Since the above description of the female of this species was written, an example of the adult male has been most opportunely discovered. It is much smaller than the female, its length being only six lines. The _Cephalothorax_ is of an uniform clear yellow-brown colour, tinged with orange, and thinly clothed with a greyish pubescence: the oblique indentations marking the union of the cephalic and thoracic segments are indicated by a strongish black-brown band on either side, which becomes obsolete as each approaches the other near the central curved indentation; there are also two or three converging suffused blackish stripes on the hinder slope. The relative length of the _Legs_ is the same in both sexes, 4, 1, 2, 3, but in the male those of the fourth are longer in proportion to those of the third pair than in the female; the spines also on the legs are more numerous and stronger, the upper sides of the femora of all the legs are deeply suffused with black, while in the female this suffusion is not nearly of so marked a character, though the genua of the different females examined had a strong brown-black macula on the outer side of each, while the corresponding maculæ in the single male examined were but just visible; the three spines observed on the outer side of the genua of the third pair of legs in the female are of even a more marked character in the male, and hence they may be considered a good and tangible specific difference from other nearly allied species; the tibiæ of the first pair are considerably enlarged on the under side at the fore extremity, where each is armed with a single, longish, strong, slightly curved, pointed black spine directed forwards (fig. _a_, 3). The _Abdomen_ is small and of an oval form; its colours and markings resemble those of the female, but on the hinder half of the upper side two or three indistinctly traced pale angular bars or chevrons are formed by the distribution of the black-brown colours and markings; the under side of the abdomen is of a uniform pale whitish yellow, except the spiracular plates, which are yellow-brown. The _Palpi_ are moderately long and strong; the radial joint is longer than the cubital, and is of a tumid and somewhat oval form, suffused over most of its surface with dark brown, the rest of the palpus being of a yellowish-brown colour; the digital joint is small and somewhat oblong-oval, curved downwards, and very slightly concave on its inside; the palpal organs consist of a nearly globular, basal, corneous bulb prolonged into a strongish, curved, but not very long, pear-stem form, the stem being distinctly cleft or bifid at its extreme point (_vide_ figs. _a_ 1, and _a_ 2), one portion of the bifid part is larger than the other, though both are equal in length, and the stem of the palpal bulb is directed transversely outwards, almost at right angles with the digital joint.
