CHERRY LEAF-MINERS. 527 
a foot in length, as late as October 12, at Providence. Some of the 
leaves were dead and dry, others had been freshly tied October 5. 
Two or three larvae inhabit the same leaf; the leaves are cut off at the 
base of the stalk, and the edges are sewed together here and there, 
the silk extending along the seam. October 12 several chrysalids were 
found in slight web like cocoons at the bottom of the breeding box. 
Larva. — Head a3 wide as the body, smooth and rounded, shining, bright cherry-red ; 
distinctly bilobed. Body smooth, scarcely wrinkled, dull black, with four equidis- 
tant much broken yellow hair-lines, being so many rows of fine dots. Lower and 
under side bright straw-yellow, with broken interrupted dusky lines, .and including 
the spiracles. A longitudinal black baud aloug the base of the legs. The yellow 
baud above includes three black shining warts on the sides of each segment. Anal 
plate broad, obtuse, and black. Anal legs black above. Length, i2-13 mm . 
Moth. — Body and wings pale fawn-brown. Fore wings with about twelve well" 
marked, white, scalloped, parallel, approximate lines, becoming more deeply scal- 
loped beyond the discal spot, which is large, black, with one of the dark lines run- 
ning through it ; the brown lines alternating with the white ones become blackish 
toward the base of the wing ; the submarginal white line is more zigzag than the 
others, and situated half way between the edge of the wing and the next white line. 
On the hind wings are about six light lines, becoming whitish toward the outer edge 
of the wing, as well as more zigzag ; the lines are heavier than on the forewings ; 
beneath, the wings are clearer, with the lines more or less obsolete, and the discal 
dots large and distinct. Length of body, male, 0.50, female, 0.50 ; expanse of wings, 
1.55 inches. 
13. Eupithecia? sp. 
The caterpillar described below was found feeding on the wild cherry 
at Berlin Falls, N. H., September 13, 1887. 
Larva. — Eupithecia-like in shape, the body being very slender, increasing in width 
behind. Head as broad as the body in front, somewhat bilobed, but smooth and 
rounded. Body pale dull amber, with a dark square dorsal patch on each segment, 
and one on each side alternating in position with the dorsal ones. Two lateral 
linear dusky lines. Body beneath pale, with no ventral line. Length, 12 mm . 
14. Nepticula ? prunifoliella Clem. 
Mines resembling those of the Nepticulce may be found in the leaves 
of the wild cherry, Prunus serotina, during the latter part of July and 
early in August. It is more or less blotchy in the beginning, with frass 
dispersed and towards the end gathered into a rather broad line, with 
the grains distinct. I have never found them tenanted, and it is quite 
possible that they are the work of Dipterous larvae. The mines are 
reddish-brown after the larvae leave them. (Clemens.) 
15. Aspidisca saliciella Clem. 
A larva of this genus mines the leaves of wild cherry in July. The 
mines are usually near the base of the leaf, and are more elongated than 
any others I have found. The mine is a short tract, not broader than 
the short diameter of the disk, which is cut out from the end of the
