NOTES ON AN ENTOMOLOGICAL ENIGMA

Abstract

It is now more than twenty years since H. S. Barber recorded and described a most peculiar insect larva that had been taken from beneath the dead leaves of tree Yucca at Hesperia, on the Mojave Desert in San Bernardino County, California. It may be recalled that specimens of this larva were taken to Washington, where one of them remained alive without taking food for a period of twenty six months. The species was once more recorded by Couden who reported finding a single specimen in old alcoholic material that had been received from D. W. Coquillett at San Bernardino in 1892.
