 convex, moderately declivous behind, sub-sulcate, the sulci with 

 obsolete punctvires ; all the intervals elevated, convex, and with 

 distinct remote tubercles posteriorly ; entirely feiTuginous, vaiie- 

 gated with grey and fuscoiis scaling. Body obsoletely punctulate 

 beneath, piceous, with spa,rse grey scaling. Legs elongate, stout, 

 fei'i'iiginous, with spai'se grey scaling and pubescence ; femora

" Cape of Good Hope {Drege)." 



Type missing ; in Drege's collection. 



This description is a translation of that given by Boheman, as 

 I have failed to recognise the insect among the species which I 

 have examined. 



■*30. SciOBius ANGUSTUS, sp. nov. (Plate XIX. fig. 2.) 



Long. 6, lat. 2| mm. 



Head moderately transverse, slightly convex, evenly coriaceous 

 and with sparse pale scaling which is denser round the eyes ; fore- 

 head scarcely impressed in middle ; eyes convex but not prominent. 

 Rostrum longer than broad, basal margin obtusely angulate, sides 

 parallel to near apex, genfe rounded and slightly dilated ; upper 

 surface plane, rugulose, tricarinate, the outer carina; straight and 

 parallel throughout. Antennce elongate, but comparatively stout, 

 piceous, with thin grey pubescence ; scape compressed, modeiutely 

 curved and gradually thickened to apex ; f unicle with the first and 

 third joints equal. Prothorax moderately transverse, truncate at 

 base and apex, sides straight from base to well beyond middle, 

 thence rapidly narrowed to apex ; upper surface somewhat convex, 

 coriaceous, sparsely set with small granules and without distinct 

 impressions ; colour black, with fairly dense greenish-grey scaling. 

 Elytra elongato-ovate, truncate at base, shoulders subrectangular, 

 scarcely prominent but with a faint humeral tubercle, sides gently 

 rounded, broadest about middle ; upper surface convex, with rather 

 shallow stri83 containing rows of strong punctures separated by 

 small granules, the intervals rather nari'ow, of equal v/idth, 

 coriaceous and devoid of gra,nules ; colour black, fairly densely 

 covered with fine greenish-grey scaling ; in perfect specimens this 

 is probably uniform throughout, but in the type the discal portion 

 is somewhat abraded. Legs moderate, piceous, Avith thin grey 

 scaling ; anterior tibia; straight externally, the first tai'sal joint 

 elongate, longer than either of the next two. 



Type S in the South African Museum. 



Transvaal : Shilouvane {Rev. II. Junod). 



A rather small, very narrow species belonging to the group 

 represented by marginaius Fahr., from which latter it may be 

 distinguished by the more prominent central carina of the rostrum, 

 the fine and sparse granulation of the thorax, and the narrower 

 and more convex elytra, as well as by the very different coloration.
