rounded apices to the elytra. The sides of the thorax are 

 rounded in front ; the posterior angles are rather less than right 

 angles. The elytra are deep ^teel-blue, strongly punctate- 

 striate ; the interstices are scarcely convex, very finely and 

 not thickly punctured ; but there are some large punctures 

 about the shoulders. Each elytron has two bright red spots ; 

 the larger one occupies all the base except the scutellar region ; 

 the second spot is near the apex, commencing on the margin, 

 and, extending obliquely upwards, nearly reaches the suture. 

 Hah. New South Wales. Brit. Mus. 



This species differs considerably from all the other Stigmo- 

 derce.j but should, I think, be placed next to S. hifasciata^ 

 Saund., which it most nearly resembles in form. 



Fam. MelolontMdse. 

 Calonota, Hope. 



I have examined many examples of Calonota, and am un- 

 able to detect more than eight joints to the antennas (not nine, 

 as given by Lacordaire), The third joint is very long, cylin- 

 drical; the fourth the same form, but shorter; the fifth very 

 short, thickened at the internal apical angle ; the sixth, seventh, 

 and eighth form the club, elongate in the male, ovate in the 

 female. 



The name Pyronota, Boisd., although prior to that of Hope, 

 is given without any proper characters for the genus ; and I 

 therefore adopt Hope's name. 



I am unable to distinguish more than one species of this 

 genus. I am even unable to find any definite characters to 

 separate the piceous form, with pale margins and broad tliorax 

 (which at first appeared quite distinct), from the typical bright 

 green C.festiva. I find intermediates both in form and colour. 



PiiYLLOCOCERUs, Hope, MS. 



Antennae nine-jointed ; first joint much enlarged at the apex ; 

 second nearly globular ; third, fourth, and fifth cylindrical, 

 subequal, a little shorter than the second ; sixth joint very 

 short, but broader than the previous joint ; the seventh, eighth, 

 and ninth joints forming a club, very long in the male, elon- 

 gate-ovate in the female. Clypeus somewhat deeply triangu- 

 larly emarginate in the middle. Mesosternal projection long, 

 conical. Posterior coxfe with the internal angle not produced 

 into a spine ; posterior femora with a small triangular pro- 

 jection on the internal lower margin. Claws simple.
