386 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [June 2, 



The fakes 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 btjlbifer, 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 au 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
