38 MR. G. A. K. MARSHALL ON COLEOPTERA [Jiin. 19, 



clepi'essed dark setfe. Legs very thick and coarsely punctui-ed ; 

 the anterior pairs of tibiae distinctly cui'ved, and all of them 

 strongly serrate on the inner edges ; posterior tai'si shoit, the 

 three joints subequal in length and breadth. 



Namaqualand : Bitterfontein. 



Type in the Stockholm Museum. 



A rare species. The sculpturing of the elytra much resembles 

 that of Brachycerus congestus Gerst. 



20. tH. cuRTUs Gyl. 



H. curtus Gyl. Schh. Gen. Cure. v. p. 785 (1840). 



Long. 18, lat. 8 mm. 



Head convex, with very deep punctures and scattered white 

 scaling, foi'ehead somewhat retuse and rugose, anteocular furrows 

 present but not very distinct. Rostrwm separated from head by 

 a deep dorsal transverse incision, very short and thick, shorter than 

 prothorax, strongly curved, dilated towai-ds apex. Upper surface 

 convex, very closely and coai'sely punctured, with a broad smooth 

 central caiina which is bifid apically and bears a faint stria ; 

 upper lateral sulci broad and deep, uniting at base, lower ones 

 shallow and much shorter ; scrobes lateral, deep, and oblique ; 

 inferior basal furrow deep. Antennce with pale recumbent setae ; 

 scape barely reaching eye ; the two basal joints of funicle subequal. 

 Prothorax subgiobose, as long as broad, apex much nai'rower than 

 base, sides rounded, broadest about middle, dorsal anterior margin 

 distinctly convex, ocular lobes prominent. Upper sui'face convex, 

 closely set with low rounded tubercles, leaving a very narrow 

 central furrow without any carina ; tubei'cles bare, each with a 

 depressed pale seta, the interstices fairly closely covered with pale 

 round scales. Elytra shortly ovate, base strongly sinuate, shoulders 

 sloping, sides rounded, broadest about middle, apical processes 

 minute and tubei'culiform. Upper surface convex and distinctly 

 sulcata, the sulci containing rows of small granules ; intervals all 

 similar, costate, each with a row of larger but depressed granules, 

 which are shining and bear depressed pale setee ; the interspaces 

 unevenly clothed with large greyish scales. Legs thick, strongly 

 punctured, and with scattered pale scaling and setse ; posterior 

 tarsi short and broad, the joints subequal in length and breadth ; 

 tibife strongly serrate internally. 



Namaqualand : O'okiep (Z. Peringuey). 



The only example which I have seen of this insect is a $ in 

 Mr. Peringuey's collection. Its only near ally is H. corpulentihs 

 Gyl., from which it may be distinguished not only by the very 

 different sculpturing of the elytra, but also by its larger size, more 

 rotund form, and much less strongly carinate rostrum. 



21, tH. IN FLATUS, sp. nov. 



Long, 17, lat, 9 mm. 



Head convex, deeply and riigosely punctured, forehead not 

 flattened, without furrow or carina ; anteocular furrows indistinct.
