This species has a great similarity to A. exiguus but is distinct from it by the more robust form and in having the third antennal joint for one third of its length at base black. It seems to be the western representative of the genus and has been found as far north as the state of ATHEAS AUSTRORIPARIUS Atheas austroriparius n. sp. Body elongate-oval, depressed, black. Later- al margins of the pronotum and elytra hyaline, yellowish-white. Head hardly broader than long, blackish; antenniferous tubercles prominent, dis- tinctly diverging at apex. Antennae slender, as long as from the apex of the head to the tip of the triangular portion of the pronotum. First two joints equally stout and black, the terminal a little less, blackish, third thin, yellowish, with a short black band at base. Pronotum very feebly convex, narrowing towards the front, closely and deeply punctured, lateral margins straight, narrow post- eriorly, thence widening anteriorly; pronotal cari- nas feeble, somewhat indistinct at the middle, the abbreviated outer ones parallel to the median carina; triangular portion of the pronotum rather short, tip obtusely rounded, yellowish. Elytra somewhat less elongate, widest at the middle and gradually rounding towards apex; discoidal area very long, extending nearly to the tip of the abdomen, with four rows of small areoles at widest part, the outer and inner longitudinal nervures black; subcostal area wider than the costal with three rows of small areoles, the nervures light brown; costal area with one row of medium sized areoles and some smaller cells near the margin; sutural area with larger areo
