 similar in colour and general armature to the legs; they terminate with a single, strong, sharply curved untoothed claw.

The falces are of a deep black red-brown colour, strong and prominent, and flat, but not cut away, on their inner sides; they are furnished on their upper sides with black bristles and yellowish-grey hairs, disposed in longitudinal lines; these bristles are strongest and most numerous on the inner margin of the upper side, increasing in strength forwards where, near the extremity, are some strong spines.

On the inner edge of the under side of each falx is a row of teeth, and each fang is also denticulate or finely serrate, beneath towards its hinder part.

The maxillæ are strong, cylindrical, and divergent; and each has a small bluntish angular prominence at the extremity on the inner side; their inner margin has a thick fringe of pale reddish hairs, the fore surface being clothed (as ordinarily) with dark bristly hairs, and there are a few black minute tooth-like spines in a line (sometimes in a small group) near the inner corner of their base.

The labium is short, broad, its breadth nearly double its length, and the upper corners rather rounded off; there are some strongish bristles, mostly towards the apex, but no tooth-like spines nor denticulations.

The sternum is oval, rather convex, broadest towards the hinder part, which is pointed at this extremity but hollow-truncate before.

The abdomen is sparingly clothed with hairs; it is of a stoutish regular oval form, and of a dull brownish yellow colour; its fore extremity on the upper side is thickly blotched with deep blackish-brown, and the
