Immature female, length 7-1/2 lines (15-1/2 mm.).

Although no example was quite adult, this species may readily be distinguished from all others yet known to me, by its more elongated form, particularly the cylindrico-ovate form of the abdomen.

The cephalothorax is oval, broadest towards its posterior extremity, where it is rounded, the fore-margin being truncated; the caput is well rounded and convex, and the thorax perhaps more so than in other species, so that when looked at in profile there is a considerable dip or hollow at the thoracic fovea; this fovea forms a slight curve. Except that the lateral margins are rather broadly pale towards the hinder part (though the pale portion is ill-defined), the whole of the cephalothorax is of a uniform dull yellowish-brown colour; the extreme lateral margin is marked by a black line, and in one or two examples there was an indistinct yellowish central longitudinal line from the eyes to the thoracic junction, having a single row of prominent bristles upon it. The whole surface of the cephalothorax is fairly clothed with dusky yellowish-grey adpressed hairs: the ordinary grooves and indentations are well marked.

The eyes are on the usual eye eminence, which is perhaps rather more elevated than ordinary, and its summit black; their position is ordinary. It may, however, be noticed that the fore-centrals are placed more forward than in most of the other known species; the fore-centrals are about equally separated from each other, and from the fore-laterals nearest to each respectively; they are also separated from the hind
