1906.J COLEOPTERA OF THE GEXUS SCIOBIUS. 257 



rows of close punctures, the iutervals almost plane, smooth and 

 impunctate ; colour black, evenly covered with fine and not very 

 dense grey scaling. Legs moderately long and stout, piceous, 

 with the tibiae paler and covered with thin grey pubescence the 

 anterior tibife broad and distinctly curved at apex, the interior 

 edge bisinuate. 



Type S ii^ the Stockholm Museum. 



Natal: Estcourt (^4. E. Haviland). Cape Colony: Kentani 

 {Rev. Dr. Kolhe). 



I have seen only four examples, all of which appear to be 

 males. In the unique type the second interval of the elytra 

 is not dilated, but in two other examples this is the case to a 

 slight extent. The curvature of the anterior tibise and the 

 lateral inflection of the elj^i'a also vary somewhat. It is possible 

 that two species are involved, but they cannot be satisfactorily 

 discriminated without further material. 



18. SciOBius BARKERi, sp. nov. (Plate XVIII. fig. 8.) 



Long. 5-6, lat. 2|— 3 mm. 



Head transverse, convex, finely aciculate, with thin pale seti- 

 form scaling forming a dense ring round the eyes, which are 

 not very prominent ; forehead with a shallow central impression. 

 Rostrum short, as long as the width at base, gradually narrowed 

 towards apex, the gense rounded and not dilated ; upper surface 

 plane, aciculate, and with fine pale setiform scaling, with three 

 narrow carinse, the outer pair straight and parallel, the aiDical 

 emargination very deep and acute. Antennce slender, piceous, 

 with fine pale pubescence ; scape subcompressed, strongly curved 

 and gradually dilated to apex ; funicle with the third joint a little 

 longer than the first, subterminal joints elongate. Prothorax 

 twice as broad as long in the 5 , a little less ti-ansverse in the J 

 distinctly arcuate at base, narrower and truncate at apex ; sides 

 slightly rounded in the $ , more so in the S , broadest rather 

 behind middle ; upper surface convex, set with scattered depressed 

 granules and without any lateral impressions ; colour black, with 

 thin grey or yellowish setiform scaling which is dense beneath 

 and usually forms three denser lines above. Elytra ovate in the 

 5 , narrower and more acuminate posteiiorly in the S , jointly 

 sinuate at base, sides gently rounded in the § , less so in the 

 c? , broadest about middle ; upper surface slightly convex, with 

 fine striee containing shallow punctures separated by small 

 granules, the intervals smooth and devoid of granules, in the 5 

 broad and slightly convex; the second interval is also much 

 dilated and depressed near the base, thus causing the third 

 interval to appear strongly sinuate in its basal half; this 

 character is only faintly indicated in the S , which has all the 

 intervals narrower and more convex; colour black, somewhat 

 thinly covered with minute pale scaling which is denser towards 

 the sides and apex, the scales with either a yellov\^ pinkish, oi- 

 green reflection. Legs slender, piceous, with fine pale pubescence,
