Description of Twenty new Species of Australian Coleop- 

 tera, belonging to the families Cicindelidce and Cetoniidce, 

 by William MacLeay, Junr., Esq., M.L.A. 



[Read 4tli August, 1862.] 



The following Paper contains descriptions of Twenty hitherto 

 undescribed species of Golenptera, principally selected from 

 a large collection of Insects, which, as I mentioned at the 

 last meeting of this Society, I have lately received from Port 

 Denison. I have not, however, confined myself to Insects from 

 that locality, bnt have included several species from other parts 

 of Australia, which I believe to be undescribed. 



Family CICINDELID^. 

 Genus Megacephala, Latr. 

 Subgenus Teteacha, Hope. 

 1. — Tetracha humeralis. 

 Viridi-ajnea mandibulis labro antennis pedibus anoque ferru- 

 gineis, elytris atro-cyaneis granulatis punctorum linea 

 irregulari subsutnrali pone scutellum retroi'sum incurva 

 vittaque ferruginea marginali pone humerum dilatata. 

 Long. 9 lin., lat. Sj lin. 

 Hab. Pox"t Denison. 

 The head, thorax, and under part of the body are of a brassy 

 green, tinged towards the edges with blue ; the elytra, which are 

 roughly granulated, are of a very dark blue, without metallic 

 brilliancy ; an irregular line of small punctures extends along the 

 whole length of each elytron at a short distance from the suture, 

 turning inwards at the base, and forming a second line for a 

 short distance near the scutellum. The margins of the elytra from 

 the shoulders to the apex are of a reddish yellow, a patch of the 

 same colour extending from the marginal vitta, almost into the 

 centre of the disc, a little behind the shoulders. The mandibles, 

 labrum, antennas, legs, and terminal segment of the abdomen, 

 are ferruginous.
