with apex somewhat acuminate; seriate-punctate (punctures 

 sometimes connected by very fine striae), the punctures in 

 striae small, evenly and distantly placed (smaller than in C. 

 iridicoloi', Bless., or C. variahilis, Bless.), the series evanescent 

 towards apex, intervals flat and sparsely dotted with very 

 minute punctures (only visible under a lens). Abdomen 

 minutely punctate, metasternum obliquely striolate. Dimen- 

 sio7is — 14 X 7 mm. 



Hab. — South Australia : Nullarbor Plains (Eucla district). 



A single specimen, kindly given me by Mr. C. French,. 

 is the most brilliantly-coloured Chalcopterus known to me. 

 The colours are so elusive that it is difficult to describe them 

 accurately. The under-side is as brilliant as the upper- 

 surface. In size, form, and colour it is nearest C. meyricki, 

 Blkb. (of which I have seen a co-type in the South Australian 

 Museum), but it differs in the following particulars from 

 C. meyricki: (1) Colours more brilliant and varied; (2) eyes 

 less widely separated ; (3) seriate-punctures much smaller, 

 more distant, intervals distinctly though minutely punctate ; 

 (4) tarsi with yellow clothing. Type in the author's collection. 



Chalcopterus latifrons, n. sp. 



Elongate-ovate, subparallel, depressed; head, pronotum,. 

 under-side, and legs black, moderately nitid, elytra 

 variegated, suture and sides green, the greater part of disc 

 purple, or green suffused with purple. Tarsal clothing black. 



Head densely punctate, space between eyes wider than 

 the length of the basal joint of antenna (wider than in C . 

 howittii, Pasc), antennae stout and gradually thickened out- 

 wards, third about as long as fourth and fifth combined, four 

 apical- joints subequal and shorter than the preceding joints. 

 Prothorax twice as wide as long, slightly sinuate at apex and 

 base, sides evenly but arcuately converging to apex, disc 

 closely punctate and very finely rugose, smooth medial line 

 evident for the greater part, anterior angles a little produced, 

 widely obtuse, posterior angles (seen from above) acute. 

 Elytra of the same width as prothorax at base, sides parallel 

 for the greater part, depressed; seriate-punctate; the punc- 

 tures in series moderately large and closely set (as large as 

 in G. variabilis, Bless., but much closer), intervals very 

 coarsely and densely punctate, and slightly rugose. Abdomen 

 nitid, closely striolate and punctate, metasternum coarsely 

 punctate and obliquely-strigose. Dimensions — 16 x 8 mm. 



Hab. — Western Australia: Shark Bay and Murchison 

 River. 



Four specimens, from Mr. C. French, are not very near 

 any of those described that combine black pronotum, obscure
