a, subhumeral swelling ; each with about twenty rows of dis- 

 tinct punctures, the interstices with a few minute ones, with 

 some rather coarse punctures across basal third, but com- 

 mencing some distance from suture. Inter-coxal process of 

 prosternain strongly elevated above the adjacent parts, sides 

 feebly incurved to middle, apex obtusely rounded, and base 

 distinctly notched. Glaivs strongly dentate. Length, 

 7h mm. 



Hah. — Queensland: Cairns district (F. P. Dodd). Type, 

 I. 4871. 



The apical joint of the maxillary palpi is less conspicu- 

 ously securiform than on most species of the genus. The 

 antennae are moderately long, and the species might quite as 

 well have been referred to Stethomela as to A ugomela, but 

 its general outlines are somewhat as in Ckalcomela tricolor 

 and C . uiridimicans ; the rows of elytral punctures are almost 

 twice as numerous as on other species of the allied genera. 

 A second specimen from Bundaberg (Blackburn's Collection) 

 has the upper-surface of a dark brassy-green, with the tibiae 

 almost black. 



AUGOMELA TIBIALIS, 11. sp. 



S ■ Colours brightly metallic and variable ; labrum, 

 four or five basal joints of antennae (the others more or less 

 blackish), and palpi (tip infuscated) more or less reddish. 



Head with small, irregularly-distributed punctures, 

 median line rather feeble ; clypeal suture deep, a narrow 

 impression connecting each side of it with middle of an eye. 

 Antennae not very long, but no joint transverse. Prothorax 

 scarcely thrice as wide as long, basal two-thirds almost 

 parallel-sided; with fairly numerous, scattered, distinct punc- 

 tures, larger at extreme base than elsewhere, and with 

 numerous very minute ones. Elytra slightly wider than pro- 

 thorax, sides feebly dilated behind shoulders, with regular 

 rows of fairly large punctures, becoming small posteriorly, 

 interstices with minute punctures. Inter-coxal process of 

 proste.rnum grooved towards and strongly notched at base. 

 Four hind tibiae strongly curved towards apex, with a con- 

 spicuous ridge on lower-surface. Length, 7^-8^ mm. 



9 . Differs in having four hind tibiae almost straight 

 ,and basal joint of each tarsus somewhat narrower.

 Hacker), Cape York (H. Elgner). 



Allied to hypochalcea, but with more conspicuously- 

 armed claws, the tooth of each claw is large and very distinct ; 

 on that species the tooth is but moderately distinct from 

 certain directions and quite invisible from most ; hypochalcea 

 also has a foveate expansion of a puncture (or of two or three
