THE SPIDERS OF EPPING FOREST. 



By FRANK P. SMITH. 

 [Cotttimied from p<ige 6o). 

 {With Plates IX. and X.) 



Family ANYPHAENIDAE. 



[Drassidae, Cambr. List, ad partem.'] 

 This family is very closely allied to the Clubionidae, but the single genus 

 represented in Britain may be easily distinguished from that family by the tube- 

 tracheal opening being placed not immediately in front of the spinners, but in a 

 conspicuous transverse depression about half-way between the genital aperture 

 and the posterior extremity of the abdomen. 



Gemis ANYPHAP:NA, Sund. 

 Spiders of moderate size, usually with distinct blackish 

 markings upon the pale abdomen. The males are often much 

 more darkly coloured than the females. A single species occurs 

 in Britain. 



Anyphaena accentuata, Walck. Commonly beaten from 

 trees in many parts of the forest. 



Family SPARASSTDAE. 

 Cephalo-thor ax longer than broad, strongly constricted at the caput. Eyes 

 8, almost homogeneous (of the diurnal type), rather small, not greatly unequal in 

 size, anterior row recurved, posterior row unusually procurved. Clypeus narrow. 

 Ldbiu7n short, almost semicircular. Maxillae rather straight, never much inclined 

 towards the labium. Legs^ second pair shorter than fourth pair. Spines present 

 and fairly strong. Claw tuft and scopula present. Tarsal claws, 2. 



The Sparassidae are spiders intermediate in characteristics 

 between the Clubionidae and the Philodromidae. They 

 spin no snare. One genus is found, but rarely, in Britain. 



Gejitis SPARASSUS, Walck. 

 [Micrommata, Cambr, List.] 



Spiders of rather large size and brilliant colours which have 



many structural affinities with the Clubionidae, but in their habits 



remind one more strongly of the Philodromidae. One rare and 



beautiful species, 5. vivescens, Clk, has occurred in Britain, but 



not in Epping Forest. 



Family PHILODROMIDAE. 

 [Thomisidae, Cambr, List, ad partem Philodrominae.] 

 Cephalo-thorax short and broad, strongly constricted in the region of the 

 caput, and obtuse and rounded in front. Eyes eight, of the diurnal type, not 

 greatly unequal in size, arranged in two recurved rows, the whole group describing 

 a figure of a more or less crescent-like form. Legs ; relative length varies in 

 different species. Those of the first and second pairs are always somewhat
