Arachnida. 8565 



from the spinners ; the scalloping of the margins of this band 

 leaves two angular points on each side of it. The sides of the 

 abdomen towards the spinners have four or five rows of more or 

 less distinctly marked pale yellowish white spots, varying in 

 size; and now and then two or more spots are confluent: these 

 rows run obliquely backwards from the upper to the under side. 

 The under side, sternum and maxillae are clothed with hairs, 

 and of the same colour as the cephalothorax and legs. The 

 falces and labium are rather darker. 



Three females of this species were captured by myself, in June, 

 1862, running in bright sunshine on the sand-hills at Bournemouth, 

 in Hampshire ; but I was unable to discover the male. In the cha- 

 racter of the markings this spider bears some resemblance to Philo- 

 dromus elegans (Blackwall's ' British and Irish Spiders/ p. 94), but 

 may be easily distinguished by its paler and more "washed-out" 

 appearance, by the markings being all far less vivid, and by its shorter 

 and more robust form ; the bands on the cephalothorax differ from 

 those of P. elegans in being narrower, scalloped on the margins, 

 and so with several angular points on each side; the central band 

 also of the abdomen has, in P, elegans, only one angular point on 

 each side. This spider, which is also allied to Philodromus fallax 

 (Sundevall), is, I think, quite distinct from that species ; and though 

 far less striking looking than P. elegans, is yet a very distinctly 

 marked one. When at rest on the bare sand, with its legs extended, 

 it was quite invisible, and only caught the eye by its very rapid 

 movements, composed of sundry short runs. 



Philodromus hirstjtus. 



Female, adult. Length 3-twentieths of an inch. Length of cepha- 

 lothorax 1-twentieth. Relative length of legs, 4, 2, 3, 1. 



Cephalothorax of a dull yellowish drab-colour, sparingly clothed 

 with short brownish and yellowish hairs, amongst which are 

 some long black bristly nearly erect ones ; those on the fore- 

 head are very long and directed forwards. It has three longitu- 

 dinal bands, of a blackish brown colour — one, down the centre, 

 commences at the two centre eyes of the hinder row (which it 

 includes) ; it has the margins scalloped, and tapers to a point at 

 the hinder part of the cephalothorax : the other two bands com- 

 mence at .the outer eye on either side, and increase in breadth 

 towards the hinder part, where they end abruptly.
