NOTES ON DIVISIONAL RECORDS. 
Our Divisional records of injury by this species, including the 
reported damage by Professor Comstock, comprise the following: 
February 5, 1880, at Rock Ledge (Brevard Count} 7 ) and Enterprise, 
Fla., it was destructive to beans, turnip, cabbage, etc. The larva 
was generally known by gardeners as the roller worm. February 21 
larvae 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 1, 1881, larvae were received from Mr. J. C. 
Neal, Archer, Fla., where they were destructive to Desmodimn (Mei- 
homia) canescens. December 2, 1895, we received from Mr. C. K. Bab- 
bitt, Lakeville, Fla. , larvae 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. 
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 
larvae are so abundant as to nearly destro} 7 otherwise promising fields 
of beans. 
According to the observations of Mr. Quaintance (1. 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 } 7 ear, as larva? 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 ma} 7 hatch in four days, the larvae go 
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 ma} r require as long as 37 days. It is probable that the 
species hibernates as pupae. 
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 larvae 
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, larvae and adults moving about freely at all times of 
day.
