Mr. G. Newport on some new Genera of Myriapoda. 501 



and deeply impressed punctures, and a longitudinal median sulcus, 

 with a slight emargination ; dorsal surface of the body with three 

 longitudinal sulci ; anal styles five-jointed ; second and third joint 

 short, but the fourth and fifth longer. 



The characters of this species are less strongly marked than in 

 others of this genus, and they seem to form a transition to those of 

 the next genus. The anal styles are still very distinctly organs of 

 locomotion, in which respect they resemble those of Scolopendra and 

 Cryptops. 



Subgenus Necrophlccophagus* , Newport. 



Geophilus**, Leach. 



Geophili longicornes, Gervais. 



Characters. — Frontal segment quadrate, a little longer than broad, 

 with the angles obtuse ; antennae inserted on the front, sub-approxi- 

 mated, more than three times as long as the frontal segment, with 

 the joints twice as long as broad, conic ; basilar segment short, with 

 the posterior margin much wider than the frontal ; mandibles short, 

 strong, with the internal margin rounded, toothless ; labium broad, 

 almost quadrate, with the border emarginated ; body somewhat ta- 

 pering ; legs more than fifty pairs ; preanal segment narrow, styles 

 short. 



Species Necrophlveophagus longicornis, Leach. 



Yellow, with the segments of the head, mandibles and labium 

 dark ferruginous ; antennae hairy, four times as long as the frontal 

 segment, with the three or four terminal joints smaller than the 

 others ; labium smooth, with minute punctures, subconic ; anteriorly 

 wide and almost straight, posteriorly rounded ; legs yellow, fifty- five 

 pairs, anal styles small, slightly hairy. 



Length two and a half to three inches. Europe : very common. 



I have retained Dr. Leach's original name to this species, which 

 has been supposed by M. Gervais to be the Scolopendra electrica of 

 Linnaeus. ButLinnseus's species is described as " pedibus utrinque 70;" 

 while Leach's species, of which there are four specimens in the ca- 

 binet at the British Museum, besides ten collected by other persons, 

 has at most only fifty-five. 



Genus Gonibregmatusf, Newport. 

 Characters. — Frontal segment short, transverse, anteriorly pointed ; 

 basilar segment very short, wider than the frontal ; antenna monili- 

 form, approximated at their base, joints very short, with the terminal 

 one slightly elongated ; eyes absent ; mandibles very slender, long, 

 pointed, arcuate, toothless, compressed and twisted near their base ; 

 labium very short, transverse, with the anterior border slightly pro- 

 duced and emarginated ; labium internum projecting, thick, folded, and 

 formed for sucking ; palpi with the terminal joints slender and acute ; 

 sub-basilar segment short, but larger than the basilar; body elon- 

 gated, segments more than 160; legs inserted into little foveolae in
