seema to prevail in the Life-history of Soiapteron pint Kellicott, a species 
described by its author in the Can. Entom., 1881. (See p. 726.) 
Mnilt.— Male. Forewinga with the margins all black, the costal edge rather broad. 
Hind wings, with the costal and base of the abdominal margin, pale yellow. Beneath. 
the {brewings have the margina lemon yellow, as far as the diacal mark, beyond 
this, black. Hmd wings as on the upper side. Head and antenna) jet black. Palpi 
lemon yellow, black at the sides. Fore femora, orbits of eyes and base of wings 
beneath lemon yellow. Middle and hind femora black. Tibia Lemon yellow, bor- 
dered with black. Thorax with collar, tegnhe, the two narrow dorsal lines, and a 
basal line lemon yellow. Abdomen, with all the segments except the fourth, narrowly 
bordered with rich lemon yellow. Caudal tuft yellow below, blackish above. 
Female similar, but a little larger and more robust, the abdominal band hroader and 
better denned. Expanse of wiugs, male, 24 mm ; female, 30 mm . (H.Edwards.) 
68. The pine BLIGHT. 
Coccus pinicorticis Fitch. 
Order Hemiptera ; family Coccid.e. 
Externally, upon the smooth bark of young trees, patches of white flocculent down- 
like matter, covering exceedingly minute lice, invisible to the naked eye. (Trans. 
N. Y. State Ag. Sjc, 1854. p. 871. Compare also an article by Dr. H. Shinier in 
Trans. Amer. Soc, ii, pp. 383-385.) 
AFFECTING THE TWIGS. 
69. The white-pine weevil. 
Pissodes strobi Peck. 
(Larva, Plate xxm ; Fig. 5 ; pupa, fig. 6; also Plate xxvu.) 
Order Coleoptera ; family Curculioxid.e. 
In May, depositing numerous eggs in the bark of the topmost shoot of young tiees, 
the larva} from which mine in the wood and pith, causing the shoot to wither and die, 
thereby occasioning a crook or fork in the body of the tree at this point ; an oblong 
oval and rather narrow weevil about a quarter of an inch long, of a dull dark chest- 
nut-brown color, with two dots on the thorax ; the scutel and a short irregular band 
back of the middle of the wing-covers milk white, the wiug-covers also variegated 
with a few patches of tawny yellow. 
For many years past our attention has been drawn to the deformities 
produced iu forest trees by this beetle, as well as the injury it commits 
in plantations and to ornamental trees on lawns and about houses. 
Dr. Fitch has already outlined the natural history of the insect in his 
fourth report. We have not yet been able to detect the beetle in the 
act of egg-laying. Fitch says that the weevil deposits her eggs iu the 
bark of the topmost shoot of the tree, dropping one in a place at irreg- 
ular intervals through its whole length. " The worm which hatches 
from these eggs eats its way inwards and obliquely downwards till it 
reaches the pith, in which it mines its burrow onwards a short distance 
farther, the whole length of its track being only about half an inch.
