VI. — Description of a new species of Cetoniidse. — 



By James Wood-Mason. 



(Bead Jan. 5th, 1876.) 



Sub-fam. GOLIATRIN^l. 



Heterorhina Roepstokffii. 



P. A. S. B., 1876, p. 4. 



Tota nigra, nitida ; clypeo ut in H. Childrenii ; elytris singulis macula 

 parva subquadrata vel subovata alba. 



Long, iota maris unic, 15 mm. ; fcem. \h\ mm. 



Wholly black, shining, somewhat attenuated ; clypeus as in H. Child- 

 renii ; a small subquadrate or subovate spot — dirty straw-coloured in the 

 dead but brilliant white in the living insect — occupies about the second 

 fourth of the length and the external or anterior two-thirds of the breadth 

 of each elytron. The fore tibise are subbidentate in the female, and the 

 abdomen of the male is longitudinally channeled below. 



The species belongs to the same little group as UH. bimacula, confu- 

 sa, Cuvera, and Childrenii, from all of which it differs in being wholly 

 black, no part of its body being coloured blood-red as in those species, in 

 its slenderer and more attenuated form, and in the smaller size of the 

 patches on the elytra ; but it agrees with the last-named in the structure 

 of the clypeus and in the form of the mesosternal process. 



In slenderness of body, H. Moepstorffii somewhat approaches H. mod- 

 esta, Wallace — a species belonging to a different section of the genus. 



Hab. — South Andaman, where it was collected by Mr. F. A. de Eoep- 

 storff.
