REMEDIES. 
The same remedies advised against the American rose slug are em- 
ployed against the present species, with the exception of fall cultiva- 
tion, which is practically useless when appled to it, owing to the 
fact that the cocoons are formed, upon the plants on the surface of 
the ground and not buried in the earth as with the preceding species. 
Since there are more than one generation of this slug, sprinkling 
with water and spraying with poisons must be repeated several times 
in order to produce the desired results; in short, as often as the 
insects reappear upon the plants, from April to October, according to 
locality. 
THE COILED ROSE SLUG. 
(Hmphytus cinctus 1.%) 
The third of the rose slugs under consideration, the coiled rose 
slug, is a comparatively recent importation. As with the two pre- 
ceding species, it first attracted attention near Boston, Mass., but 
not until the year 1887.2 It is probable, however, as in the case of 
most European insects introduced into this country, that its importa- 
tion was accomplished at a considerably earlier date. Reasoning 
from analogy, this insect might have been brought from the mother 
country on potted roses ten or twenty.years earlier than the date 
specified, as that length of time is sometimes necessary for a foreign 
insect to become permanently established so as to attract attention 
by its injuries. 
DESCRIPTION AND DISTRIBUTION. 
From the two preceding species this insect may be readily sepa- 
rated on account of its larger size in the adult stage (fig. 5,a). It has 
nearly transparent wings, and a wide band which crosses its shining 
black abdomen near the middle. The body is comparatively slender, 
and the head longer than in the other two species. The wing expanse 
is about five-eighths of an inch and the length of the body about three- 
eighths of an inch. 
The larva when mature is about three-fourths of an inch long and 
differs notably from the other two species here considered in being 
perfectly smooth. It is cylindrical and tapers very shghtly toward 
the posterior extremity. The color is metallic green above, orna- 
mented with small white dots, and the lower surface, including the 
legs, is grayish white. The head (fig. 5, ¢) is yellowish orange, with 
a dark brownish-black stripe down the middle. The eyes are black. 
@Emphytus cinctipes Nort. is recognized as a synonym.
