examples the spots and markings on this Spider may form a regular 

 pattern, perhaps very similar to that of Hecaerge spinimana. 



Two immature examples were found near Beirut, and another on 

 the plains of the Jordan. 



Hecaerge ? opiniosa, sp. nov. (Plate XVI. fig. 43.) 



Female adult, length 2f lines. 



The cephalothorax is of a short oval form, constricted laterally at 

 the caput ; its profile slopes gradually from the commencement of 

 the hind slope to the eyes. The normal grooves and indentations 

 are tolerably distinct ; and the hind slope is abrupt and broadly im- 

 pressed. The colour of the whole of the fore part of this Spider is 

 yellow. The eyes are on black spots, in two transverse very slightly 

 curved rows, near to each other, and the curves directed backwards. 

 The interval between the eyes of the central pair of each row is 

 greater than that between each and the lateral of the same row nearest 

 to it ; each central eye is, in fact, contiguous to the lateral next to it ; 

 the eyes of each lateral pair are close to each other, very nearly but 

 not quite contiguous. The leys are moderately long and not very 

 strong, their relative length 1,2, 3 (those of the fourth pair were 

 wanting) ; the tibiae and metatarsi of the first and second pairs have 

 a double longitudinal series of long sessile spines beneath them ; each 

 tarsus ends with two slender curved claws. The falces are mode- 

 rately long and strong, a little divergent near their extremities, and 

 their profile-line a little arched. Tbe maxillce are rather strong, 

 straight, but inclined to the labium, and a little enlarged on their 

 outer extremities. The labium is short and broad, rather narrower 

 and somewhat rounded at the apex. The sternum is short, heart- 

 shaped, and indented between the basal joints of the legs. The ab- 

 domen is of an elongate-oval form, and its colour is a dull whitish 

 drab-vellow, without any markings eitber above or beneath. The 

 genital aperture is narrow, chiefly marked by a transverse black- 

 brown line of the following form, — ■— '. 



A single example was found on the Lebanon. I have included 

 this Spider doubtfully in the genus Hecaerge. It appears to be 

 certainly a Drasside ; and its general appearance, as well as the 

 spines beneath the tibiae and metatarsi of the first two pairs of legs, 

 and the maxillae, seem to connect it with Hecaerge ; but the posi- 

 tion of the eyes is somewhat different, and indicates a nearer approach 

 to Drassus. 



Genus Agrceca (Koch). 



Agrosca lycosiformis, sp. nov. (Plate XVI. fig. 42.) 



Male adult, length 3f lines ; female adult, 4^ lines. 



The cephalothorax is oval, much broader behind than before, where 

 it is roundly truncated, and almost devoid of any lateral constric- 

 tion ; the profile line of the caput and thorax is almost uniformly 

 level; and the normal grooves and indentations are indicated by short 

 dark lines. It is of a dull yellow colour, clothed with paler hairs, 

 and has two broad longitudiual dark brown bands, one on either side
