iratlier fhan black, and shading off into fhe surface colour. The 

 general appearance is very suggestive of Sarotlirocrepis. 

 Near Adelaide, also Sedan (Rothe). 



N. palustris, sp. nov. Nitidus; brunneo-ferrugineus, elytris 

 abdomineque obscure infuscatis ; antennis corporis dimidio 

 brevioribus ; protborace transverso, trans basin depresso, 

 postice vix angustato, utrinque foveolato ; elytrorum disco 

 vix striato. Long. 1\ 1. 



This little insect does not seem to differ structurally from 

 ibe preceding except in having the basal joint of the male front 

 tarsi as wide as the second. The thorax is widest about the 

 middle, and regularly rounded on the sides, with the basal 

 .angles rounded off. There is a depression all across the base, 

 in which is a deep fovea on either side, and there is scarcely 

 ^ny trace of a longitudinal channel, and none at all of any 

 puncturation. The elytra have a fine sutural stria, and scarcely 

 any indication of striae outside it, but there is a deep furrow 

 near the apex of the external margin, as though the sutural 

 stria was strongly recurved. The colour is a somewhat livid 

 Thrown, with the legs paler, and there is some very obscure in- 

 fuscation (which is probably variable) about the basal and 

 apical regions of the elytra. 



A single specimen occurred to me on the banks of the Murray, 

 ;at Murray Bridge.

Ij.Jlavocinctits, s]). nov. Nitidus; piceo-niger (nonnullis exem- 

 plis capite prothoraceque rufescentibus), mandibulis palpis

 This neat little insect seems to be quite distinct from any- 

 thing previously described. The anterior margin of the 

 thorax is slightly narrower than the base, the sides are pretty 

 strongly rounded, the greatest width being considerably in 

 front of the middle where it is about one-fourth part greater 

 than the length ; the anterior margin is scarcely concave, the 

 hinder angles are roundly obtuse ; there is a well defined 

 central channel, and a large shallow impression on either side 

 behind ; the thorax has no distinct puncturation. The elytra 

 .are rather finely striated, the interstices quite flat except close 

 to the apex where they become convex, the third interstice 

 having no systematic puncturation ; the abbreviated scutellar 

 stria is wanting or indicated only b}^ a basal dilatation of the 

 second stria. The anterior and intermediate tarsi are very 

 :strongly dilated in the male, the basal joint being quite small
