columbus. The clayish streak on tlie nnderside of the abdominal fold is more 

 distinct in scrrillc than in cohimbns. 



The clasping organs are individnall}' somewhat variable in both insects. We 

 liave not found any distinction between the two species in these organs. 



The specimens of P. serville from Venezuela are the most interesting. They 

 look exactly like a cross between Colombian serville and Colombian colnmbus. 

 However, as P. columbus is not known from Venezuela, there can be no question of 

 hybridisation, to which describers so often resort in order to get easily over 

 difficulties. 



Godart did not know from which locality the type came. Hitherto Colombian 

 specimens have usually been regarded as typical. This is apparently erroneous; 

 though Godart's description, being taken from a single specimen, — probably lost : 

 Boisduval, I.e., says that he had seen the type, but does not add anything to Godart's 

 description, — is naturally not so precise as to enable us to say with absolute certainty 

 from which country the type came. However, there is one point in his description 

 which bears on this question. The abdomen is said to be like that of P. dolicaon. 

 Now, in P. dolicaon the pale stripes of the abdomen are always broad. This is the 

 case only in the southern subspecies of P. serville. Therefore we have to accept as 

 typical the southern form of serville, not the northern. The Colomliian insects were 

 not yet known at Godart's time ; all the very common Colombian forms have been 

 described later. The South American species of the Enc. Meth. were from Brazil, 

 Surinam (and Guyane), and from Peru. We may therefore safely assume that the 

 sjiecimen of P. serville also came from Peru. The " Peru " of that time, however, 

 included what became Bolivia in 1825. Therefore it is impossible to say whether 

 the Peruvian specimens came from what is now termed Peru, or whether they came 

 from some part of the present-day Bolivia.
