1906.] COLEOPTERA OF THE GENUS SCIOBIUS. 253 



narrow carina?, 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- 

 bisiniiate, sides rounded, broadest near base, broadly constricted 

 near apex, which is truncate and much nai-rower than the base ; 

 upper surface convex, closelj^ set with small depressed granules 

 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 5 , subdepressed in S , punctato-stiiate, with 

 the striae deeper laterally and containing rows of shallow punctures 

 separated by small granules, the dorsal intervals broad and almost 

 plane, smooth and coriaceous, the lateral ones subconvex, the 

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

 prominent in the $ , but inconspicuous in the J ; colour black, 

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

 thicker in the c? , piceous, with thin pale pubescence, the anterior 

 pairs of tibise broader and more strongly curved in the S . 



Types cS $ in the Stockholm Museum. 



PoNDOLAND : Port St. John {G. Shortridge). 



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

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

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

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

 sexual character only. 



The almost circular elyti-a and the strongly narrowed thorax 

 give this species a very distinct appearance ; wlien viewed from 

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

 to the sharp lateral granulation.

Long. (? 7f , 5 9; lat. ^ 3|, $ 5 mm. 



Head transverse, slightly convex, rather coarsely striolato- 

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

 convex but not prominent. Rostrurti distinctly longer than broad, 

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

 two sexes ; upper surface plane, confluentlj^ punctured, tricarinate, 

 the outer carinte straight and parallel. Antennce (Jongate, 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. Prothorax 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 furrow and a deep longitudinal im- 

 pressed line on each side of base ; colour black, with very thin pale
