Show 80 MR. <;. A. K. MARSHALL ON COLEOPTERA [Jan. 19, dilated to apex. Upper surface elevated (more markedly so in some specimens), almost plane, finely but distinctly punctured, and with a narrow deep central furrow, vanishing anteriorly ; lateral sulci distinct, both pairs uniting at base, the lower especially forming a vexy deep oblique impression just befoi-e base; scrobes very deep, directed beneath base of rostrum; inferior basal furrow absent. Antennas thinly squamose, scape just reaching eye ; the two basal joints of funicle subequal. Prothorax transverse, apex narrower than base, sides slightly rounded, broadest about middle, dorsal anterior margin truncate, ocular lobes vexy feeble. Upper surface slightly convex, closely set with elevated tubercles, leaving a central fur-row sometimes containing a faint carina; tubercles bare, with depressed pale seta?, tlxe intex-stices with dense brown scaling. Elytra ovate, slightly narrower in o* i shoulders prominent, almost rectangular, sides slightly rounded, broadest about middle, apical processes shox-t arrd sharply conical in $ , much x-educed in o* • Upper surface convex, with rows of small shallow ocellated punctures ; intervals 1, 3, 5, and 7 strongly costate and with catenulated rows of depressed granules, which are more elevated and separated near apex ; intervals 2, 4, and b' quite smooth and devoid of granules ; granules bare and with depressed pale seta?, the interspaces with uniform dense brown scaling. Legs with very sparse pale scaling; posterior tarsi broad, the 3rd joint rather broader than the others, 2nd and 3rd subequal in length, 1st longer. CAPE COLONY : Algoa Bay {Dr. H. Brauns). A very distinct and yet a variable species. In the British Museum is an example beax-ing the name cylindrifer (Jekel, MS.) which represents a vexy extreme form: the forehead is very stx-ongly retuse; the tubercles of the prothorax are much fewer, cylindrical and spinifoi-m, those on elytra are all separate and distinctly conical ; and, finally, the elytx-a ax-e markedly shorter than in the typical form and subquadrate. With the exception of the last, all these characters merge gradually into those of the typical form; and the shor-tness of the elytra is probably only an individual variation. Jekel's specimen is labelled " Natal," but the locality is highly doubtful. 67. H. CAUDATUS Fahr. //. caudatus Fahr. Of v. K. Vet. Ak. Fbrh. p. 209 (1871). Long. 15, lat. 6i mm. Head convex, obscurely punctured and with fine brown scaling forehead without fovea or carina ; anteoculax- furrows distinct, but invisible from above. Rostrum not incised at base, as long as head and prothorax, strongly curved and dilated apically. Upper surface with a broad complete central furrow and with thin setiform scaling throughout; lateral sulci not meeting at base, tlxe upper pair rather indistinct, the lower longer and deeper; scrobes directed to beneath base of rostrum ; inferior basal furrow absent. Antennas with fine fulvous seta?; scape not nearly reaching |
