 Scarabfcus Nasicornis, Donovan, 1st edit. 



Donovan observed upon this species, which he considered as identical with the 

 European Oryctes nasicornis, that " the male is furnished with a long recurved horn on 

 the head : the female has only a small rising on that part. It is found in Europe as well 

 as China." It is evident, however, from the form of the thorax, and striation of the 

 elytra of Donovan's figure, that he had confounded two distinct species. I have little 

 doubt that the insect here figured is intended for the Oryctes Rhinoceros, although the 

 elytra are not represented as being punctured.
