760 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION 
' 
fcheil work that tin* LophfTMt was ran- the next summer (1869). If this wholesale 
destruction of tin- larva- had not occurred, there would bare been acres of young 
pines destroyed. 
I did not meet with tin- red crossbill until January, when I met a flock at Sand- 
wich : in February I met a flock here (Eastham). Neither of these hirds are com- 
mon visitors to the Cape. I have not known of any visiting OS the past winter. I 
DCYer mel with one until l-ti"\ bnt residents of Eastham informed me that tin- white- 
was with tlirm in the fall of 1867. An old lady in East Falmouth 
informed me that a number of yean ago tiny visited her orchard and damaged her 
apples by ontting them off to get tin- seeds. 
~J. THH LTDA SAW-FLY. 
Infesting the Austrian pine, tying the needles together with a silken web filled 
with castings, forming a mass abont G inches in diameter, with the needles of the 
pine scattered through the mass, the leaves being separated by the false-caterpillars 
from the branch. 
We have noticed this false-caterpillar on bnt a single occasion, and 
then failed to rear the worms to the winged state. The following ac- 
count is taken from our article entitled 4 ' Injurious Insects, Xew and 
Little Known," in the Keport of the Massachusetts Board of Agricult- 
ure for 1870: 
Late in September of 1669, Dr. William Mack, of Salem, Mass., brought into the 
museum of the Peabody Academy of Science some singular false-caterpillars which 
had assembled on a single brauch of an Austrian pine, on his place, and had tied the 
needles together with a fine silken web filled with castings, forming a mass of cast- 
ings about 6 inches in diameter, with the needles of the pine among them, the 
< being separated by the larva? from the branch. 
The larva is that of a species of Lyda, and while doing little injury to the tree, so 
far as known, yet merits a short description. Dr. Ratsbnrg figures a similar species 
in his work on forest insects, and states that the Lyda 
campesti'is of Europe, to which our species seems closely 
allied, is sporadic in its attacks on the pine and never 
proves very destructive. 
The larva. — The body is cylindrical, a little flattened, 
and thickest in the middle, with small thoracic slen- 
der legs, which are not used much in walking, the 
larva wriggling along when placed on a smooth surface. 
The bead is pale reddish with a black spot between the 
antenna': the prothorax is black above and the body 
reddish olive-green, with a rather broad purplish line 
along the middle of tin- hack. There are no abdominal 
legs, and the end of the body is somewhat flattened, 
with a black round spot on each side of the auall 
plate : beneath is a broad transverse incision. Below, 
and arising from each side, is a long, corneous, three- 
jointed, slender out-stretched appendage of the size 
and form of the antenna-. The under side of the 
body is mottled with greenish and reddish as above, 
with a reddish median line. On the side of the thorax 
arc two rows of dots, and two rows along the middle on the ventral side of the 
three thoracic wings.
