PARNASSIUS II— IY. 
dividuals from deep crimson to ochraceous, and frequently are pnpilled with white ; 
_ many individuals also have a black spot near anal angle, and there is very rarely 
found a crimson dot within the black basal spot that occupies the sub-costal inter- 
space; fringes concolored, black at tips of nervules. 
On the under side the markings are repeated, the cellular spots but in part 
dead-black, the crimson spots as above, and where the patch next anal angle is pres- 
ent it is usually pupilled with crimson ; there are also at base four black spots 
usually more or less covered with crimson, but sometimes this last is wanting on one 
or two or even altogether. 
Body small, black, covered thinly with grey-brown hairs on both thorax and 
abdomen above, more thickly beneath, the color there being soiled yellow, often 
with a fulvous tint; legs yellow and black; palpi yellow; antennae white annulated 
with narrow black rings; club black. 
Female. — Expands from 1.7 to 2.5 inches. 
Upper side white, often with a yellow tint, marked generally as in the male, 
and exhibiting as great degree of variation; the crimson spots larger, sometimes 
even four being found in the extra-discal row, the fourth occupying the upper me- 
dian interspace; the spot on inner margin always present and largely pupilled with 
crimson; that near anal angle duplex, usually with crimson pupils; on primaries 
the transparent portions extend half way to cell and quite across the wing, enclos- 
ing a sub-marginal row of white lunules; the hind margin of secondaries more 
or less transparent and presenting a series of black crescents or of patches of 
scales indicating obsolete crescents; there is also frequently a crimson spot at 
base in sub-costal interspace ; on the under side the basal spots vary as in the males, 
from black to grey, and with or without crimson; abdomen furnished with a 
blackish, corneous pouch, flattened and curved down posteriorly, and presenting 
in front a thin, prominent keel; often there is no trace of this pouch. 
Var. Female. — The wings melanized and largely transparent. Found at 
high elevations. 
Yar. Behrii. — Characterised principally by conspicuous submarginal black 
spots on secondaries and orange discal spots, those of costal margin of primaries 
either white or pale orange. In the female the submarginal spots are very conspi- 
cuous and the mesial band on primaries broad; colored spots either orange or red.
