They also attack the roots of the pine-apple. Their fecun- dity is as surprising as their voraciousness. They carry on their depredations chiefly during the night, and secrete themselves during the day in holes and places where it is next to impossible to reach them, always choosing both dry and warm quarters. The males alone have wings, and are less in size than the females, which latter, particularly when loaded with a heavy bag of eggs, which they carry about with them for days until they find a place suitable for depositing them in, are ill calculated for flying, and indeed do not travel further than to secure suSioient food. This may be an important reason why they are so difficult to subdue, notwithstanding hundreds may be trapped or killed week after week. It is probable that the majority of these are males, for they are exceedingly nimble, and travel a considerable distance from their noc- turnal haunts, as may be seen by entering the places they frequent with a lighted candle, when they scamper off into holes and crevices so quickly that it is difficult to destroy them, although they cover the floor by hundreds.
