C. arthuri, Blkb., seems to me only a variety of C. 

 intermedius, Blkb., if my specimens are correctly identified. 

 I have C. arfhurl taken in Brisbane and compared with co- 

 types in Mr. Lea's collection. These exactly correspond with 

 specimens of C. intermedius, Blkb., sent by Mr. Blair, com- 

 pared with type. 



C. vinosus, Pasc, is the species identified for me by 

 Blackburn as probably C. resplendens, Bois., but on what 

 evidence I do not know. 



C. suturalis, Pasc. =(7. sulcipennis, Hope, fide Blair, 

 who has compared the types. 



C. crossus, Blkb. Mr. Blair notes the slight difference 

 in the width between the eyes of crcesus and mercurius, to- 

 gether with some colour difference, but he concludes : ''Should 

 be inclined to doubt specific distinction of crcesus and mer- 

 curius, but have only unique type of each." 



C. simius, Blkb. I cannot consider this otherwise than 

 a variety of the widely-distributed C. a-ffinis, Bless. Like all 

 common species the varieties are very puzzling, and I have 

 often seen specimens of a-ffinis that correspond to the descrip- 

 tion of simius. This is confirmed by the specimen which Mr. 

 Blair sends as compared with type of sim,ius, which I have 

 no hesitation in calling C . affinis, Bless. 



The following are the descriptions of the new species : — 



Chalcopterus cupriventris, n. sp. 



Elongate ovate, head and pronotum bronze-green (the 

 former sometimes more obscure), elytra purple (sometimes 

 with coppery reflections), with the suture and punctures 

 green, prosternum black, rest of the under-side metallic-green 

 or copper, coxae and base of femora reddish, legs black, tarsal 

 vestiture yellow. 



Head closely punctate, eyes distant the length of basal 

 joint of antennae and bordered by a fine sulcus, antennae with 

 joint three equal to fourth and fifth combined, seventh 

 to tenth successively longer and thicker than the pre- 

 ceding, eleventh more elongate but narrower than 

 tenth. Prothorax truncate at apex, slightly sinuate 

 at base, twice as wide at base as at apex, sides 

 arcuately converging to apex, anterior angles widely obtuse, 

 posterior (seen from above) acute, irregularly but distantly 

 punctate with indications of a smooth medial line. Scutellum. 

 triangular, greenish, smooth. Elytra convex, subparallel, 

 wider than prothorax, striate punctate, punctures on middle 

 series small, larger on lateral series, rather closely set (about 

 four punctures to the width of an interval), intervals flat on 

 disc, very slightly convex towards sides, minutely but evidently
