with the figure, and its identity does not seem open to ques- 

 tion. The prothorax on Chapuis' co-type, and on several 

 other specimens in the Museum, has each side obtusely sub- 

 angulate in two places about the middle, but on. many speci- 

 mens they are quite evenly rounded. The colour, whilst 

 usually bronzy or brassy, also varies considerably, many 

 specimens being blue, or deep bluish-green witli purple 

 reflections, or entirely purple, except that the legs and 

 antennae are m.ore or less reddish (occasionally, however, 

 the femora are more or less dark, sometimes with a metallic 

 gloss). The species is common in many parts of South 

 Australia, Victoria, and Tasmania, and specimens from the 

 latter State were named Xoda tasmanica by Jacoby ; there 

 are also two specimens in the Macleay Museum labelled as 

 from Port Denison, in Queensland. 



Agetinus aequalis, Blackb. 

 PL viii., figs. 127 and 128. 



The type, and a co-type, of this species are in the 

 Museum. The legs are stout; the tibiae longitudinally 

 canaliculate and dilated to the apex, each of the frcnt ones 

 has a conspicuous subtriangular notch near the apex due to a 

 portion of the apex being scooped out for the reception of 

 the base of the tarsus, so that when viewed from below the 

 apex appears to be terminated by a thin flange. The notch 

 is invisible from directly above, but from behind it is very 

 conspicuous; it is bounded posteriorly by a triangular tooth. 

 In general appearance the species is very unlike the typical 

 one fsuJ)aequaUs), but as the front tibiae are much as on 

 vifidirirr/nfus, it may be as well to leave it in Ar/etinus. In 

 addition to the specimens mentioned there are numerous 

 others identified as aeqiiaJis by the late Rev. T. Blackburn ; 

 but these differ in being smaller and green, or brassy-green, 

 or blue, or purple. They all have the elytra strongly ccnvex 

 along the middle, and from the suture to the margin each has a 

 curious sloping (almost obliquely flattened) appearance, so 

 that a section acrcss the middle would be almost triangular. 

 The elytral costae are so extremely feeble that it would be 

 better to regard them as absent. The male differs from, the 

 female in having the abdomen slightly less convex, more 

 depressed at the sides and the apical segment with a small 

 fovea ; the front tarsi (more especially the basal joint) are 

 also wider. 



There are also in the Museum four males from Darwin 

 (G. F. Hill's No. 65) that perhaps represent a variety. They 

 are brassy like the type, but considerably smaller, and the
