-80 MR. G. A. K. MARSHALL ON COLEOPTERA [Jail. 19, 



dilated to apex. Upper surface elevated (more markedly so iu 

 some specimens), almost plane, finely but distinctly punctin-ed, 

 and with a narrow deep central furrow, vanishing anteriorly ; 

 lateral sulci distinct, both pairs uniting at base, the lower espe- 

 cially forming a very deep oblique impi-ession just before base ; 

 scrobes vei'y deep, directed beneath base of i-osti'um ; inferior 

 basal furrow absent. Antennce thinly squamose, scape just 

 reaching eye ; the two basal joints of funicle subequal. Pro- 

 thorax transverse, apex narrower than base, sides slightly rounded, 

 broadest about middle, doi-sal anterior mai'gin truncate, ocular 

 lobes very feeble. Upper surface slightly convex, closely set with 

 elevated tubercles, leaving a central furrow sometimes containing 

 a faint carina ; tubercles bare, with depressed pale setje, the inter- 

 stices with dense brown scaling. Elytra ovate, slightly narrower 

 in S 1 shoulders prominent, almost rectangular, sides slightly 

 rounded, broadest about middle, apical processes short and sharply 

 conical in 5 , much reduced in S • 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 6 quite smooth and devoid of granules ; gi-anules bare and 

 with depressed pale sette, the interspaces with uniform dense 

 brown scaling. Legs with very sparse pale scaling ; posterior 

 tarsi broad, the 3rd joint i-atlier 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 bearing the name cylindrifer (Jekel, MS.) 

 which represents a veiy extreme form : the forehead is very 

 strongly retuse ; the tubercles of the prothorax are much fewei-, 

 cylindrical and spiniforin, those on elytra are all separate and 

 distinctly conical ; and, finally, the el}i)ra are 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 foi-m ; and the shortness of the elytra is probably only an 

 individual vai-iation. Jekel's specimen is labelled " Natal," but 

 the locality is highly doubtful.

Long. 15, lat. 6^ mm. 



Head convex, obscurely punctured and with fine brown scaling, 

 forehead without fovea or carina ; anteocular fuiTOws 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 fuirow and with thin 

 setiform scaling throughout ; lateral sulci not meeting at base, 

 the upper pair rather indistinct, the lower longer and deeper ; 

 scrobes directed to beneath base of rostrum ; inferior basal furrow 

 absent. Antennce with fine fulvous set?e ; scape not nearly reaching
