declivity ; interval 3, however, has a short additional row about 

 the summit of the declivity ; tubercles bare, each with a minute 

 depressed seta ; interstices with large round white scaling, which 

 is very sparse on disk but dense towards the sides. Legs with 

 sparse white scaling and long black setfe ; the joints of posterior 

 tarsi broad, spongy beneath, and subequal in leng-th and breadth. 



Cape CoLoiirT. 



Allied to H. verrucellus Gyl., but this is a larger and more 

 robust insect ; the central furrow on the rostrum is less deep, the 

 prothorax is shorter and its sides much more strongly rounded, 

 and the elytra lack the elevated tubercles on the declivity which 

 are present in veri-ucellus.

H. GongesUis Mshl. 1. c. p. 440 (1902). 



Long. 13-17, lat. 6-8 mm. 



Head convex, with rugose punctures, some of which contain a 

 large white scale ; forehead not flattened, coarsely striate ; ante- 

 ocular furrows deep and complete. Rostrum as long as the pro- 

 thorax only, separated from head by a deep dorsal incision, 

 distinctly curved, subparallel to beyond middle and then very 

 slightly dilated. Upper surface convex, with a deep narrow 

 central furrow throughout having a broad and coarsely-punctured 

 costa on either side ; lateral sulci not meeting at base, both paiis 

 deep and distinct, of equal length and filled with white squamae ; 

 scrobes deep and lateral, almost parallel to the sulci ; inferior 

 basal biu-row broad and deep. Antennce with scape just reaching 

 eyes ; the two basal joints of funicle subequal, Prothorax nearly 

 as long as broad, the length equal to the width at base, apex much 

 narrower, sides very little rounded, slightly diverging from base 

 to near apex, then rapidly narrowing, IJpper surface convex, 

 closely set with large rounded shiny tubercles, leaving a very 

 narrow, and sometimes obsolete, central furrow containing no 

 carina ; granules bare, with depressed dark sette, the interstices 

 with a few scattered white scales ; dorsal anterior margin convex, 

 ocular lobes strongly developed. Elytra broadly oblongo-ovate in 

 5 , much narrower in (5 , shoulders prominent and subrect- 

 angular, sides rounded, broadest about middle, apical processes 

 very short but sharp in both sexes. Upper surface convex, with 

 no distinct striation, the whole surface being equally covered 

 with even and regular rows of rounded granules, except for a 

 tubercular prominence on the declivity of the third interval (as 

 in alhicinctus Gyl.), and a much lower elongate one on the declivity 

 of interval 5 ; these prominences are sometimes a good deal reduced 

 in the S ', granules bare and with very short depressed dark seta"-, 

 the interstices with a few isolated white scales which are moie 

 numerous near the margins, and a small but distinct white spot 

 at the apex of the suture. Legs with scattered white scales and 

 black setae ; the inner edges of tibiae strongly dentate ; posterior 

 tarsi with the three basal joints subequal in length and breadth.
