carina ; tubei'cles bai'e, sometimes with minute setse, the interstices 

 with dense fulvous scaling, the central furrow and sides paler. 

 Elytra ovate, nari'ower in S , shoulders sloping, sides rounded, 

 broadest about middle, apical processes short and sharply conical 

 in both sexes. Upper siirf ace convex, with regular rows of distinct 

 granules which often vanish towards apex ; the intervals with 

 I'ows of large, but variable, rounded tubercles which become 

 conical posteriorly ; those on intervals 2, 4, and 6 usually more 

 widely separated than the others ; tubercles never cristate on the 

 declivity, bare, shiny, and with very shoi't depressed setse, the 

 interspaces with dense fulvous scaling becoming paler laterally, 

 and sometimes with a large pale patch on the declivity. Legs 

 with scattered round white scales and depressed black setse ; 

 posterior tarsi broad, the joints of the same width, 2nd and 3rd 

 of equal length, 1st longer.

Type in the Stockholm Museum. 



A comm.on arboreal species throughout the South-eastern 

 districts of South Afiica. The typical form, which in most 

 collections stands under Boheman's MS. name tuherculatiLS, has 

 the elytral tubercles moi'e evenly distributed and approximately 

 of more equal size throughout, the colouring is also of a more 

 greyish brown and without paler patches ; this form is most 

 prevalent on the coast and in the more low-lying inland localities. 

 The high veldt form has the scaling more mai-kedly fulvous in 

 colour and usually with two large pale patches on the declivity, 

 the tubercles on intervals 3 and 5 ai'e much smaller and more 

 closely set, those on 2 and 4 being larger and often widely sepa- 

 rated ; this form is also of i-ather more robust habit, but the 

 differences mentioned are very variable and cannot be regarded as 

 of specific value. 



35. tH. variegatus, sp. nov. 



Long. 20, lat. 9 mm. 



Head convex, obscurely punctured and with depressed fulvous 

 set«, base of rostrum produced acutely on to the forehead; ante- 

 ocular furrows very deep, approaching very closely above in an 

 oblique direction. Rostrimi not incised transvei"sely at base, 

 longer than head and pi-othorax, strongly curved and dilated at 

 apex only. Upper surface shallowly punctured and sparsely 

 setose, plane or slightly convex, with a shallow impression near 

 apex, a very deep elongate fovea at base, and a faint smooth 

 central carina ; upper lateral sulci obsolete, the lower pair deep 

 and curved upwards at base ; scrobes deep, directed beneath base 

 of rostrum ; inferior basal furrow shallow. Aniennce with scape 

 barely reaching eye ; the two basal joints of funicle subequal. 

 Prothorax longer than its width at base, which is bi'oader than
