There are only two collections we believe in this country, 

 which possess this rare and extraordinary butterfly, and 

 it may be even doubted whether these specimens do not 

 belong to distinct species. One is in the Banksian cabinet, 

 now possessed by the Linnrcan Society, the other in that 

 of the lady of our friend J. G. Children Esq. Zoologist 

 to the British Museum. We are told the species has 

 been " made into a genus" by some continental methodist, 

 but who, according to the disreputable and slovenly mode 

 fast creeping among us, gives no definition. We have 

 elsewhere expressed our reasons for rejecting all such names 

 (North. Zool. 2. pref. lx.) y and we are thus pledged 

 to do so upon every occasion. 



Nature has so admirably disguised this insect in the 

 external form of that tribe of butterflys which she intends 

 it to represent, that it was only upon looking to its ana- 

 tomical construction, that we discovered it was a type of 

 the true PapUiomv, and not of the Frycinte. The con- 

 struction of the anterior feet, of the head and palpi, 

 and of the antennae, all which are here represented, mag- 

 nified, places this fact beyond doubt, and leaves us 

 nothing to desire but a knowledge of its caterpillar 

 and chrysalis, and of the direction of the wings when 

 the species is at rest. We suspect that like those <>t 

 Urania, they are then dejiexed.
