SUPPLEMENTARY NOTES. 
Papilio Zolicaon. —In 1883, I raised many larvae from eggs sent me by 
Mr. W. G. Wright, of San Bernardino, California, and obtained descriptions, as 
well as a series of drawings, of all the larval stages. It was my intention 
to give an additional Plate illustrating these stages and the corresponding 
ones of Asterias and Machaon ; but circumstances have compelled me to post¬ 
pone the Plate. If I go on with a third Volume this species will receive early 
attention. 
In the text to Zolicaon I said: “ Zolicaon belongs to the Machaon group.” 
Further examination of the imago shows that the two species are not members 
of the same group, and this is sustained by the comparison of the larval stages. 
Zolicaon is nearer Asterias. So far as concerns the butterflies I have treated 
of these species and their relationship at length in “ Papilio,” vol. iii., p. 45, et scq, 
1883. 
Papilio Okegonia. — In the descriptive text I said: “ The anal spot small, 
. . . with a rounded black spot in the middle , and which is connected with the 
narrow black edge of the margin.” It should properly have read, “ with a stripe 
or club-shaped spot in the middle,” etc. In the paper above referred to, in “ Pa¬ 
pilio,” vol. iii., the peculiarities of the anal spots in Oregonia, Machaon, Zolicaon, 
and Asterias are illustrated by figures, and in the text the relationship of all 
these and other allied species is considered. As regards Oregonia, I come to 
this conclusion : “ Oregonia belongs to the Machaon group, and (perhaps with 
some other species) forms a sub-group of equal rank at least with the sub-group 
to which the species Machaon belongs. It certainly cannot have been derived 
from the species Machaon .” I have a colored drawing of the mature larva of 
Oregonia, made by Mr. ft. H. Stretch, and there is very little resemblance be¬ 
tween it and the mature larva of Machaon. 
Papilio Datjnus. — Mr. B. Neumoegen received, in 1881, two blown skins of 
the mature larva of this species and three living chrysalids. One of the latter 
was given me, and after a drawing was made of it I put it in alcohol. The
