INSECTS. INJURIOUS TO THE PINE. . Tek 
are dark rust color, and the lighter light gray. It belongs to the family 
Tortricid, the larve of which are usually leaf-rollers. 
From what we have been able to learn, we conclude that there are 
two broods of this insect in a- year, and that the second brood hiber- 
nates in the larva state. May 25, burrows were found from which the 
moths had already issued. In the breeding cages at Washington the 
moths issued until June 20, when the last oue made its exit. August 
23, larvee were received which were nearly full grown, and were pre- 
sumably of the second brood. In the following January nearly all the 
larve found were only about half grown; none were more than two- 
thirds grown. 
At the approach of winter the larve prepare their burrows for hiber- 
nation by lining them with delicate layers of white silk, which often 
form tubes closed at the lower end. The larva remains through the 
winter withits head at the posterior end of the mine. Before the change 
to the chrysalis state, however, this position is reversed and the head is 
towards the opening. 
Wherever a twig is pierced and bored by one of these larve the leaves 
begin to turn yellowish and the twig often dies. In many cases, how- 
ever, more than one of the larve are to be found in a single twig, and 
this of course more certainly insurvs its death. It seems probable that 
the principal damage done is the disfiguring of the shape of the tree by 
the destruction of terminal shoots. 
It is probably this caterpillar which in the summers of 1873~74 proved 
very destructive to the pitch pine bushes in and about Brunswick, 
Me., causing the upper part of the bush to turn yellow and die. 
The moths bred from the burrows were submitted to Professor Fer, 
nald, who decided that they represented a new species, probably belong- 
ing to the genus Retinia. This species he describes in the Canadian 
Entomologist, vol. xi, p. 157. We quote Professor Fernald’s descrip- 
tion of the moth, and append descriptions of the larva and pupa so that 
the insect may be recognized in whatever stage it is found. 
The moth.—Heail in front, basal joints of antenne, and palpi white; 
last joint of palpi and a few scales upon the outside of the middle joint 
dark gray. lHyes black, vertex light sulphur-yellow to straw-yellow. 
antenne dark brown, annulated with whitish. Thorax above white, 
with a few scattered gray scales; beneath silvery white. Abdomen 
above light brown, with a silvery luster; lighter at the end of each seg- 
ment; beneath lighter ; last segment in the females darker brown above 
and beneath, and without the silvery luster. Anal tuft in the males 
light straw color. Fore and middle legs light brown, femora and tibize 
of hind legs white, tarsi of all the legs brown, ringed with white. Fore 
wings ferruginous brown, the extreme costal edge from base to near the 
apex dark brown. A number of small white spots rest upon the costa, 
four hairs beyond the middle, from all of which stripes composed of
