Show 76 MR. G. A. K. MARSHALL ON COLEOPTERA [Jail. 19, tubercles disappearing near apex; interval 2 with small rounded distant tubercles, which are conical posteriorly; 3 and 5 with more closely-set, but not smaller, tubercles, also becoming sharply conical towards apex ; 4 and 6 sometimes without tubercles, but usually with several isolated ones; 7 with a complete row of conical tubercles of almost the same size throughout; tubercles bare, with depressed dark seta?, the interspaces with fulvous scaling, largely variegated with white. Legs with scattered large round white scales; postex-ior tax-si with the joints of the same width, 2nd and 3rd subequal in length, 1st rather longer. N A M A Q U A L A N D : O'okiep {L. Peringuey). C A P E COLONY : Willow - more {Dr. H. Brauns), Worcestex-, Fraserburg, and Swellendam. TYPE in the Stockholm Museum. M y only example from Willowmore has tlxe scape axxd also the joints of the funicle x-ather longer than in the Namaqualand specimens, and the carination of the rostrum is slightly more pronounced. The other Cape Colony examples are characterised by their less elongate form, duller colouring, and the larger tubercles on tlxe elytoa. Mi-. Peringuey states that this species is common in Little Namaqualand, both on the coast sand-dunes and further inland at an elevation of 3000 ft. 62. H. VAFER Fahr. H. vafer Fahr. Schh. Gen. Cure. v. p. 755 (1840). Long. 19-26, lat. &§-10| m m. Head convex, with distinct scattered punctures and sparse scaling, forehead not flattened and with a faint central stria ; anteocular furrows deep, rather convex-gent dorsally. Rostrum not incised at base, as long as head and prothox-ax, slightly curved. Upper surface rather convex at base, shallowly excavate near apex, strongly and closely punctured except for a low smooth central carina ; lateral sulci strong, the upper pair uniting at base ; scrobes directed to beneath base of rostrum ; inferior basal furrow almost obsolete. Antennae with scape almost reaching eye; tlxe two basal joints of funicle subequal. Prothoi-ax a little broader than long, apex narrower than base, sides rounded, broadest about middle, apical margin convex, ocular lobes well developed. Upper surface convex, fairly closely set with low rounded separated tubercles, leaving a narrow central furrow containing a fine carina; tubercles bare, without setae, interstices with pale brown scaling. Elytra ovate, shoulders sloping, sides rounded, broadest about middle, apical processes short and thick but sharply pointed and directed upwards. Upper surface convex, with regular rows of distinct granules; interval 1 granulate; 2, 3, 5, and 7 with complete rows of small tubercles, low and rounded on disk, but conical towards sides and apex, tlxe tubercles on interval 2 set much further apart than the others; intervals 4 and 6 without tubercles or only a few low isolated ones ; tubercles bare, usually without setae, interstices with scattered brownish scaling.
