KEY. O. P. CAMBBLDGE ON SOME 



strcmgish apophyses from its extremity, one on the outer side obtusely 

 and roundly pointed at its termination, and shorter than the correspond- 

 ing one in X. cristatus; the other, rather near it, but below, towards 

 the underside of the joint, is the largest and a little the longest, slightly 

 curved and squarely truncate at its extremity : the digital joint is 

 rather smaller in proportion than in X. cristatus, and is prominent 

 near the middle of its outer side, but wants the pale process there so 

 strongly marked in that species ; at least, this process in the present 

 species is quite rudimentary : the palpal organs are well developed but 

 simple, and entirely wanting the conspicuous, prominent, corneous, 

 spiny processes so notable in X. cristatus (and other nearly allied 

 species) ; they appear to consist merely of a large not very convex 

 corneous lobe, with two or three inconspicuous, slightly curved, sharp- 

 pointed spines near their fore extremity ; the inner margin of the pal- 

 pal organs is black, and either of a corneous fillet-like nature, or else 

 this appearance arises from a closely fitting spine running round it ; 

 it was difficult to ascertain exactly which. 

 An adult female found at the same time and place so exactly 

 resembles the normal X. audax and some varieties of JC. cristatus, 

 that possibly it may not be the female of the present species ; no 

 doubt, however, it will be very difficult to distinguish this sex 

 from that of the two before-mentioned species. 



The single male described was found by myself in June 1865 

 running actively on a bare spot on the mountain-side at Bruck 

 am Main in Austria. 



Genus Monastes (Luc.). 

 Monastes Staintoni, sp. n. PI. XV. fig. 10. 

 Female (not quite adult), length 3^ lines (nearly). 



The cephalothorax, when looked at from above, is nearly round, truncate, 

 and a little produced in front ; it is moderately convex above ; and 

 the clypeus, which equals half the facial space in height, is very broad 

 and projects considerably forwards at its lower margin, where there is 

 a single transverse row of prominent bristles ; the normal grooves and 

 indentations are well marked ; and there are a few prominent black 

 bristles on the upper part : the colour is a pale greyish yellow-brown 

 mottled with white, and spotted with small black spots. 



The eyes are on large roundish tubercles, in two transverse, nearly par- 

 allel, slightly curved rows, of which the hinder is much longer than the 

 front row ; the two central eyes of the hinder row are nearer together 

 than each is to the lateral of the same row on its side ; and the same 

 may be said of the two fore central eyes ; the two end eyes of the 

 hinder row on each side, with the fore lateral nearest to them, form 

 an equilateral triangle.
