LETHIA PUTA. 



Ciniflo ptjta, Cambr., Zoologist 1863, p. 8570, ami Trans. Linn. 

 Soc. xxviii, p. 440. 



The length of the female of this minute species is one-fifteenth 

 of an inch, being thus much smaller than either of the fore- 

 going, from which it may readily bo distinguished by its almost 

 uniform yellow-brown colour ; faint traces, however, of a pattern 

 on the abdomen somewhat similar to that of L. Mengii may bo 

 seen on a closo examination. 



A single example only has yet been recorded in England, and 

 this was found by myself at Bloxworth in 1861. It has been 

 found in Prussia, and I have also receivod it from France. 



LETHIA ALBISPIRACULIS. 



Lethia albispiraoulis, Cambr., Ann. and Mag. N. H., S. 5, vol. 

 1, p. 109, p. xi., fig. 1. 



This spider is very nearly allied to Lethia puta, but is rather 

 larger, stouter, and darker coloured ; it is also easily distinguished 

 by the shining white, spiracular plates, beneath the fore 

 extremity of tho abdomen. The pattern on the abdomen is 

 'somewhat similar to that of L. puts, but the vertices of the pale 

 angular lines on the hinder half of the upper side, as well as 

 their extremitios, are, each, marked with a minute tuft of white 

 hairs, thus forming three longitudinal and nearly parallel lines 

 of tufts. 



The longth is about one-thirteenth of an inch. 



Threo adult females were found under stones on tho Weymouth 

 shore of the Chesil Beach, Portland, on the occasion of the first 

 meeting of the Dorset Natural History Society and Antiquarian 

 Field Club, June 1st, 1875.
