A single specimen of this fine species was amongst the fine 

 captures of Mr. Tillyard, in November, 1911. It differs from the 

 well-known aS' ylabricollis Newm., by darker colour, gi'eater size 

 (especially width), the sharply dentate anterior angles of pi'o- 

 thorax, nitid and glabrous abdomen, iiiter alia multa. It is still 

 further removed from the West Australian species, aS'. pilosicollis 

 Hope. Type in author's coll.
