68 HABITS OF AMERICAN PAPILIONES. 
produced into a very short tail. On the upper side the disk of the 
wings is of a fine raven blue-black ; the apical margin of the fore wings 
marked with small whitish spots between the longitudinal veins ; 
the hind wings have whitish marginal scallops, and a row of six erim- 
son-pink submarginal lunules, and an irregularly squarish spot of 
the same colour within the anal angle. 
The under side (represented in fig. 3) is similar to the upper, 
except that the disk is not so intensely raven black, and the red 
lunules of the hind wings are rather smaller. The body is black, 
with the palpi and sides of the head, thorax, and abdomen 
crimson pink. 
The orchidaceous plant represented in the plate is the Maxillaria 
tenuifolia of Lindley (Bot. Reg. v. 25, pl. 8), a native of Mexico, 
recently mtroduced into this country. 
MR. DOUBLEDAY’S NOTES ON THE HABITS OF THE NORTH 
AMERICAN SPECIES OF PAPILIO. 
(Continued from page 62.) 
P. Calchas is quite a southern species. I do not know its northern 
limit precisely, but am not aware of its occurring farther north than 
N. Carolina; Cramer I think says Virginia; but his localities are not 
to be depended on, any more than Boisduval, who mistakes states as 
large as England for towns. I only saw it in E. Florida, where I 
found the larva on the Red Bay, Laurus Carolinensis. The perfect 
insect I saw first early in February, when I captured a worn speci- 
men on the flowers of Gelsemium sempervirens. This had of course 
hybernated. I found it in profusion at St. John’s Bluff, chiefly in 
an open spot near the river, and in old cotton fields, where it fre- 
quented the flowers of Cnicus horridulus, and was then very easy 
to take. Sometimes it sails up and down the pathways in the 
woods, its flight then is easy and almost majestic. 
P. Philenor. See Harris for its northern limit. I know of its 
occurrence in different localities from N. York to E. Florida. It 
there (E. F.) frequented the flowers of Annona grandiflora. It is 
fond of alighting in the mud, like Turnus &e. My western specimens 
are infinitely finer both in size and colour than any I have seen from 
the Atlantic states, be they northern or southern. Flight not very 
powerful, generally low.
