species was wrongly identified by Staudinger in " Iris," vii, 

 ]). 225, where he refers to the most splendid of the Dynamine 

 species perpetua, going on to describe a black insect with 

 steel-blue bands on the fore-wing and on the hind-wing. 

 Perpetua, described by Bates in the " Journal of Entomology '.' 

 (1865), p. 326, is a green species and has nothing to do with 

 the present insect. 



He further exhibited from his own collection an association 

 of Heliconine forms from Para, all taken in the months 

 July and August 1917. There were seventeen H. melpomene 

 thelxiope, mostly fairly typical, nine //. erato amazona and 

 three Eueides tales pytkagoras. Although Heliconius melpomene 

 thelxiope here appeared to act as the model it was not really 

 so, as H. erato amazona was certainly the commoner butterfly 

 of the two at Para, while the Eueides always was third in point 

 of numbers, and in any case reinforced the amazona owing 

 to the manner of the streaking. It was probably true that 

 //. erato amazona appeared a little earlier than H. thelxiope, 

 and thus advertised the colour scheme a little in advance, 

 so that it was possible that at the end of the time of appear- 

 ance thelxiope might sustain few attacks, although be present 

 in some numbers. It was obvious from the specimens that 

 amazona, had been out some time, as all the specimens appeared 

 orange and not rosy red as in fresh specimens. 



A second small association was a well-known one in point 

 of species, but little or perhaps unknown as to locality. The 

 species were H. melpomene nanna and 11. erato phyllis and 

 the locality Pernambuco. There were four specimens of the 

 former and two only of the latter; here again the seeming 



vein 3 to inner. Hind-wing deep velvety black with a large oval patch 

 lying along outer margin between vein 4 and tornus. 



Underside of fore-wing blackish with the greater part of the cell 

 ochreous except for two Mack marks edged above with blue. Three 

 white spots forming an oblique apical band, a white spot within the 

 cell and a dirty white spot near tornus. A double blue subterminal 

 as far as vein '.I. Underside of hind-wing dirty whitish with three 

 nearly parallel oblique brown bands, the two outer ones united above 

 tin- cell by an interrupted blue band. Two eye spots, the upper, tin' 

 larger, surrounded with an ochre yellow ring and placed on a purplish 

 patch. A regular ochre narrow submarginal band narrowly edged 

 with blue. The underside is very similar to Dynamine onias, underside 

 white, the upperside strongly suggests Eunica flora.
