Two Genera of Symphyla New to the United States, with Descriptions of Three New Species

As the symphylan fauna of the United States becomes better known, it is very probable that species will be found belonging to all of the genera now known. From California alone I have collected specimens belonging to the following genera: Scutigerella, Hanseniella, Symphylella, Geophilella, and Symphylellopsis.1 Hilton (1931) has reported the genus Scolopendrellopsis from California, and has also named two new genera, Pseudoscutigerella and Scolopendrellina. The former I feel certain is a synonym of Geophilella the latter I have not yet recognized.
