THE EOSE SLUG-CATERPILLAR. 
(Euclea indetermina Boisd.) 
INTRODUCTION. 
It is only within comparatively recent years that the slug-like 
caterpillar, Euclea indetermina Boisd., has been known to injure the 
rose. In August, 1905, the Bureau of Entomology received two 
reports of attack to the foliage of rosebushes by this species. The 
insect has, however, been previously observed to have this food habit. 
August 15, 1905, Dr. A. D. Hopkins furnished specimens of the 
larva from Kanawha Station, T\ r . Va., stating that a dozen or more 
individuals could be found feeding on the leaves of a single rosebush. 
By August 20 the specimens received had transformed to pupse. 
During the last week of August the same species, accompanied by 
specimens of both the penultimate and last stages, was received from 
Mr. S. D. Nixon, with report that it was injuring roses at Balti- 
more, Md. 
The rose slug-caterpillar has been figured and described in its 
various stages, but is not a common species and, therefore, not well 
known. It is, however, strongly and attractively marked and very 
interesting in its transformations, resembling in some particulars the 
more common and related saddle-back caterpillar ( [Empretia] Sibine 
stiniidea Clem.). The accompanying illustration (fig. 1), notes, and 
brief descriptions have been brought together as of interest to rose 
growers and also to nurserymen, for the caterpillars also attack 
young trees and shrubs. It is in the last two stages of its larval 
existence that this species attracts most attention. The moth which 
it produces is less often seen. 
THE MOTH. 
In its adult stage this insect is nearly as attractive as the larva. 
Its coloration is unusual in the boreal American fauna. The general 
color is pale cinnamon brown ; the forewings are darker and crossed 
diagonally by a green band, which occupies more than half the 
wing, leaving a wide border of darker brown and an inner or basal 
area of the same color and of the form shown in figure 1, a. The 
hind wings and the underside of the wings are nearly uniform pale 
brown, as is also the body, except on the edges of the wings and 
the tip of the abdomen. The thorax is like green plush. The wing
