of the anterior margin. Elytra irregularly and strongly punc- 

 tate-striate near the suture, slightly dejiressed below the base, 

 the interstices at the sides transversely rugose and longitudi- 

 nally tuberculate, the apex with some regular and distinct co- 

 stae. Legs dark fulvous, the posterior femora with an obscure 

 aeneous spot near the apex; first posterior tarsal joint double 

 as long as the second. 



Austraha, Somerset (Cape York) (L. M. D'Albertis). 



The female of this species is much larger, and the entire 

 surface of the elytra is more or less strongly tuberculate, at 

 the sides the tubercles are very large and arranged in longi- 

 tudinal rows. 



It is impossible to refer this species of which more than ten 

 specimens are before me, to any described form on account of 

 the entirely fulvous legs and tarsi and the differently sculptui-ed 

 thorax and elytra. 



Thyi'tisia, n. gen. {Eumolpldae Sect. Typophorinae). 



Body elongate. Head inserted to the margin of the eyes, the 

 latter large, closely a})proached, nearly entire. Antennae filiform, 

 thii'd joint one half longer than the second. Thorax transversely 

 subquadrate. Scutellum oblong-quadrate. Elytra punctate-striate. 

 Anterior femora with a strong ti'iangular tooth, the other fe- 

 mora less strongly toothed. Intermediate and posterior tibiae 

 emarginate at the apex. Claws appendiculate. Prosternum sub- 

 quadrate; anterior ujargin of the thoracic episternum strongly 

 convex and produced. 



Type Tlujrasia marginata. 



In the genus I propose here, the eyes are very large and 

 the space dividing them is narrower than their diameter. The 

 large triangular tooth of the anterior femora and the appendi- 

 culate claws separate the genus from the other Typophorinae; 

 the very convex anterior margin of the thoracic episternum, 

 which is united with the sides of the thorax and even visible from 

 above and produced, is another chai-acter peculiar to the genus.
