250 EXPEKIMENT STATION RECORD. [Vol.43 



Pinus exceUa, P. flexilis, P. koraiensls, P. cembra, P. densiflora, P. austriaca, 

 P. resinosa, ami P. sylvestris were inoculated without success. No iufectious 

 developed beyond the pycnial stage upon any species except P. strobus, 

 although early stages of infection have been secured upon P. lambertiana 

 and the two pitch pines, P. pinea and P. sabinianu. Tests have not yet been 

 made with the pinon pines, P. ed^ilis and P. monophyUa. Details of these 

 expei'iments have, in part, been publislied previously (E. S. R., 42, p. 247). 



ECONOMIC ZOOLOGY— ENTOMOLOGY. 



The zoological record, D. Sharp (Zool. Rec, 52 {1915), pp. y/ + [7i3]; 

 5S {1916), pp. /F+[6S7]; 54 {1911), pp. 7^+ [590]). —These catalogues, which 

 are in continuation of those previously noted (E. S. It., 36, p. 151), index the 

 literature in the main part for the years 1915, 1916, and 1917, respectively, but 

 include also entries for earlier years that were received too late for inclusion 

 in the respective volumes. 



Control of the coyote in California, J. Dixon {California St a. Bui. 320 

 (1920), pp. 379-397, fiffs. 7). — A brief account is first given of the habits of the 

 coyote, particularly as relates to means of control. The methods of destruction 

 are then considered under the headings of trapping, poisoning with strychnine, 

 digging out dens containing young, and shooting. 



Rats and mice as enemies of mankind, M. A. C. Hinton {Brit. Mils. {Nat. 

 Hist.), Econ. Ser., No. 8 {1918), pp. X+63, pis. 2, figs. 6).— The several parts of 

 this paper deal with rats, house mice, the balance of nature, and the protec- 

 tion of Carnivora, and the structure and classification of the Murida?, with 

 a key to British species. A table showing the rate of increase in rat i)opu- 

 • lation possible in 1918 and a list of 18 references to the literature are also 

 given. 



A synoptical list of the Accipitres (diurnal birds of prey) , H. K. Swann 

 {London: John Whcldon d Co., 1919, pt. 1, pp. 38; pt. 2, pp. .39-74).— Part 1 of 

 this list of the diurnal birds of prey deals with Sarcorhamphus to Accipiter; 

 part 2 with Erythrotriorchis to Lophotetus. 



Contribution to the knowledge of the biology of the arvicole in Apulia, 

 G. Maktelli {Bol. Lab. Zool. Gen. e Ayr. R. Scuola Super. Ayr. Portici, 13 

 {1919), pp. 193-316, flys. 32). — This is a report of studies of meadow mice and 

 means for their control in Apulia, Italy, where they are the source of consider- 

 able loss. 



Birds and tent caterpillars, A. A. Saunders {Auk, 37 {1920), No. 2, pp. 312, 

 313). — The author reports observations made at Norwalk, Conn., during the 

 spring of 1917, which indicate that the tent caterpillars were destroyed while 

 small by insectivorous migrant birds, the arrival of the birds being coincident 

 with the disappearance of the tent caterpillar. Their attack of the tent 

 caterpillar may have been due to the scarcity of other insect food during the 

 spring, which was late and cold. A parula warbler {Gompsothlypis americana 

 vsncce) and a yellow-brea.sted chat {Icteria rirens virens) were actually 

 observed in the act of eating the caterpillars. Numerous empty nests, with 

 holes such as a bird would make with its beak, furnished evidence that the 

 birds had destroyed the half -grown caterpillars in this way. 



Second note on certain peculiar fungus-parasites of living insects, R. 

 Thaxter {Bot. Gas., 69 {1920), No. 1, pp. 27, pis. 5).— This continuation of the 

 work previously noted (E. S. R., 33, p. 556) includes descriptions of 6 genera 

 and 13 species new to science. 



Nineteenth report of the State entomologist for 1919, W. E. Bkitton 

 {Connecticut State Sta. Bui. 218 {1919), pp. 113-208, pis. 24, figs. 5).— The tirst
