entirely pale, while the tibia and femur are infuscate, as in 
those species. 
Genus SOLPUGA. 
Solpuga ferox, sp.n. (Pl. IV. fig. 3.) 
? .—Colour. Cephalic plate, mandibles, and appendages 
reddish yellow ; abdominal terga pale yellow, the membrane 
at the sides of the plates and between them slightly infuscate. 
Cephalic plate in width a little greater than the length of 
the tibia of the palpus and a little less than the length of the 
tarsus and protarsus of that appendage; width of ocular 
tubercle about» equalling the length of the tarsus of palp ; 
distance between eyes less than a diameter. 
Mandibles furnished inside with nine or ten ridges, which 
inferiorly decrease in length; the upper jaw armed distally 
with 3 large conical subequal teeth, between the second and 
third of which there are two smaller teeth, of which the poste- 
rior is much larger than the anterior; this jaw is armed behind 
with an external series consisting of 4 teeth and an internal 
consisting of 3, of which the anterior is long and stout; lower 
jaw armed with 3 teeth, of which the first and third are sub- 
ena and the second situated upon the base of the third 
mall. 
Palpi moderately long and slender ; femur furnished below 
with long sete; tibia also furnished below with long sete 
and thickly clothed above and below with short erect hairs ; 
protarsus, which is attenuate in its distal half, clothed like the 
tibia, but its lower surface is furnished with a number ot 
erect short truncate hairs, which may have resulted from the 
breaking of the long sete. 
Legs of first pair clothed with short close-set hairs and 
long slender sete ; those of second pair covered with fine hairs 
above, and on the lower surface of the tibia with sete which 
increase in stoutness towards the distal end of the segment, 
the distal pair being stout and spiniform; this segment is 
armed above with a single stout distal spine ; the protarsus 
armed above with five strong spines and below in its distal 
half with two spines behind and three in front ; tarsus armed 
below with seven pairs of spines—four pairs on the first and 
one pair upon the second, third, and fourth segments, of which 
those of the third to fifth pairs are the strongest ; third leg 
resembling the second, except that there are two spines on 
the upperside of the tibia, and the interval between the third 
and fourth spines on the upperside of the protarsus is greater 
than in the second leg, and the segment is armed below with
