366 Mr. Newport on the Class Myriapoda, Order Chilopoda. 



This species resembles L.forficatus, but is larger, and 1s distinguished from 

 it by the flattened form of the lip, with its straight margin, as well as by the 

 form of the dorsal plates. In the form of the labium and disposition of the 

 teeth it is allied to L. Sloanei, but differs from that species in the number of 

 teeth, and in the straight margins of the segments. It differs also from 

 L.pilicornis in the labium being flattened, polished, and entirely without 

 hairs. This species varies in having eleven instead of ten teeth. I am inclined 

 to believe that it is the L.spinipes of Say, as the spines on the legs are largely 

 developed. The size of the spines is the chief character assigned by Say to his 

 species ; but this is insufficient to distinguish it, as the articular spines, more 

 or less developed, are common to the whole genus. I have therefore described 

 it as a new species. The other characters given by Say to his species are also 

 common to the whole genus.

The characters of the labium and teeth of this species are very distinct. 

 The deep emargination is formed by the approximation of two slightly cres- 

 centric dental plates, set with strong, sharp, elongated teeth, which distinctly 

 indicate the predaceous habits of the species. The general characters of the 

 head, labium and teeth closely connect this species to L. variegatus. The 

 labium and mandibles are bright orange; head orange, mottled; the eyes 

 and sides of the face blackish, and the antennae annulated and pubescent. 

 The dorsal surface of the body is flattened and slightly rugose, and the legs 

 are naked, brownish yellow, with small articular spines.
