White Systematic Entomology Laboratory, IIBIII, Agr. Res. Ser\^, USDA^ ABSTRACT — A new genus and 16 new species are described from Central and South America as follows: Serranobiuni, n. gen., S. inernie, Ozognathus grossus, Eiiceiatocents argenteus, Priobium mexicanum, P. costaricense, Lasioderma badiuni, L. megalops, L. mexicanum, L. parvuni, Stagetus coii-vexus, S. minutus, S. paraguayensis, S. platyops, Striatheca rufescens, Neosothes abbreviatus, N. mexicaiius. Keys are presented for the American species of Priobium, Stagetus, and Neosothes and for the Central and South American spe-cies of Lasioderma. Work on Central and South American Anobiidae recently sent to me has resulted in the following descriptions for a new genus and 16 new species. Serranobium White, new genus General: Body elongate cylindrical. Surface sculpture of fine, dense granu-lation. Pubescence very fine, short, appressed. Ground color brown. Head: Eyes moderate in size, strongly bulging. Antenna 11 segmented, less than V-z as long as body, serrate from 3rd through 10th segments, last segment elongated. Last segments of maxillary and labial palpi triangular, each a little longer than wide. Dorsal surface: Pronotum granulate throughout, vague elevations and depres-sions most distinct basally, with a complete, sharp lateral margin. Scutellum large, nearly quadrate, a little longer than wide. Elytra finely granulate through-out, lacking distinct striae, at side with weak striae. Ventral surface: Prothorax excavated; prosternal length before coxae over V2 coxal diameter, prosternum slightly depressed medially; fore coxae moderately produced, separated b>-aliout V2 transverse coxal diameter; niesosternum short, flat; middle coxae separated by about Ms transxerse coxal diameter; metasternum longitudinally grooved at center from before middle to apex; hind coxae separated, widest near middle. Abdomen granulate; first suture distinct throughout, pro-duced posteriorly at middle, broadly V-shaped, 1st and 2nd segments nearly ' Mail address: c o U. S. National Museum, Washington, D. C. 20560.
