A beautiful insect ; the metallic parts are sharply- 

 defined at the edges and the suture, but then rapidly fade 

 into the general colour, the elytral punctures from some 

 directions have a watery look, and from others a purplish 

 gloss; parts of the under-surface have a metallic gloss. 



COLASPOIDES RARA, U. Sp. 



9 . Dark metallic-blue, in places with a greenish or 

 coppery gloss; parts of antennae and of palpi obscurely 

 diluted with red. 



Head rather convex, not depressed between eyes, median 

 line rather strongly impressed at base but feeble elsewhere ; 

 punctures between eyes rather dense and of moderate size, 

 smaller and sparser towards base, and much smaller and 

 denser on front of clypeus. Eyes rather narrow. Antennae 

 not very thin, third and fourth joints subequal. Frothorax 

 strongly convex, rather lightly transverse, with the apex 

 scarcely as wide as the median length, sides strongly rounded 

 and with very narrow margins; with not very dense and 

 rather small punctures, and some much smaller ones scattered 

 about. Elytra with punctures much as on prothorax, except 

 that in places a feeble seriate arrangement may be noticed, 

 apical slope with distinct sutural and lateral striae, but else- 

 where without same. Flanks of iwosternum somewhat 

 wrinkled, and with rather small and unevenly distributed 

 punctures; episterna strongly rounded in front, and with 

 deep sutures. Femora unarmed; tibiae conspicuously canali- 

 culate along upper-surface. Length, 9 mm. 



Hah. — South Australia. Type (unique) in Macleay 

 Museum. 



A well-marked species with the front of the prosternal 

 episterna more strongly rounded than on any other species 

 of the genus, or perhaps of the subfamily. 



COLASPOIDES QUIETA, n. Sp. 



9 . Of a rather dingy flavous, prothorax with a vague 

 metallic gloss and in places feebly infuscated, suture narrowly 

 infuscated ; parts of under-surface more or less deeply 

 infuscated. 



Head with rather dense punctures of moderate size. 

 Antennae rather thin, second joint more than half the length 

 of third, the latter slightly shorter than fourth. Prothorax 

 with rather dense punctures of moderate size, becoming 

 denser on sides than on disc. Elytra with semi-double rows 

 of moderate punctures, becoming condensed into single rows 

 in deep striae posteriorly, near shoulders feebly transversely
