The Food Relations of the Carabidce and Coccinellidas.

upon are Harpalus, taken by twenty-eight of the birds, Anisodac- 
tylus by eighteen, Agonoderus by fourteen, Cratacanthus by thir- 
teen, Pterostichus by twelve, and Evarthrus by eleven; numbers 
which represent fairly well the relative abundance of individuals, 
taking the entire season through. We note, however, a remarka- 
ble deficiency of the highly colored genera, — such as Galerita, 
Brachynus, Lebia, Platynus, Chkenius, etc., which are either 
absent, or found but rarely in these birds’ food. Evidently these 
more showy beetles are protected by some more effective 
means than obscurity of color. In the following list, the figure 
preceding the name of each species of bird denotes the number 
of specimens in which the insect mentioned was found:
