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. Lengthy 

 26™™. 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™™. 



25. Geomelrid larva. 



This caterpillar occurred ou the spruce Auguct 11, at Brunswick, Me. 



£arra.— 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 difl^use lines. Length, 20™™. 



26. The spruce epizeuxis. 



Epizeuxis asmula Hiibner. 



Order Lepidoptera ; family Pyralid^. 



While in the Adirondacks, iu 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 

 larvae. 



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 U. americalis (or JECelia 

 americalis). But their habits are strangely dissimilar, since Prof. 0. 

 V. Eiley has stated in the American Naturalist for October, 1883 (p.
