Orchesia calotricha. n.sp. 



Bright ca.staneous. Densely clothed with somewhat golden 

 pubescence, conspicuously waved on elytra, and less conspicu- 

 ously so on pronotum. 



Antennae short, five apical joints forming a loosely com- 

 pacted club. Prothorax about thrice as wide as the median 

 length, sides strongly and evenly rounded, base much wider than 

 apex, with a fairly deep impression on base towards each side; 

 marginal carina on each side distinct throughout. Elytra 

 dilated for a short distance from base, and then narrowed to 

 apex, each with a feeble longitudinal elevation on basal third 

 at one third from suture. Vnder-surface strongly ridged along 

 middle. Hind spurs about as long as their supporting tibiae, 

 and slightly shorter than the following joint. Length, 31 mm. 



Hab. — Queensland: Mount Tambourine, unique (H. Hacker). 



Structurally close to 0. austrina, but with beautifully waved 

 elytra] clothing; this causes the elytra (when viewed from be- 

 hind) to appear transversely multi-fasciate. The punctures 

 are dense and fine throughout, but are slightly more conspicu- 

 ous on the front of the head than elsewhere. 



Orchesia wellingtoniana, n.sp. 



Black; parts of appendages obscurely diluted with red, spurs 

 to hind tibiae somewhat paler. Densely clothed with short, 

 dingy pubescence. 



Head almost concealed from above. Apical joints of an- 

 tennae forming a loose club. Prothorax about once and one 

 fourth as wide as the median length, sides feebly rounded from 

 base to middle and then strongly to apex, with a vague depres- 

 sion on each side of base; marginal carina on each side sub- 

 basal. Elytra the width of prothorax at base, sides feebly 

 dilated to beyond the middle, and then narrowed to apex. 

 Under surface rather strongly ridged along middle. Hind spurs 

 subequal, slightly shorter than their supporting tibiae, and dis- 

 tinctly shorter than the following joint. Length, lg-2 mm. 



flab. — Tasmania: Summit of Mount Wellington (A. M. Lea). 



Allied to 0. minuta. but without metallic gloss, pubescence 

 distinctly shorter, spurs to hind tibiae shorter (although de- 

 cidedly long), and elytra rather more dilated about the middle. 

 One of the four specimens before me has the pronotum and
