Tiemann^ U. S. Naval Ordnance Test Station, China Lake, California Abstract: The life history of the phengodid beetle Zarhipis integripennis (Le Conte) is covered in most of its stages. Included are observations on other species of Zarhipis and the Brazilian "Railroad Worm," Phrixothrix, as well as notes on the millipeds upon which these insects feed. Introduction Since 1887, very little information has been published on the natural history of phengodid larvae — glowworms with luminous bands on the dorsal surface of each abdominal and thoracic segment. The literature on Zarhipis larvae in particular has been minimal. Most of the available material is in the form of notes published from presentations to various entomological society meetings. Rivers ( 1886a), undoubtedly referring to Zarhipis, was the first to note that the insect feeds on millipeds. He reported that the larvae feed on both Poly-desmus and Julus and suggested that they prefer Julus because of its larger size. Later, he described the adult female and referred to the pupa (Rivers, 1886b). He also mentioned the close relationship in the life history of Phengodes and Zarhipis (Rivers, 1887), but did not go into detail. Charles V. Riley (1887) published some notes on the larva and larviform female of Zarhipis and Phen-godes. The late Herbert S. Barber, who worked out much of the biology of the related forms of Phengodes of the eastern United States, published most of his findings as notes also. ifiox 5757, China Lake, Calif. 93555.
