Abstract
The present paper results from a taxonomic study of the genera Nemognatha, Zonitis, and Pseudozonitis of the beetle family Melodidae. Only the species occurring north of Mexico are included. A new genus, Rhyphonemognatha, is proposed for a group of four species occurring principally in Mexico but one of which extends from Mexico as far north as Nebraska and Iowa. A discussion of distribution of phylogeny in three genera is given. Thirty-four forms of Nemognatha are recognized of which twenty-seven appear to be discrete species. These are segregated into eight species groups which are divided into four proposed subgenrea. Nineteen forms of fourteen species in the genus Zonitis are included in four species groups forming two subgenre also newly proposed. The genus Pseudozonitis includes thirteen species divisible into five species groups but no subgenera are indicated since the genus itself may possibly be a subgenus of Zonitis. A brief resume of the bionomics of these insects is included. A full synonymy is attempted for each species with the appropriate literature cited in a bibliography. Keys to all the forms are given. A total of sixty-six forms is recognized most of which are redescribed completely and twenty-two of which are new. Distribution maps are given for most of the forms as well as one hundred and eighty-nine figures of taxonomic characters.
