This species is easily distinguished from all others by the 

 elevation of the 7th interstice of the elytra at the shoulders, and 

 by the 6th stria bending in and joining the 5th near the base and 

 just behind the humeral carina. These characters are peculiar to 

 this species, and are in themselves sufficient to determine it. The 

 striae of the elytra are deep and strongly punctate ; the prothorax 

 and elytra have a bluish margin, the shades of blue being 

 variable. The female is broader, and has the elytra duller than 

 the male. 



Length 16-20 ; breadth 6-8 mm. 



A common and widely-spread species. I have it from Mel- 

 bourne, Victoria ; and from Mulwala, Condobolin, and the 

 Warialda district in N. S. Wales. It also occurs in Queensland. 



I am led to consider Flerostichus azureomarginatus, Casteln. , 

 as a synonym partly by de Chaudoir's remark^ that "it is a 

 Sarticus, and appears to me, apart from a little greater size, not 

 to differ from Fer. saphyreo^narginata ;" and partly because I 

 have a specimen from Condobolin, on the Lachlan, which agrees 

 very well with de Castelnau's description. 



Sarticus discopunctatus. 



Feronia (Sterojous) discopunctata, Chaud., Bull. Mosc. 1865, 

 iii. p. 97 ; Feronia (Sterojms) geronari, Casteln., Trans. Roy. 

 Soc. Victoria, 1865, VIII. p. 222 ; Feronia (Sterojms) honvou- 

 loiri, Casteln., I.e. p. 223 ; Sarticus ovicoUis, Motsch., Bull. Mosc. 

 1865, iv. p. 266. 



A. distinct species, and easily distinguished by its oval and 

 convex elytra, with roughly punctate striae ; the 7th stria is 

 obliterated (though usually perceptible) ; this gives the sides a 

 smooth and glossy appearance ; the lateral margins are broad and
