310 REV. O. P. CAMBRIDGE ON THE [Feb. 20, 



Adults of both sexes, as well as immature females, were found 

 generally distributed throughout Palestine and Syria. The name 

 conferred upon it is that of Dr. T. Thorell, Adj. Prof. Zool. Univ. 

 Upsalse, Sweden, a most able and hard-working araneologist.

Adult males of this species were found on the plains of the Jordan 

 and also near Damascus. 



Walckenaer has confused both this and the next species with 

 Araneus formicinus (Clerck), from which they are perfectly distinct ; 

 both were found by myself in Egypt in 1864.

An adult male, with females both adult and immature, were found 

 running on the ground at Jerusalem and near Jericho.

Female adult, length 2{ lines. 



This Spider is very nearly allied to P. thorellii, but may be di- 

 stinguished by the form of the characteristic central longitudinal 

 lanceolate marking on the upperside of the abdomen : in that species 

 this marking is acutely pointed behind ; but in the present it is cut 

 off transversely in a straight line, with a small projecting point at 

 each corner of its extremity ; the abdomen is also thinly but con- 

 spicuously furnished with short, strong, erect,.semidiaphanous bristles 

 or fine spines ; the cephalothorax is yellow, with a broad deep-brown 

 longitudinal band on either side, leaving arcentral and two marginal 

 yellow bands, of which the central is the broadest, and has a long 

 wedge-shaped marking faintly defined by brownish lines, which reach 

 from the eyes nearly to the hind margin of the cephalothorax. The 

 legs are moderately long, their relative length 4, 2, 3, 1 ; they are 

 furnished with hairs and a few very fine spines, and are yellow in 

 colour, with a faint brown marking and clouding here and there. 

 The abdomen is oviform, and, as above remarked, is armed on its 

 upperside with short strong pale bristles or fine spines ; it is of a 

 deepish yellow-brown colour above ; and the fore half has along its 

 middle a conspicuous oblong deep-brown marking, with a slightly 

 angular point on either side about the middle, which is its broadest 

 part ; its hinder extremity is truncate, with a small point at each 

 corner ; this marking has its fore half defined by a yellowish mar- 

 ginal line ; the hinder part of the upperside has several short oblique 

 lateral yellowish bars, which run into the uniform yellow ground- 

 colour of the sides ; the sides have also a broad longitudinal patch 

 or irregular band of black, on which one or two oblique yellowish 

 bars are observable. The underside of the whole Spider is of a dull 

 pale yellow colour. A single example of the adult female was found 

 on the road leading from Nazareth to Mount Carmel.
