Statement concerning diseases of white grubs characterized by

(Third Ann. Rep. Direc. Kan. Univ. Exper. Station, 1893, 
p. 227.) 
Summary of an article by A. Giard* reporting his investigations 
of Isaria densa , a parasite of the European May beetle, together 
with mention of some other European parasites of insect larvae, 
including two bacterial species ( Bacillus septicus , Krass., and

Snow, F. H.—Contagious Diseases of the Cainch-bug. (Third 
Ann. Rep. Kan. Univ. Exper. Station, 1893.) 
Exhibits the results of experiments for the destruction of 
chinch-bugs by the artificial introduction of disease among live 
bugs in the field during the season of 1893. A list of all farmers 
from whom reports have been received is given, and, as far as 
possible, an extract is presented from each report giving the out¬ 
come of the experiment. States also results of scientific investi¬ 
gations in the University laboratory concerning the life history of 
the white fungus (Sporotrichum).
