Genera and Species of Scolopendridas. 65 



segment ; tarsal segments short and cylindrical ; claw small, 

 short, not interiorly serrate, without spurs. 



Legs with tarsi unspined ; claws with two basal spurs. 



Length 43 millim. 



Two specimens from Natal, collected by Gueinzius. 



In the thickness of its anal legs this species resembles 

 Cupipes. 1 refer it, however, to Cormocepkalus for the fol- 

 lowing reasons : — There are no sulci on the first tergite, the 

 anal pleurse are provided with a short process, the spine- 

 armature of the anal femora is like that of a typical Cormo- 

 cepkalus, and the claw of the anal leg is not serrate beneath 

 and small, being shorter than the first tarsal segment of this 

 appendage. 



Of the South- African species already described it perhaps 

 comes nearest to C. rugulosus, Porath. But this form, as its 

 name implies, is rugulose. Moreover, judging from Dr. 

 Porath's description, which makes no mention of any pecu- 

 liarity in the structure of the anal legs, these appendages are 

 normally formed in his species. 



Cormocepkalus inermipes, sp. n. (PI. IV. fig?. 9, 9 a.) 



Body moderately robust, parallel-sided. 



Colour (dry specimen) olivaceous, with metallic lustre. 



Head-plate cordate, slightly wider than long, somewhat 

 coarsely punctured, with two posterior anteriorly diverging 

 sulci. 



Antennae short, slender, attenuate, composed of seventeen 

 segments, whereof the basal six are naked, the rest pubescent. 



Maxillary sternite wide, entire, and coarsely punctured ; 

 prosternal plates widely separated, each furnished with four 

 teeth, one external, separate, and posterior, three internal, 

 fused and projecting — the distance between the plates is almost 

 equal to the width of one of them ; basal tooth prominent and 

 subdentate. 



Tergites punctured, smooth, from the second strongly bisul- 

 cate, from the fifth or sixth marginate. 



Sternites smooth, strongly bisulcate. 



Anal somite. — Tergite much wider than long, marked in 

 its posterior half with a faint longitudinal sulcus ; pleura?, 

 closely porous, the process long, slender, and tipped with 

 two strong spines ; no lateral or superior spines present ; 

 sternite much narrowed posteriorly, with straight hinder 

 border ; legs moderately long and very stout, almost in con- 

 tact ; femur not twice as long as it is wide, armed with nine 

 or ten spines (not including the process) — one on. the upper
