388 ON THE CARENIDES (FAM. CARABID.E), No. IV. 



obtuse, sinuosities on each side of basal lobe stronger; elytra 

 more convex, narrower at the base, more roundly ampliate behind 

 the shoulders, lateral declivities more rounded — almost hiding 

 the border in the middle when viewed from above. From C. 

 sapphirinum, Bates, it differs by facies; the labrum smaller and 

 more deeply emarginate; clypeus more deeply and evenly emar- 

 ginate; anterior margin of head, outwards from intermediate 

 angles of clypeus, forming an even oblique curve (not curving 

 decidedly forward in middle as in G. sapphirinum). The mandi- 

 bles are flat on the upper surface as in C. superbnm. 



Genus Monocentrum. 



MONOCENTRUM LONGICEPS, Chaild. 



I have found a species of Monocentrum in New South Wales, 

 near Grenfell and Urana, which seems to be M. longiceps, Chaud. 

 The late Mr. Geo. Barnard found M. longiceps at Coomooboolaroo, 

 Dawson River, Queensland.
