446 MR. H. R. HOGG ON AUSTRALASIAN SPIDERS. [DeC. 2, 



between cephalic and thoracic parts well marked, median sulcus 

 rather long. 



The front row of eyes is straight, the laterals are larger than 

 the median, which are half their diameter apart and the same or 

 rather less from the side; the clypeus barely one-third their 

 diameter ; the front and rear median are barely the diameter of 

 the latter apart, the diameter of the rear three-fourths of front ; 

 rear row straight ; middle eyes two diameters apart and slightly 

 more from the laterals. 



The teeth on the inner falx-sheath are three large and one very 

 small. 



One spine above on tibia iii., none on tibia iv. 



Measurements in millimetres. 



Long. Broad.

One female from Adelaide, sent to Brit. Mus. by Rev. T. S. 

 Lea. 



This species is rather close to I.frenchi, nov. sp., from Victoria, 

 and /. saundersi, nov. sp., from West Australia, both of which 

 have the same deep velvety-black sternum, the colour extending 

 partly over the coxse. It differs from both in a rather smaller 

 cephalothorax, in the eyes of both front and rear rows being 

 nearer together, the side-eyes larger than median of front row, 

 and closer together than in the former. 



IsoPEDA ARDROSSANA, nov, sp. (Text-fig. 95.) 



Female. — The cephalothorax is red-brown ; mandibles dark 

 red-brown with long pale yellow hair ; lip and maxillse dark brown ; 

 sternum black-brown with long thick hair extending over coxse. 

 The abdomen is dingy yellow-brown above, paler below, with a 

 transverse black band behind the epigyne. The legs and palpi 

 are bright orange with long silky hair, darker bands on tibife i., 

 ii., and iii., silver in between and under patella ; scopulse dark 

 grey. 



The cepludothorax is flatter than in /. ?eai, to which also it 

 is rather close, but the front-row eyes are equal and equidistant, 

 two-thirds of their diameter apart ; the medians rather more
