AMERICAN ENTOMOLOGY. 87 



tory, Linn^ divided his vast genua Papilio into several families, of 

 which he named the first Equitcs or Knights. This family, con- 

 taining some of the largest and most beautiful of the insect tribes, 

 was subdivided into Trojans and Greeks. The former were dis- 

 tinguished by red spots on the breast. 



The P. Pkilenor which we have already represented, belongs to 

 the division of Trojans. But this arrangement has been abandoned 

 by modern authors, who apply the name of Papilio only to the 

 Linnaean Equitcs, subdividing the genus into those which have 

 the inferior wings elongated behind in the form of a tail, and 

 those which have them simply rounded in that part. 



Much has been said and written relative to the acuteness of 

 the sensation of pain in insects, and whatever may have a ten- 

 dency to prevent acts of wanton barbarity ought certainly to be 

 encouraged, as far as it is conformable to truth, but not further. 

 The poet's assertion, that the worm, crushed beneath the foot of 

 the passenger, " feels a pang as great as when a giant dies," can- 

 not be substantiated, and proves nothing, therefore, but that the 

 author declared positively what he merely believed or imagined 

 to be true. My opinion, to the contrary of all this, is founded on 

 such facts as the following. I caught an insect belonging to the 

 present genus, and having impaled it, by passing a pin vertically 

 through its body, it escaped from my^^hand. The pin being light, 

 and no injurious pressure having been exerted on its body, the 

 insect flew, apparently with its usual facility, to a flower, and un- 

 rolling its elongated proboscis, proceeded to extract the sweet 

 fluid from the nectary, as if no mortal wound had been inflicted. 



The plant represented in the plate, is the Aqullcgia canadensis.
