14. Diphucephala affinis, Waterh. 



Trans. Ent. Soc. Lond. I. p. 219. 



This species differs from D. furcata in being entirely of a nitid 

 metal lie-green, the under surface only being clothed with decum- 

 bent pile. The thorax is distinctly but thinly punctured in the 

 female, less so in the males, the dorsal channel and lateral foveas 

 lightly marked. The bidentation of the anterior tibiae is very 

 slight, and the teeth are distant. In all other respects the 

 resemblance to D. furcata is complete. 



Length, 4|- lines. 



Hab. — West Australia. 



15. Diphucephala Edwardsi, Waterh. 



Trans. Ent. Soc. Lond. I. p. 220; Burm. Handb. IV. p. 121. 



Entirely of a golden-green colour, and not very nitid. Head and 

 thorax minutely and rugosely punctate, the latter having the dorsal 

 channel and lateral foveae very shallow. Scutellum minutely 

 punctate. Elytra coarsely punctate in irregular rows, the punctures 

 becoming effaced at the apex. The under surface is thinly clothed 

 with decumbent pile, the pygidium very sparingly. Tarsi cyaneous, 

 anterior tibiae bidentate externally, all the tibiae armed with a short 

 triangular spur on the inner apex. The clypeus of the male is 

 deeply emarginate, but the angles diverge slightly, showing an 

 approach to the next group. 



Length, 4 lines. 



Hab. — West Australia. 



16. Diphucephala beryllina, Burm. 



Handb. IV. p. 121. 



Brassy-green, with the head, apical portion of the thorax, and 

 the external margin of the elytra of a coppery-golden lustre, 

 beneath with white pubescence, the fore tibiae not bidentate. 



Length, 4 lines. 



Hab. — Swan River.
