Lea — ()M Australian Coleopticra 281 



Head with irregularly distributed puiictui-es, sharply defined only on clypeus. 

 Prothorax twice as wide as long, sides almost evenly rounded, angles slightly 

 armed ; with large and irregularly distributed punetures, leaving numerous small, 

 subtubereular, impunetate elevations. Scutellum impunctate. Elytra rather 

 wide, slightly diminishing in width from shoulders; with large, round, deep 

 punetures, irregular about base, more or less lineate in arrangement elsewhere. 

 Legs stout ; femora edentate. Length, 8-9 mm. 



Hah. North-western Au.stralia : Forrest River f-T. Clark from W. C'raw- 

 shaw). Type, I. 11096. 



Readily distinguished from all other described species, except A. carinatus, 

 by the striped elytra and from \\\e striped variety of that species by the punctures 

 between the first and second stripes being in two rows only, and individually much 

 larger. The sides of the protliorax at first glance appear to be quite evenly 

 rounded, but on clos(> examination faint indications of teeth may be traced on two, 

 of the three, specimens before me. 



TOMYRIS SUBLAETA Lea. 



Four specimens, from the Blue Mountains, evidently belong to this species, 

 but differ considerably from the types in colour ; one has the head, except for a 

 vivid green strip in front, prothorax, scutellum and elytra, of a beautiful golden- 

 red; the others have the head, except at base, and scutellum green, with a wide 

 median portion of the prothorax and elytra golden-red, or brassy. 



TOMYRIS NIGRA sp. nov. 



9 Black, with a slight bronzy gloss, less distinct on the elytra than else- 

 where, parts of four basal joints of antennae, basal joints of palpi and knees 

 reddish. Elytra with moderately long and not very dense, suberect, white 

 pubescence ; much ,' horter but denser elsewhere. 



Head with crowded, asperate punctures. Antennae with five apical joints 

 stouter than usual. Prothorax with a shallow and irregular but distinct impres- 

 sion across middle ; punctures slightly larger than on head. Elytra with large, 

 irregular ]-)unctures, larger (especially behind shoulders) at basal third than 

 elsewhere, but becoming rather small about apex. Length, 5-25 mm. 



Hah. New South Wales: Blue Mountains (Dr. E. W. Ferguson). Type 

 (unique), I. 11993. 



In size and colour much like the female of T. ohscura, but the punctures are 

 much larger and more sharply defined, the five terminal joints of antennae are 

 wider and the clothing is different ; in my table it would go with T. viUo.sa, but 

 differs from the female of that species in being considerably larger, black with 

 but a slight metallic gloss, and with much larger elytral punctures.
