re-described some of them, as their description is in no case very 

 full or detailed. 



The known Amarygmi are much less numerous than the Chal- 

 copteri and the species are much rarer in collections. It is 

 noteworthy that I have seen only a single species from Western 

 Australia or Tasmania, and only three species from South Aus- 

 tralia and Victoria, two of which are represented by unique types. 

 A. Prothorax not strigose. 

 B. Elytral sculpture distinctly longitu- 

 dinal, 

 C. Elytral sculpture consisting of punc- 

 tulate striae or rows of punctures. 

 D. Prothorax or interstices of elytra, 

 or both, distinctly punctulate. 

 E. Form more or less elongate. 

 F. Tibiae of dark colour. 

 G. Elytra uniformly black or 

 aeneous, very uitid, and 

 strongly striate. 



H. Size 5 lines or more. 



I. The punctures in the elytral 



striae very uneven in size 



and distance apart uniformis, Blackb. 



II. The punctures in the elytral 



striae very even, a little 



hner hind ward alienus, Blackb. 



HH. Size 4 lines or less [semissus, 'P&bq,] 



GG. Elytra not as in G. 

 H. Head between the eyes more 

 or less nitid and very dis- 

 tinctly punctulate. 

 I. Sides of head extremely feebly 

 reflexed above the base of 

 the antennae.
