-elytral colours with Black tarsal clothing. In form near C. 

 leai, Blkb., and C. obscuru.s, Blkb. The punctnres of the 

 intervals are coarser and deeper than those in C. variabilis , 

 Bless., and are unusually strong. The eyes are exceptionally 

 widely separated, while the outline, seen sideways, shows less 

 convexity than in any other species known to me. Type in the 

 author's collection. 



Chalcopterus cyaneus, n. sp. 



Shortly oval, moderately convex, head, legs, and under- 

 side black, pronotum dark-blue, very nitid, elytra nitid-blue, 

 shoulders and sides with metallic reflections, antennae piceous, 

 tarsal clothing yellow. 



Head finely punctate, eyes widely separated (as in C. 

 Jiowittii, Pasc), antennae with basal joints slender, apical- 

 joints much thickened, third as long as fourth and fifth com- 

 hined, sixth to eleventh successively longer, eighth to eleventh 

 much thicker than preceding. Prothorax apex truncate, base 

 slightly sinuate, sides well rounded and converging to apex, 

 all angles obtuse and rounded, twice as wide at base as at 

 apex, closely and finely punctate, with faint indication of a 

 smooth medial line in front. Elytra wider than prothorax 

 at base, oval, convex, humeri rather prominent; seriate- 

 punctate, intervals quite flat ; the seriate punctures deep, 

 round, and rather close (four to the space of an interval), 

 intervals finely but distinctly punctate ; under-side very finely 

 striolate. Dimensions — 11 x b\ mm. 



Hah. — North- Western Australia. 



A single specimen in my collection from a forgotten 

 source. Amongst the species which combine blue pronotum 

 and elytra, with yellow clothing to the tarsi, it is nearest to 

 ■C . pulcher, Blkb., and G. hartmeyeri, Geb. From both it 

 differs in its much more nitid colour and stronger punctuation 

 of pronotum and elytra, besides being smaller. The form is 

 like C. palmerstoni, Blkb., or C. amethystinus, Fab.; the 

 punctures of elytra are arranged somewhat as in C. purpureuSj 

 Germ. Type in the author's collection. 



Chalcopterus sericatus, n. sp. 



Ovate convex, head, pronotum, under-side, and legs 

 black, elytra rose-purple, with sides and epipleurae green or 

 blue, tarsal clothing red. 



Head scarcely, or very finely, punctate, eyes with small 

 sulcus on inner margin, and separated by a distance equal 

 to the length of first joint of antennae, antennae with joint 

 three nearly as long as fourth and fifth combined, sixth to 

 eleventh subequal in length, but successively slightly widen- 

 ing. Prothorax considerably (not twice) wider at base than
