LAMELLICORNS OF OLIVIER. 319 



Sp. 27. Ajax. Although Olivier does not give the country 

 this insect inhabits, there can be little doubt of its occurrence 

 in the Brazils. Most likely a Strategus of Kirby. 



Sp. 34. Barbarossa. Under this name, more than one 

 species will be found in our English cabinets. It is singular 

 that the male has not yet been published, and appears to be 

 unknown to the continental Entomologists. 



Sp. 35. Quadri-spinosus. The insect named by Mr. Kirby 

 as quadri-spinosus, appears to be of a different genus to the 

 Fabrician species ; the former is a Brazilian, the latter an 

 Asiatjc insect, and belonging to the genus Oryctes of Illiger. 

 The same specific name was the cause of the mistake which is 

 printed in my late Manual. 



Sp. 37. Militaris. I am totally unacquainted with Oli- 

 vier's species named Militaris ; I therefore give it for the pre- 

 sent as a Xylotrupes. From the figure, I should say it was 

 a Brazilian insect. 



Sp. 39. Augias. I esteem this insect only as a variety of 

 Oryctes Rhinoceros, Fab. Apparently it was first described 

 from Dufresne's cabinet. His collection was purchased by the 

 Scotch, and forms the nucleus of the Entomological collection 

 at the Museum in Edinburgh. 



Sp. 40. Monoceros. This insect is most likely the female 

 of Oryctes Boas. 



Sp. 48, Cadmus. Now the type of Mr. Kirby's genus 

 Henodon. Olivier mentions Senegal as its true locality ; I 

 have some doubts however respecting its original country .'' 



Sp. 49. Areas. This insect appears to unite the CetoniadcB 

 and the genus Syrichtus of Kirby. 



Sp. 50. Juvencus. This insect may be considered as the 

 type of a new subgenus. 



Sp. 51. Zoilus. Now probably a A^o^TOjo^s ? There are 

 several species of Xylotrupidw which require further subdivi- 

 sion. The above insect approaches in its characters to Ccelosis, 

 Kirby, but is evidently generically distinct. 



Sp. 5Q. Melampus. From Olivier's figure, I can only con- 

 sider this insect as the female of a Xylotrupes. In appearance 



b Since writing the above, I find that iMr. Kirby's insect named as the type of 

 Henodon, and marked with a query as Olivier's species Cadmus, is certainly 

 another subgenus ; the characters of botli will be detailed amongthe new genera.
