SPRUCE CATERPILLARS. 843 
lighter than above, but similarly marked. Head and body pale lilac, reddish brown ; 
four black fine dots on each side above. Surface of the body with fine but obscure 
lines; two fine parallel dorsal lines on the last three abdominal segments. Length, 
26 mm . This is not a mimetic form, while No. 22 mimics the shape of a twig. 
24. Geometrid larva. 
This species occurred with No. 21. 
Larva. — Pale ash-gray, with black spots, resembling a bit of spruce twig. Head 
small, much narrower than the body, square, somewhat bilobed. Body narrowing 
towards each end, with the segments a little swollen behind ; third .abdominal seg- 
ment with a prominent black lateral tubercle; smaller but similar tubercles on the 
other segments. At each suture is a transverse, short, pale ash line flanked by a dark 
patch. Each thoracic and first abdominal segment with a triangular or V-shaped 
black spot, with the apex prolonged behind ; the marks are less distinct on the 
hinder part of the body. Body beneath nearly as above. Length, 24 to 25 mm . 
25. Geometrid larva. 
This caterpillar occurred ou the spruce Auguut 11, at Brunswick, Me. 
Larva.— Body thick, tapering a little towards both ends. Head rounded, not 
bilobed, as wide as prothoracic segment. Body with no spines or humps. Ground 
color pale light horn color, with a reddish tint, almost pale salmon, with four dark 
distinct, hair-bearing small warts above and one low down on each side. Five dor- 
sal slender wavy dark lines, the outer line embracing the dark small warts. On the 
sides of the body and beneath are similar dark wavy lines on a salmon ground. The 
head has six longitudinal diffuse lines. Length, 20 mm . 
26. The spruce epizeuxis. 
Epizeuxis cemula Hubner. 
Order Lepidoptera ; family Pyralhxe. 
While in the Adirondacks, in June, 1884, at Beede's hotel, Keene 
Flats, I beat from the spruce near the hotel two caterpillars, which I 
considered to be without doubt leaf-rollers of the family Tortricidce. 
They were in general appearance much like the Spruce Bud-worm (Tor- 
trixfumiferana), though a little smaller, but with a well-marked dorsal 
and lateral line, which are more characteristic of Pyralid than Tortricid 
larvse. 
Soon after, June 14 or 15, one of the caterpillars spun in the tin 
breeding box a cocoon covered with black scurf from the terminal twigs 
of the spruce. 
During the past season, in Maine, I collected another caterpillar on 
the spruce, June 9, but failed to make a description of it or to notice 
the number of abdominal feet; the moth appeared June 24. From 
this it would appear that the normal food-plant of the caterpillar is the 
spruce. 
There are four species of this genus of moths in this country*, the bet- 
ter known one besides the present species being E. americalis (or Relia 
americalis). But their habits are strangely dissimilar, since Prof. 0. 
V. Riley has stated in the American Naturalist for October, 1883 (p.
