SUPPLEMENTARY NOTES. 
Papilio Ajax. — The chrysalids mentioned in the text as haying passed over 
the winter of 1871 — 2, commenced yielding imagos in February and continued till 
12th April, with the following results: 
From 1st and 2nd brood Walshii — 2?, 2?, Telamonides, 1 $, Marcettus. 
From Walshii of 23rd May — 7 $, 2?, Telamonides , 1?, Marcellus. 
From Telamonides of 27th May — 7 $, 3?, Telamonides. 
From Telamonides of 28th May — 3?, 3$, Telamonides. 
From Marcellus of 1st and 4th June — 13c?, 23?, Telamonides, 3 ?, Marcellus. 
From Marcellus of 29th July — 14?, 13 ?, Telamonides. 
Total 46 $, 46 ?, Telamonides, 1 $, 4 ?, Marcellus, and no Walshii. 
Nevertheless, between the 11th of April and 1st of May, Walshii was exceed- 
ingly abundant on the wing, and up to 29th of April, Mr. Mead, who was with me, 
had taken 63 specimens, while he had taken or seen but one Telamonides. Soon 
after 1st of May, the latter variety appeared in small numbers, too early evidently 
to have sprung from Walshii of this year. By 25th of May, Telamonides suddenly 
appeared in such force as to make it certain that they had now begun to come from 
the larvae produced from eggs of Walshii. But why not one of nearly one hun- 
dred chrysalids, from so many broods of 1871, and of all the varieties, should yield 
Walshii, while out of doors this variety was so abundant and for weeks the only 
one flying, is surprising. The same thing had happened with chrysalids carried 
over the winter of 1868 — 9, when of 32 imagos but one was Walshii. As the chrys- 
alids were kept in the house and the imagos emerged prematurely, some of them 
by several weeks, owing to the warm temperature, it is possible that the artificial 
acceleration may have had to do with producing the later varieties at the ex- 
pense of the earlier, or Walshii. 
Neophasia Mexapia. — The figure given on the plate as the female is erro- 
neous. Until quite lately the two sexes were supposed to be similar, but specimens 
taken on San Juan Island by Dr. Bremner, show a wide difference. 
Female. — Size of male. Color yellowish or soiled white ; the black apical 
patch enlarged, the five enclosed spots being yellowish; costal stripe as in male; 
secondaries have a broad black border enclosing on the margin a series of separated, 
rounded yellowish spots that occupy the interspaces from outer angle to lower
