1906.] COLBOPTERA OF THE GENIUS SCIOBIUS. 249 



From the former it also difiers in its broader scape, rounded gense, 

 the irregular punctuation of the elytra, and the tuberculation of 

 the intervals. The two latter characters also distinguish it fi-om 

 cognatus, as well as the parallel outer carinte of the rostrum, the 

 more oblique shoulders, the less convex intervals of the elytra, the 

 wide sepai'ation of the minute white setse on the intervals, and the 

 less compressed and less curved scape. 



*8. SCIOBIUS IMPRESSICOLLIS Boh. 



S. impressicollis Boh. Schonh. Gen. Cure. vii. 1, p, 199 (1843). 



Long. 6-i-7f , lat. 34-4i mm. 



Head transverse, almost plane, finely plicate ; forehead not im- 

 pressed ; eyes not prominent. Rostrum about as long as broad, 

 subtruncate at base, rather narrowed anteriorly, genes not dilated ; 

 upper surface plane, strigosely punctate, distinctly tiicarinate, the 

 outer "carinps straight and parallel. Aniennce moderate, piceous, 

 with sparse grey sailing ; scape compressed, stidgoso-punctate, 

 strongly bisinuate and gradually thickened to apex ; funicle with 

 the third joint much longer than first. Frothorax very transverse, 

 base slightly arcuate, apex much narrower and truncate ; sides 

 parallel for a short distance from base, then rapidly narrowed to 

 apex, thus forming a very distinct obtuse angulation ; upper sur- 

 face slightly convex, closely set with very depressed subconfluent 

 granules and with a deep impressed line on each side of the base ; 

 colour black, with sparse grey scaling which is denser laterally. 

 Elytra broadly ovate, jointly sinuate at base, sides moderately 

 I'ounded, broadest about middle ; upper surface convex, with 

 distinct striae containing shallow punctures separated by small 

 granuJes which become obsolete behind middle ; the intervals 

 slightly convex, of equal width, transversely rugose, smoother on 

 the declivity, but with traces of small granules; colour black, 

 with thin grey scaling, which is denser laterally. Legs moderate, 

 piceous, with fine grey scaling ; anterior tibiae very slight, curved 

 externally. 



Type $ in the Stockholm Museum. 



" Cape of Good Hope {Brege)." 



This description has been made from the type, which is the 

 only specimen I have seen. The strong angulation of the sides of 

 the prothorax is a very distinctive character ; apart from this the 

 species much resembles hrevicollis Fahr. $ .

Head transverse, aciculate, with fine grey or yellowish scaling
