COLASPIS. 137 



(nearly black) band occupies the sides from the base to the apex, interrupting the more metallic coppery 

 colour at the disk ; scutellum small, impunctate ; elytra slightly widened towards the middle, acutely 

 pointed at the apes, surface somewhat depressed at the middle, strongly tuberculate, and transversely 

 rugose as in the preceding species, the intervals subfoveolate-punctate, of the same colour as the thorax, 

 the dark band of the latter continuing at the sides of the elytra from base to apex ; underside and legs 

 more shining, finely pubescent. 



Hab. Nicaeagtta, Chontales (Belt). 



The only specimen obtained by Belt is a male ; and I should consider it a variety of 

 C. splendida had the punctuation of the thorax been the same; this, however, is 

 much closer, and extends quite to the lateral margin, in the present species. In 

 C. splendida this part is sparingly foveolate, and the interspaces are raised in smooth 

 transverse wrinkles ; the elytra show the same closer sculpture in the species before us 

 on comparing it with the other. 



3. Colaspis gemmingeri. (Tab. VI. fig. 15.)

This species was described by v. Harold under the genus Chalcophana ; and although 

 no doubt a true Colaspis, it seems to be almost intermediate between the two genera 

 in question. The thorax, instead of being laterally dentate, is only angulate at the 

 middle, sometimes even rounded ; and the prosternum differs in the specimens before 

 me in having its base perfectly truncate or emarginate, but certainly not bilobed, which 

 would justify its being included in the genus Chalcophana. It is one of the most easily 

 recognized species of the present genus, on account of the longitudinal smooth fulvous 

 costee of the elytra and the metallic-green punctures of their interstices, which are 

 arranged in double rows. The Brazilian specimen in my collection is larger and more 

 narrowed behind than the northern forms, but does not show any other important 

 difference. The figure represents a specimen from British Honduras. 



4. Colaspis champion! 



Oblong ovate, convex, light fulvous ; the seventh and two terminal joints of the antennae piceous ; thorax 

 closely punctured, sides angulate or obscure sinuate ; elytra geminate- punctate-striate and longitudinally 

 costate. 



Length 3£ lines. 



Head very closely punctured throughout; anterior margin of the clypeus straight; thorax very closely punc- 

 tured, the margin more or less metallic green, obsoletely angulate at the middle ; elytra closely geminate- 

 punctate-striate, each elytron with about seven longitudinal costse, the interior of the punctures more or 

 less distinctly metallic green ; underside and legs light fulvous, with an obscure metallic green tint. 



Hab. Mexico, Jalapa (Edge) ; Guatemala, San Geronimo, Cubulco (Champion). 



At first sight this species seems to be identical with C. gemmingeri ; but a number of 

 differences show it to be distinct : it is separated by the antennae having piceous joints,
