Mr. C. O. Waterhouse on Madagascar Cetoniida3. 81 



costiform ; the subapical callosity rather acute, close to the 

 extreme margin, the apex smooth. Pygidium with a few 

 punctures scattered over the surface. The anterior tibia? 

 almost simple, with scarcely any indication of teeth. Tarsi 

 very long and slender. 



This species belongs, to the same group as G. 4-macuIata } 

 W. ; — depressed, with the pygjdimn sparingly punctured. 



Coptomia modesta. 



Olivacea, nitida; thorace discrete fortiter punctato ; elytris bicostu- 



latis ; pedibus piceis. 

 Long. 6-G| lin. 



This species is close to the preceding, but is of a much 

 darker colour, and is smaller. The thorax has rather strong 

 punctures scattered over the surface, especially on the sides. 

 The elytra have each five impressed lines ; the second and fourth 

 interstices are slightly raised ; the subapical callosity is more 

 obtuse than in the preceding species. The pygidium has 

 some transverse punctures scattered over the surface, rather 

 obscure in the male. The anterior tibia? have two distinct 

 teeth at the apex in the male ; in the female there are three 

 teeth. Tarsi long and slender. 



One of the specimens has the disk of the elytra suffused 

 with blue. 



Coptomia marginata. 



Viridi-prasina vel cyanea, nitida ; thorace lateribus sat crebre for- 

 titer punctato ; elytris singulis striis sex fortiter impressis et 

 crebre punctatis, interstitiis sat elevatis Iambus, margine laterali 

 plus minusve cupreo ; pygidio parce punctato. $ § • 



Long. 6-8 lin. 



Oblong, moderately convex, usually bright grass-green, but 

 sometimes blue, with the sides of the elytra generally coppery, 

 but in the blue varieties green or lilac ; the legs pitchy. The 

 clypeus finely punctured, not very deeply emarginate. Thorax 

 not much narrowed in front, moderately thickly and strongly 

 punctured, smooth in the middle, with some fine hairs here and 

 there. Elytra with the margin near the apex and the apex 

 sparingly strigose-punctate ; the subapical callosity not promi- 

 nent, not very close to the apex. Pygidium convex, generally 

 with a few punctures. Sternal process transversely ovate. An- 

 terior tibia? tridentate, the upper tooth in the male not very 

 prominent. The abdominal impression in the male very 

 wide.
