that represented in Plate 8, fig. 15 c. Usually the larva draws 

 two leaves together, or folds one up, and as it eats its way 

 along the surface of the leaf, leaves its excrement filling up the 

 space behind, thus making blotches and otherwise disfiourino 

 the leaves. In this mine it transforms into a lono- slender 

 l)upa, which may be found surrounded with the castings of the 

 larva. The moths first appeared August 19th, and flew in-doors 

 at night attracted by the light. 



Bncciilatrix x>omoneUa Clem. (Plate 8, fig. IG, enlarged) is a 

 pale whitish species with yellowish scales, with a black line, 

 which beginning on the middle of the costa, curves around to- 

 wards the apex, ending in the usual eye-like spot on the outer 

 edge, beyond which is a dark marginal line ; in the middle of 

 the wing near the inner side is a longitudinal black oval spot, 

 paler within. The hind wings are pale gray, and the body and 

 legs pale whitish yellow. The Avings expand .30 of an inch. 

 We never met with the lar^-a, but the cocoon is long and slen- 

 der, a little blunt at each end and white, with slight longitudinal 

 ridges. It may be found attached to the bark on the branches 

 of the apple tree in ]May and also in the autumn and winter. 

 Besides differing from L. geminatella in making a regular co- 

 coon, the pupa is a little stouter and the top of the head is 

 blunter. 



Another species, which appears to be undescribed, we would 

 call the LithocoUetis nidificanselJa (Plate 8, fig. 19, moth; 19(/. 

 cocoon) from the singular way the cocoon is suspended in a 

 leaf like a hanging nest, by silken cords. The single speci- 

 men figured was found early in September, the moth appearing 

 on the 11th. The larva feeds on the pear, and when about to 

 transform had evidently drawn the edges of the leaf together 

 by a few threads, and then suspended its thin cocoon in the 

 manner indicated in the figure, the position of the chrysalis 

 being represented by the black line in the centre of the cocoon. 

 The moth is silvery white, with gray hind wings. The fore 

 Avings are white, with golden bronze streaks and spots. The 

 costa is white, with three oblique golden lines running out- 

 wards from the edge of the wing towards the outer margin, the 

 inner one being minute, and the outer one broad and less 

 oblique than the others. Beyond, are three apical straight
