1906,] COLEOPTEEA OF THE GEJ^^US SCIOBIUS, 249 



From the former it also differs in its broader scape, rounded gente, 

 the irregular punctuation of the elytra, and the tuberculation of 

 the intervals. The two latter characters also distinguish it from 

 cognatm, as well as the parallel outer carinse of the rostrum, the 

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

 wide separation of the minute white setss on the intervals, and the 

 less compressed and less cm-ved scape. 



■*8. SCIOBIUS IMPRESSICOLLIS Boll. 



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



Long. 6i-71, 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, gense not dilated ; 

 upper surface plane, strigosely punctate, distinctly tricarinate, the 

 outer carinas straight and parallel. Antennce moderate, piceous, 

 with sparse grey scaling ; scape compressed, strigoso-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 Avhich is denser laterally. 

 Elytra broadly ovate, jointly sinuate at base, sides moderately 

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

 distinct strife containing shallow punctures separated by small 

 granules Avhich 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, Avith 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 brevicoUis Fahr. 5 .
