r.acillus, by S. Rowland (pp. ll-IJ)) ; and Observations on the Breeding of llvs 

 rattus in Captivity dip. l!)3-206). 



A book on birds, A. W. Bombkruicr {rjiihidclphia, ID 12, pi). VII +209, pis. 

 33). — This is a popular account. 



The birds of Guiana, F. P. and A. P. Penard {Dc Yogels van Guyana. 

 The Hague, 1910, vol. 2, pp. 587, figs. 122). — This second part (E. S. R., 23, p. 

 DHii) deals with the orders Picaria; and Passeres. 



Studies of bird life in Uganda, R. A. L. and V. G. L. van Someren {London, 

 1911, pp. 22, pis. 25). — Accounts are given, together with plates, of 25 of the 

 land and water fowl of Uganda. 



Report of entomological section, C. P. Gillette {Colorado ^ia. Rpt. 1910, 

 pp. 98, 99). — Observations have been made upon the migratory habits of Aphis 

 cornifolUe, which leaves the dogwood, Svida {Conius) sfolonifcra riparia, in the 

 spring and takes up its abode chiefly upon the sunflower (Helianthus) leaves, 

 and then sends return migrants from the sunflowers to dogwood again in the 

 fall. A. helianthi and A. gillcttci are deemed almost certainly synonymous with 

 A. cornifolke. 



A new corn root worm, Diabrotica virgifcra, and its variety filicomis, have 

 done serious injury in limited localities in Colorado for the past 2 years. 



Report of entomologist, A. F. Conradi {South Carolina Sfa. Rpt. 1911, pp. 

 52-60). — In experimental spraying work carried on in several sections of the 

 State during the year with the cottony maple scale and the gloomy scale, lime- 

 sulphur applied in December satisfactorily controlled the gloomy scale but, like 

 kerosene emulsion, had no appreciable effect on the cottony maple scale. Sum- 

 mer sprays of caustic potash whale-oil soap at the rate of 1 : 4 were beneficial 

 against the cottony maple scale. 



The use of Phinotas oil in springs infested by crawfish resulted in the de- 

 struction of the pest. 



Life histories of Indian insects. — III, The rhinoceros beetle (Oryctes 

 rhinoceros) and the red or palm weevil (Rhynchophorus ferrugineus), C. C. 

 Ghosh {Mem. Dept. Agr. India, Ent. 8cr., 2 {1911), No. 10, pp. 193-217, pis. 

 //). — This paper deals with the rhinoceros beetle (0. rhinoceros) and the red 

 or red palm weevil {R. ferrugineus) , both of which are very destructive to 

 palm trees, especially in southern India, the damage being done by the former 

 as a perfect beetle and by the latter as a larva. 



Some important insects of Illinois shade trees and shrubs, S. A. Forbes 

 (Illinois Sta. liul. 151, pp. Jf63-529, figs. 67). — This is a popular account of 

 some 2.5 of the more important insect enemies of trees and shrubs in Illinois. 



The possible etiological relation of certain biting insects to the spread of 

 infantile paralysis, C. T. Brues and P. A. E. Sheppard {Mo. Bui. Bd. Health 

 Mass., n. ser., 6 {1911), No. 12, pp. 338-3//0).— This is a brief account of in- 

 vestigations conducted from July 30 to September 26, 1911, in which the homes 

 of 88 patients in 17 cities and to-mas were investigated as to the presence of 

 biting flies and insects in close proximity to affected individuals. 



" Nothing absolutely definite has hitherto been ascertained regarding the 

 chamiels of infection of acute epidemic iwliomyelitis. Many facts connected 

 with the distribution of cases and the spread of epidemics of this disease, 

 together with histories of insect bites, suggest at least that the disease may be 

 insect-borne. From our field work during the present summer, together with 

 a consideration of the epidemiology of the disease, it has been suggested that 

 Stomoxys calcitrans may be responsible for the spread of acute epidemic polio- 

 myelitis. No facts which disprove such hypothesis have as yet been adduced. 

 Experiments based upon this hypothesis are now in progress."
