662 Mr. BrackwaLv's Descriptions of new Species of Spiders. 
The male is smaller and slenderer than the female, but the relative 
length of his legs is the same; their absolute length, however, is greater, 
an anterior one measuring 45ths of an inch. He resembles the female in 
design, but is darker coloured. The cephalo-thorax, mandibles, maxille, 
lip, and sternum, have a tinge of red, and the legs are without the green 
tint perceptible on those of the other sex. Fourth joint of the palpi 
much stronger than the third, a long, slender bristle projecting from 
each, near the extremity, in front; fifth joint oval, very dark brown, 
convex and hairy externally, concave within, comprising the palpal or- 
gans, which are prominent, highly developed, complicated in structure, 
with a pointed, corneous spine, directed from the inner side obliquely 
downwards, and a delicate, prominent membrane at the extremity ; their 
colour is very dark reddish brown. 
In May and June Linyphia rubea spins a web of moderate extent in bushes, 
and is of frequent occurrence in the woods of Denbighshire and Caernarvon- 
shire. It has been captured by Miss Ellen Clayton in the north of Lancashire, 
and by T. Glover, Esq. in the neighbourhood of Manchester.
