and in the morning appeared, like Oliver Twist, to be ask¬ 
ing for more. 
Calosoma calidum is neither as large nor as beautiful as 
its cousin, the scrutator, but it is more abundant, and will 
often be seen during the warm evenings of June, scurrying 
away from his feast under the electric lights when dis¬ 
turbed by the passer-by. He is a somewhat striking beetle, 
being quick and graceful in his movements and having 
rather pretty markings, his elytra being a deep brownish- 
black, with six longitudinal rows of punctures—in some 
specimens of a reddish golden tint, and in others with more 
of a silver tinge. The thorax is broad and the head large, 
with strong, sharp mandibles and prominent palpi, the 
whole insect measuring from six-eighths of an inch up to 
an inch. 
Both of these beetles are found here in Manchester, Cal¬ 
osoma calidum being rather common in certain sections of 
the city, while the scrutator is more rare, the writer having 
seen but one during the past two years, that being brought 
him by a person whom he, half in jest, had instructed to 
look for this very insect, and who recognized it from the 
description given and secured the prize. 
During the day the Hunters generally remain in hiding 
under some friendly stone or clod of earth, and are seldom 
seen until night, when they sally forth in search of their 
prey, and they can often be found under the electric light, 
where they find food in plenty waiting to be eaten. The 
only protection they have, in addition to their speed, is a 
very evil smelling liquid that they are able to eject when 
frightened or hurt. In the case of the scrutator this liquid 
has something the odor of carrion, and in the calidum it is 
something like very strong turpentine and produces a 
brown stain on the skin that is very difficult to remove. 
The larva of Calosoma is similar to the larva of the rest 
of the Carabidse, only being a little larger. It is active,
