158 EXPERIMENT STATION RECORD. 



the zoology volumes of the International Catalogue of Scientific Literature, 

 annual issues 1 to 10, together with other names not included in previous 

 nomenclators. 



In the first volume it is estimated that the number of names in Scudder's 

 Nomenclator is about 80,000 to which were added some 40,000 in that index. 

 In the present volume some 22,000 names are I'ecorded, of which, however, an 

 uncertain number are due to erroneous readings. It is concluded that 140,000 

 names have been, up to the present time, proposed for the genera and subgenera 

 of zoological taxonomy. 



Plague eradication in Porto Rico, R. H. Creel {Jour. Amer. Med. Assoc, 

 60 (1913), No. 20, pp. 1527-1532, figs. 6).— In Porto Rico Mus norvegicus, M. 

 alexandrinus, and M. rattus infest houses, the first-named predominating. M.

LReport of] department of entomology, S. B. Doten (Nevada 8ta. Rpt. 

 1911, pp. 3J^-38). — The author presents a brief report of the work carried on 

 during the year. Investigations were made of an outbreak of a cutworm, which 

 proved to be Euxoa ridingsiana, which devastated alfalfa fields in the Monitor 

 Valley. 



Report of department of entomology, S. B. Doten (Nevada Sta. Rpt. 1912. 

 pp. 36-^0). — A brief statement of the work of the year with parasitic and 

 predaceous enemies of the codling moth, of observations of cutworms injurious 

 to alfalfa, of the European elm scale, etc. 



Report of the department of entomology (Oregon Sta. Bicn. Crop Pest and 

 Hort. Rpt. 1911-12, pp. 79-176, pis. 1,, figs. 70).— The first part of this report 

 consists of papers by H. F. Wilson on plant lice attacking orchard and bush 

 fruits in Oregon, the shot hole borer of the Northwest, or the pear blight beetle 

 of the East (Xylehorus dispar), the smaller shot hole borer (X. saxeseni), cod- 

 ling moth, San Jose scale, tent catei'piHars, cherry and pear -slug, some very 

 serious insect pests liable to be introduced into Oregon, and animals troublesome 

 in garden and orchard. Papers by A. L. Lovett deal with strawberry pests in 

 Oregon, the currant maggot or gooseberry fruit fly, the cabbage and radish 

 maggot (Phorhi-a hrassicce), and the garden slug (Limex agrcstis). Miscel- 

 laneous insect pests of orchard and garden are dealt with by H. F. Wilson 

 and A. L. Lovett. 



Check list of California insects, IV, C. W. Woodworth (Mo. Bui. Com. 

 Hort. Cat., 1 (1912), No. 13, pp. 9Jtl-9Ji8). — A continuation of the list previously 

 noted (E. S. R., 28, p. 155). 



Host index to California Coccidas, C. F. Baker and E. O. Essig (Mo. Bui. 

 Com. Hort. Cal., 1 (1912), No. 10, pp. 7//0-763).— This is a revision of the list 

 previously noted (E. S. R., 21, p. 757). 



The grape leafhopper, H. J. Quayle (Mo. Bui. Com. Hort. Cal., 2 (1913), 

 No. 3-^, pp. 375-3S2). — A general account of this insect, studies of which by 

 Johnson (E. S. R., 27, p. 758) and by Hartzell (E. S. R., 28, p. 855) have been 

 previously noted. 



In California the grape leafhopper occurs in greatest numbers in the San 

 Joaquin and Sacramento valleys. It also occurs in the coast valleys but is 

 seldom injurious there; and also in southern California, but south of the 

 Tehachapi it is most serious as a pest in the Imperial Valley. 



A few facts concerning the frait flies of the world, G. Compere (Mo. Bui. 

 Com. Hort. Cal., 1 (1912), Nos. 10, pp. 709-730, pi. 1, figs. 12; 11, pp. 8.',2-8Jt5; 

 12, pp. 907-911; 13, pp. 929-932, figs. 2). — A general discussion of the fruit flies 

 and their enemies, based upon the author's investigations in various parts of the 

 world, including Palestine, Egypt, Malta, Brazil, Australia, India, etc.
