anterior angles widely obtuse and deflexed, posterior angles (seen 

 from above) rectangular, margins raised throughout, the lateral

 apieal declivity, intervals convex and impunctate; posternum 

 coarsely punctate, episterna with a few very large punctures, 

 metasternum with a few large punctures near base; abdomen

Dimension*. — IT x 5 mm. 



Habitat. — Otford, Gosford, Bulladelah (the author), Tambourine 

 Mountain (A. M. Lea and the author). 



A common species in New South Wales and South Queensland, 

 showing relationship To //. nitida, Blackb., and A. laticollis, Mail., 

 but distinguished from both by its impunctate pronotum. The 

 seriate punctures are larger, and elytral striae deeper and wider 

 than in //. nitida, though smaller and less pronounced than in //. 

 laticollis. 



Types in the author's coll. 



Nypsius, Champ. 



Xitid, metallic, flower haunting insects, with a short, wide pro- 

 thorax, deeply canaliculate, and sometimes deeply foveated, de- 

 scribed from Tasmania. Both species occur in Mr. Lea's tine coll. 

 There are also two specimens which cannot be distinguished from 

 N. foveatus, Champ., except that the foveae are wanting or sub- 

 obsolete. The species varies in size from G to <H mm. long. I have 

 taken A. aeneo-piceus, Champ., in the Australian Alps. Vie. (near 

 St. Bernard's Hospice). The two sp. may be thus distinguished : — 



1 Elytral intervals with a single row of widely separate punctures 



aeneo-piceus 3 Champ 



2 Elytral intervals thickly punctate foveatus, Champ
