Atrax modesta Simon. 



Atrax modesta E. Simon, Ann. Soc. Eut. France, vol. lx. 1891, 

 p. 302. 



Described by M. Simon from a female in tbe Paris Museum from 

 Melbourne. I have not seen it, but it is apparently smaller and 

 darker in colour. I have given (above, p. 272) the differences 

 deduced from M. Simon's description. 



Genus Hadronyche L. Koch. 



Hadronyche L. Koch, Die Arachn. Austr. 1873, p. 463 ; E. Simon, 

 Hist. JNat. d. Araign. i. 1892, p. 186. 



This genus differs from Atrax in having the pars cephalica of the 

 cephalothorax more raised up and rounder, but not so much so as 

 in Eriodon. The superior mammilla? are short and tapering ; the 

 first joint, divided at the back but not all round, is equal in length 

 to the remaining two, the second being slightly longer than the 

 third. The inferior mammillae are near together, cylindrical, and 

 truncate at end. The lip is square in front but not nearly so long 

 as broad, unless the whole distance from the sternum is included. 



Type, H. cerberea L. Koch. 



Hadkonyche cerberea L. Koch. (Text-fig. 40, p. 275.) 



Hadronyche cerberea L. Koch, loc. cit. 



Herr Koch's description is from two female specimens from 

 Sydney, for which he gives measurements : — Ceph. 11 mm. long; 

 abd. 14 ; legs (without coxas) 26, 24, 22, 27g mm. respectively. 



I have a fully developed male from Macedon, Victoria, a good 

 deal smaller, but in which 1 can distinguish no specific difference 

 from his description. Still of course the question is doubtful. 



Male. Cephalothorax chocolate-brown, with paler marginal edging. 

 Abdomen yellowish grey. 



Eront row of eyes straight and equal in size; middle their 

 diameter apart, half that distance from nearest point of side-eyes ; 

 rear side-eyes smaller than front and rear median rather close up 

 to them, smaller still. 



Lip broader than long, straight in front, round at sides and rear, 

 much be*pined. The maxilla? have a short rounded projection at
