yellow-white. The normal angular band on the abdomen varies 

 in depth of colour, from being hardly distinguishable to dark 

 brown or nearly black, and is most commonly divided longitudi- 

 nally by a pale or reddish stripe, and bordered with white. The 

 angulation of this band is a little different from that of 0. morio, 

 and in some examples the ground colour of the upper side is a 

 warm violet-brown, on which oblique lines of white dots are con- 

 spicuous, the dorsal band being crossed by three rows of white 

 tubercular denticulse. These examples, the dorsal band being 

 margined with white, are very handsome. 



The armature of the cephalothorax is very similar also to that 

 of 0. morio, but the denticulse, especially those in front of the 

 eye-eminence, are, though similarly placed, fewer in number and 

 less in size. 



The eye-eminence is small, and the teeth or denticulae on the 

 summit (5 9) are smaller than in 0. morio. The legs are rather 

 short and strong, pale brownish yellow, and devoid of spines or 

 denticulse. 



Examples of this species, which seems to belong to alpine or 

 northern districts, were sent to me from Scotland by Mr. H. C. 

 Young (formerly of Glasgow) and Sir Walter Elliott, and have 

 been examined by Mons. Simon. 



The shoiter and unarmed legs, and the fewer denticulae on the 

 caput, will probably render this species more easy to determine 

 than Oligoloplms alpinus.

 This abundant species is very variable in the colour and depth of 

 its markings. The ground colour is greyish white, often somewhat 

 silvery, and the markings vary from brown to reddish brown, 

 yellowish, black, and grey, and the abdomen is numerously studded
