THE LAMELLICORNS OF OLIVIER. 21 



Sp. 15. cornuta. Latreille makes this insect the type of his 

 genus Pacyphus ; Geotrupes excavatus, Jab., is the same 

 insect. The Baron Dejean, in his catalogue, gives it the 

 name of Calodera, I retain however, the Latreillian term, 

 being averse to changing names without there is an abso- 

 lute necessity for so doing. 



Sp. 16. glauca. This is now a Pelidnota, and is the Scar a- 

 bmus <eruginosus of the " Systema" of Linnaeus. The lat- 

 ter specific name should therefore be used instead of the 

 former. 



Sp. 19. lutea. This insect is probably a Pelidnota. No lo- 

 cality is mentioned by Olivier. 



Sp. 20. elongata. Evidently the type of a new genus ; appa- 

 rently this would be a Philochlmnea of De Jean. As that 

 genus is not, I believe, yet published, I do not adopt the 

 name, but leave it for a future describer. 



Sp. 23. plebeia. This insect according to the French cabinets 

 is an Anomala, and I think most probably is the same spe- 

 cies as Anom. scutellaris of De Jean. 



Sp. 27. rustica. It is impossible to say to what genus this 

 species is allied from the figure. I am inclined to doubt 

 the locality of Guadaloupe. 



Sp. 31. viridis. Now an Euchlora of MacLeay : the species 

 are more numerous than in the allied genus Mimela. Oli- 

 vier gives the Cape of Good Hope as its locality ; it is an 

 East Indian species. 



Sp. 32. Leii. A Mimela of Kirby. For an account of the 

 species see my monograph in the first volume of the * En- 

 tomological Transactions,' p. 116. No locality is given by 

 Olivier : all the known species are peculiar to the East In- 

 dies. 



Sp. 33. bicolor. Olivier gives this insect as from the Cape, 

 which is erroneous, as all the true Euchlorce belong to Java 

 and the East Indian continent. 



Sp. 34. suturalis. This insect I make the type of the genus 

 Stethaspis ; it is probably the Xylonichus of the French 

 cabinets. 



Sp. 35. dubia. Now a Chalepus of MacLeay : the same in- 

 sect is named geminatus by Fabricius. 



Sp. 36. angulata. No locality is given for this species by 

 Olivier. It is evidently a Bolax of Comte Fischer de 

 Waldeim, (vide ' Moscow Transactions ' in loco), and most 

 likely therefore inhabits Brazil. 



Sp. 37. bimaculata. This insect was sent to me by Dr. Es- 

 choltz. The name of Trigonostoma has been given to it 

 by the Baron Dejean; as that term is only found in the
