32. H. GRANULOSUS Thunb. 



H. granulosus Thunb. Nov. Act. Ups. vii. p. 120 (1815); Gyl. 

 Schh. Gen. Cure. i. p. 484 (1833), v. p. 792 (1840). 



Long. 14-15, lat. 5|-6 mm. 



Head very convex, bare, closely and strongly punctured, fore- 

 head with a very deep longitudinal impression on each side ; 

 anteocular furrows present, but rather indistinct. Rostrum cut 

 off from head by a deep basal incision, very short and thick, not 

 more than two-thirds the length of prothorax, distinctly curved. 

 Upper surface almost plane, very rugosely punctured, and with a 

 strong smooth central furrow ; upper lateral sulci broad and deep, 

 uniting at base, lower sulci very short and subtriangular ; scrobes 

 lateral and oblique ; inferior basal furrow broad and deep. 

 Antennce with scape just reaching eye ; the two basal joints of 

 funicle subequal. Prothorax transverse, apex narrower than 

 base, sides very strongly rounded, broadest about middle, anterior 

 margin slightly convex, ocular lobes well developed. Upper 

 surface almost plane, closely set with low I'ounded tubercles, 

 leaving a narrow indistinct central furrow without any carina ; 

 tubercles unipunctate but usually without setse, interstices with 

 only a very few widely- separated white scales. Elytra oblongo- 

 ovate, rather broader in 5 , shoulders roundedly prominent, sides 

 subparallel to beyond middle, apical processes absent. Upper 

 surface convex, sulcate, sulci containing rows of distinct granules, 

 but in some cases the granules join the intervals on either side, so 

 that the sulci then appear to contain rows of large subreticulate 

 foveee ; intervals all similar, each bearing a single regvdar i-ow of 

 low rounded tubercles, which are apt to become catenulate on 

 disk ; tubercles bare and without setse, interstices with very few 

 small and widely-separated white scales. Legs with a few sparse 

 white scales ; posterior tarsi with joints of the same width ; 2nd 

 and 3rd subequal in leng-th, 1st a little longer. 



Cape Colony : Hex River, Constantia. 



Its remarkably short rostrum will immediately distinguish this 

 species from any other in the genus. In some examples the 

 sculpturing of the head is much more rugose and the two longi- 

 tudinal impresssions are then not noticeable. One such example 

 in the South African Museum is much larger than usual, and the 

 reticulations on the elytra are also very much larger, giving the 

 insect a very different appeai-ance. But without further material 

 it seems advisable to regard this as merely a varietal form.
