ago, and another more recently in Wicken Fen, Cambridgeshire. 

 The former example has been examined by M. Simon, who tells 

 me that it is identical with Hyctia nivoyi, Luc. 



HYCTIA (?) XANTHOGRAMMA. 



SALTIOUS XANTHOGRAMMA, Blachw., l.C, p. 51. 



This spider is only known from the very short description 

 quoted by Mr. Blackwall (I.e.) from "Martin Lister" (Hist. 

 Animal Angl. De Aran., p. 90). The following are the most 

 important points of this description : — Of medium size, mostly 

 yellowish. Cophalo-thorax large, nearly quadrate, very flat, 

 broadest in front. Eyes emerald green. Abdomen subcylindrical, 

 pointed behind, with three conspicuous saffron-coloured streaks 

 in the medial line of the upper side ; under part whitish. First 

 pair of legs robust, hairy, and longer than the rest ; third pair 

 shortest ; digital joints tumid and much like the falces, which 

 are reddish black. 



No locality is given for this spider, which is evidently of a 

 very distinct species, and probably of the genus Hyctia, Sim. 



GENUS PHILffiUS, Thor. 



The cephalo-thorax in this genus is very elevated, the thoracic 

 portion dilated, and at least one half longer than the caput, the 

 upper part of which is level or slightly convex. Falces strong, 

 long, and often a littlo divergent in the males. Legs in the 

 male 1.2.4.3., in the female 4.1.3.2. ; those of first pair strongest. 



The difference in form, colours, and markings between the 

 sexes in this genus is extraordinary. The greater number of the 

 species are exotic ; one only claims to be British. 



The activity of the male is very great, leaping on the face of 

 rocks or among heaps of stones, &c, to an almost inconceivable 

 extent.
