large tubercle at base ; at the apex of interval 3 there is occasionally 

 seen a distinct tubercular projection (var. rhamphastus Gyl.), but 

 this is very variable in development and is more often absent ; 

 the elytra are sparsely covered with small greyish scales, which 

 are larger and whiter on the inflexed margins. Legs thinly 

 clothed with whitish setae ; posterior tarsi with the 3rd joint 

 slightly broader than the others, 2nd and 3rd subequal, 1st a little 

 longer. 



Cape Colony : Cape Town. 



H. rliamfliasUis of Gyllenhal can only be regarded as a variety 

 of this species, the development of the intra-apical callus being 

 very variable, and quite unreliable as a specific character. 



Mr. Peringuey states that although this species is fairly common 

 on the flats about Cape Town, he has never found it on the 

 mountains.

Long. 10-11, lat. 4|-5 mm.- 



Head convex, dispersely punctured and scaled ; forehead not 

 retuse, but with a shallow central impi'ession, an impressed curved 

 line above eye ; anteocular furrows deep. Rostrimn rather longer 

 than prothorax, separated from head by a deep incision, thick, 

 distinctly curved and dilated at apex. Upper surface coarsely 

 punctured, with five strong smooth carinse of about even height ; 

 lateral sulci deep, the upper pair m^ich longer than the lower and 

 meeting at base ; scrobes deep, lateral ; inferior basal furrow 

 very deep. Antennas with scape scarcely reaching eye ; the two 

 basal joints of funicle subequal. Prothorax slightly transverse, 

 apex and base of equal width, sides rounded, broadest at middle, 

 dorsal anterior margin truncate, ocular lobes moderate. Upper 

 surface convex, fairly closely set with small rounded tubercles, 

 leaving a distinct central furrow containing no carina ; tubercles 

 bare, shiny and with short depressed setse, the interstices with 



3 distinct longitudinal lines of white scales. Elytra ovate, 

 shoulders roundedly prominent, sides rounded, broadest about 

 middle, apical processes absent. Upper surface convex, with 

 regular rows of large subreticulate punctures ; the intervals 1 , 3, 

 5, and 7 much more raised than the others, strongi}?- costate and 

 with distinct traces of depressed setigerous granules ; intervals 2, 



4 and 6 quite plane and smooth, and densely clothed with small 

 greyish or yellowish scaling, whei-eas the elevated intervals are 

 quite bare. Legs sparsely covered with whitish setse ; posterior 

 tarsi with the joints of about the same width, 2nd and 3rd sub- 

 equal, 1st rather longer.

Gyllenhal's specimen, which is one of the many missing types 

 from Drege's collection, was evidently abraded, as is not unusual 

 in this species. The insect is a very near ally of caffer Thunb., 

 from which it diflfers in its much smaller size ; its shape, beino-
