PULMONAltliE. 195 



The species of this genus are those more particularly designated 

 by the name of Crab-Spiders. The males frequently differ greatly 

 from the females in colour and are much smaller. 



Some of them, all exotic(l), have their eyes arranged four by four 

 on two transverse and almost parallel lines, the posterior of which 

 is the longest. 



In the others, and the greater number, the ensemble of these eyes 

 represents a crescent, the convex side of which is forwards and out- 

 wards. 



Thomisus globosus; Jlranea globosa, Fab. ; Jlranea irregularis, 

 Panz., Faun. Insect. Germ, fascic. LXXIV, tab. xx, female; 

 Walck., Faun. Franc, Aran., VI, 4. Three lines long; black; 

 abdomen globular; red or yellowish all round the back. 



Thomisus crisfatus; Clerck, Aran. Suec, pi. 6, tab. vi, size 

 of the preceding; body grey-reddish, sometimes brown, with 

 scattered hairs; feet with small spines; lateral eyes largest 

 and placed on a tubercle; a transverse yellowish stripe on the 

 front of the thorax; two others of the same colour on the back 

 forming a V; abdomen rounded, and a yellowish band on the 

 middle of the back with three indentations on each side. A 

 common species frequently observed on the ground. 



Thomisus citreus', Jlranea citrea, De Geer; Schaeff. Icon. In- 

 sect., tab. xix, 13. A lemon yellow, with a large abdomen 

 wider- behind; two red or saffron coloured streaks or spots are 

 frequently observed on the back. On flowers(2). 

 A subgenus established by M. Walckenaer, under the name of 

 STORENA,but which is yet but imperfectly known, should apparently 

 terminate this section and lead to Oxyopes, which are as nearly allied 

 to the Crab-Spiders as to the Citigradse. The Storenae have their 

 jaws inclined on the ligula, which is nearly of the same length, and 

 forms an elongated triangle; the chelicerse are conical; the two ante- 

 rior legs, and then the second, longest; the two following ones longer 

 than the last. The eyes are arranged in three transverse lines, 2, 

 4, 2; the posterior, with the two intermediate ones of the second lines, 

 form a small square, and the two anterior ones are distant(3). 



Other Aranese whose eyes, always eight in number, extend more.
