clothed with coarse black and golden coppery hairs; along 

 the hinder half of the upper side may often bo traced a series 

 of angular lines (generally defective in the middle or angular 

 part) formed by coppery-red hairs. In some examples these 

 lines appear to be connected by other short lines, forming two 

 longitudinal, parallel, dentated lines along the middle. 



The female is not quite so dark colourod as the male ; her 

 legs are more distinctly annulatcd, and the palpi are of a clear, 

 pale, yellow hue ; the anterior eyes and clypeus also are wanting 

 in the scarlet irides and hairs, and the angular lines on the 

 abdomen are more distinct than in the male. 



This pretty little spider is allied to Euophrys oequipes, but may 

 be easily distinguished by its darker colours, and (in the males) 

 by the striking contrast of the scarlet irides, and similarly 

 coloured hairs on the clypeus, with the white hairs on the dark 

 coloured palpi. 



Euophrys petrensis is not unf requent in May and June on the 

 barer spots of dry sandy and gravelly heath at Bloxworth, 

 where the heather is scanty, but has not yet been found in any 

 other locality in Great Britain. Its activity is very great, and, 

 like many others of its family, it loves sunshine, becoming at once 

 dull and sluggish on the obscuration of the sun's rays. It 

 appears to prey (among, no doubt, other insects) upon ants and 

 podurso, both of which aro common where this spider occurs. 

 The female produces only a very few eggs, which sho encloses, 

 along with horself, in a little white silken nest beneath a stone.

The spiders of this group may be distinguished from Euophrys 

 by the more elevated cephalo-thorax, and the greater proportion- 

 ate length of the legs of the fourth pair. The thorax is from a 

 quarter to a half longer than the caput, and the ocular area is 

 scarcely a quarter more in breadth than in length, but is rather
