1906.] COLEOPTERA OF THE GENUS SCIOBIUS. 253 



narrow caiiiiJB, the outer ones often indistinct. Antennce long 

 and slender, piceous, or piceous with the funicle ferruginous, with 

 very fine thin pale pubescence; scape subcompressed, strongly 

 bisinuate, rather abruptly clavate, funicle with the third joint 

 much longer than the first, subterminal ones elongate. Prothorax 

 very short, strongly transverse, basal margin arcuate or sub- 

 bisinuate, sides i-ounded, broadest near base, broadly constricted 

 near apex, which is truncate and much narrower than the base ; 

 upper surface convex, closely set with small depressed gi-anules 

 and with a short longitudinal impression on each side of the 

 base ; colour black, granules bare, the interstices with fine grey 

 pubescence, which is denser laterally. Elytra suborbicular, jointly 

 sinuate at base, sides strongly rounded, broadest at middle ; upper 

 surface convex in $ , subdepi-essed in <S , punctato-striate, with 

 the strife deeper laterally and containing rows of shallow punctures 

 separated by small granules, the doi'sal intervals broad and almost 

 plane, smooth and coi-iaeeous, the lateral ones subconvex, the 

 seventh and eighth bearing rows of granules, which are sharp and 

 prominent in the $ , but inconspicuous in the S \ colour black, 

 Avith very sparse, fine, setiform, grey scaling. Legs slender, 

 thicker in the S , piceous, with thin pale pubescence, the anterior 

 pairs of tibijB broader and moi'e strongly curved in the S • 



Types S $ in the Stockholm Miiseum. 



PoNDOLAXD : Port St. John (G. Shortridge). 



Including the types, I have seen only one S and three $ $ 

 of this species ; yet I have little doubt that the deplcmatus of 

 Boheman must be regarded as the S of his granipennis, for the 

 differences in the shape of the legs and elytra are evidently of a 

 sexual character only. 



The almost circular elytra and the strongly narrowed thorax 

 give this species a very distinct appearance ; when viewed from 

 above the elytra of the $ appear to be crenulated all round owing 

 to the sharp lateral granulation.

Long, c? 7f , $ 9 ; lat. c? 3f , $ 5 mm. 



Head transverse, slightly convex, rather coarsely striolato- 

 punctate, with thin pale pubescence ; forehead not impressed ; eyes 

 convex but not prominent. ^os^r«m distinctly longer than broad, 

 sides subparallel ; genre rounded and scarcely dilated, similar in the 

 two sexes ; upper surface plane, confluently punctured, trica,rinate, 

 the outer carinse straight and parallel. Anteiince (ilongate, piceous, 

 with pale grey pubescence ; scape compressed, distinctly sinuate 

 and gradually broadened from base to apex ; funicle with third 

 joint much longer than first, terminal joints elongate and distinctly 

 clavate. Frothorax distinctly transverse, subtruncate at base and 

 apex, narrow apically, sides slightly rounded, broadest rather before 

 middle ; upper surface subdepressed, closely set with low granules, 

 with a very shallow central furrov/ and a deep longitudinal im- 

 pressed line on each side of base ; colour black, v/ith ver}^ tliin pale
