North AmericanHerpetogrammaLederer, 1863 (Lepidoptera: Crambidae: Spilomelinae): Type Specimens and Identity of Species in the United States and Canada

Type specimens or the type series of 27 North American Herpetogramma species names were located, mostly in European museums, verified, and dissected. Acharana descripta (Warren) is designated as a new synonym of Herpetogramma phaeopteralis (Guenée). Fifteen lectotypes and 14 paralectotypes are designated where it was deemed necessary to fix and stabilize the current concept of the name. A checklist and a key to nine North American species are provided with photographs of the adults.
