Length two inches. Country? 
In the collection of the British Museum. 
The frontal segment of this species is flattened and punctured, 
with the posterior margin straight, and the anterior somewhat 
rounded; the mandibles are smooth, polished, rather straightened, 
and rounded, with the internal margin less acute, with two or three 
very small teeth; labium flattened, polished, with large, numerous 
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. 
Sub-Genus Necrophicophagus*, Newport. 
Geophilus**, Leach. 
Geophili longicornes, Gervais. 
Characters.—Frontal segment quadrate, a little longer than broad, 
with the angles obtuse ; antenne 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 ; /abiwm broad, 
almost quadrate, with the border emarginated ; body somewhat ta- 
pering; legs more than fifty pairs; preanal segment narrow, styles 
short. 
Species Necrophwophagus longicornis, Leach. 
Yellow, with the segments of the head, mandibles and labium 
dark ferruginous ; antenne 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 
Linnzeus. But Linnzeus’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 Gonibregmatus+, Newport. 
Characters.—Frontal segment short, transverse, anteriorly pointed ; 
* From yexeds, dead; @aaids, bark; and Péyw, to eat. 
+ From yale, angle, and Beéypa, the fore part of the head.
