quitoes, or other insects, are possible modes of spread of tlie disease; but sucli 

 infection, if it ever does talj;e place, is accidental and exceptionaL Having 

 found acid-fast bacilli answering as far as our imperfect tests permit to the 

 characteristics of lepra bacilli in a considerable proportion (about 30 per cent) 

 of specimens of Acanthia lectularia up to 16 days after feeding on lepers, there 

 is reason to believe that this species of insect constitutes a very important agent 

 in the spreading of leprosy."

 Fruit, 6 (1912), No. 8, pp. 21-26, 73-75, figs. 11). — The data here presented

The present state of the knowledg'e of foul brood in bees, S. Korolev ( Viest- 

 nik Bakt. Agron. Stantsii V. K. Ferrein, 19lO, No. 17, pp. 30-99; J911, No. 18,

Ichneumonids and tachinids as intermediate hosts of Chlamydozoa, Wolff 

 (Mitt. Kaiser Wilhelms Inst. Landw. Bromberg, 3 (1910), No. 1, pp. J,9, 50).— 

 The author repoi'ts having found the yellow disease or jaundice (grasserie) in 

 jjupte, princiijally of Bupalus piniarius, received from West Prussia. Attention 

 is called to the fact that the virus from Chlamydozoa carriers (ichneumonids 

 and tachinids) will infect the caterpillar of the nonne moth, when inoculated, 

 and that this will take place even after months of drying. 



Some North American Cynipidse and their g-alls, W. Beutenmijller (Bui. 

 Amer. Mas. Nat. Hist., 26 (1909), pp. 277-281, pi. 1; 28 (1910), pp. 117-136, 

 137-lU, 253-258, pis. 10; 30 (1911), pp. 3-'i3-369, pis. 6).— These jjapers, which 

 constitute the sixth to tenth of a series of articles by the author on North 

 American Cynipidae and their galls (E. S. R., 22. p. 255), deal with the genera 

 Eumayria, Belenocnema. Solenozopheria, and Compsodryoenus ; Neuroterus; 

 Aylax ; Aulacidea ; and Dryophaiita, res]iectively. 



The transmission of typhus fever, with especial reference to transmission 

 by the head louse (Pediculus capitis), J. Goldberger and J. F. Anderson (Pub. 

 Health and Mar. Hasp. Serr. V. H., Pub. Health Rpts., 27 (1912), No. 9, pp. 

 297-307, figs. 6). — Exi^erimeuts conducted with the body louse and head louse, 

 here reported, have led the authors to conclude that the body louse (P. vesti- 

 menti) and the head louse (P. capitis) may become infected with typhus. The 

 virus is contained in the body of the infected louse and is transmissible by sub- 

 cutaneous injection of the crushed insect. It may also be transmitted by the 

 liite of the body louse, and. it is believed, by that of the head louse as well. 



Papers on deciduous fruit insects and insecticides. — Notes on the peach 

 bud mite, an enemy of peach nursery stock, A. L. Quaintance (U. 8. Dept. 

 Agr., Bur. Ent. Bui. 97, pt. 6, pp. 103-11. 'f, pis. 5). — " For the past 15 or 20 years 

 nurserymen in the East have complained of a well-defined trouble of peach 

 nursery stock, resulting from injury to the tender terminal bud of the prin- 

 cipal shoot. The injury causes the cessation of further upward growth of 

 the shoot and results in the development from the lateral buds of numerous 

 branches, a condition very objectionable in stock of this class where a single 

 vigorous shoot is desired. There have been several references in literature to
