ME. H. R. HOGG ON AUSTRALASIAN SPIDERS. [DeC. 2, 



light red fringes ; sternum red-brown, yellowish-brown hair. 

 Abdomen dingy yellow-brown above, brighter below ; three pairs 

 of dark spots on back, the anterior and posterior pairs being 

 round, and the median longitudinal lines as described by L. Koch 

 in his /. dolosa and /, villosa ; rather long downlying yeUow hair ; 

 on the underside only a slightly darker coloured narrow transverse 

 stripe behind the genital fold, and a faint shield-pattern. The 

 legs and palpi are bright reddish brown, with long upstanding 

 brown hair, the scopulse darker yellowish grey. 



The cephalotJiorax is rather flat, rounded at sides and broad in 

 front ; clypeus low, with a long and deep median sulcus, but only 

 faint side striae. 



The front row of eyes are equal in size, the median pair being 

 nearly two-thirds their diameter apart and nearly half as much 

 again from the laterals, the row being straight, they are their 

 diameter from the median of the rear row, which are two and a half 

 diameters apart (three-quarters of median) and three from their 

 laterals. 



There are no spines on the upperside of tibia iii. or iv. 



This is very like Isopeda villosa L, Koch, and the specimens 

 fi-om Central Australia (Horn Exp. pt. ii., Zool. p. 339) which I 

 took to be /. dolosa L. Koch. It differs from the former in the 

 front eyes being equal instead of laterals largest, and the side-eyes 

 farther from middle than the latter are from one another, and the 

 rear median nearer together than their distance from the side ; 

 the transverse stripe on the underside of the abdomen and the 

 sternum are not so dark. They also differ from the latter in 

 having the front row of eyes farther apart and not equidistant ; 

 legs longer in proportion, and cephalothorax not quite so flat.
