MARSHALL ON COLEOPTERA [Jan. 19, shallow transverse impression behind apex, closely set with low rounded tubercles, leaving a narrow but deep central furrow containing no carina; tubercles bare, shiny, each with a shoi't depressed seta, the intex-stices with dense brown scaling. Ely tret oblongo-ovate, narrower in cf, shoulders sloping, sides slightly l-ouncled, bx-oadest about middle, apical processes (in $. only) normally short, blunt axxd porrect, but variable and sometimes entirely absent. Upper surface with shallow sulci containing rows of ill-defined punctures separated by small granules ; the intervals all closely and evenly granulate, 3, 5, and 7 being usually slightly more prominent than the others, but in some examples this is scarcely noticeable ; in interval 3 with a small tubei'cular prominence at the top of the declivity, which is variable in size and sometimes absent; apices of granules bare, each with a depressed seta, interspaces with fairly dense small browxx scaling. Legs distinctly thicker in o* than in § , with sparse brown scaling ; posterior tarsi with the 3rd joint a little broader than the others, 2nd and 3 I'd subequal in length, 1st rather longer. CAPE COLONY : Port Elizabeth {Dr. H. Brauns), Uitenhage {Rev. J. A. O'Neil), Willowmore {Dr. Brcmns), Kowie axxd Kei River [S. A. Mus.]. TYPE in the Stockholxxx Museum. I can detect xxo difference whatever between the types of costaius and bituberculatus. H. punctirostris appears to differ only in its more even elytral intervals and in the absexxce of the apical processes in the $ . These characters aie, however, certainly variable, and I have seen several intermediate examples which render it impossible to regard the two forms as specifically distinct. Father O'Neil writes of this species that it is common at Uitenhage and Grahamstown throughout the year, being generally found under stones on rich soil, but sometimes under dead leaves and humus. 23. H. ANGUSTUS, sp. nov. (Plate I. fig. 5.) Loxxg. 11-121 lat. 4-5 mm. Head convex, rugosely punctured, and with spax*se depressed pale setae, forehead not flattened, but plicate and with a deep impression just above each eye ; anteocular furrows almost obsolete. Rostmtm a little shorter than head and prothorax, with a transverse dorsal incision at base, distinctly curved, rather thicker in $ . Upper surface convex, with five narrow smooth carina?, the central one being a little higher than the others, the intervening sulci closely punctured and clothed with brown seta? ; lateral sulci deep, meeting at base, about equal in length ; scrobes entirely lateral, subparallel with the sulci; inferior basal furrow deep. Antenna with fine whitish pubescence ; scape just reaching eye; the two basal joints of funicle subequal. Prothorax as long as broad m tf, slightly transverse in £, apex narrower than base, with a shallow constriction just behind apex, dorsal |
