GROUND BEETLES ATTACKING 
CROPS IN’ MYSsORi. 
—<———— 
SEVERAL species of ground beetles of the genus Gonoce- 
phalum (Opatrum) have been recorded from various parts 
of the world as more or less injurious to crops. O. sa- 
bulosum' has been found to attack vines, in France, and 
tobacco and maize, in parts of Russia. In Rhodesia and 
Nyasaland, G. sintplex” is looked upon as a pest of tobac- 
co. Lindeman has described in some detail G. interme- 
dium’ (Fisch) which he reports as doing serious damage to 
tobacco and seed-corn, while Miss Ormerod in her ‘ Injur- 
ious Insects in South Africa’, p. 19, gives O. micans’ asan 
injurious species. Koningsberger’ reported O. depressum 
as probably domg damage to roots of various plants in 
Java as long ago as 1898. Later he substantiated this 
and noted that besides the damage done by the larvee on 
tobacco in nurseries, the adults, at) times, injure tobacco 
in the field by gnawing the stems at or below the surface
