ill the genus), that it is desirable to point out their distinguish- 

 ing features. The type of C. imperialis is slightly larger, the 

 prothoracic punctures are not quite so dense; but, in particular, 

 the elytral punctures are in quite regular series, with wide inter- 

 stices, of which there are, altogether, eleven rows (including the 

 short scutellar row, and the marginal one) on each elytron; but, 

 on the present species, the rows are much more numerous, and 

 consequentlv closer together, the distance between the rows 

 being much the same as that between puncture and puncture; 

 on the disc, the distance between the rows is nowhere half the 

 width of the scutellum; whereas, on C. imperialis, the distance 

 between the rows is sometimes quite equal in width to the 

 scutellum, and never less than half its width. The antennae are 

 almost entirely black; one specimen has the palpi entirely black. 

 The metallic colours vary from coppery or golden, through green 

 and blue, to violet or purple; on the head and prothorax, they 

 are irregularly distributed, and alter from every point of view, 

 the main colours, however, being brassy-purple; on the elytra, 

 they appear to l)e in more or less regular stripes, varying with 

 the point of view, and not alike on any two of the three speci- 

 mens before me; on the type, starting from the suture, the 

 colours are green, coppery-green, purple, bluish-green, coppery- 

 green, bronzy, and l>lue, the colours more or less running into 

 each other. 



Calomela ]jima(^uliceps, n.sp. 



Pale castaneous, head with two round metallic-blue spots, 

 knees metallic-blue, parts of tibiae with a bluish gloss, six or 

 seven apical joints of antennae black or infuscated. 



Head with minute and moderately large punctures, the latter 

 more numerous between and behind eyes than elsewhere; clypeal 

 suture not conspicuously impressed, but with a few distinct 

 punctures, the clypeus itself with denser punctures than else- 

 where. Frothorax slightly more than twice as wide as long, 

 sides moderately rounded; with numerous minute and moder- 

 ately large punctures, each side with a shallow depression in 

 which the punctures are denser than elsewhere. Elytra slightly
