726 NOTES ON AUSTRALIAN COLEOPTERA, 



curved lateral sulci. The antennae when set back reach consider- 

 ably beyond the base of the prothorax ; they are moderately stout, 

 the 2nd joint short, the rest subequal. The lateral gutter of the 

 prothorax immediately within the turned up edge is wider and 

 stronger than in most of the small Feronides (e.g. Simodontus) 

 and is continued within the basal angle and a short distance along 

 the base, and then turns and runs forward on the prothorax, 

 forming an extremely strong sulcus. The 3rd interstice of the 

 elytra bears a single puncture at about the middle of its length 

 In one of my examples the 3rd interstice has another puncture 

 near the front on one elytron only. There is no trace of an 

 abbreviated scutellar stria. 



The facies is not unlike that of Loxandrus.

As I have not a type of A.flavijoes, Thorns., I cannot form a 

 very clear notion of A. australis, Chaud., but this species seems to 

 differ from it, inter alia, in being iridescent and having antennae 

 of a uniform red colour. It is larger than any of the species of 

 Abacetus that have been described by Sir W. Macleay, those nearest 

 it in size, moreover, having the striae of the elytra punctured. 

 Drimostoma Tliouzeti and vicina^ Cast., have dark antennse, with 

 only the base pale.
