Length of the male, ^ths of an inch; length of the cephalo-thorax, Mbs, breadth, tth; 
breadth of the abdomen, |th; length of an anterior leg, l 
The legs are provided with short hairs, and have a yellowish-red hue; the first pair is 
rather the longest, then the second, and the third pair is the shortest; each tarsus is termi¬ 
nated by two curved, pectinated claws, below which there is a small scopula. The palpi 
resemble the legs in colour; the digital joint is slightly dilated, and the palpal organs, 
connected with it by a short pedicle near the middle of the under side, project from it almost 
at right angles; they are somewhat pyriform, and terminate in a slightly curved, obtuse 
process, having a protuberance on its outer side, and are of a pale-reddish colour. The 
cephalo-thorax is oval and moderately convex, with a slight indentation in the medial line ; 
the falces are long, prominent, conical, and fringed with hairs on the inner surface; the 
maxillae are greatly enlarged where the palpi are inserted, pointed at the extremity, and 
supplied with hairs on the inner surface; the lip is hollowed at the apex, and has a transverse 
furrow at its base; and the sternum is oval. These parts are of a dark-red colour. The 
two anterior eyes, which are almost contiguous to the frontal margin of the cephalo-thorax, 
are the largest of the six. The abdomen is oviform, convex above, and projects a little over 
the base of the cephalo-thorax; it is sparingly clothed with short hairs, and has a yellowish- 
brown hue. 
An adult male of this species was comprised in a collection of British spiders received 
from Charles C. Babington, Esq., M.A., in 1840. M. Walckenaer is certainly mistaken in 
supposing that Dysdera rubicunda is merely a variety of Dysdera erythrina (‘ Hist. Nat. des 
Insect. Apt.,’ t. ii, p. 444), as well-marked differences in the structure of the palpal organs of 
the males prove to demonstration that they are distinct.
