Head with tliree small shining spaces ; punctures very 

 dense but well-defined. Antennae moderately stout, extending 

 to second segment of abdomen, sixth to tenth joints dilated at 

 apex of each. ProtJioraT with somewhat larger punctures 

 than on head, on apical portion sparse and more sharply 

 defined. Elytra with a vague depression behind each shoulders- 

 punctures about base much as on head, becoming smaller and 

 less crowded posteriorly. Length, 2J-3J mm. 



Hah. — South Australia (Blackburn's collection) : Mount 

 Lofty, Kangaroo Island (J. G. O. Tepper) ; Victoria: Mon- 

 bulk and Emerald (H. H. D. Griffith from E. Jarvis). Type, 

 I. 3243. 



In some respects close to aenea, but prothorax not trans- 

 versely impressed. The prothoracic punctures, which are un- 

 usually conspicuous in front, from certain directions appear to 

 each have a small central pit, from other directions each 

 appears to have a feeble median elevation. On the majority 

 of species of the genus the prothoracic punctures are more or 

 less similar, but being more crowded their individual sculpture 

 is less distinct. An occasional specimen has a purplish gloss. 



Two males before me probably belong to this species ; they 

 are of a brassy-green, becoming of a vivid-green on head and 

 almost purplish towards apex of elytra ; the abdomen is less 

 convex, there is a feeble transverse impression on the fifth 

 segment, and the antennae (especially on the apical half) are 

 thinner and extend to the tip of the abdomen. 



TOMYRIS DUMBRELLI, n. Sp. 



Of a metallic but rather dull green, becoming brassy on 

 parts of under-surface ; labrum and appendages flavous-red, 

 but many of the antennal joints tipped with black. Moderately 

 clothed with very short pubescence, but elytra with some 

 longer hairs scattered about. 



Rather narrow ; densely covered with small asperate 

 punctures. Antennae rather thin, extending to about middle 

 of abdomen. Length, 2| mm. 



Hah. — New South Wales: Sydney (British Museum from 

 C. Darwin), Galston (S. Dumbrell). Type, I. 3474. 



A small dull-green species, smaller than viridula, and 

 prothorax not transversely depressed. The prothorax, when 

 viewed obliquely, appears to have an extremely feeble median 

 parting of pubescence. The three specimens before me appear 

 to be all males, as the abdomen, although without an apical 

 fovea, is rather less evenly convex than is usual in females. 



TOMYRIS PICTICORNIS, U. Sp. 



(S . Bright metallic-green, parts of under-surface brassy- 

 green ; labrum and appendages flavous, but tips of five apical
