46 MR. G. A. K. MARSHALL ON COLEOPTERA [Jan. 19, 



length greater than the width at base, which is equal to the apex, 

 sides strongly rounded, broadest about middle ; ocular lobes 

 moderately developed. Upper surface slightly convex, closely 

 set with small elevated shiny tubei'cles, leaving a very narrow 

 central furrow without a carina; tubercles bare, with short 

 depressed setas, the interstices with sparse brown scaling. Elytra 

 oblongo-ovate, shoulders roundedly prominent, much broader than 

 the base of prothorax ; sides not much rounded, broadest before 

 middle ; apical processes absent in $ . Upper surface slightly 

 convex, with shallow closely-punctured stri83 ; intervals with small 

 i-ather distant tubercles, which are somewhat depressed dorsally 

 and near base, but conical towards sides and apex ; intervals 2, 

 4, and 6 with the tubercles more distant than on the others ; 

 interval 1 slightly raised on the declivity in the § and with the 

 tubercles there closely set ; tubercles with a short apical seta ; 

 elytra bare except for a few small scattered patches of yellowish 

 scales. Legs with fine pale scaling; 2nd and 3rd joints of 

 posterior tarsi subequal in length. 



Cape Colony. 



Type in the British Museum. 



The larger and more dista,nt tubercles on the elytra, as well as 

 the comparative narrowness of the prothorax, give this species a 

 very different appearance from its nearest ally, H. deceptor Mshl. 



30. H. suturalis, sp. nov, (Plate I. fig. 9.) 



Long. 19, lat. 8 mm. 



Head very convex, with shallow punctuation, which is close on 

 vertex but sparse in front, forehead with a shallow depression ; 

 eye surrounded by a deep impressed ling ; anteocular furrows 

 distinct. Rostrum cut off from head by a deep dorsal incision, as 

 long as prothorax only, thick and strongly curved. Upper surface 

 convex, with five strong smooth carina?, aU evenly raised, the 

 furrows coarsely punctured ; lateral sulci deep, the upper pair 

 meeting at base and much longer than the lower ; scrobes lateral, 

 rather sinuate ; inferior basal furrow distinct. Antennce with 

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

 subequal. Prothorax distinctly transverse, apex narrower than 

 base, sides strongly rounded, broadest about middle, dorsal 

 anterior margin ti'uncate, ocular lobes small but distinct. Upper 

 surface almost plane, closely set with low rounded tubercles, 

 leaving a nai'row central furrow without any carina ; tubercles 

 bare and with scai'cely perceptible setse. Ulyti-a obovate, shoulders 

 prominent but rounded, sides evidently rounded, broadest behind 

 middle, apical processes absent. Upper surface slightly convex, 

 strongly sulcate, the sulci with rows of shallow punctures separated 

 by distinct granules ; intervals all evenly costate, not tuberculate, 

 but transversely rugose, except close to apex, where they are more 

 or less distinctly granulate ; the suture distinctly raised on the 

 declivity in the $ and set with a row of short erect black setae ; 

 scaling absent, being replaced \>y short depressed yellow setae,
