1906.] COLEOPTERA OF THE GENUS SCIOBIUS. 247 



iXLoderately rounded, broadest about middle ; upper surface convex^ 

 dispersely granulate and with a rounded lateral impression on 

 each side of the base, the apices of the granules bare, the 

 interstices filled with dense white or yellowish scaling. Elytra 

 ovate, scarcely differing in shape in the tM^o sexes, shoulders very 

 oblique, sides evenly rounded, broadest about middle ; upper 

 surface convex, with shallow stride containing rows of large 

 shallow separated punctures ; the intervals slightly convex, smooth 

 and finely aciculate, the third rather broader than the others ; 

 colour black or dark brown, with white or yellowish scaling, which 

 is denser apically and throughout the third interval, but the 

 scales vary considerably in density in different individuals ; on 

 the apical half the intervals have rows of very short depressed 

 white setae. Legs piceous, evenly covered with moderately dense 

 white scaling and setee ; in shape and thickness they scarcely differ 

 in the two sexes. 



Type S in the Stockholm Museum. 



N"ataL: Durban {C. N. Barher, A. D. Millar, & H. W. Bell- 

 Marley). 



Yai-ies a good deal in coloration, some examples having the 

 elytra with alternate stripes of lighter and darker scaling. In the 

 type the scaling is uniform in colour, dense and even throughout 

 the sides and declivity, but somewhat abraded on the disk except 

 for the iisual denser stripe on the third interval. 



6. SciOBius COGNATUS, sp. nov. (Plate XYIII. fig. 6.) 



Long. 55— 6|-, lat. 3-3|- mm. 



Head strongly transverse, coriaceous ; the forehead finely plicate, 

 covered with dense grey scaling, and with a slightly raised fold 

 above the eyes, which are prominent. Bostrum subqviadrate, the 

 length equal to the width at base ; genje moderately and roundly 

 dilated, similar in the two sexes ; upper surface broadly excavate, 

 evidently tricaiinate, the outer carinee distinctly sinuate, the 

 whole surface except the central carina densely covered with grey 

 scaling. Antennce rather short and thick, covered with grey 

 scaling, scape broad curved and compressed, strigoso-punctate :, 

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

 third. Prothorax nearly twice as broad as long, base slightly bi- 

 sinuate, apex a little narrower and truncate, sides moderately 

 rounded, broadest about middle ; upper surface convex, dispersely 

 granulate and with a rounded lateral impression on each side of 

 the base, the apices of the granules mostly bare, the interstices 

 filled with dense greyish scaling. Elytra broadly ovate, jointly 

 sinuate at base, shoulders obliquely rounded, sides moderately 

 ampliated, broadest about middle, similar in the two sexes ; upper 

 surface convex, with shallow strife containing rows of large deep 

 punctures (partially concealed by the scaling) ; the intervals rather 

 narrow, smooth and finely aciciilate, the third not broader than 

 the others ; colour black or dark piceous, covered with dense dull 

 grey scaling, variegated with paler scales which usually form a
