a collection of Heliconine forms from French Guiana. 431 



with conspicuous white streaks behind. Palpi with 1st and 2nd 

 joints conspicuously white. Third joint black. 

 Exp. 64-76 mm. 



Habitat. French Guiana, St. Jean. 



This remarkable species is more Heliconiform than any 

 other known species. The antennae are decidedly longer 

 than is usual in Eueides species. The brand on the inner 

 margin of the fore-wing on the underside is shiny and 

 smooth-scaled as in Group I of Heliconius. But the streak- 

 ing on the underside of the hind- wing is like Group II. The 

 neuration of Heliconius and Eueides varies on parallel 

 lines, and no one character seems to be constant. In 

 Heliconius vein 5 is usually nearer 6 than 4, while in Eueides 

 it is usually nearer 4 than 6. In E. egeriformis it is nearer 

 6 than 4, and thus like Heliconius. But the general 

 appearance is certainly Eueides, while the mix up of 

 Heliconius characters of sections I and II makes it certain 

 that it is not a Heliconius.
