250 GRAPHOLITHIDS. 
thoracic and anal shields very dark, polished brown. There 
are ten lighter brown protuberances on each segment, 
from each of: which arises one pale hair. On the upper 
surface of the ninth segment is seen the double undeveloped 
reproductive organ of a light brown color. The legs are 
dark brown and the prolegs yellowish-brown. About the 
first of June the larva is from ten to twelve millimeters in 
length, and the body has changed to a cinnamon-rufous 
color. From the middle to the last of June it curls or draws 
together several leaves which it lines with silk, and in which 
it transforms to a pupa. 
“The pupa is seven millimeters long, brownish-yellow, 
tapering from the head to the posterior end, with the wing- 
cases dark-brown. There are two rows of dark-brown 
spines pointing backwards, across each abdominal segment. 
The spiracles and anal segment are dark-brown. It remains 
in the pupa stage about two weeks and then the moth 
emerges. 
‘For some years past, I have observed the habits of this 
insect, and have been able to carry it through its transfor- 
mations. The moths emerge between the last of June and 
the middle of July, though belated specimens are sometimes 
taken on the wing as late as the middle of August, and one 
was taken at this place August 25th, 1889. 
“The fore-wings expand about three-fifths of an inch. 
The head, thorax, and basal third of the fore-wings, and also 
the outer edge and fringe are dark ash-gray, the middle of 
the fore-wings is cream-white, marked more or less with 
costal streaks. Just before the anal angle are two short, 
horizontal, black dashes followed by a vertical streak of 
lead-blue, and there are three or four similar black dashes 
before the apex, also followed by a streak of lead-blue. 
“The hind-wings above and below the abdomen are 
ashy-gray. The underside of the fore-wings is darker, and 
has a series of light, costal streaks on the outer part. 
“To destroy these caterpillars, it is desirable to gather
