RECORDS OF THE ATSTRALIAX MUSEim. 



a, -0111^ ATRACE^. 



Genus Hadronyche, L. Koch. 



Hadronyche cerberea, L. Koch. 



Two specimens of this species are included in the Museum 

 Collection, and are labelled Sydney, which is the type locality. 

 Both are females. There is no date or any other information 

 appended to them, but they have been in the collection to my 

 knowledge, more than twenty years. Both specimens agree 

 with Koch's general description, and one of them to the meas- 

 urements given bj' that authoi". The other, however, is consid- 

 erably larger, and I therefore a[)pend the following measure- 

 ments as a guide to students. They are, as usual, given in 

 millimeters : — 



9 Cephalothorax, 16.5 mm. long, 13.8 mm. broad ; abdomen, 

 18.3 mm. long, 14.6 mm. bi'nad. 



Falpi. — Trochanter and femur, 11 mm.; patella, and lil)ia, 

 7.1 mm. ; tarsus, 5.5 mm. ; total, 23.6 mm. 



Ohs. — Mr. H. R. Hogg, M.A., has described a form^- which 

 he thinks will, in all probability, prove tcj be a male oF tliis 

 species. His sj)ecimen came fi'oiu Macedon, N'irtoria. 



Geiuiii Atrax, (K F. Cmulir. 



Hogg gives the following svnopsisof the pi'eviously recoi'iied 

 species of this genus: A. nihiistiis, O. P. Cambr., and J. 

 modeittK, Simon, and to these I now add that of .1. rermda and 

 /A. f(u-)iii<h(Jiilis which 1 describe ludow : —
