that they pass the winter at the top of the 

 ground in protected places, such as are furnished by dead grass around the 

 onion fields, in rubbish heaps and similar places; and a few attempts to de- 

 stroy them by burning over the grass and rubbish around the fields have been 

 followed by a reduction in the abundance of the insect the next spring." 



In speaking of the influence of climatic conditions upon the northern distri- 

 bution of several injurious insects, it is said that for at least one the limits 

 will probably be found within the State. The evidence now available " sug- 

 gests the belief that in Massachusetts the elm-leaf beetle will not be likely to 

 be of much importance in those parts of the State that are more than a 

 thousand feet above sea level, except perhaps, in the southern edge of the State, 

 where the altitude is to some extent offset by the more southern latitude." 



Insects of the year, H. T. Fernald {Massachusetts Sta. Rpt. 1909, pt. 2, 

 pp. 70-73). — ^A brief report of the more abundant insect pests of 1909. 



An outline is given of the history in Massachusetts of the elm-leaf beetle, 

 which for several years has been increasing in abundance and attracting more 

 attention. The San Jose scale is becoming more abundant in orchards and on 

 ornamental shrubs and trees and in some cases is found in wooded areas. The 

 leopard moth {Zeuzcra pyrina) which has increased in abundance in the region 

 around Boston is another menace to shade trees. The gipsy moth has also 

 increased and the brown-tail moth is spreading in the State, nests having been 

 found as far west as Brookfield and Belchertown. The 12-spotted asparagus 

 beetle {Crioceris 12-punctata) has been found fairly abundant at Concord and
