CHERRY LEAF-MINERS. 527 



a foot iu 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 

 touud iu slight web like cocoons at the bottom of the breeding box. 



Larva. — Head as wide as the body, smooth aad rouuded, shiuiug, 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 band along the base of the legs. The yellow 

 band above includes three black shining warts on the sides of each segment. Anal 

 plate broad, obtuse, and black. Anal legs black above. Length, 1'2-13™">. 



Moth. — Body and wings pale fawn-brown. Forewings 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 ot 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'"™. 



14, Nepticula f 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 gatheretl 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 larvte. The mines are 

 reddish-brown after the larvse 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
