are strongly suffused with black, as are also (though slightly) the 

 corresponding joints of the second pair. 



The whole Spider is of ordinary form and structure, and appears 

 to be allied to Melanophora electa and M. pumila (Koch). The 

 eyes are in two nearly parallel curved rows, the curves directed for- 

 wards ; those of the front row are very close to each other; the la- 

 terals, which are larger than the centrals (if not the largest of the 

 eight) are contiguous to them, while they (the centrals) are but 

 slightly removed from each other ; the interval between the eyes of 

 the hind central pair is greater than that between each of them and 

 the hind lateral on its side ; the eyes of each lateral pair are obliquely 

 placed and removed from each other by about one half of an eye's dia- 

 meter. The legs are short and strong, especially those of the first 

 pair, and the femora of all the legs ; they are tolerably thickly fur- 

 nished with hairs ; and there are a few longish spines on the tibiae 

 and metatarsi of the two hinder pairs. The maxillce are strong, 

 but of ordinary form, a little curved, and inclined to the labium, 

 which is oblong, and rounded at the apex. The falces are small, 

 moderately strong, straight, subcorneal, and nearly vertical. The ab- 

 domen is of an oblong-oval form and of a pale dusky brown colour, 

 with a strong tuft of black recurving bristles beneath the fore mar- 

 gin ; a largish marking of a long wedge-shape, and of a darker colour 

 than the rest of the abdomen, occupies the median line of the fore 

 half on the upperside ; and on either side of this is a longitudinal, 

 curved row of several small, pale reddish-brown, narrow, elongated 

 spots, the curves directed inwards ; the underside is of a pale whitish 

 yellow. The spinners are pale yellow, those of the inferior pair are 

 longer and stronger than those of the superior. The genital aperture 

 is small, apparently transverse, and divided longitudinally by a narrow, 

 arched, corneous kind of septum. 



Adult females of this species were found under stones near Jericho 

 and at Jerusalem.

This Spider is closely allied to D. lapidicolens (Walck.), which it 

 resembles both in general form, structure, and colour ; but it is much 

 smaller, and its caput is, perhaps, narrower ; the legs also are shorter 

 and stronger, and the palpi also shorter ; the radial joint is slightly 

 shorter than the cubital, and has a rather prominent but small sharp- 

 pointed red-brown spiny apophysis at its extremity on the outer side ; 

 the digital joint is small, but as long as the radial and cubital joints 

 together, and larger in proportion than that of D. lapidicolens ; the 

 palpal organs are small, consisting of a somewhat circular corneous 

 lobe, with a small black curved spine on its inner side, the sharp 

 point directed forwards, and a similar but shorter one on the inner 

 side, but more prominent ; the fine pale needle-like point of the latter 

 directed rather backwards and downwards ; the transverse impression 

 of the maxillae is stronger than in the species before mentioned, and 

 their extremities are not so ddated ; the eyes also of the hind central
