posterior declivity ; this is rather abrupt and thickly studded 

 with small tubercles, the larj^est of which are almost apical ; 

 there are other obtuse tubercles on the third, lifth and seventh 

 interstices. Most of the specimens before me are encrusted with 

 mud.

Referred by Erichson to Acalles,^ but belongs to the group 

 of Poropterus represented by such species as exitiosus aaid 

 bisignatus ; although in its deeply sulcate basal segments of 

 abdomen 2 it is unique in the genus. There is usually a small 

 shining tubercle on each side of the scutellar region, and the 

 elytra when abraded aippear to be vermiculate-tuberculate. The 

 derm obliquely behind the shoulders is occasionally diluted with 

 red. The two spots on each side of the head and the four 

 luteous spots placed transversely on the prothorax are usually 

 indistinct ; and the median line is so faint as to be practically 

 invisible. The apex of the prothorax appears to be feebly bitid, 

 but this is due almost solely to the clothing. 



The male has the rostrum stouter than in the female, with 

 denser and coarser punctures, and hais scales almost to the 

 antennae instead of at the base only. 



Specimens are to be taken under logs, or crawling over them 

 at night time. I have specimens from Frankford, Ulverstone, 

 Wilmot and Stanley in Tasmania, as well as from King Island, 

 and have seen the type.
