colour is a coppeiy yellow, bounded by a blackish line, and 

 suflFused, especially on the sides and in the furrows, with olive- 

 brown. 



Eyes eight, in two almost concentric curved rows on the front 

 of the cephalothorax, the curve directed backwards; they are 

 nearly equal in size, the two middle ones of the foremost row 

 rather the smallest, and nearer together than the middle ones of 

 the hinder row, which last two are further from each other than 

 from the one at the end of the row nearest to each ; the front 

 row is immediately above the frontal margin. 



Legs very long and strap-like, i. e. deeper than broad ; this is 

 very observable in the femoral joint. Colour clear coppery yellow; 

 the first and second pairs have the genual, tibial, and tarsal 

 joints, and the third and fourth pairs the tibial and metatarsal 

 joints, suffused with greenish brown. They are furnished with 

 longish hairs and spines; these spines are in two parallel rows 

 on the under side of the tibial and metatarsal joints of the first 

 and second pairs, but are longest on the third and fourth pairs, 

 though not placed regularly as on the other legs. 



Palpi same colour as the legs, slightly suffused with brown ; 

 radial joint larger than the cubital, and having a short black spiny 

 projection at its extremity on the outer side; digital joint small, 

 oval, convex, and hairy outside; palpal organs simple in struc- 

 ture and moderately developed, with a small black spine at their 

 extremity. 



Falces conical, vertical, with a few minute teeth on the inner 

 surface. 



Maxilla convex at the base, rounded at the extremity, and 

 inclined towards the labium, but not curved inwardly. 



Labium nearly quadrate, dark brownish yellow, slightly paler 

 at the top. 



Sternum oval, and, with the maxillae and falces, of a yellow- 

 brown colour, but not so dark as the labium. 



Abdomen slightly hairy, oblong, squarish at the end nearest 

 the cephalothorax, over which it projects a little, but rounder at 

 the other end. Colour of the upper part dark olive-brown with 

 a greenish tinge ; several clear yellow angulated lines or chev- 

 rons (the points of the angles directed forwards) begin at the 

 spinners and extend about halfway to the cephalothorax, in- 

 creasing in span as they approach it ; under side rather paler 

 than the upper ; branchial opercula yellowish white. 



The adult female resembles the male, though slightly smaller, 

 and the actual length of her legs is less ; the sexual organs are 

 of a reddish colour; when immature, her legs are blotched and 

 annulated with dark brown. 



Three adult males and an adult female of this species were
