MESORHYNCHOPHORA DUNSTANI, sp. nov. 



Plate 1, fig. 7. 



ELYTRON, 15 mm. long, 5 mm. wide. The specimen shows 

 practically the whole of the right elytron. The five flat interstices 

 shown in the cast are granulate near the apex, and minutely tuber- 

 culate on their sides near the base. On the exterior (mould) the 

 interstices are only faintly impressed. The Rhynchophoran affinities 

 of this form do not rest upon such sure grounds as those of the 

 preceding species, but are based solely upon the shape and convexity 

 of the elytron. 



TYPE : Specs. 21a (Plate. 1, fig. 7) and 276 (mould and cast). 

 (B. D. Coll.) 



INSECT A IXCERT.E SEDIS. 



SPECIMENS 26A and 26s (mould and cast). Portion of a roughly 

 granulate elytron, broken off longitudinally ; length 11.5 mm. 

 Probably a Curculionid. 



SPECIMENS 29A and 29B (mould and cast). Body of an elongate 

 oval beetle with elytra in situ ; roughened sciilpture. Length 9 mm., 

 breadth 4 mm. Too indistinct for classification. 



SUMMARY OF ST. PETER'S RESULTS. 



The following is a list of the fossil insects named and described 

 from the St. Peter's beds : 



ORDER. 



GENUS. 



SPECIES. 



Blattoidea 



Protorthoptera 



Coleoptera 



Notoblattites, gen. nov. . . N. subcostalis, sp. nov. 

 Mesotitan, gen. nov. . . M. giganteus, sp. nov. 



Elaterites, gen. nov. . . E. wianamattensis, sp. 



Metrorhynchites, gen. nov. M. sydneiensis, sp. nov. 

 Etheridgea, Handlirsch . . \ E. petrica, sp. nov. 

 Mesorhynchophora, gen. nov. M. Dunstani, sp. nov. 



Omitting the unnamed fragments we thus have representatives 

 of three orders, totalling six genera five of which are new and six 

 species. 



The evident abundance of Coleoptera within this fauna and that 

 of Ipswich is a point worthy of note. Our records suggest that at 

 least seven families were represented in these Mesozoic beds, viz., 

 five at Ipswich, and three at St. Peter's, the Curculionidae being 

 present in both. Records of Coleoptera have so far not been traced 

 any further back than the Triassic.
