294 NOTES ON AUSTRALIAN COLEOPTERA, 



Maris (1) an tennis prothoracis basin articulo apicali superanti- 

 bus ; )>rothorace quam trans angulos posticos latiori vix 

 longiori. [Long. 7, lat. 2 lines. 



This species is isolated frorti most of its Australian congeners 

 by the very narrow lamellae of its tarsi. The structure of the 

 lateral margins of its prothorax is also unusual. These margins 

 instead of being continuously lateral (as they are in M. Austra- 

 lasice) are deflexed near the front and pass on to the prosternum, 

 but without forming a prosternal gutter (as they do in M. carinatus, 

 &c.) ; nor are the lateral portions of the prosternum f which are 

 very closely punctulate-strigose) explanate, having only the very 

 slight narrow flattening which is seen in AI. Australasice and 

 numerous other species. These characters, together with the 

 extreme brevity of the inner carina of the hind angles of the 

 prothorax, the decidedly convex elytral interstices, and the distinct 

 (though not very conspicuous) reddish spot on either side of the 

 scutellum will render the species easy to identify. To a casual 

 glance it looks much like M. Australasice, though not in reality 

 closely allied to it.
