appeared to be markedly gregarious and therefore unlikely to 

 adopt a highly specialised form of Protective Resemblance. 



Exotic Rhopalocera. — Mr. G. Talbot exhibited the 

 following species on behalf of Mr. J. J. Joicey : — 



Dasyopthalma rusina, Godt. A melanic aberration of the 

 female in which the bands are only present as vestiges. 



Papilio ridleyanus, White. Dark aberrations of the male 

 in which the red spots of the fore-wing are obscured by dark 

 scaling. In one specimen most of the scales on these spots 

 are black with some red ones intermixed. In this specimen 

 the hind-wing is also very dark. These aberrations seem 

 to correspond to the female forms of Acraea egiiia and 

 zeles, and of Pseud acraea triHteni, with which the Pajiilio is 

 associated. This dark aberration has received the name of 

 funiata, Niep. 



Papilio phidias, Ob. A ^ example of this very rare and 

 extraordinary species from Tonkin. This species forms a 

 link with the tailed antiphalcs and aristeus forms and the 

 tailless macareus forms. It enters into the mimetic group 

 with Danaine pattern. Tliere are 3 r^^^ in the Coll. of Oberthiir, 

 2 ^o in the Paris Museum, and 2 oc^ in the Joicey Coll. The 

 latter are from Tonkin, and the others from Annam. The 

 V is unknown. 



Heliconius from Matto Grosso : — 



1. A distinct form of eletmhis, Nold., probably undescribed 

 and connecting this form with hari, Ob. The pattern of both 

 wings is very similar to hari, but there are no apical spots on 

 the fore-wing. In this it differs from lumatuniari, Kaye. 

 The two forms of hari occur in the Guianas, whilst elcvatus 

 occurs in Bolivia, Upper Amazon and Peru. 



2. A species of melpomene thelxiope from Para, showing its 

 great likeness to the elevalus form. 



3. Form of iiielpo))iene peiielopc, Stgr. There are five forms. 



((/) Fore-wing with much-reduced yellow band and 

 no spot in the cell. Very similar to a specimen 

 of thelxiope from the Lower Amazons. 



(6) Fore-wing with yellow patch. Tlie typical form, 

 occuring also in Bolivia.
