174 OBSERVATIONS ON 



this species an inhabitant of South America ; it comes from 

 the Old World, — from Guinea. 



Sp. 4. micans. Now a Dicronorhina of Hope. Mr. Strachan 

 has brought to England with him a new species of this 

 genus from the vicinity of Sierra Leone. It most probably 

 will appear in an early number of the 'Entomological 

 Transactions' of London. ■ 



Sp- 6. nigrita. Olivier states his belief that this insect is 

 only a variety of Macronota Chinensis ; Col. Whithill ob- 

 tained it from the Concan, and from an examination of the 

 specimen in the British Museum I consider it as a distinct 

 species. 



Sp. 7. corticina. This is still a Cetonia, and is the Cet. pur- 

 purascens of Fabricius. 



Sp. 9. bimaculata. This insect is not a Gnathocera, but a 

 Coryphe of Gory; the specific name of \flavomaculata Fab., 

 should take precedence of bimaculata. 



Sp. 10. guttata. Olivier describes this species as inhabiting 

 South America. I have received it from Sierra Leone. 



Sp. 11. aulica. Still a Cetonia. It appears, however, to 

 afford ample characters for a sub-genus. 



Sp. 13. marmorea. This is now a Gymnetis, MacLeay. Mr. 

 Kirby has suggested the adoption of another genus, named 

 by him Marmorina, to which this species with several 

 others ought to be attached. 



Sp. 16. carnifex. Olivier's locality for this species is South 

 America ; it inhabits the Cape of Good Hope, and belongs 

 to the genus Diplognatha. 



Sp. 1 7. fuliginea. This is now an Oplostomus of MacLeay. 

 For the details consult his ' Illustrations of the Zoology of 

 South Africa,' lately published. Olivier gives no locality ; 

 I have received it from the banks of the Gambia, and Mr. 

 MacLeay from the Cape. 



Sp. 23. elongata. Now a Cyclidius of MacLeay, of which 

 this species is the type. Cetonia axillaris, Dupont, be- 

 longs to the same genus. Olivier does not mention the 

 country from which he received it : Mr. MacLeay and 

 Mons. Gory give it as a South American insect. 



Sp. 31. quadrimaculata. A Dicronorhina, Mihi. The ori- 

 ginal specimen from which Fabricius and Olivier described 

 the above insect is now in my possession, and I consider 

 it as the female of Goliathus Daphnis of Buquet ; Mr. 

 MacLeay however, regards it as distinct. 



1 The insect alluded to at Cetonia 4, appears to be one of the Goliatidce, 

 and is the male of Cet. torquata, Fab. ; in its characters it seems mediate 

 between Meet/norhina and Dicronorhina.
