41 6 ARACHNIDA ARANEAE 



CHAP. 



(ii.) The AGELENINAE also contain sixteen genera, but it is a 

 much larger group, some of the genera being rich in species. 

 They are mostly moderate or large-size'd hairy spiders, living in 

 temperate or cold climates. There are about fifty species of 

 Tegenaria, seven of which have been recorded as British. 



Our commonest Cellar-spider is T. derhamii, but the very 

 large long-legged species found in houses in the southern counties 

 of England is T. parietina ( = guyonii = domestica). There are 

 not many species of Agelena, but one, A. labyrinthica, is a common 

 object in this country, with its large, close-textured web and 

 accompanying tube spread on grassy banks by the wayside. 

 Coelotes atropos is a formidable-looking spider, found occasionally 

 under stones in England and Wales. Another genus, Cryphoeca, 

 has three British representatives. 



(iii.) The HAHNIINAE are recognised at once by their spinnerets, 

 which are arranged in a single transverse line, the posterior pair 

 being on the outside, and generally much the longest. Hahnia 

 contains several species of very small spiders, of which four or 

 five are British, usually occurring among moss or herbage. The 

 aberrant form Nicodamus (Centropelmd}, usually placed among 

 the Theridiidae, is removed by Simon to the Agelenidae, forming 

 by itself the sub-family (iv.) NICODAMINAE. 



Fam. 31. Pisauridae. The Pisauridae are hairy, long-legged 

 spiders, intermediate, both in structure and in habits, between the 

 Agelenidae and the Lycosidae. Many new genera have recently 

 been added to the group, but many of them only include one or 

 two species. 



Pisaura is spread throughout the temperate regions of the 

 Old World, and P. (Ocyale) mirabilis is common in England, 

 being found abundantly in woods and on commons. It is a 

 striking spider, more than half an inch in length, and its elongate 

 abdomen is marked on either side with a sinuous longitudinal 

 white band. 



There are some thirty species of Dolomedes scattered over the 

 temperate regions of the world. D.fiiribriatus is a rare species in 

 marshy spots in the south of England, and is one of the largest 

 British spiders. The ground-colour is deep brown, with two 

 longitudinal yellowish stripes both on cephalo thorax and abdomen. 



The genus Dolomedes is replaced by Thaumasia in South 

 America.
