STUDIES OF THE MEXICAN DELTOCEPHALINAE : A NEW GENUS, CONVERSANA, AND THREE NEW SPECIES ( HOMOPTERA : Cicadelldoae ) * Dvi'iGHT M. DeLong, Department of Zoology and Entomology, Ohio State University, Columbus, Ohio 43210 Several specimens belonging to three related species were collected in Mexico between 1930 and 1945 during a series of field trips. These are apparently all undescribed and belong to a new genus. Conversana, n. g. Type-species: Conversana reversa new species. Rather small leafhoppers allied to Atanus and Danbara. Head a little broader than pronotum. Crown flat, produced and rounded, distinctly longer at middle than near the eyes, angled with front; anterior margin thick. Forewing with ap-pendix, inner anteapical cell open basally, outer anteapical cell triangular and about half the length of the median anteapical cell. Male plates elongate, triangu-lar; pygofer bearing a short apical spine; aedeagus with an apical process curved cephalad and an anterior, dorsally directed process curved caudally. Color yel-low to pale brown with few markings. Forewings usually without color markings, veins inconspicuous. Conversana conversa, n. sp. (Figs. 1, 2, 3, 4) Resembling superficially a dull colored specimen of Atanus, with few mark-ings and with different head, wings, and genitalia as noted above. Length of male 4 mm, female 4.5 mm. * This work was supported in part by the National Science Foundation ( Grant NSF GB-2932).
