LEPIDOPTERA : STRUCTURE. 395 



are confounded together whilst on the wing. In like man- 

 ner, Castnia cronis of Surinam was actually described by 

 Cramer as the female of Papilio cronis. Analogies equally 

 strong exist amongst the species contained in the separate 

 sections ; thus Euterpe teria, belonging to the Pierides, was 

 actually placed, by Latreille and Godart, in the genus Papilio, 

 to some of which, in its black wings and red spots, it bears 

 so great a resemblance. Another, and still more remote, 

 species of analogy exists between some Lepidoptera and 

 the insects belonging to other orders ; thus the species 

 of Sesia and JEgeria so much resemble some bees and wasps, 

 that they have obtained the names of wasp, hornet, and bee- 

 sphinxes ; and indeed we find such an author as Professor 

 Bradley so far deficient upon this subject as to admit into his 

 work a quotation to the following effect : — " There are gra- 

 dual alterations from a perfect moth to the bee kind ; and 

 indeed, if we examine the 2Gth plate, we may find a just pro- 

 portion from one to the other. The antennae of all are alike, 

 and their bodies are just different enough to be distinguished 

 from one another" — the figures referred to representing the 

 Macroglossa stellatarum (the humming-bird sphinx), Trochi- 

 lium fusiforne (the narrow bordered bee-sphinx), Trochilium 

 homhyliforme (the broad-bordered ditto), and Bombus ter- 

 restris (the humble bee), of which last the antennae are 

 blameably made like those of the preceding insect, that they 

 may the better correspond with the text ! The species of 

 jEgeria have, in like manner, received a series of names, 

 illustrating their striking analogy with many other insects 

 of diff'erent orders ; thus we have yEgeria Tipuliformis, 

 ^ger. Chrysidiformis, &c. ; and the Glaucopis coarctata, in 

 the coarctate form of its abdomen, exhibits a strong resem- 

 blance to an ichneumon. As to the analogies between the 

 Lepidoptera and other more distinct tribes of animals, it will 

 suffice to state, that the humming-bird moth, and many
