_Cephalothorax_ oval, truncated and almost equally broad at each end; the upper surface is moderately convex, the caput elevated a little above the rest, and equally rounded on the sides and upper part; the profile of the whole cephalothorax forms a general sloping slightly curved line, broken by the thoracic junctional pit or fovea, which is narrow but strong, and gently but equally curved, the convexity of the curve directed forwards; the thorax next to this fovea is rather gibbous, but not over any great extent of surface; the other normal indentations are tolerably strong; the colour of the cephalothorax is yellow-brown, darkest on the sides of the caput, and along the thoracic indentations, palest on the margins, forming a pale marginal border indistinctly vandyked on the inner edge. The surface is clothed, but not densely, with yellowish-grey adpressed hairs; there are a few black bristles in a straight transverse line, directed forwards from the lower margin of the clypeus; also a few more bristles curved and of various lengths before and behind the ocular area, their points meeting over this area, and a row of strong, nearly erect ones in a longitudinal central line from the ocular area to the junctional fovea; besides these are a few more, finer and less conspicuous, along the middle both of the caput and thorax; the colour on either side and in front of the ocular area is orange yellow-brown, and joining with this a broad band of the same runs backwards from the ocular area to the thoracic fovea. The band begins as wide as this area, it then directly enlarges a little, and thence tapers slightly and gradually to its termination, forming a truncate wedge, with the margins rather irregular, but on the whole a little curved. This band is not immaculate, there being two dark yellow-brown tapering lines or bars along the greater part of its length; these bars begin from each outer pair of eyes of the hinder row, and tapering to a fine line, converge to the thoracic fovea, but do not quite meet. It is important to note the exact form and distribution of the central band and these tapering bars, as their differences from the character of the similar part in another closely allied species are strongly specific; the above description holds good in above twenty examples before me.
