PROC. ENT. SOC. WASH., VOL. 48, NO. 2, FEB., 1946 41 Dorsal head hairs are near the anterior margin, stout, branched. Mental plate with a stout projecting central tooth, circa 12 smaller teeth on each side. Comb of eighth segment of about 24 very long simple spines in a row, projecting well below margin of segment. Respiratory siphon 6 times as long as width at base, tapering to tip, with 2 rows of 5 simple hairs dorsally, and a horizontal rpw of short branched hairs near tip. Siphon finely pilose except at extreme tip. Anal segment as wide as long, gills almost twice as long as segment, rounded at tips. Dorsal hairs in 6 (4 and 2) lateral hairs in 4, all long. Ventral hairs in 2. The whole segment is finely pilose. The thorax and abdomen, as well as the terminal segments, are densely covered with fine short hairs. The lateral hairs of abdominal segments 4—7 are long, simple. Other hairs on the abdominal segments are conspicuous, many-branched, and slightly recurved, the whole giving a distinctive appearance to the larva. The hairy appearance of the larva gives the name to the species. Type locality. Hermitage Dam, Jamaica. Found in epiphy-,tic bromeliads, at an elevation of 1,500 feet. Type. Holotype 1 female. Allotype 1 male, deposited in the U. S. National Museum. STUDIES IN THE MELOLONTHINE SCARAB BEETLE GENERA OF THE AMERICAN CONTINENTS. NO: II— A NEW GENUS AND SPECIES FROM GUATEMALA By Lawrence W. Saylor, Research Associate, California Academy Sciences This very distinctive new genus belongs nearest the genus Ceraspis Serv., from which it may readily be separated by the clypeal shape and the non-incised basal margin of the pro-thorax. ZABACANA, new genus Diagnostic characters: Separable from all American melolonthine genera by the combination of the short stubby body, totally black color, basally-conver-gent sides of the strongly reflexed clypeus, nearly obsolete clypeal suture, strongly sculptured elytra, strongly unequal claws (each pair of which vary in size and shape), and the evenly arcuate, completely margined thoracic base. cf : Body short and robust, the elytra broad and hardly longer than the total width. Clypeus long and narrowed basally, the apex markedly reflexed; clypeal suture entirely lacking at sides, only faintly indicated at the very
