PAPH1A. 
Tlie genus Paphia contains a number of species which inhabit the tropical 
regions of America, from Mexico to Brazil, but Glycerium is the only one whose 
range is known to extend into the United States. It is found upon the prairies 
of Illinois, Missouri, Kansas and Texas. 
I have never seen it on the wing, but am indebted principally to Dr. L. K. 
Hayhurst, of Sedalia, Mo., for copious notes upon its habits and for descriptions, 
as also for the drawing of the food-plant, larva and chrysalis represented on the 
plate. 
Dr. Hayhurst says : “ The larvae feed on the plant commonly known as Wild 
Sage, Croton capitatum, as many as a dozen individuals being sometimes found on 
one low bush. 
“ The leaf of this plant is ovate-lanceolate, about two inches long and three 
fourths inch broad. On the mid-rib the larva extends itself, its head toward base 
of leaf and attaches a thread to the edge at about one third the distance from base 
to apex. By a tension on the thread it draws this edge partly towards the other 
and there fastens it, being assisted by the natural tendency of the leaf to curl in- 
ward. The operation is repeated until the edges meet, when the larva proceeds to 
join them firmly, almost to the apex, leaving a small opening through which to 
eject its castings. 
“ During the heat of the day, it remains concealed, but towards evening comes 
out to feed, though sometimes it feeds upon its own house, eating the leaf half 
way down from base to point, then abandoning it and rolling up a new one. 
“ When placed in a cool, shaded room, the larvae seldom rolled up leaves, but 
fed at random over the plant, and when at rest simply lay extended on the leaves. 
Many, though not all, of the rolled leaves that I cut open, were completely lined 
with a closely woven coating of strong white silk. 
“In a glass breeding cage, the larva will travel over the sides as readily as 
over a rough surface. This it does by spinning a sort of rope-ladder in advance, 
describing segments of circles by the motion of its head from one side to the other. 
“ When ready to transform it spins a button of white silk on the under side 
of a leaf or branch, and, fastening the anal legs therein, doubles upon itself until 
the extremities meet. In this position it remains about twenty four hours when it 
suddenly throws off its larval skin and becomes a chrysalis. Some of my chrysa- 
lids were eighteen and twenty days before the butterfly emerged. 
“ The flight of the butterfly is exceedingly rapid, with a dry, whistling sound. 
Although easily alarmed it seldom leaves a favorite locality, but continues to fly 
about until danger has passed. It is curious as the Vanessas, and I have several 
times taken it by standing motionless, when after numberless rapid circlings 
and dashes about me, it would suddenly alight on the ring of my net.
