Nortu American ButrerFiies.—Mr. E. B. Asusy ex- 
hibited a number of Nearctic Butterflies, including several 
belonging to genera widely distributed in the Palaearctic 
Region. ; 
HELICONIUS ANDERIDA.—Mr. W. J. Kaye exhibited a very 
large series of specimens of Heliconius anderida ranging into 
a number of forms which tended to become fairly definite 
subspecies in different geographical regions. In Panama in 
the canal zone the following named forms occurred and were so 
intergraded that they could only be looked on as aberrations of 
one variable species; such were, clara, Fab., melicerta, Bates, 
albucilla, Bates, albipunctata, Riff., zulecka, Hew. In Costa 
Rica the zuleika form occurred almost exclusively, and only 
very rarely did forms occur that were referable to albipunctata, 
Riff., but specimens transitional to this latter form were less 
rare. In N.W. Venezuela, near Porto Cabello, a further 
development occurred out of the anderida and clara forms, in 
which a submarginal row of paired yellow spots appeared on 
the hind-wing, the fore-wing being normal clara. This form 
had apparently no name and it was proposed to call it estebana.* 
A further set of specimens was from Colombia from the so- 
called Bogota district, but which really referred to a much 
lower elevation. ‘These specimens were the usual clara form 
and were more or less constant. A single specimen from the 
Rio Dagua in W. Colombia was shown of the holcophora form. 
It was thus shown that in Panama the species was altogether 
unstable, but both northwards, eastwards and still further 
eastwards definite races were developed. The series was 
* HELICONIUS ANDERIDA ESTEBANA, 0. sub-sp. 
g. Fore-wing like H. anderida clara, but with less yellow within the 
cell and the large black blotch extended towards the base as a wedge. 
The black spot on the yellow patch between veins 2, 3 large and nearly 
touching the edge of the cell. Hind-wing with broad black marginal 
band containing four pairs of elongate yellow spots. ¢. Fore-wing 
as in ¢, but with a great extension of black beneath vein 2. Hind-wing 
with the black marginal band becoming broken at vein 4, and with the 
innermost pair of yellow spots barely visible. A single elongate yellow 
mark above vein 7.
