Hab. — Gawler; Victoria; Sydney; Queensland. 



There are some slight differences in the breadth of the 

 elytra and the amount of obliquity at the shoulders, in 

 my specimens; one of them, from Victoria, is covered 

 between the scales with an ashy exudation. The eyes 

 are less coarsely granulate than in P. frontalis. 



Onidistus, n. g. 



Rostrum tenue, arcuatum ; scrohes prEemedian^e, later- 

 ales. 8ca2nis clavatus ; funiculus 7-articulatus, articulo 

 secundo elongate, sequentibus gradatim brevioribus et 

 crassioribus ; clava subadnata. Oeuli sat magni, tenue 

 granulati. Prothorax subconicus, apice vix productus, 

 basi bisinuatus, lobis ocularibus obtusis. Scutellum minu- 

 tum, distinctum. Elytra breviter subovata vel obovata, 

 basi prothorace latiora, humeris projecta rotundata. Pedes 

 elongati ; femora clavata, basi subpedunculata, subtus 

 dente acuto instructa; tibiae compress*, flexuosae, apice 

 uncinatge ; tarsi tenuati, articulo basali elongate, secundo 

 multo breviore, tertio fortiter bilobo, ultimo longiusculo ; 

 unguiculi divaricati. Rima pectoralis inter coxas inter- 

 medias protensa, apice aperta. Episterna metathoracis 

 distincta, angustata. Abdomen, segmentis duobus basali- 

 bus amplis. 



Differentiated from its allies by the clavate toothed 

 femora, and elongate pectoral canal, open at the apex. 

 Three distinct yet homogeneous species are described 

 below, and probably some of the insects referred by 

 Montrouzier to Tylodes may belong to the genus. I have 

 another species, allied to 0. nodipennis, from New Cale- 

 donia. Cryptorhynchus pacijicus, Fauvel, although slightly 

 aberrant, may be referred to Onidistus.
