2^0 Mr. G. R. Waterhouse's Monograph on 



Sp. 5. D.Edwardsii {Kir. MSS.). 



D. viridis, subtus pilis albis decumbentibus : capite cupreo : tho- 

 race obscure punctulatissimo, dorso subcanaliculato : scutello 

 punctulatissimo : pedibus cupreis, tarsis viridi-cyaneis ; tibiis 

 anticis bidentatis. 



Long. Corp. 4 — 4^ lin. 



Obs. This species is rather smaller than either of the foregoing, 

 and appears to be rather more variable in colour, some being green 

 and others cupreous. It has the clypeus deeply emarginated, the pro- 

 jecting portions narrow and diverging. The head is flat above, and 

 uniformly rugose. The thorax in the male is dull, and in the female 

 rather glossy and minutely punctured. The dorsal channel is indi- 

 stinct, the lateral fovese are small, and the lateral margins are pro- 

 duced into an obtuse angle in the middle. The scutellum is finely 

 punctured. The elytra are rather short in proportion to the head 

 and thorax, especially in the males. Terminal segment of the abdo- 

 men alike in both sexes, nearly flat, (under a strong lens,) finely 

 punctured throughout, and sparingly furnished with decumbent hairs 

 towards the apex. 



The anterior tibiae are bidentate externally, and furnished with a 

 tooth-like process internally at the apex. 



Described from specimens lent me by the Rev. W. Kirby ; they 

 were procured from the Swan River. These specimens, together 

 with several others, are now in the collection of the Entomological 

 Society, having been presented with that gentleman's collection. 



Sp. 6. D. SPLENDENS, {MucLcay, in Appendix to Capt. King's Nar- 

 rative of a Survey of the Intertropical and Western Coasts of 

 Australia, p. 440.) 



D. viridis, subtus pilis albis decumbentibus : thorace obscure 

 punctulato, superne canaliculato ad latera pubescente : scutello 

 triangulari laevi : tibiis anticis distincte bidentatis, dentibus 

 piceo-rubris. 



Long. corp. 4 lin. 



Obs. In this species the head is slightly convex, thickly punc- 

 tured anteriorly, and has an indistinct transverse groove on the 

 posterior part, which is smooth ; the thorax is almost impunctate ; 

 the dorsal channel is narrow and distinct, the lateral fovese are large ; 

 the basal joint of the anterior tarsus is armed beneath with two 

 spines, one at the apex and the other near the middle. The termi- 

 nal segment of the abdomen approaches somewhat to the form of an
