TWO GENERA OF TETTIGELLIDAE PROPOSEDBY MELICHARZ. P. METCALFNorth Carolina State College of Agriculture and Engineering, RaleighMelichar (1924a) commenced a revision of the Cicadellidae, now known asthe Tettigellidae, and this was continued during 1925a, 1926a, and 1932a, but,unfortunately, was never completed. In his key to the tribe Cicadellini (1926a:340) he proposed 65 new genera. Of this number only 13 were described and hadspecies assigned to them. China (1927d and 1938d) straightened out these newgenera and published a list of the new genera with the genotype designations basedon Melichar's unpublished manuscript. Evans (1947a) cataloged these generaand cited types of the 80 genera established by Melichar. Seventeen genera werebased on new species which have never been described. Since these new specieshave not been published and these new genera have not been fully described, andsince a portion of Melichar's collection has fallen into my hands, I deem it advisableto describe the new genera proposed and also the new species in an attempt toestablish these new genera and species as far as possible.The two genera that I want to establish in the present paper are LuzoniellaMelichar (1926a: 341) and Polisanella Melichar (1926a: 343).Luzoniana nom. nov.pro Luzoniella Melichar (1926) Ann.

But since I have had trouble in determining other generaon the basis of this couplet, I assume that either the character is not a good one or my under-standing of what Melichar intended to imply by these words is faulty.Head broad, including the compound eyes, slightly broader than the pronotum; anteriormargin of the crown broadly rounded, posterior margin deeply incised, the median third nearlystraight; the whole posterior border distinctly and sharply carinate; muscular impressions of thepostclypeus plainly visible on the crown; central area of the crown distinctly and broadly im-pressed, including the area of the ocelli; face large; with the postclypeus rather strongly inflated;no median impression, lateral muscular impressions short, not very deep; genae narrow; jugasmall, broadly rounded laterad; anteclypeus small.

Mesonotum flat, transversely deeply incised just before the apical third,with two impressed points just anterior to the impressed line. Tegmina elongate, narrow,nearly parallel sided, with four apical and three ante-apical cells; cubital cell large, nearly twiceas long as the apical cells and about twice as broad; four distinct cross veins between media andcubitus; claval veins not very distinct. Legs rather long and slender, the anterior tibiae with arow of setae on the posterior margin and a row of elongate slender spines on the anterior margin;posterior tibiae with the usual double row of stout spines on the lateral margins. Abdomenrather broad and short, lateral margins of the segments exposed beyond the tegmina. Femalegenitalia elongate, compressed. Pygofers more than four times as long as broad; last ventralsegment twice as long as the penultimate, twice as broad as long, posterior margin broadly incised,broadly produced medianly.General color of the head and pronotum ochraceous with a greenish tinge marked withfuscous as follows: lateral arcs on the crown and the face; a small elongate triangular spot at theanterior inner corners of the compound eyes; a small elongate oval spot at the anterior margin ofthe head on the median line; a small round spot on the median line of the face at about the levelof the upper margin of the compound eyes; pronotum with three pairs of somewhat pustularspots behind the compound eyes; and mesonotum with three pairs of indistinct fuscous obconicalmarks on the anterior margin. Tegmina somewhat tawny. Abdomen dorsally with eachsegment with a broad basal fuscous fascia, separated from a narrower apical fuscous fascia by anarrow ochraceous fascia; extreme lateral margin, and the last dorsal segment ochraceous buff;ventrally the head, thorax, and legs chiefly ochraceous with some fuscous shading; abdomenventrally chiefly fuscous with the genital segments greenish ochraceous.Length to apex of tegmina 8.6 mm.Holotype female, Northern Luzon.Polisanella MelicharPolisanella Melichar (1926a: 343) [Key, sine sp.]Logotype Polisanella bakeri Evans (1947a: 164)This genus may be characterized as having a rather narrow head with the crown somewhatprotuberant, distinctly separated from the face by a sharp carina; pronotum broad, the anteriormargin distinctly and continuously rounded from the shoulders; tegmina elongate with thevenation fairly regular, fine and indistinct.EXPLANATION OF FIGURES IN PLATE1.
