(Plate XLII. fig. 8.) Male adult, length 4J lines. In general proportions, form, and appearance this species does not vary from the ordinary types of the genus, differing chiefly in the pattern formed by the distribution of its colours and markings, and in the structure of the palpi and their peculiar organs. The cephalothorax is of a dark brown colour tinged with yellow, and furnished sparingly with yellowish and other hairs; it is margined narrowly with a blackish line, above which is a broken band of yellow, in some individuals almost obsolete, in others consisting of broken-edged detached spots; the central median line of the cephalothorax is occupied by a well-defined yellow band of a peculiar form; commencing narrowly between the eyes it enlarges suddenly into a nearly square form, behind which it narrows abruptly again into a neck, whence it continues in a spear-head form with the point directed backwards; this spear-head portion encloses the point of junction of the cephalic and thoracic segments, which is marked by a short dark longitudinal line; the fore part of this central longitudinal band is marked with some brown spots and markings; and the junctions of the thoracic segments are also marked by converging lateral lines of dark brown; the immediate region of the eyes is black. Some variety exists in different individuals in the exact form of the central band, but its general character is similar in all that have come under m y notice. Of the four eyes forming the large hinder square, the two fore ones are the largest and much nearer together than the two hinder ones ; of the four forming the front line, the two centrals are the smallest; this line is equal in length to that formed by the two fore ones of the posterior square, and the four are about equidistant from each other. Legs and palpi yellow, banded with dark brown, and furnished with hairs, bristles, and spines; the relative length of the legs is 4, 1, 2, 3; the tibiae, especially of the hinder pair, are conspicuous and characteristic from being of a deep brown colour, with a broad- |
