times has defoliated spruce and firs over extensive tracts on the coast of 



Maine ; the moth lays about thirty eggs 

 which are flat, scale like, slightly 

 convex above, with a thin shell; the 

 worm feeds on the buds and terminal 

 shoots in June. Our most common 

 leaf-roller is Gaaeda rosaceana Harris, 

 whose green larva?, with a black head 

 and prothoracic shield, fold the leaves of 

 the apple, plfim, cherry, rose, and other 

 plants. The cranberry worm (Rhopo- 

 boia weciniana Pack.) often injures 

 the cranberry plants. The strawberry 

 leaf-roller, Pkoxopteris fragaria (Walsh and Riley), folds the leaves. 

 Family Pyralidae. — The moths of this group have slender bodies 

 and legs, the fore wings are usually narrow, the hinder pair broad 

 and somewhat pointed at the apex; the palpi are often held straight 

 out, and are usually long and slender. The larvae are easily con- 

 founded with the leaf-rollers, hut nre usually more or less striped, 

 those of the Phycids being often brownish. There are three sub- 

 families, viz., the OrambincB, Phydnm, and PyraliruB. 



The species of Crambua are often very destructive to grass. The 

 larva of C. mlgiwfellus Clemens (Fig. i 86), which ravaged the pas- 

 tures and meadows of New York in 1881, is pale purple green, with 

 a black head; it forms a silken tube near the roots of grass, and 

 pupates in thin, Blight cocoons just under the surface of the ground. 

 To this group belongs the bee-moth {Ghtileria melonella). Among 

 Phycinae, the currant and gooseberry fruit-worm (Dakriima con- 

 volutella Hiibner) is noteworthy. Of the Pyralinoe, Asopia farinalis 

 Harris in the larval st a ge feeds on meal, etc.; other typical forms 

 are the species of Botys. while aquatic larva, living in cases, are 

 species of Hydrocampa, Cataclysta, and Paraponyx.
