PLATE CCXXXVIII, 



S9 



defcription of Papilio Hyale feems to agree with the fiQitious 

 P. Palano of our colteaions, and the fpecimen in the Linnsean 

 cabinet places it beyond conjecture. 



Fabricius has not correcled the errors of former authors on this 

 fubjecl: ; even in his laft work, Syjl. Ent. he adds to the fpecific 

 defcription of his P. Hyale, " Mas margine alarum nigro immacu- 

 lato, fcemina maculato" *, by this it is evident he alludes to the 

 clouded orange, for it is not fo in the Linnaean infect ; the broad 

 bar of black being conftantly fpotted in both fexes. We have alfo 

 obferved that the rare variety with white wings is only the female ; 

 that which is yellow is the male : the fame is obferved alfo of 

 Papilio Rhamni, or Brirnftone Butterfly; and as the males of all 

 infects are more abundant than the females, and the males of P. Hyale 

 are rare, the variety, or fex with white wings rauft be extremely fo. 

 Thefe have been taken in a clover field in the month of Auguft, in 

 company with the clouded orange. 



It may be proper to clofe this defcription with a few obfervations 

 on the true Papilio Palasno, as the fubjecl; before us has hitherto 

 pa{fed under that name. Linnaeus fays, alis integerrimis flavis apice 

 nigris margineque fulvis: poflicis fubtus puncto argenteo ; this does 

 not agree with, or at leaft exprefs the Infect generally called Palaeno, 

 and the fpecimen in the Linnasan cabinet proves it to be a different 

 fpecies ; the P. Palseno has no yellow fpots on the black margins of 

 the wings, and the fpot in the centre of the anterior pair is fmall 

 and fhaped like a fhuttle ; its native place is unknown. A variety 

 of the pale clouded yellow is found in America, and by miflake is 

 fometimes placed in cabinets as a Britiih fpecies. 



* The wings in the males have a broad black bar on the exterior rrtarg'm; in the female 

 the bar is fpotted.
