BY LAWRENCE W. SAYLOR, WasUngion, D. C. I am much indebted to Harry Hoogstraal of the University of IlHnois for the privilege of examining and describing the present material. The insects of this group are very abund-ant in neotropical regions and it appears that but a small percentage of the species have been described, and many of the latter are known only from one sex. Phyllophaga (Phytalus) hoogstraali, new species. Male: Oblong-ovate, wider behind. Color piceo-rufous and strongly pruinose dorsally; superficially glabrous above except for a few short and erect frontal hairs, though in reality the thorax and elytra with extremely minute hairs. Clypeus moderately long, the apex slightly reflexed and the middle slightly and narrowly emarginate, the angles broadly rounded; disc with dense, regularly-placed, non-contiguous punctures of moderate size. Front punctured as clypeus though the punctures are somewhat contiguous and larger bordering the eyes; fronto-clypeal suture strongly biarcuate. Antenna 10-segmented, rufous, segments 3-5 short; club subequal to funicle. Thorax strongly transverse, the sides evenly arcuately dilated and coarsely crenate and ciliate, the angles noticeable but obtuse; base completely margined though weakly so at middle; disc densely and regularly umbilicately punctate, the moderately-sized punctures separated by once to twice their diameters, a small and irregu-lar median discal area impunctate. Scutellum densely punctured. Elytra punctured as thorax but more sparsely so; sutural and one discal striae obvious, the latter strongly widened apically. Pygidium convex, and somewhat narrowly apically, the apical and ciliate margin thickened and sub truncate; disc polished, densely and regularly punctate and with suberect hairs. Abdomen flattened at middle and polished, pruinose laterally; 5th segment large, plane, and sparsely and setigerously punctate 6th segment half length of fifth, densely and not coarsely punctate, 4— Pboc.
