the authors.' experiments show to be easily infected with parasites of pernicious 

 and tertian malaria and much more so than all other species examined up to 

 the time of writing. Experiments' with the quartan type had not been concluded. 



A note on the flight of mosquitoes through horizontal water pipes, W. W. 

 King (Pub. Health Rpts. [U. 8.], 34 {1919), No. 9, pp. 3S6-390, fig. 1; Sci. Amer. 

 Sup., 87 {1919), No. 2255, p. 186).— The author's observations, conducted in St. 

 Thomas, Virgin Islands, with a species tliought to be Culex qidnqiiefasciatus 

 are summarized as follows: 



" Mosquitoes entered the left cisterns through unscreened perpendicular 

 waterspouts 2.5 and 3 in. in diameter and 14 and 10 ft. high. Mosquitoes did not 

 enter cisterns through larger unscreened waterspouts when these pipes had a 

 horizontal section from 12 to 32 ft. long. No observations were obtained of a 

 horizontal distance of less than 12 ft. 



" Mosquitoes bred in the cisterns and septic tank and having no other means 

 of exit passed through horizontal pipes 4 and 5 in. in diameter for a distance of 

 191 ft. in the longest instance, aided probably to a certain degree by air cur- 

 rents. No doubt they would pass through greater distances." 



Synopsis of the economic Syrphidas of Japan, S. Matsumura and .1. Adachi

New species of the economic Syrphidae of Japan, S. MATSUMtTRA {Jour. Col. 

 Agr. Hokkaido Imp. Univ., 8 {1918), No. 1, pp. 31, pi. 1). — Four genera are 

 erected and 54 species are described as new, in addition to those recognized in 

 the paper noted above. 



The biology of Dermatobia hominis observed in all its stages, A. Neiva 

 and J. F. Gomes {Ann. Paitlistas Med. e Cirurg., Sao Paulo, S {1917), No. 9, pp. 

 197-209, fig. 1; abs. in Rev. Appl. Ent., Ser. B, 7 {1919), No. 4, pp. 65, 66). —A re- 

 port of observations on the biology of this parasite at Sao Paulo. 



Anthrax: Transmission of infection by nonbiting flies, H. Mokeis {Louisi- 

 ana Stas. Bui. 168 {1919), pp. 3-12). — This is a report of experiments conducted 

 to determine the possibility of infection being carried to wounds of healthy 

 animals by flies which have fed upon or developed in anthrax-infected ma- 

 terial. The results of the work have been summarized by the author as 

 follows : 



" The house fly {Musca doniestica) and the blue bottle or green bottle flies 

 {Calliplwra erythrocephala, Lucilia cwsar, and L. sericata), are capable of 

 carrying anthrax infection to wounds on healthy animals, after having fed upon 

 anthrax-infected flesh. The house fly and the stable fly {Stomoxy» calcitrans) 

 are capable of carrying anthrax infection to wounds on healthy animals after 

 having fed upon the discharges from an open carbuncular swelling on an 

 animal sick with anthrax. Flies bred out of an unopened anthrax carcass 

 during the sunmier months in Louisiana do not carry anthrax Infection. The 

 results would indicate that flies bred in the presence of anthrax spores do 

 carry anthrax infection. The results would Indicate further that the vegeta- 

 tive form of anthrax in the unopened carcass is destroyed by the process of 

 decomposition." It is pointed out that the results prove the necessity for 

 prompt and complete destruction of all anthrax carcasses. 



The author's report of an investigation relating to anthrax transmission by 

 bloodsucking insects has been noted (E. S. R., 39, p. 161). 



A study of Compsilura concinnata, an imported tachinid parasite of the 

 gipsy moth and the brown-tail moth, J., J. Culvee {U. S. Dept. Agr. Bui. 766 

 {1919), pp. 27, pis. 2, figs. JO). — This is a report of investigations conducted, 

 with a review of the present status of knowledge of this important larviparous
