SOLPUGA SPECTRALIS, n. Sp. 



(Fig. 25.) 



$ . Flagcllum reaching back beyond the middle of the mandible, 

 passing close above the basal enlargement,* the latter shaped as in 

 S. villosa ; the anterior bend short and sharp, remote from the apex 

 of the fang and situated some distance behind the distal group of 

 teeth. Recurrent portion tapering distally to a filiform apex ; the 

 distal half much flattened from the sides, finely and deeply serrated 

 along its upper edge, the lower edge thin but entire. 



Upper jaio of mandibles with three distal teeth close together, of 

 which the first is very small, triangular and keel-like, the second 

 long and pointed, the third large and bifid at the apex ; then follows 

 a long, strongly concave, toothless interval, and finally a very long 

 tooth immediately preceded by a very minute denticle; the posterior 

 double series runs almost at right angles to the distal series. 

 Terminal fang long, inclining slightly downwards from the base for 

 about half its length, then sub-horizontal and curved outwards till 

 near the apex, which is bent downwards ; the upper surface pro- 

 vided along the inner edge throughout more than half the length of 

 the free part before the flagellum with a very high keel, situated 

 over the distal group of teeth, the upper edge of the keel slightly 

 irregular but not toothed ; at the commencement of the bend the 

 flagellum is situated in the middle of the upper surface of the fang, 

 and occupies almost the entire width. Lower jaw with two strong- 

 teeth and a small one just midway between them, the upper surface 

 not grooved or keeled laterally in the toothed region. 



Colour. Legs and the upper surface of the body ferruginous, 

 the mandibles paler, yellowish brown above, under surface of 

 mandibles, of body, and of the basal joints of the legs pale 

 yellowish. Legs and palps distally darker and ferruginous-black. 

 The thorax, abdomen, and the three hind pairs of legs very densely 

 covered with long soft hairs, those on the thorax and the anterior 

 abdominal terga whitish brown in colour, the rest white ; those on 

 the hind leg enormously long and very numerous, but not forming 

 a mane, the single hairs much longer than the metatarsus ; on the 

 posterior end of the abdomen above are a few r black hairs. The 

 bristles on the head-plate and mandibles brown, as are also most of 

 the hairs on the palps. Malleoli black-edged. 



Measurements. Total length 28 ; length of head-plate 5, width 6; 



* As the specimen is dried, the flagellum may have been more erect in the 

 living animal.
