and unique specimen, or that it is one of the later described 

 species. It is possible that the author has misled some col- 

 lectors in the confusion of cupriventris with cujyreus. 



Chalcopterus puncticollis, Hope. 



Slightly obovate, head, underside, legs, and tarsal cloth- 

 ing black, pronotum dark metallic-green (in old specimens 

 black), sometimes with slight purple reflections, elytra vari- 

 coloured, chiefly cyaneous, the sutural region more or less 

 golden or purple, sides and epipleurae purple. 



Head closely and strongly punctate, eyes scarcely sul- 

 cate, separated by a space equal to the length of the basal 

 joint of antenna, antennae with joint three nearly as 

 long as fourth and fifth combined, sixth to tenth 

 subequal in length but successively wider, eleventh 

 acuminate. Pronotum much wider at base than at apex, 

 sides arcuate, the lateral carina seen from above throughout, 

 anterior angles produced, posterior obtuse, disc rather 

 strongly, not closely punctate, with a fine Isevigate central 

 line. Elytra wider than prothorax at base, very little convex, 

 widest behind middle, striate punctate, each elytron with eiglit 

 stricB continuous from base to apex (besides a short scutellary 

 stria), more deeply impressed at sides and apex, the punctures 

 therein large, round, and close (larger and much closer than 

 in C . iridicoJor, Bless.), intervals convex, closely and strongly 

 punctate. Abdomen and sides of metasternuni strongly 

 punctate, the prosternum coarsely, their episterna more finely 

 punctate; hind tarsi with basal joint nearly as long as the 

 rest combined^ claws red. Dimensions — 11-16 x 6-8| mm. 



Hah. — Western Australia: Perth. 



A common species, found in most collections, differing 

 from C . purpureus, Germ., by its greater size, arcuate thorax, 

 darker colour, and stronger punctuation of its upper-surface, 

 while suturalis, Pasc, has a shining-black prothorax, and the 

 intervals of elytra almost impunctate. 



Chalcopterus maximus, n. sp. 



Widely o\ate, head and pronotum metallic — sometimes 

 coppery — elytra purple and green intermixed, the suture, 

 lines of punctures, and epipleuras greenish, sides golden-green, 

 under-side, legs, antennae, and tarsal clothing black. 



Head closely, rather finely punctate, eyes without definite 

 sulcus, space between them as wide as the basal antennal 

 joint; antennae very stout, rather short, scarcely enlarged 

 apically, joint three shorter than fourth and fifth 

 combined, sixth widest of all, shorter then the succeeding, 

 seventh to tenth subequal, eleventh nearly as long as
