MR. DOUBLEDAY’S NOTES ON THE HABITS OF THE NORTH AMERICAN 
SPECIES OF PAPILIO: CONCLUDED. 
Papilio Turnus is very widely spread, and seems to vary much 
from the effects of climate. The extreme northern ones (as New- 
foundland specimens) are paler, (sometimes, Mr. Gosse tells me, with 
the ground nearly white,) and have the bands less clearly defined ; 
the black being a good deal suffused (especially in the ¢) over the 
yellow. The southern species generally expand from 3 to 1 inch 
more than the northern ones, and have the colours brighter, the 
black being more velvety and better defined. 
I found Turnus common at Trenton Falls, N. Y., in June, fre- 
quenting the lilacs in the gardens, and then easily captured ; indeed 
I have often taken them off the flowers with my fingers. When 
flying its appearance is beautiful, from its sailing along with its 
wings expanded. Then it is hard to take. In Ohio it is common, 
and not rare anywhere in the southern states; being found alike in 
the low country near the sea and on the loftiest of the wooded 
Alleghanies (say 3000 to 4000 feet elevation). It frequents in the 
south, Cnicus horridulus, Anona grandiflora, Cephalanthus occiden- 
talis, &c. .In crossing the mountains of N. Carolina and Tennessee 
we saw in plenty in the wet patches of the roads, by the sides 
of the numerous water-courses, &c. for it loves to sit in the mud, 
and in Ohio, where the roads are none of the best, it was equally 
abundant. 
P. Glaucus is very rare in general, and almost confined to the 
southern states. I never saw it but two or three times. It some- 
times, in early spring, comes to the plane-tree blossoms, but is 
mostly seen soaring over the high underwood. Its flight is very 
rapid. R. Foster took it in Ohio. I have specimens taken in 
Delaware (its northern limit!), and it occurred occasionally in 
E. Florida. 
P. Troilus in its habits resembles Philenor. I have often seen
