Length 3 lines. 



Hcib. Cochin China. 



Head purpHsh, deeply but moderately closely punctured. Labruni 

 fulvous. Antennae half the length of the body, dark fulvous, the 

 apical joints black, basal joint purplish above. Thorax transversely 

 convex, three times as broad as long, sides very deflexed and 

 rounded, narrowed anteriorly, with a narrow metallic green margin ; 

 surface very deeply and closely punctured, aureous. Scutellum of 

 the same colour, punctured. Elytra oblong, transversely depressed 

 below the base with a longitudinal row of round tubercles from 

 below the shoulder to two thirds of their length ; rest of the disk 

 punctured like the thorax, slightly transversely wrinkled at the 

 sides, purplish ; a sutural stripe, widened towards the apex, aud the 

 extreme" lateral margin metallic green. Legs and breast greenish 

 blue ; tarsi and the abdomen black. 



In my collection. 



The shorter antennae, colour of the head, and other characters 

 will easily distinguish this species from C. igneicolle, Baly. 



14. COLASPOSOMA ORNATUM, Sp. UOV. 



Oblong-ovate, convex. Black ; above aureous, rather finely punc- 

 tured ; anterior margin of the thorax, the base and sutural margin 

 of the elytra, and a narrow angulate longitudinal stripe on the disk 

 of each elytron metallic blue. 



Far. Head and thorax dark blue. 



Length 3 lines. 



Hub. India. 



Head deeply but not closely punctured, strigose at the sides ; 

 epistome rugose, punctate at the base, with an obtuse tubercle at 

 the middle ; upper part of the head aureous, space in front of the 

 antennae aud sides of the epistome metallic blue ; labrum, antennae, 

 and palpi black. Thorax three times as broad as long, its sides 

 rounded, and the anterior angles produced into an acute point ; sur- 

 face moderately deeply punctured throughout, the punctuation 

 scarcely finer at the disk than at the sides, anterior margin narrowly 

 metalhc blue. Scutellum nearly as broad as long, metaUic green. 

 Elytra scarcely depressed below the base, convex, rather more finely 

 punctured than the thorax, except below the shoulder, where the 

 punctuation is strong and the interstices are slightly wrinkled ; the 

 colour is the same as that of the thorax, extreme base and the mar- 

 gins metallic blue ; at the middle of the disk a narrow longitudinal 

 band of the same colour extends from below the base to two thirds 

 the length of the elytra, and sends off a short transverse band ante- 

 riorly at right angles towards the suture, without, however, touching 

 the latter. Legs and underside black, sides of the breast metallic 

 green. 



Of this species I possess four specimens, which, except the variety 

 mentioned above, agree in coloration, but not in sculpturing, some 

 being much more strongly punctured than others, which difference 

 might be sexual ; they may, however, possibly belong to another
