tially upon soft or liquid animal food [e. g., Calosoma]. If they 
are of medium length, somewhat slender, broad at base and taper- 
ing distally, with the tip acute, and provided with basal processes 
which are not especially prominent or sharp, the food is chiefly 
animal, but solid structures are masticated and swallowed, and 
some vegetation appears in the alimentary canal [e. g., Chlænius]; 
while finally, if they are short and quadrate, blunt at the tips, and

The nature of the food taken by the Carabidæ is also much 
more varied than in the Coccinellidæ, the animal food including 
mollusks (slugs) and insects of all orders, while the vegetable 
food is composed of seeds (the graminaceous plants furnishing by 
far the greatest percentage), pollen and spores of lichens and 
fungi. Considering the 117 specimens which were dissected we 
find that, as a whole, their food consisted of fifty-seven per cent. 
of animal food and forty-three per cent. of vegetable food.
