Length of the female, §ths of an inch ; length of the cephalo-thorax, J,ths, breadth, gth; 
breadth of the abdomen, Jth ; length of a leg of the second pair, fths; length of a leg of 
the third pair, fths. 
The eyes constitute a segment of a circle, with its convexity directed forwards; the 
lateral eyes of the anterior row are the largest, and the intermediate ones of the same row are 
the smallest of the eight. The cephalo-thorax is compressed before, rounded on the sides, 
convex, with slight furrows converging from the lateral margins towards the middle. The 
falces are powerful, conical, vertical, and armed with teeth on the inner surface. The lip is 
semicircular; and the sternum is heart-shaped. The legs are provided with hairs and sessile 
spines; the second pair is the longest, then the fourth, and the third pair is the shortest; the 
metatarsi and tarsi have hair-like papillae distributed upon their inferior surface, and the latter 
are terminated by two curved, deeply pectinated claws, below which there is a small scopula. 
The palpi are robust, and have a minute, curved, pectinated claw at their extremity. The 
abdomen is of an oblong-oviform figure, sparingly clothed with short hairs, convex above, 
projecting over the base of the cephalo-thorax. The colour of this sex is green; the 
abdomen, which is paler than the cephalo-thorax, has a band of a deeper hue extending from 
the anterior extremity along the middle of the upper part, about half of its length, and termi¬ 
nating in a point; the sexual organs are large, glossy, with a septum in the middle, and are 
of a very dark, reddish-brown colour. 
When immature, the male resembles the female in colour, but in the adult state it differs 
from her remarkably; it is smaller, and the abdomen, which is of a yellow colour above, has 
three bands of a fine red tint extending from its anterior to its posterior extremity, one 
situated in the middle and another on each side ; underneath, it is of a dull-green hue. The 
radial joint of the palpi projects a long, pointed, red-brown apophysis from its extremity, in 
front; the digital joint is oval, convex and hairy externally, concave within, comprising the 
palpal organs, which are highly developed, of a reddish-brown colour, and are terminated b) 
a curved, pointed spine.
