Two New California Coenonycha (Coleoptera - Scarabaeidae)

Abstract

Members of this genus have always been rare in collections due probably to the fact that their habits and hosts have not been known and the proper collecting methods never applied. It was the author's good fortune to discover that they are nocturnal and occur in great abundance in some localities and if collected properly can be taken in large series. It is the purpose of this paper to present a very profitable method of collecting, two new species and the first host records for members of this genus. Much information obtained from studying large series is with- held in favor of Mr. A. T. McClay who is at present preparing a revision of the genus.
