ting in two black sharp points, the lower one being the longest, 

 its apex extending beyond the organs (PL II. fig. I. 1, A). 



The epigyne of the female is short and conical, bearing at its 

 apex in front a small tongue-like upcurving process. It is more 

 prominent vieioed in profile than that of tenebricola, but when 

 viewed from above it so much resembles the same structure in 

 the next species that the difference cannot be described, except 

 that at all points that of zebrinus is rather more exaggerated 

 (fig. 1.2). 



This species, which is very likely to be confounded with 

 the next, although it will be seen on a close examination to 

 be very different from it, is of a bright orange-red colour, the 

 clypeus is higher than the ocular area, the anterior central 

 eyes are smaller and nearer together, the palpal organs form a 

 larger, more elongate mass, the lateral stylum is much more 

 conspicuous and longer, while the falciform process is larger 

 and terminates in a sharp spiniform point. 



The spiders are much more brightly coloured than tenebri- 

 cola. The females can be distinguished by the high clypeus 

 and the very small central anterior eyes, which are within half 

 a diameter from each other. The epigyne is more prominent 

 when vieioed in profile. 



Very abundant in the autumn amongst grass and other 

 herbage in woods, running actively in the warm sunshine. 



They are recorded from Dorset, Cumberland, Essex, Hert- 

 fordshire, Cambridgeshire, &c.

Length of male 1£ line. 



Cephalothorax dull brown, tinged with olive-green, the mar- 

 ginal line and striai tinged with darker brown. 



Legs pale straw-yellow, sometimes with an orange-red tinge. 



Abdomen very variable; markings consist of a central 

 dorsal series of transverse, dark black, V-shaped bars, their 

 free ends being dilated into a small blotch. The anterior 

 shoidders of the abdomen exhibit a short white slash of creta- 

 ceous spots, ojten in the male sex being the only pale markings 

 on the abdomen, the rest black. Often the pale dull-white 

 q round-colour is predominant, and the apices of the V-shaped 

 bars becoming obsolete, the dorsal pattern resolves itself into two 

 longitudinal series of dark spots, these often obsolete except just
