relative length 1.4.2.3. Palpi short ; radial j oint smaller than tlio 

 cubital, with a bluntish apophysis at its extremity on the upper 

 side ; digital joint large, oval ; palpal organs very prominent, 

 with a projecting process at thoir base, from the outer side of 

 which issues a black spine curving across the middle to tho 

 inner side. 



Abdomen small, oviform ; very deep brown, approaching to 

 black ; clothod with hairs, of which some are of a pale whitish 

 colour. 



Found among rubbish in an old hedgerow on Hursley Down, 

 near Winchester, in May, 1860, and closely allied to Lethia 

 allispiracuMs, Cambr. (p. 53), but among other distinctions its 

 cephalo-thorax is broader in proportion to its length, than in 

 that species. In the original description of this spider (Ann. 

 and Mag. N.H., 1861) the legs are stated to be " furnished with 

 a few spines." I think this is a mistake, at any rate I cannot 

 now discern traces of spines, though the specimen has been sub- 

 jected to rather rough usage since that description was made. 



LETHIA SPINIGERA, Sp. n. 



Adult male, length l-14th of an inch. 



The cephalo-thorax is oval, broadly truncated behind, and 

 moderately convex above ; the profile line to the hinder slope is 

 even, and forms only a slight curve, the hinder slope tolerably 

 abrupt, and the lateral marginal constrictions at the caput are 

 very slight. Its colour is a dark yellowish-brown, with deeper 

 converging lines, and a few prominent bristly hairs in the medial 

 line. The height of the clypeus (which is very low) appears to 

 be rather less than half that of the facial space. 



The eyes are small, subequal, and closely grouped together, 

 in two parallel, transverse, contiguous lines. Tho interval 

 between those of the hind-contral pair, which are smaller than 

 the hind-laterals and of a somewhat misshapen form, is equal to 

 rather more than a diameter, and each is contiguous to the hind-
