117. Size 20-23 mm. long, pronotal spot not invading disc, 



, elytra with postmedial fascia bile-bed and subapical 



triangular spot extended to apex — praecellens, Kerr. ; 

 fi<nch I, Blackb. (var., without yellow spot on pro- 

 thorax, ground-colour of elytra red). 



Note. — A specimen of this beautiful and rare 

 species was taken by me at Wangaratta, Victoria. 

 Mr. W. Duboulay tells me that his father took it at 

 Albury. A specimen sent me from Inverell, corre- 

 sponding with two in the Macleay Museum (from 

 Murrurundie, New South Wales, and Ipswich.. 

 Queensland, respectively), is very similar in structure* 

 and pattern, but has a darker elytra and is without 

 any yellow on the border or underside of prothorax. 

 At present I hesitate to call this other than a variety 

 of praecellens.
