Show 386 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, The falces are neither very long nor strong; they are straight and nearly vertical, and of a dark reddish-brown colour. The maxilla and labium are normal in form, and of a deep blackish-brown colour, the former tipped with pale yellowish. The sternum is oval and similar in colour to the cephalothorax. The abdomen is of an oblong form; its colour is black-brown; and it has a pale transverse band at its fore margin, clothed with white hairs ; behind this on either side is an indistinct suffused patch of pale yellowish red-brown, and behind again, about the middle of the length of the abdomen, is on each side another pale yellowish-brown tapering stripe running over the side and with its pointed extremity directed backwards; these last two stripes do not meet in the middle of the abdomen, but they are clothed with white hairs; just above the spinners also is a transverse, somewhat crescent-shaped band of white hairs. A large squarish area next to the spiracular plates on the underside is of a pale dusky drab colour, those plates as well as the space between them being similar in colour to the cephalothorax. A single adult male from Italy ; the precise locality unknown, but believed to be near Naples. DRASSUS BULBIFER, sp. n. (Plate LI. fig. 13.) Adult male, length 2 lines. The cephalothorax of this very distinct species is of a bright reddish yellow-brown colour, with the margins and normal grooves and indentations marked with black ; it is of ordinary form. When looked at in profile, the occiput is roundish and rather higher than either the thoracic junction or the ocular area; this latter portion is almost all black ; the height of the clypeus (which retreats a little) is about one third that of the facial space. The eyes are of moderate size and not very unequal to each other ; they are in two transverse rows (the front row shortest), slightly curved from each other, forming an oblong figure, whose length at its longest part is rather more than double its width at the widest part; the four eyes of the hinder row are about equal in size, pearly white, and equidistant from each other, the intervals, if any thing, rather exceeding an eye's diameter. The fore central eyes are rather smaller (being the smallest of the eight), but form a line equal in length to the hind centrals, the interval between them being greater than an eye's diameter ; and each of them is very close, but not quite contiguous, to the fore lateral on its side; the interval between each fore lateral and the hind lateral on its side is about equal to the diameter of the latter; while the interval between each fore central and the hind lateral nearest to it is about equal to two diameters of the former. The legs (in the only example examined) were much mutilated, but they appeared to be undoubtedly long and strong ; their relative length 4, 1, 2, 3; they are yellow ; the femora of the first and second pairs are black, furnished with hairs, and there are some spines on those of the third and fourth pairs; the terminal tarsal claws on |
