the rest of the fore part) of a pale orange-yellow colour, and differs 

 hut little in size. 



The eyes are large, and are placed, as usual, in two transverse 

 curved rows, of which the foremost one is slightly the longest, and 

 the hinder one the most curved, the area they describe being no 

 more than one third longer in its transverse than in its longitudinal 

 diameter : the hind centrals are oval, oblique, of a pearl-grey colour 

 and margined with black ; they are very near together and not 

 quite contiguous; and the interval that separates them is about 

 equal to that which divides each from the hind lateral nearest to it, 

 being no more than one fourth of a hind central eye's diameter : 

 each hind lateral is separated by half its diameter from the fore 

 lateral next to it, and is contiguous to the fore central eye on its side. 

 The fore centrals are unusually large for these eyes, being as large 

 or larger than the fore laterals ; they are round, dark-coloured, 

 separated from each other by rather less than half a diameter, and 

 (like the same eyes in many others of the genus) placed on some- 

 what of a slight eminence: the four lateral eyes are margined with 

 black, and of a pearl-grey colour, but not quite so dark as the hind 

 laterals. 



The J alces are small and almost vertical. 



The legs are shortish ; relative length 4, 1,2, 3, moderately 

 strong, furnished sparingly with hairs, and with a few short weak 

 spines on the tibiae and metatarsi of the two hinder pairs ; there are 

 also one or two longer and stronger ones on the fore sides of the 

 femora of the same pairs. 



The maxillcB are normal in size and form ; but the palpi issue 

 from the middle point of their length. 



The labium also is normal. 



The abdomen is oblong-oval, truncated before ; it is sparingly 

 clothed with hairs, and is of a pale dull luteous yellow colour ; it 

 projects but very slightly over the base of the cephalothorax, and at 

 that part has some strong upturned bristles : four impressed dusky 

 spots form a largish quadrangular figure on the fore half of the upper 

 side ; this figure is longer than broad, and its fore side is slightly 

 shorter than the hinder one : a narrow, somewhat tapering, indistinct 

 dusky marking is defined by two nearly parallel dusky lines along 

 the middle of the fore half, running between the two foremost of the 

 above-mentioned spots. The spinners of the inferior pair are not 

 as long as in many other species, but much longer than those of the 

 superior pair. The form of the genital aperture is simple, but 

 peculiar {vide Plate LI. fig. 9). 



A single adult female was found by myself under a stone near 

 Alexandria, in April 1864. 



Prosthesima cingara, sp. n. (Plate LI. fig. 10.) 



Adult female, length not quite 3 lines. 



In general form and structure this species presents nothing 

 peculiar, and in its dark and sombre colouring it much resembles P. 

 ■pedestris (Koch) and P. tristicula (Cambr.) ; the form of the
