scratched skiu of mules for about 5 minutes, show that T. hippicum may be 

 thus transmitted. It is stated that no new cases of murrina have been detected 

 in the Canal Zone since May, 1910. 



The percentage and quality of hides injured by the ox warble in the 

 reg-ion of Lyon, N. Lehmann and C. Vaney {Compt. Rend. Acad. Sci. [Parish, 

 15.i (lOlJ), Xo. 20, pp. 13. ',3-13 1,5 ; abs. in Jour. Roy. Micros. Soc. [Londoti], 

 1911, Xo. 5, p. 619). — In observations made at Lyon extending throughout 1908, 

 1909, and 1910, warbles were found in hides in every month, but from Septem- 

 ber to March inclusive they were either retarded larvfe beginning to degenerate 

 or only larval remains. From March to June, when there are no living adults, 

 there is a growing percentage of larvae in the skin. This fact can only be ex- 

 plained as due to a migration from the viscera. The penetration of the larvae 

 from the alimentary tract is supiwrted by the following facts: "(1) The winter 

 restriction of the very young larvae to the submucosa of the anterior portion 

 of the alimentary canal; (2) the growth of the larvae in the esophageal region; 

 (3) the occurrence in February and March of more developed larvae in the 

 membrane of the spinal cord and in the subcutaneous tissue of unperforated 

 skiu; (4) the increasing abundance of sedentary larvae in the skin from May 

 to July," 



The authors find that while bullocks with thin skins show a greater percent- 

 age of warbles present, it is the opposite with cows. This leads them to con- 

 clude that there is no relation between the skin thickness and the percentage 

 of infestation. 



The relation of weather conditions to the frequency of ox warbles, N. Leh- 

 mann and C. Vaney {Compt. Rend. Acad. Sci. [Paris], 152 {1911), No. 22, 

 pp. 1508-1510). — The authors find that in the region of Lyon warm, dry 

 weather during July and August favors oviposition and is followed by a high 

 percentage of warbled hides the following year. 



The species of Brachyacantha of North and South America, C. W. Leng 

 {Bill. Amer. Mus. Xat. Hist., 30 {1911), pp. 279-333, pi 1, figs. 4.5).— Thirty- 

 three species and 11 varieties of coccinellids of this genus are described, of 

 which 6 siiecies and 6 varieties are new to science. 



The wild passion-fi'uit weevil (CEmethylus triangularis), W. W. Froggatt 

 {Agr. Gas. X. S. Wales, 22 {1911), Xo. 10, pp. 910, 911, pi. i).— This weevil has 

 been found infesting the fruits of the wild passion-vine {Passiflora Herbert iana) 

 over a very large area. Its range is thought to be that of its food plant, which 

 grows in Australia throughout the semitropical scrubs, trailing over low scrub 

 trees. 



A comparative study of four digestive ferments in some species of Coleop- 

 tera, L. Bounouee (Compt. Rend. Acad. Sci. [Paris], 152 {1911), Xo. I,, pp. 

 228-231; abs. in Jour. Roy. Micros. Soc. [London], 1911, Xo. 5, p. 619).— A study 

 of the digestive ferments of Dytiscus vmrginalis, Rydrophilus piceus, Geotrupes 

 sylvaticus, Melolontha vulgaris, and Polyphylla fiiUo. 



A contribution toward the life history of Emphor bombiformis, J. A. 

 Grossbeck {Jour. N. Y. Ent. Soc, 19 {1911), Xo. J,, pp. 238-21,',, pi. 1, figs. 2).— 

 Studies of the biology of one of the larger digger bees are here reported. 



A hymenopterous parasite of the bee moth, A. Conte {Compt. Rend. Acad. 

 Sci. [Pans], 15J, {1912), Xo. 1, pp. 1,1, 1,2). — Two hymenopterous parasites of 

 the bee moth, Galleria meUonella {cereana), have been recorded, one the 

 chalcidid Eupelmus cereanus by Rondani in Italy, the other Bracon brevicornis 

 by Marshall in France. The author here reports having observed a third 

 species, Apanteles lateralis, to be very abundant in the vicinity of Lyon and 

 apparently of considerable importance, since it has been reported to attack 

 the larvae of several moths in England and Germany, including Eupithecia,
