that the locusts died from 4 to 6 days after being inoculated. The 

 best results were obtained in the presence of a nioderateh" moist sur- 

 rounding. In spreading the infection several methods may be adopted. 

 A number of locusts may be captured, dipped in a solution containing 

 the fungus, and then replaced in the swarm. Small areas of ground 

 frequently visited by the locust may l)o infected with the same solution. 

 For infecting the locust in the immature wingless stages, about a 

 pound of white bread was dried, pulverized and made into a rather 

 thick gruel; this mass was then inoculated with pure cultures of the 

 fungus, and after the fungus had developed so as to be readih" seen, 

 portions of the infected mass were placed in locations where the imma- 

 ture locusts might be likel}^ to feed.

 202-209). — Popular notes on Api>i dormta and on various iiractical matters connected 

 with bee keeping. 



Apiarian notes, J. P. Provan and H. G. Burxet {Jour. Janutica Agr. Soc, 4 

 {1900), Xo. 1, pp. 603-666). — The authors found that the amount of swarming was 

 consideraVjly reduced where 20 frames were allowed for each queen. The Italian 

 bees did not swarm as much as the dark hybrids, and the queens of the latter were 

 therefore killed off ami replace<l with Italian queens. 



The determination of sex in bees, Schiller-Tietz {FilJiJing's Landw. Ztg., 49 

 {1900), Nos. 18, x>p. 665-673; 19, pp. 715-717; 20, lyp. 755-760).— In this article the 

 author presents an elaborate discussion of the problem of the determination of sex in 

 the honeybee. The author does not accept in its entirety either the theory of 

 Dzierzon or that of Dickel, but inclines to the belief that the sex of the bees is already 

 determined in the egg at the time it is laid.

A list of the biting lice (Mallophaga) taken from birds and mammals of 

 North America, V. L. Kellogg {Proc. U. S. Xat. Mm., 22 {1900), pp. 39-100).— 

 The author presents an analytical table for the determination of species belonging to 

 this order of insects. The species are listed with bibliographical notes and indica- 

 tions of their hosts. The number of Mallophaga recorded from North American 

 host animals amounts to 282 species, of which 264 are from l)irds and 18 from mam- 

 mals. A list is also given of the host animals, with indications of the ]\Iallophaga 

 which occur upon each species. 



Report of the botanist and entomologist, G. ^V. Herrick {Mississippi Sta. 

 Ep>t. 1900 pjp. 40-42). — The liming of soil apparently had a benelicial effect in check- 

 ing the development of tomato blight. The author has undertaken work on insects 

 injurious to pecans. Experiments were conducted for the destruction of horn-fly. 

 Cattle were sprayed with mechanical mixtures of kerosene and water containing 10, 

 15 and 17 per cent. It was found that the flies were destroyed if the spray was 

 brought in contact with them. They frequently leave the back of the animal and 

 lie upon the belly, and it is tlierefore necessary to direct the spray accordingly.
