188 ON THE AUSTRALIAN CLIVIXIDES, 



Although I have a suspicion that C. heteroyena will ultimately 

 prove to be identical with C. angustula, the evidence before me 

 is insufficient to enable me to feel absolutely certain about this; 

 I therefore append a translation of the description of C. heterogena. 



The anterior elevation, well marked and rather short, is 

 separated from the vertex by a punctate impression of but little 

 depth; the svuiimit of the head bears a wide longitudinal im- 

 pression containing some large punctures ; the punctures on 

 each side near the eyes are of the same size. 



The eyes, of which only half is distinct, are very prominent. 

 The prothorax is square, a little sinuate on the sides, as broad in 

 front as behind; all the surface, except the anterior part in the 

 middle, is covered with very distinct punctures. 



The elytra are very elongate [and] cylindrical; their rounded 

 shoulders are reflexed; they are of a piceous brown, but their 

 external border, the suture before and behind, and the shoulders 

 are of a testaceous colour. The fourth stria turns out at the 

 base and reaches the eighth interstice. 



The under surface of the body is black; the legs, except the 

 upper side of the femora, the palpi and the antennte are testaceous. 

 The anterior tibife have externally two very long teeth and a 

 small not very distinct tooth.

Australia. One specimen belonging to M. de Chaudoir, who 

 received it from M. Melly. 



The specimen noted under form " e " of C. angustula, Putz., 

 (vide post), from Windsor, N.S.W., agrees in all respects with the 

 description of 6'. heterogena. If "e" be merely a form of C, 

 angustnla, then that species must sink to a synonym of C. heterogena; 

 but this is a point which, with the identity of C. difformis, Putz., 

 and C. odontomera, Putz., cannot be determined till exhaustive 

 series of specimens of C. angustula and allied forms, from 

 various localities (including Rockhampton) on the east coast of 

 Australia, have been examined.
