78. H. WAHLBERGI Boll, 



H. loahlbergl Boh. Sclionli. Gen. Cure. viii. 2, p. 376 (1845), 



Long. 13-21, lat. 6-10 mm. 



Head sliagi'eened, with moderately dense brown scaling, vertex 

 convex, forehead bi-oadl}' and deej)ly excavate ; anteocular furrows 

 distinct. Jiostrum not ti'ansvei'sely incised at base, as long as 

 head and prothoi-ax, distinctly curved and dilated near apex. 

 Uppei- surface finely punctui'ed and with dejiressed brown setee, 

 with a central f uri-ow, dilated towards apex and which in some 

 examples is deep throughout, in othei's shallower, or even almost 

 obsolete towards liase ; lateral sulci distinct, the upper pair uniting 

 at base ; scrobes deep and dii-ected beneath base of I'ostrum ; 

 inferior basal furrow distinct. Antennce with scape not I'eaching 

 eye ; the two basal joints of funicle subequal. Prothorax trans- 

 verse, scarcely longer than the width at base, Avhicli is rather 

 broader than the apex, sides dilated into a sharp angular projection 

 about middle, dorsal antei-ior margin truncate, oculai' lobes well 

 developed. Upper suiface almost plane, closely set with elevated 

 tubercles, leaving a, deep central furi'ow containing a strong carina 

 and with its mai'gins subcostate ; tubercles bare, each with a 

 depressed fulvous seta, the interstices with thin bi'own scaling. 

 Elytra ovate, shouldei-s sloping, sides rounded, broadest about 

 middle, apical processes shoi-t and shai'p in § , but often much 

 i-educed and blunt, absent in J • Upper sui-faee convex, with 

 i-egular rows of large deep punctures becoming shallower lateral^; 

 intervals 1, 3, 5, and 7 sti'ongly costate and with lows of small 

 closely-set, or even agglomei-ated, tubercles, which are sepai'ated 

 and more conical near apex ; the remaining intervals quite plane 

 and devoid of tubei'cles ; tubei-cles bai'e and with depressed ful- 

 vous setae, the interspaces sparsely variegated with light and 

 dark patches of scaling. Legs with veiy thin pale scaling and a 

 denser i-ing near apex of femora ; posterior tarsi with the joints 

 of the same width, the 2nd and 3rd subequal in length, 1st longer. 



Natal: Durban (CiY.i5ayl-er), Estcourt, Drakensberg. Trans- 

 vaal : Lydenburg {Dr. J. W. B. Gunning). 



Type in the Stockholm Museum. 



A veiy common species in Natal and varying a good deal both 

 in size and appearance. In some examples the tubercles on the 

 elevated intei-vals of the elyti'a seem to be worn down so that 

 the intervals ai-e almost simply costate, and owing to the deep 

 punctures the sculpturing of the elytra has thus a strongly 

 reticulate appearance.
