SPECS. 23a, 236 : Another individual and its counterpart (B.I). 

 Coll.), measures 43 mm. by 15 mm. This is apparently a portion of 

 a wing similar to that of Mesotitan, but much smaller, probably 

 not exceeding four or five inches in total length. The cross-veins 

 are arranged in a single parallel series between two main veins 

 (possibly Sc and R), but between a number of descending branch 

 veins they are densely packed, forming a close polygonal network, 

 as in Titanophasma. The specimen is not sufficiently characterised 

 to merit a name. 



Order COLEOPTERA. 



Family ELATERID^ (V). 

 Genus ELATERITES, gen. nov. 



ELYTRON, elongate oval, tapering posteriorly, closely resembling 

 that of a recent " Click" beetle ; no definite sculpture visible, except 

 a slight roughness of the surface. 



TYPE : Elaterites wianamattensis, sp. nov. 



ELATERITES WIANAMATTENSIS, sp. nov. 

 Plate 3, fig. 5. 



ELYTRON, complete cast of right one ; appears to have been 

 slightly roughened or perhaps pubescent. 



MEASUREMENTS : Length 6.5 mm., greatest breadth 1.8 mm. 

 TYPE : Spec. 30 (Plate 3, fig. 5). (B. D. Coll.) 



Family MALACODERMIDJE. 

 Genus METRORHYNCHITES, gen. nov. 



ELYTRON, elongate oval, with three strong longitudinal ribs, 

 one roughly parallel with inner border, and extending to tip, the 

 other two roughly parallel with outer border and meeting the first 

 rib at two separate points near apex. Closely resembles elytron of 

 recent genus Metrorhynchus inhabiting Southern Queensland. 



TYPE : Metrorhync-hites sydneiensis, sp. nov. 



METRORHYNCHITES SYDNEIENSIS, sp. nov. 

 Plate 3, figs. 3, 4. 



ELYTRON, nearly complete cast and mould of left one ; besides 

 the three ribs referred to above, the surface of the elytron appears- 

 to have been finely granular.
