Pygarctia Abdominalis Grote. ♂ This genus, allied to Ctenucha, is structurally, characterized by the very small labial palpi, which are not porrected but concealed beneath the head; the dark scales which tip the small terminal joints are projected straightly forward but do not exceed the front. The antennae are somewhat long and stout, shortly bipectinate.
