and thin. Frofliorax with a conspicuous, shining, transverse, 

 feebly elevated, median ridge, marking the front edge of the 

 postmedian depression, this well defined ; punctures rather 

 larger and better defined than on head. Elytra with dense 

 and rather small, but well-defined punctures, becoming 

 smaller posteriorly. Fifth segment of ahdomen transversely 

 impressed. Length, 3 mm. 



9 . Differs in being of a golden-red or golden-purple, 

 with the clypeus green, antennae shorter, and abdomen more 

 convex, with the fifth segment not transversely impressed. 



Hah. — South Australia: Nuriootpa (J. G. O. Tepper). 

 Type, I. 3242. 



A minute and rather narrow species, readily distinguished 

 from all previously described ones by the conspicuous ridge 

 (interrupted in middle on one specimen) across prothorax. 

 On each of the three specimens before me the small median 

 shining space on the head is lengthened into a feeble carina, 

 but it is probably not to be depended upon. 



TOMYRIS INCISA, U. Sp. 



PI. viii., fig. 108. 



S ■ Bright metallic-green ; under-surface brassy-green, 

 labrum and appendages (black tip of antennae excepted) 

 flavous. Clothed with short, golden pubescence, denser on 

 elytra than elsewhere. 



Head with dense, asperate punctures. Antennae thin, 

 extending to middle of abdomen. Frofhorax with transverse 

 depression rather well defined ; the punctures on it much as 

 on head, elsewhere they are mostly individually distinct. 

 Elytra with smaller punctures than on head, becoming still 

 smaller posteriorly. Fifth segment of ahdomen with a con- 

 spicuous median fovea, l^ecj^ rather stout; four hind tibiae 

 with subapical notch very conspicuous on each; four front 

 tarsi with basal joint distinctly inflated. Length, 3-3| mm. 



Hah. — Western Australia: King George Sound (Macleay 

 Museum), Mount Barker (R. Helms), Darling Ranges (A. 

 M. Lea). Type, I. 3481. 



In general appearance like small specimens of laeta, but 

 prothorax transversely depressed, and the four hind tibiae 

 each much more conspicuously dilated towards the apex, and 

 with the subapical notch unusually conspicuous, certainly 

 much more so than on elegantida , imprex.'^irolUs, viridida, or 

 any other green species in the Museum. A specimen from 

 Bridgetown is smaller (2f mm.) and thinner, but otherwise 

 agrees with the type. The male of the Macleay Museum is 

 more of a golden-green than the type, and is mounted on a
