Genera and Species o/Scolopendrida. 63 



Locality doubtful. The specimen was taken from a bottle 

 labelled ' India and S. America.' 



It is not easy to point out tlie affinities of this species, 

 because I am unable to determine its exact generic position. 

 In the sura of its characters, however, it seems to come 

 nearest to Scolopendra, although the head-plate does not 

 overlap the anterior portion of the first tergite. One of its 

 most marked features is the great stoutness of the anal legs. 



Cormocephalus Willsii^ sp. n. 



Body robust and parallel-sided. 



Colour olivaceous or ochraceous, head and anal tergite 

 ferrugineous ; shining. 



Head-plate convex, wider than long, coarsely punctured, 

 with two posterior diverging sulci. 



Antennm of moderate length, composed of seventeen seg- 

 ments, whereof the basal eight are bare, the rest pubescent. 



Maxillary sternite coarsely punctured, slightly depressed 

 and striated in the middle line, marked in front with trans- 

 verse, more or less branching strife and a short median longi- 

 tudinal stria ; prosternal plates well developed, parallel, almost 

 in contact, each armed w'ith four or five conspicuous teeth ; 

 maxillary feet also coarsely punctured, with a well-developed 

 basal subdentate tooth. 



Tergites. — First coarsely punctured, not sulcate ; the second 

 with two very faint abbreviated sulci ; the third with the sulci 

 still incomplete ; the fourth to the twentieth completely bisul- 

 cate ; the seventh to the twentieth marginate and lightly 

 wrinkled laterally, all of them punctured. 

 Stermtes smooth, punctured, bisulcate. 

 Anal somite.— Tergite not marked by a median sulcus; 

 pleurce coarsely porous, the process well-developed and termi- 

 nated by two spines, one spine in the middle of the hinder 

 border ; sternite much narrowed posteriorly, with straight 

 hinder border; legs somewhat short, moderately slender; 

 femur armed with about eleven strong spines (not including 

 the process, which is well developed and bifid), three or four 

 on the inner surface, two on the under inner edge, and four or 

 five in two longitudinal series on the under outer edge ; claws 

 not basally spurred. 



Legs with first tarsal segment unarmed ; claws furnished 

 basally with two spurs.
