Whether this is the Mufca Onopordinis of Linnzus, as quoted, 
we cannot exactly determine; it anfwers to his defcription of that 
infect, but he {peaks fo very concifely, that we will not venture to 
aflure ourfelves of his M. Onopordinis being our {pecies. In this and 
many other inftances we find, that though brevity is the greateft ex- 
cellence of the Linnaan defcriptions, it is alfo their moft effential 
fault. 
The fpecies may, with much psopriety, ftand under the name 
Onopordinis, as we believe it has never been figured before ; and, 
fhould the Linnzan fpecies be hereafter difcovered to differ from the 
prefent, a new name may be readily given to that infec.
