MEASUREMENTS : Length 8 mm., breadth 2 mm. 



TYPE : Specs. 28a and 286 (mould and cast) (Plate 3, figs. 

 3, 4). (B. D. Coll.) 



Family CURCULIONID^E. 

 Genus ETHERIDGEA, Handlirsch. 



? Glochinorrhynchus, Etheridge and OllifL* Type : E. australis, 

 Handlirsch. | (Triassic, Ipswich.) 



ETHERIDGEA PETRICA, sp. nov. 



Plate 3, fig. 2. 



The specimen is a nearly complete insect, resting with dorsal 

 surface uppermost ; a small portion of the right side of the pro thorax 

 and parts of both elytra are missing. The insect is rather broadly 

 oval in form, the head barely visible, being partly tucked below the 

 prothorax. 



PROTHORAX, wide, massive. 



ELYTRA, wide at bases, narrowing posteriorly, very convex. 

 In sculpture they are roughly tuberculate, the tubercles being 

 arranged in numerous longitudinal rows close together. 



MEASUREMENTS: Length ]0.5 mm., breadth 4.9 mm. 



TYPE : Spec. 31 (cast) (Plate 3, fig. 2). (B. I). Coll.) 



OBS. : This insect has elytra somewhat larger than that of the 

 genotype E. australis, but of very similar shape and sculpture, so 

 that it is unnecessary to differentiate the two genetically. An 

 examination of the type specimen of E. ttustralis shows that the 

 tubercles are in thirteen rows, but smaller and somewhat more 

 regularly disposed than in the present species. On one part of the 

 elytra the tubercles are set in an open network or areolar structure, 

 which, however, is not a cast of the exterior sculpture but a mineral 

 replacement of the chitin. The lower impression, or cast, is simply 

 tuberculate. The Rhynchophoran affinities of this beetle are 

 beyond doubt, having regard to its general form, the position of the 

 head, and the sculpture of the elytra. 



Genus MESORHYNCHOPHORA, gen. nov. 



ELYTRON, very broad at base, tapering to a fairly narrow rounded 

 apex ; surface very convex, with four strise converging distally, 

 separated by wide flat interstices. 



TYPE : Mesorhynchophora Dunstani, sp. nov.
