,posed to consider it a colour var. with the elytral sculpture acci- 

 dentally wanting in distinctness were it not for the very evident 

 difference in the antennal structure, — the penultimate joint being 

 very much narrower than the antepenultimate and not much less 

 than half again as long as wide, while in the same sex of 

 hcsmorrhoidalis the penultimate joint is scarcely narrower than 

 the antepenultimate and is scarcely if at all longer than wide. 

 As Lycus atratus, Fab., is very insufficiently described and there 

 cannot be much doubt of this Tasmanian Metriorrhynchus being 

 identical with it I have thought it desirable to describe it fully.

Easily distinguishable from most of its congeners by the surface 

 of its pronotum being divided into five areolae, of which the two 

 antero - lateral ones are coarsely punctulate. Differs from 

 M. clientulus, Waterh., inter alia by the four principal elevated 

 lines on the disc of its elytra being equal inter se, and the hind 

 angles of its prothorax not produced outward.

The long slender rami into which the antennal joints of the 



male are produced distinguish this species from all the other 



described Australian members of the genus (except gigas, Blackb.) 



having similar colouring (entirely black except the entirely red 



elytra). From gigas it differs by its narrower and more elongate 



form, the distinctly testaceous tone of colour on the elytra, the 



tendency of the elytral costse to become feebler towards the apex, 



the narrower prothorax (especially in proportion to the width of
