NEW SPECIES OF EURO-1'EAN SPTDERS.

marking, narrowly margined with whitish, obtusely enlarged on either 

 side a little past its middle point ; and its hinder extremity draws in sud- 

 denly, and then terminates narrowly, tapering to a sharp point ; from 

 either corner, where it draws in, there is an oblique, short, dark dash, 

 forming the anterior boundary of abroad tapering band, which reaches 

 to the spinners, and is of a dark yellow-brown colour, having several 

 deeper angular lines along its middle ; the sides and underside are 

 brownish yellow, the former rather the darkest. The genital aper- 

 ture is of a somewhat oblong form, wider behind than in front, with 

 dark, shining, reddish-brown, lateral margins. 

 The armature of the abdomen will distinguish this spider at 

 once from Philoclromiis (Araneus) formicinas (Clk.), as also will the 

 form of the large marking on the fore part of the upperside as 

 well as the character of the other markings ; it has no lateral black 

 or dark patch, as in P. setigems, from which also other peculiarities 

 (as above noticed) separate it. 



A single example of this very interesting spiderwas kindly brought 

 to me from Mentone in March 1867 by H. T. Stainton, Esq. 



Genus^PniLODROMTTS (Walck.). 



Philodromus torquatus, sp. n. PI. XV. fig. 12. 

 Adult male, If line. 



This species is allied to P. aureolus (Walck.), but its much smaller size, 

 as well as its strikingly different colours and the structure of the palpi, 

 will serve to make it easily distinguishable in the adult state. 



The cephalothorax is of the ordinary form, the clypeus projecting and 

 exceeding in height half that of the facial space : the sides and cly- 

 peus are of a deep, rich, black chestnut-brown, leaving a broad lon- 

 gitudinal space on the upperside ; the hinder half of the space is of 

 a brownish-yellow colour, slightly mottled with a darker line ; on the 

 fore half there is a large crescent-formed, collar-like, pale cream- 

 coloured marking ; its convexity is directed backwards ; and it has two 

 dark blotches, one near each horn of the crescent, and two small dark 

 spots in a short transverse line near its hinder extremity ; between this 

 and the eyes the colour is like that of the eye-area and clypeus, with 

 a pale brownish-yellow band along the middle, having its posterior 

 termination in the extreme concavity of the crescent above mentioned ; 

 this band has on it two parallel, longitudinal, dark-brown lines. 



The eyes are small, very nearly of equal size, and in the ordinary posi- 

 tion, but forming a rather narrower (and so longer) crescent-formed 

 figure ; six of them form a long transverse curved row ; and between 

 the two extreme eyes of this row, but within the straight line formed 

 by them, are two more ; these two are further from each other
