of the under side. The form of the abdomen of the female 

 is suh-globular, that of the male being oval ; and the legs are 

 long, very slendor, and like tho cephalo-thorax in colour. Thoro 

 is much variation in the markings of the upper side of tho 

 abdomen ; in some females it is of an almost uniform whitish 

 hue, with a f ow indistinct, veiny, dusk/ linos ; some are as first 

 above described; others, both malo and female, have two longi- 

 tudinal, bright carmine bands which unite at each extremity ; 

 and in others, almost tho whole of the upper side is carmine ; 

 but in all cases the horso-shoe ring of black and white spots 

 and the sub-abdominal black band are present. The sternum 

 is yellow, with a black marginal, and longitudinal central lines. 



The snare of this spider consists of numerous lines crossing 

 and re-crossing each other among the small branches and leaves ; 

 the egg cocoon is secured by silken lines under tho leaves, of 

 which sevoral are usually drawn together, and form a kind of 

 tent for tho protection of tho oggs and young ; tho latter living 

 beneath its shelter for some time after they are hatchod. 



It appears to be equally abundant throughout Great Britain, 

 and, indeed, Europe generally.

Length of the male l-12th of an inch; of tho female l-10th 

 Very much smaller than tho last species, though bearing some 

 gonoral resemblance to it in colours and form. It may be dis- 

 tinguished among other characters by throe, broken, black lines 

 and markings on the abdomen, in lieu of the distinct black 

 spots in Phjllonetlm lineata ; as woll as by tho absence, in most 

 casos, of tho ring of spots round tho spinners ; in somo examples 

 thoy are indistinctly apparent. Tho cephalo-thorax and sternum 

 are immaculate, oxcopting a broadish, central, longitudinal, 

 tapering, dark band on the former. Tho males have long and 

 divorgont falces very like thoso of Phijllonelhis lineata, but some-
