reported damage by Professor Comstock, comprise the following: 
February 5, 1880, at Rock Ledge (Brevard County) and Enterprise, 
Fla., it was destructive to beans, turnip, cabbage, etc. The larva 
was generally known by gardeners as the roller worm. February 21 
larvee were received which were found feeding upon the cowpea 
growing wild along the banks of the St. John’s River at De Land 
Landing, Fla. November 4, 1881, larvee were received from Mr. J. C. 
Neal, Archer, Fla., where they were destructive to Desmodium (Met- 
bomia) canescens. December 2, 1895, we received from Mr. C. K. Bab- 
bitt, Lakeville, Fla., larvee found feeding on bean and cowpea. 
An individual of this species kept at Washington in confinement in 
a moderately heated room (60 to 70° F.) transformed to pupa October 
30, and it was noticed that the pruinosity appeared the next day, 
increasing in intensity for two or three days. The butterfly matured 
December 15, the individual having passed six weeks in the pupal 
condition. In its exit from the chrysalis it left the skin nearly intact. 
Our Divisional records of injury by this species, including the 
HABITS AND LIFE HISTORY. 
A few plants other than those mentioned serve as food for the larva; 
these include different species of Wistaria and Clitoria. Frequently 
larve are so abundant as to nearly destroy otherwise promising fields 
of beans. 
According to the observations of Mr. Quaintance (I. c.) the first 
generation appears in early spring, and successive generations continue 
until cool weather. In the extreme south of Florida, however, devel- 
opment may be nearly continuous throughout the year, as larve have 
been noticed there during the last of December and in January. In 
the heat of summer the life cycle is short, requiring, in some cases, 
only twenty-four days from the deposition of the eggs until the emer- 
gence of the adult. The eggs may hatch in four days, the larve 20 
through their five molts, and in two weeks from the time of hatching 
have been noted to enter the pupal state, the latter stage requiring a 
period of six days. In colder weather in October and November the 
life cycle may require as long as 37 days. It is probable that the 
species hibernates as pupee. 
Eggs are deposited on the lower surface of leaflets of bean in groups 
of from one to six. After feeding a short time the larva prepares a 
retreat by folding over a flap of a leaf. From this shelter the larvee 
crawl out sometimes 6 or 7 inches, and feed upon the surrounding 
foliage. This species does not differ from other butterflies in being 
diurnal in habit, larve and adults moving about freely at all times of 
day.
