924 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
PLATE vii. 
The original drawings both plain aud colored, 
were made by Mr. J. Henry Blake, of Cambridge. 
Fig. 1. Rttinia frustrana. The moth, enlarged 
three diameters. 
2. Side view of chrysalis, enlarged three di- 
Mnetere. 2a. One of the abdominal joints 
enlarged nine diameters, to show the 
rowa of spines and ridges. 
3. Front view of chr\ salis, enlarged three di- 
ameters. ;j«. The terminal joints of the 
abdomen, enlarged nine diameters, to 
show the arrangement of spines and 
hairs at the tip of the body. 
4. Full-grown caterpillar, enlarged four di 
ametera. 
5. Terminal shoot of the pine in an unin- 
jured, natural condition. 
6. Terminal shoot which has been attacked 
by the insect when the apical leaves 
were only partly grown ; away from the 
tip the needles have nearly or quite at- 
tained their full growth before the 
mining operations of the caterpillar had 
sapped their supply of nourishment. 
7. Terminal shoots in a healthy condition, 
stripped of its needles, to contrast 
with fig. 9. 
8. An infested shoot cut open to lay bare the 
mine of the caterpillarin its latest stage, 
the refuse which nearly fills it has been 
removed. The length of the terminal 
needles shows this shoot to have been 
well advanced in its growth before it 
was attacked. 
9. A shoot similar to that represented in 
fig. 7, but which has been distorted by 
the attacks of the insect.

have been infested by bark-boring bee- 
tles and other borers, and b> the spruce-

approximately the boundary line be- 
tween the Canadian and Alleghanian 
faunas, the line having been drawn by 
Prof. C. H. Feruald aud myself.
