248 MR. G. A. K. MARSHALL ON THE [Mar. 20, 



broad but faint chevron-shaped marking behind middle, the 

 intervals with rows of minute depressed white setee which are 

 more noticeable posteriorly. Legs short and stout, piceous and 

 uniformly covered with greyish scaling ; the anterior tibiaa are 

 slightly more curved at the apex in the c? , but otherwise the legs 

 are similar in the two sexes.

 K. M.). 



Type, 5 in the British Museum, S in the Oxford Museum. 



Closely allied to decdbatus Fahr., which it evidently replaces in 

 the upland districts of Natal. From that species it may be 

 distinguished by the broader scape, the rounded gense, the 

 narrower elytral intervals, the more deeply punctured strise, and 

 the less oblique shoulders. 



7, SciOBius OPALINUS, sp. nov, (Plate XVIII. fig. 4.) 



Long. 5|— 6, lat. 2|— 34^ mm. 



Head strongly transverse, coriaceous and covered with dense 

 opalescent white scaling ; forehead with three shallow impressions 

 and a slightly raised fold above the eyes, which are prominent. 

 Rostrimi subquadrate, a little longer than broad, gense moderately 

 and roundly dilated in both sexes ; upper surface almost plane, 

 tricarinate, with punctuation and scaling as on the head, the 

 central carina only bare and smooth, the outer carinte straight 

 and parallel. Antennce comparatively short and thick, black with 

 fine pale scaling ; the scape curved and compressed, strigoso-punctate, 

 first joint of the funicle broader than the rest, a little longer than 

 the third. Protliorax nearly twice as broad as long, base slightlj'- 

 bisinuate, apes a little narrower and truncate, sides moderately 

 rounded, broadest about middle ; upper surface convex, dispersely 

 granulate, and with a rounded impiession on each side near the 

 base, a few of the granules with their apices bare, the interstices 

 filled with dense opalescent white scaling. Elytra ovate, slightly 

 sinuate at the base, shoulders very oblique, sides moderately 

 rounded, broadest about middle, the shape similar in the two 

 sexes ; upper surface convex, with faint strife containing very 

 shallow punctures. "When the scaling is removed these punctures 

 are seen to be uneven and irregular and entirely disappear behind 

 middle ; in unabraded examples the punctures appear to be small 

 and regular and the intervals broad and smooth, with a few very 

 scattered low rounded tubercles and with widely separated 

 minute white setse, but without the scaling the intervals appear 

 narrower and less regular and a few more tubercles are observable, 

 but these are variable in number and disposition. Legs black or 

 piceous, with uniform pale scaling, moderately short and stout and 

 similar in the two sexes. 



Natal : Malvern {0. N. Barker), Howick {Dr. F. D. Brown). 



Type, 5 in the British Museum, S in the Oxford Museum. 



Allied to dealhatus Fahr. and cognatus Mshl., from both of 

 which it diffei-s in its smaller size and very diiferent coloration.
