This species differs from all the South- African forms 

 described by Porath in not having the anal tergite marked by 

 a longitudinal sulcus. This I believe is the first record of 

 the genus from Madagascar. 



CormocepJialus cupipes^ sp. n. (PI. IV. fig. 8.) 



Body slender, widest at its posterior end. 



Colour (dry specimens) olivaceo-ochraceous above ; under 

 surface and maxillary sternite much paler ; antennae and 

 distal segments of the legs olivaceous. 



Head-plate elongate, ovate, slightly longer than wide, 

 sparsely but somewhat coarsely punctured, marked in its 

 posterior half by two anteriorly diverging sulci. 



Antennae long and slender, composed of seventeen seg- 

 ments, whereof the basal six are naked and the rest pubescent. 



Maxillary sternite sparsely but coarsely punctured ; pro- 

 sternal plates elongate, in contact, each bearing four well- 

 defined sharp teeth ; basal tooth long, sharp, and subdentate. 



TergiteSj except the first and last, conspicuously bisulcate, 

 from the fifth or sixth marginate. 



Sternites strongly bisulcate and furnished in addition in 

 the anterior portion of the middle with a median longitudinal 

 impression. 



Anal somite. — Tergite with a conspicuous median sulcus, 

 wider than long, its posterior border evenly convex and not 

 produced in the middle ; pleurce very narrow, coarsely punc- 

 tured, the process very short, conical, and bearing two apical 

 spines ; there are no lateral or superior spines ; sternite long 

 and narrow, nearly twice as long as the basal width, with a 

 conspicuous median longitudinal impression ; legs very short 

 and very stout, not very much longer than those of the 

 twentieth somite, stout at the base and evenly attenuated 

 towards the apex, very coarsely punctured, the three basal 

 segments more or less flattened above, with feebly developed 

 posterior marginal notches, the two femora together nearly as 

 wide as the tergite, in contact throughout in the middle line, 

 each armed with three spines in an irregular series on 

 the upper inner edge, two on the inner surface, two on 

 the under inner edge, and four in two series on the under 

 outer edge ; the process short, conical, and tipped with two 

 spines ; the median part of the under surface without spines 

 and markedly excavated in front ; patella rounded laterally 

 and beneath ; tibia with its upper surface bearing two longi- 

 tudinal depressions separated by a median ridge ; in one speci- 

 men there is a depression on the inner surface of this same
