as one of the most accurate artists that ever lived ; 

 as a remarkable proof of this, we find that he has 

 not failed to delineate that peculiar neuration of the 

 anterior wings which belongs only to the types of 

 Leilus. A closer affinity therefore between Papilio 

 and Leilus cannot possibly be imagined ; while its 

 remarkable hairy front points out its analogy, as an 

 aberrant type in its own genus, to Chlorisses among 

 insects, and Dasycephala among birds. So true it 

 is that the natural system ' illuminates with a flood 

 of light' every supposed anomaly, and reconciles 

 facts apparently the most inexplicable *."
