Dyschirms ; 8 species of Scolyptus, Putzeys ; and 33 of Clivina, 

 almost all described by Putzeys; in all 50 species. In Mr. Masters's 

 Catalogue of Australian Coleoptera, the genus Gnathoxys of 

 Westwood is included among the Scaritidae. It seems to me 

 however, that that genus would be more correctly associated with 

 the CnemacantJoidce, and in the vicinity of Promecoderus. I 

 subjoin the description of a very distinct and curious form of 

 the Family which Mr. Froggatt lately sent me from Russell River 

 in the Cairns District of Northern Queensland. 



Genus, Steganomma. 



Mentum lai-ge, concave and corrugated on the lateral lobes, with 

 a strongly carinated median tooth. Maxillse arcuated, and 

 acutely pointed. Palpi long, slender and almost cylindrical. 

 Mandibles arcuated, rather acute, bluntly bidentate on the inner 

 edge. Labrum short, transverse, with four deep impressions in 

 front. Antennae short, submoniliform, the first joint large, the 

 last oval. Head nearly square, the eyes not visible from above, 

 two deep impressions between the eyes, a nari'ow bead along the 

 anterior margin. Thorax almost square. Elytra profoundly 

 striate, and widening a little to the apex. Anterior tibiae triden- 

 tate, intermediate unidentate. 



Steganomma porcatum, n. sp. 



Of rather elongate form, Vjlack and nitid. The head is wider 

 than long, the frontal impression large with radiating corrugations. 

 Thorax longer than broad, truncate in front, parallel-sided and 

 slightly rounded at the base, with a transverse punctured stria 

 near the apex and a deep median line from that to the base. 

 Elytra about as long as the head and thorax together, narrower 

 than the thorax at the base, a little ampliated towards the apex, 

 with six deep sharply punctured striae on each elytron with the 

 interstices smooth, convex, and gradually lessening towards the
