186 BRITISH SPECIES OF PHALANGIDEA OR HARVEST MEN. 



The palpi have stronger spines or denticulse than those of P. 

 corniyer, the stronger ones more symmetrically arranged on the 

 humeral joints ; as well as some nearly as strong on the radial joints 

 at the inner extremity ; also on the humeral joints there are three 

 similar, but smaller, prominent spines directed inwards on a slight 

 protuberance. The apophysis at the inner extremity of the cubital 

 joint is longer in proportion than in P. corniger > being about frds 

 the length of the joint itself, while that in P. corniger is no more 

 than J. 



The armature on the cephalothorax is similar but less strong 

 than in that species ; and the legs are shorter, and are more or less 

 distinctly annulated with darker or lighter yellowish brown ; the 

 genital plate also is of a shorter more subtriangular form. Young 

 examples are much the most strongly and distinctly marked. 



There is but little, if any, difference in colours and marking 

 between the sexes. 



I first discovered this pretty little phalangid at Bloxworth in 

 1878, but the present is, I believe, its first record as a British 

 species. It is tolerably common at most seasons of the year, chiefly 

 at the end of winter and in spring, among grass and leaves, at the 

 roots of herbage and among moss in woods and on heaths in the 

 Bloxworth district. I have also received it from Ventnor in the 

 Isle of Wight, as well as from Ireland, co. Dublin, from G. H. 

 Carpenter, Esq. I have never met with it on low trees and under- 

 wood, situations in which P. corniger is frequently found. It is 

 rather sluggish and generally feeble in its motions. 



GEN : MEGABUNUS (Meade).

Cephalothorax armed with longish spines on the lateral margins, 

 and a single prominent one in the centre of the anterior margin of 

 the caput. 



Legs 2, 4, 3, 1 moderately long and armed with spines at the 

 extremities of the femoral and genual joints, and also with some 

 tubercles along the COXJB of the 1st pair.
