76 PLATE CCXLIV. 



This rpecics has hitherto been deemed the Papilio Camilla of 

 Linnaeus, though it differs in a llight degree from the defcriptions 

 and figures of authors who defcribe only German or Swedifh fpeci- 

 mens of it. In the late editions of the Syjiema Natura, P. Camilla is 

 defcribed with P. Sibilla, a Papilio nearly allied to it, but which 

 Linnxus confidered as a diftin£l fpecies ; his defcription of Camilla 

 exprefsly faying ** angulo ani rubro." — The angulis ani, of P. Si- 

 billa*, not being of a red colour, removes it from the Engliih fpecies. 



Fabricins is of a different opinion, and in diflentlng from his au- 

 thority it is incumbent to ftate our objeilions. In the Species infec- 

 torum of that author, the P. Camilla with the Linnasan fpecific cha- 

 ra£ter, is made a variety i3 of Sibilla. The fynohyms of the two 

 infefts are ambiguous, and the references not metre fatisfaftory. 

 Among otliers he refers for P. Sibilla, to Drurys Inf. 1. tab. \b. fig. 

 I, 2, — to Roefel Inf. 3. tab. 70. fig. 1, 2, 3, — and to Schaffer 152 f. 

 fig. I, 2. The two lafl are perhaps the fame fpecies : the firft is un- 

 queftionably different. For P. Camilla he refers to Roefel tab. 33. 

 fig. 3, and this agrees with our fpecimen, except in the colours of 

 the upper furface being fomewhat paler ; fo that we may conclude 

 our Englidi Infe6l is not only the P. Camilla of Linnasus but alfo 

 the /3 Camilla of Fabricius. 



The ultimate opinion of Fabricius is however different, for in the 

 Entomologia Syfiematlca fince publifhed, Camilla and Sibilla ftands a 

 di6tin6l fpecies ; and Camilla is thus defcribed, ** alis dentatis atris 

 coeruleo micantibus : fafcia utrinque maculari alba, pofticis fubtus 

 bafi argentea immaculata." Linn. Syfi. Nat. 2. 781. 187. habitat 

 in Auflria. Thus P. Camilla will no longer agree with our infe£t^, 

 nor with that figured by Roefel^ plate 33. fig 3. But if we refer 

 to the Syftema Natura5 of Linnaeus, we difcover another error, for 



* Roefel's figure, vol. 3. tab. 70. has an obfcure red band entirely acrofs the pofterior 

 wings.— Schseffer's figure has no trace of red on that part. 



+ Erratum.— Defigned for 153 — for \^z is the German variety of Papilio Iris, Purple 



fmperor Butterfly.
