and more the rule in the hot and moist forests of the tropics. 
Here the physical environment of the animal is undoubtedly 
the primary cause of its high colors. 
The buds of plants and trees are imitated by many kinds 
of weevils, whose oval, often rough, bodies and sluggish 
natures protect them. Such is the plum weevil (Fig. 210), 
which looks like a dried plum bud. The small cones of the 
pine are simulated by the Chalcophora liberta , a Buprestid 
beetle. Early in June when the brown Elaters are coming 
out of the ground and are found resting on the low maple 
bushes, I have observed some to resemble closely the long 
leaf buds of that tree. 
Certain small weevils resemble the seedls of plants. Wal-

lace quotes Kirby and Spence’s statement that the small 
weevil named Outhophilus sulcatus looks like the seed of an 
umbelliferous plant. Wallace also quotes Bates as saying 
that some tropical spiders “are exactly like flower buds, and 
take their station in the axils of leaves, where they remain 
motionless waiting for their prey.” 
Some beetles, like the little, thick, rounded, oblong Chla- 
mys, have been noticed by Bates, and also by Wallace, to 
resemble the castings of large caterpillars, and the case of 
the larva of this beetle (Fig. 211), which is not uncom-
