described by the Rev. F. W. Hope in 1833, and none, I believej 

 have been added since. The present species is extremely close to 

 those of Mr. Hope but differs from them both, besides in some 

 other chai-acters less sti'iking, by the 3rd joint of the antennae 

 being nearly twice as long as the 2nd — those joints being stated by 

 Mr. Hope to be of the same length in his species. In M. affinis, 

 the colour is almost uniform, — a pale brownish-yellow, which 

 becomes a trifle moi'e decidedly yellow very narrowly along the 

 suture. 



I have seen a female example of this genus (also from Central 

 Australia) evidently belonging to another distinct species, but I 

 do not think well to describe it without having the male before me.

Macromalocera sinuaticollis, sp.nov. 



^. Elongata ; fusca, antennis pedibus et elytrorum sutura 

 lateribusque flavis ; breviter fulvo-pubescens; antennis corpori 

 longitudine requalibus, articulis 2° 3° que inter se tequalibus ; 

 prothorace quam ti'ans medium latiori baud longiori, ti'ans 

 basin quam trans medium multo minus tertia parte latiori, 

 confertim punctulato, valde insequali, lateribus sat late 

 reflexis (pone angulos anticos sat rotundatis, hinc retrorsum 

 externe concavis) ; elytris leviter punctulato-striatis, antice 

 utrinque vix lobato-productis. [Long. 8|^, lat. 2 lines.

This species differs from the description and figure of M. 

 ceramboides ^, Hope, in colour (that insect being uniformly 

 flavous except the scutellum which is black) and in the shape and 

 uneven svirface of the prothorax. From cvenosa, Hope (as redes- 

 cribed by M. Candeze, — Mr. Hope's description is merely of two 

 lines mentioning the colours) the insect before me differs in size 

 and in the shape of the prothorax, which in ccenosa is said to be
