THE SPIDERS OF EPPING FOREST. 213 



of this Species, were found amongst heather near the " Robin 

 Hood." 



Oxyptila atomaria, Panz. A single female, taken some- 

 where in the Forest a few years ago, is my only record, but unfor- 

 tunately the locality was not noted at the time of capture. 



The British species not yet found in the Forest are O. tyiiXy 

 Bl. ; O. flexa, Cambr. ; O. sanduavia, Cambr. ; and O. hlackwallii, 

 Simon. 



Gemis DIAEA, Thordl, 



Crab-Spiders of moderate size and of brilliant colours, green 

 being a prevailing tint. The sexes are exceedingly dissimilar. 



Diaea dorsata, Fabr. The female of this beautiful green 

 spider has been taken on several occasions at Loughton and 

 Theydon Bois. 



Two other species are recorded as British, D. fovmosa,^\.\ 

 and D. devoniensis, Cambr. 



Genus ^MISUMENA, Simon. 



Large spiders of uniform pale tints. One species occurs in 

 Britain, and is not uncommon in the Forest. 



Misumena vatia, Clerck. Found hiding amongst the 

 blooms of various plants, where it lies in wait for unsuspecting 

 insects who visit the flowers in search of honey. 



Genus PISTIUS, Simon. 



A single species of this genus, P. tvuncatns^ Pallas, is found in 

 Britain, but it has not occurred in the Forest. 



Gams THOMISUS, Walck. 

 In this genus the caput is peculiarly angular, and the 

 abdomen abruptly truncated at its posterior extremity. A single 

 species occurs in Britain. 



Thomisus onustus, Walck. An immature male amongst 

 heather near the *' Robin Hood" is, at present, the only record 

 for the Forest. 



Family SALTICIDAE. 



Cephalo-thorax large compared with the abdomen, very wide in front, its 

 sides being often nearly parallel. Eyes, eight , of the diurnal type. Four 

 large eyes form a transverse row upon the front of the caput, the remainder 

 being small, and arranged in a quadrate figure upon the upper surface of the 

 cephalo-thorax, Falces usually normal, but in some cases peculiarly exaggerated 

 in the male sex. Sternum narrow. Palpi normal, that of the male being 

 furnished with an apoph}sis upon the tibia, and occasionally upon the femur
