Colour (dry specimen) almost uniformly dark ochraceous, the ocular tubercle and the anterior border of the cephalothorax black. Cephalothorax thickly and somewhat coarsely granular throughout, without trace of keels; its anterior border lightly emarginate ; the ocular tubercle deeply and widely cleft, granular in front and behind, smooth in the middle; the post-ocular sulcus deep and T-shaped. Tergites closely granular throughout, the granulation coarser in the posterior half; the first six furnished with a conspicuous median granular keel; the fourth, fifth, and sixth, in addition, with traces of short lateral keels, formed of two or three large granules set in longitudinal series ; the seventh tergite furnished with an anterior median, granular, subcarinate prominence, and two lateral, long, conspicuously denticulated keels, which behind almost attain the posterior margin, and in front are more or less connected by a transverse row of stronger granules. Sternites: the first four smooth, sparsely puuctured and bisulcate; the fifth furnished with four obsolete, subgranular keels. Tail long and nearly parallel-sided ; the first four segments hollowed above and minutely granular; the first three furnished with ten keels, the fourth with eight; the superior keels on the first four denticulate, with the posterior denticle the largest; the superior lateral keel on these same segments also denticulate, but with the terminal denticle only enlarged on the first and second; the median lateral keel is also denticulate, but less strongly than those just described-it is complete on the first segment, slightly abbreviated in front on the second, and slightly more abbreviated on the third, on the fourth its position is occupied by a few small granules ; the inferior keels are strong and denticulated on the first four segments, but a little less strongly denticulated on the first than on the second, on the second than on the third, and on the third than on the fourth : the fifth segment minutely and closely granular and shallowly excavated above, with no conspicuous posterior depression and no superior keels, laterally more coarsely granular; the three inferior keels strong and complete and evenly denticulated throughout; the spaces between these keels furnished with strong granules, which in the anterior half of the segment are on each side of the middle line arranged iu a definite longitudinal series. Vesicle of moderate size, sparsely but distinctly tubercular beneath, without a spine or enlarged tubercle beneath the aculeus, which is of moderate length and gently curved. Palpi distinctly hairy, especially on the brachium, manus, and dactyli; humerus finely granular above and below, tubercular in front, the keels normal, distinct and strongly granular ; brachium not costate, rounded and smooth behind and below, granular above, granular and tubercular in front; manus rounded, neither carinate nor granular, slightly wider than the brachium ; dactyli short, both slightly sinuate ; the armature of the dactyli closely resembling that |
