128 ON TWO NEW SPECIES OF AUSTRALIAN CETONIID^, 



the head. Thorax slightly rounded at the sides, the base tri- 

 sinuoiis with the lateral angles obtuse and slightly prominent, 

 very finely and sparsely punctured on the disk, coarsely punctured 

 at the sides. Scutellum smooth, the apex produced and acute, the 

 sides impressed. Elytra impressed in the region of the scutellum, 

 sparsely punctured near the suture, the sides with very coarse 

 confluent transverse strise. Pygidium concentrically strigose. 

 Underside closely punctured and with long grey pubescence at the 

 sides ; mesothoracic epimera smooth on the upperside ; meta- 

 sternum longitudinally impressed in the centre, the mesosternal 

 process broad and rounded at the apex; abdomen slightly impressed 

 in the centre, apical margin of the penultimate segment punctured 

 and fringed with long grey hairs. Legs punctured and pubescent, 

 anterior tibise with a small lateral tooth about one-third from the 

 apex. Length 24 mm. 



Warra, New South Wales (Capt. W. Peel). 



Apart from the great difference in coloration this species is 

 extremely like D. dorsalis, Don.; the punctuation however is 

 altogether more sparse, the base of the thorax is more broadly and 

 less deeply emarginate before the scutellum. the sutural interstice 

 of the elytra is narrower towards the base, and there is a small 

 but distinct lateral tooth on the anterior tibiae. 



I am indebted to my friend Mr. A. Sidney Olliff for a male 

 specimen of this fine species. The female is unknown to me."^ 



* In communicating Mr. Janson's Paper to the Society I venture to add 

 the characters of the female of this species, of which sex a single and 

 greatly damaged example is in the collection of the Australian Museum. 

 It is 28 mm. in length, and has the markings disposed as described above, 

 although they would appear to be more widely separated, and therefore 

 more conspicuous ; the punctuation on the prothorax is coarser ; the sides 

 of the elytra are only sparingly provided with transverse stria? ; and the 

 basal joint of the antennae is red dish -yellow. In the male the elytral 

 markings occasionally coalesce, and judging from the half-dozen specimens 

 I have seen, display considerable variation in form and size. — A. Sidney 

 Olliff.
