248 ME. G, A. K. MARSHALL OX THE [Mar. 20, 



broad but faint chevi-on-shaped mai'king behind middle, the 

 intervals with rows of minute depressed white seta? which ai-e 

 more noticeable posteriorly. Legs short and stout, piceous and 

 unifoi'mly covered with greyish scaling ; the anterior tibife are 

 slightly more ciu'ved at the apex in the c? , but otherwise the legs 

 are similar in the two sexes.

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



Closely allied to dealbatus Fahr., Avhich it evidently replaces in 

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

 distinguished by the broader scape, the rounded gen?e, the 

 narrower elytral intervals, the more deeply pimctiu-ed strife, and 

 the less oblique shoulders. 



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



Long. 5f-6, lat. 24-3i mm. 



Head strongly transverse, coriaceous and covered Avith dense 

 opalescent white scaling ; forehead with three shallow impressions 

 and a slightly raised fold above the eyes, which are pi-ominent. 

 Rostrum subquadrate, a little longer than broad, genne moderately 

 and i-oundly dilated in both sexes ; upper surface almost plane, 

 tricai'inate, 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 Avith 

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

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

 the third. Prothorax nearly twice as broad as long, base slightly 

 bisinuate, apex a little nari'ower and truncate, sides moderately 

 rounded, broadest about middle ; upper surface convex, dispersely 

 gi'anulate, and with a rounded impression 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 oljlique, sides moderately 

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

 sexes ; upper surface convex, with faint stria? containing very 

 shallow punctiu'es. When the scaling is removed these punctux'es 

 are seen to be uneven and irregular and entirely disappeai- 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 Avhite setse, but without the scaling the intervals appear 

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

 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 (6'. N. Barker), Howick {Dr. F. D. Brown). 



Type, 5 in the Bi-itish Museum, S in the Oxford Museum. 



Allied to dealbatus F§,hr. and cognatus Mshl., from both of 

 Avhich it differs in its smaller size and very different coloration.
