(r) Foro-wing with typical yellow patch, also a spoci- 

 men with band as in (a). In the distal area next 

 to the yellow band is a narrow red band as seen 

 in some melpotnene from Guiana. 



{<]) Fore-wing with a red ])atch and yellow costal spot. 

 Hind-wing with a yellow transverse band. This 

 is a very good mimic of the eralo form anacreon, 

 Gr.-Sm., from Bolivia. It is similar to penela- 

 nianda, Stgr. 



(e) Fore-wing similar to (c), but the red band more 

 pronounced and discal patch broken u]) into small 

 spots. Hind-wing with a, yellow band which is 

 distally powdered with red. 



4. Forms of melpomene amandiis, Gi'.-Sm. One specimen 

 approaches nanna, Stich., from S. Brazil, in the yellow median 

 stri})e on fore-wing and the longer yellow band on hind- 

 wing. 



5. //. eralo pln/Uis, Fbr. This form cliicfly rcsembh^s the 

 amandus form above. 



6. A form of eralo phi/Uis which resembles th(> Jiijdara 

 race. This is probably new. 



7. A form of erato similar to the crj/thraca form from Guiana. 

 The hind-wing bears a yellow discal spot, and there is some 

 yellow scaling on the inside edge of the red band in the fore- 

 wing. 



8. A form of erato near ollonis, Iliff. 



9. A form of erato near iellus, Ob., with a yellow discal 

 spot on the hind-wing. 



10. A series of erato tell us, Oli., showing variation in the 

 yellow patch of fore-wing similar to what is seen in specimens 

 of this form from French Guiana. A similar variation occurs 

 in the red form erythraea, Cram. The general tendency, 

 however, in Matto Grosso Heliconius is for the fore-wing 

 patch to have the spots united, whilst in those from French 

 Guiana we find the breaking up of this patch a common 

 variation. In other species from Matto Grosso which have a 

 yellow fore-wing patch, the tendency to contracted spots is 

 still the same.
