PAPILIO VII. 
} ellou on the black ground; in the cell the yellow spots are repeated and en- 
laiged ; the base of cell is dull or luteous yellow, and sends out four long rays 
which nearly reach the middle; secondaries have all the nervures black, those 
about cell and the basal portion of the costal nervure being heavily edged with 
black ; the lunules much enlarged and changed into subquadrate spots, occupy¬ 
ing fully half the border, the black ground above them being heavily dusted 
with yellow and blue; the fulvous of anal spot is changed to orange-yellow, and 
the two yellow discal spots against cell sometimes have their outer ends vellow- 
tinted. 
Body black on upper side, elsewhere yellow, but about the thorax fulvous- 
tinted; a black stripe from the head reaches the insertion of the wings; beneath 
abdomen two black stripes, and one on lower part of either side, from wings to 
last segment; legs black; palpi yellow, or with a fulvous tint; frontal hairs 
black, but next the eyes yellow : antennae and club black. 
Female. — Expands 4.25 inch. 
Similar to the male, the yellow paler; the blue clusters larger and more dis¬ 
tinct. 
I described this species as a variety of Hippocrates in 1876,' from a female 
taken by Mr. Henry Edwards, at the Dalles, Columbia River. Mr. H. K. Morri¬ 
son took several examples of both sexes in Washington Territory, near Olympia, 
in 1879, and from some of these the figures on the Plate are drawn. In all 
I have examined, 2 J 3?. I am satisfied they are not Hippocrates , but a dis¬ 
tinct species, of same sub-group, and near to Zolicaon. Felder, Verhand. Zodl. 
Bot., Geschied xiv. pp. 314, 362, 1864, describes Hippocrates as much larger 
than Machaon , the yellow area narrower, the wings narrower and more pro¬ 
duced; the hind wings also shorter on the costa, more produced posteriorly; the 
tails longer, the anal spot more obscurely colored, and joined abruptly to the 
blue lunule; the black border of the hind wings on the under side much broader, 
the blue spots more distinct, and placed almost in the middle of the black ground' 
the outer ones accompanied by few yellow atoms, and the cells of both wings 
longer. 
To this may be added that the black marginal border of hind wings on upper 
side is considerably broader than Machaon, if I may judge by 3 of Hippoc¬ 
rates, from Japan, before me. In all these this border is nearly straight-edged 
on the inner side, and almost touches the cell in two examples, and quite 
touches it in the other; and the tails, beside being longer, are not tapering as in 
Machaon, but are of nearly even width almost to the extremity, where they be¬ 
come broader, or sub-spatulate. On the under side of primaries the black cel-
