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
