388 REV. O. P. CAMBRIDGE ON NEW DRASSIDES. [Julie 2, 



a number of specimens of various genera collected on the continent 

 of Europe in different localities, and given me by the late Mr. 

 Richard Beck, of 31 Cornhill, London. 



Drasstjs ornatus, sp. n. 



Immature female, length rather more than 2 lines. 



The only example met with of this species being immature, I should 

 not have ventured to describe it as new had it not been for the very 

 distinctive pattern upon the cephalothorax and abdomen ; that on 

 the abdomen especially will serve to distinguish it from every other 

 species known to me. 



In form and structure this Spider is of the common type of Drassus ; 

 the cephalothorax is reddish yellow, margined narrowly with black, 

 and with a broad longitudinal blackish-brown band on either side 

 touching the black margins. The rest of the fore part (except the 

 legs) is similar in colour to the cephalothorax. The legs are strong, 

 moderately long, yellow, and obscurely but broadly banded with dusky 

 brown, the genual, tibial, and metatarsal joints of the first pair being 

 wholly suffused with blackish brown ; they are furnished with hairs 

 and spines, the latter chiefly on those of the third and fourth pairs ; 

 the two terminal tarsal claws are slightly toothed ; they are not very 

 strong nor very strongly curved, and there is no claw-tuft beneath. 



The eyes are rather small, and placed in two very nearly parallel 

 transverse rows ; those of the hind central pair are oval, oblique, and 

 are separated by rather a wider interval than that which separates 

 each from the lateral of the same row on its side ; those of each lateral 

 pair are separated from each other by an interval equal to that which 

 divides the hind lateral and hind central eyes ; the four central eyes 

 form very nearly a square, the fore side being rather the shortest ; 

 the eyes of the front row are near together, being about equally 

 separated ; if any thing the interval between those of the central pair 

 of the front row, however, is rather greater than that which separates 

 each from the fore lateral nearest to it ; the fore laterals are the 

 largest of the eight ; the height of the clypeus is less than half that 

 of the facial space. 



The abdomen is of a broad oblong-oval form, tolerably convex 

 above, and projecting over the base of the cephalothorax ; it is of a 

 pale dull yellow colour, very sparingly clothed with hairs ; but 

 beneath the fore part is a transverse row of strong bristles curving 

 upwards ; this part is blackish brown, as also is a longitudinal central 

 narrow pointed band of the same colour on the fore half: from this 

 band issue at right angles three lateral blackish-brown stripes ; these 

 are continued obliquely over the sides, and are succeeded towards the 

 spinners by several others of a similar nature and parallel to those 

 on the fore part. The above-mentioned stripes are formed by small 

 blackish-brown spots and markings, and are very distinct and 

 characteristic, standing out strongly on the yellow ground-colour of 

 the abdomen. 



A single example was found under a piece of stone near Alexandria, 

 Egypt, by myself in April 1864.
