Chalepoderus hiaticollis, sp. n. (PL V. figs. 9, 9 a.) 



^ ? . Integument black or piceous, covered with dense 

 uniform earth-brown scaling. 



Head with the forehead broad, quite flat, and rather 

 strongly wrinkled longitudinally, but the sculpture almost 

 entirely concealed by the scaling; the eves longitudinal, 

 rather strongly convex. Rostrum about as long as broad, 

 slightly narrowed from the base to the middle, then dilated 

 to near the apex ; the elevated dorsal area narrowest just 

 behind the scrobes and much dilated behind, with a broad 

 shallow depression in the middle, rather steeply declivous at 

 the base, and with the basal angles broadly rounded ; the 

 interantennal area impressed, shining, strongly punctate, 

 and with isolated scales in the punctures, with a low median 

 carina in front, turning into a short deep stria behind. 

 AnteaJKB with the scape gently curved, gradually clavate, 

 densely squamose, and with stout subrecumbent setse ; the 

 funicle with joint 2 a little longer and not more slender 

 than 1, 3 shorter than 1, 4-7 still shorter, subequal, and 

 longer than broad. Prothorax about twice as broad as long, 

 the basal margin truncate and fitting under the base of the 

 elytra ; the dorsum closely set (except along the apical area) 

 with squamose conical tubercles, which are highest, and 

 form a steep wall, along each side of the broad median 

 sulcus, there being also an oblique non-tuberculate impres- 

 sion on each side in the basal half ; each tubercle with a 

 stout compressed seta at its apex. Elytra broadly ovate, 

 widest somewhat before the middle, jointly but shallowly 

 sinuate at the base, and obtusely acuminate at the apex ; 

 the longitudinal outline rising very steeply for a short 

 distance from the base, then moderately convex, the pos- 

 terior declivity steep and the actual apex somewhat 

 retracted ; the dorsum deeply striate, the strise becoming 

 shallower behind and containing spaced punctures that are 

 completely hidden by the scaling; the intervals broad and 

 convex, each bearing a row of obliquely raised, flattened 

 setae ; the scales smaller than those on the pronotum, not 

 overlapping, round, convex, and finely ribbed. Legs densely 

 squamose and with numerous subrecumbent setae. 



Length 6*5-7*75 mm., breadth 3*5-4 mm. 



Cape Province : East London, 1915 {Lightfoot). 



Described from four specimens.
