We had a glimpse now and then into the black depths of the forest, where all was silent except the shrill stridulation of wood-crickets. Now and then a sudden plunge in the water ahead would startle us, caused by heavy fruit or some nocturnal animal dropping from the trees. The two Indians here rested on their paddles and allowed the canoe to drift with the tide.
In the case of the Heliopathes and Oryctes there can hardly be a doubt that the males stridulate in order to call or to excite the females; but with most beetles the stridulation apparently serves both sexes as a mutual call. Beetles stridulate under various emotions, in the same manner as birds use their voices for many purposes besides singing to their mates.

The air was even richer in aroma than it had been in the morning, but its breath seemed to be part of the uncanny stridulation of the katydids. The windows of the dancing-pavilion beyond the level part of the lawn gleamed like so many sheets of yellow fire. Presently its door flew open, sending a slanting shaft of light over the grass

His limbs shrivel, his heart and digestive organs diminish, his insect face is hidden under its bulging contours. His voice becomes a mere stridulation for the stating of formula; he seems deaf to all but properly enunciated problems. The faculty of laughter, save for the sudden discovery of some paradox, is lost to him; his deepest emotion is the evolution of a novel computation.
