320 LEPIDOPTERA. 



square above, and whitish green, with three longitudinal brown 

 lines. The prothoracic ring is concolorous with the head, from 

 which two brown lines extend, forming an inverted V on the 

 hinder edge. The body is pale grass green above, with the 

 sides bulging. There are four minute black dots on each ring, 

 a whitish, indistinct subdorsal line, and a lateral white line ex- 

 tending to the sides of the anal legs. The bod}- is greenish 

 white. The moth (Plate 8, fig. 5, male) is of a rich yellow, 

 with brown patches on the wings, and appears in July. 



In Endropia, which is closely allied to Choerodes, the outer 

 edge of the wings is deeply notched. E. tigrinaria Guenee 

 is dirty ochreous, the wings being sprinkled with black ; the 

 outer line is nearl}'' straight, ferruginous, paler within, with 

 some submarginal spots, and the basal line on the fore wings 

 is angulated, while the apex is pale and margined externally 

 with blackish. 



Metrocampa is pearly white, with the wings a little bent in 

 the middle. M. perlata Guen. is pure white, with two darker 

 oblique lines not angulated ; it is found not uncommonly north- 

 ward. The larva of the English M. margaritata has twelve 

 legs, and like Catocala has fleshy filaments on the sides just 

 above the legs. The pupa lives on the surface of the earth. 



Ellop)ia has pectinated antennae and exceeding!}^ thin trans- 

 parent wings, which are angulated in the middle of the outer 

 edge, and with an inner and outer line, the latter bent nearly 

 at right angles. The larva has twelve legs, but is smooth. 

 The English E. fasciaria feeds on firs. Ellopia Jlagitiaria 

 Guenee is pale ashen ochreous, with the speckles and two bands 

 pale brown. It expands from six to eighteen lines. 



In Cabewdes the antennie are broadly pectinated, and the 

 apex of the fore wings is nearly rectangular. The species 

 are pale ochreous with thick wings, and the outer line termi- 

 nates near the apex. C. metrocamparia Guenee is common 

 northwards; with a blackish discal dot and outer dusky line 

 arcuated and margined with white. 



The genus Nematocampa is characterized by the four fila- 

 ments on the back of the larva. N. Jilamentaria Guen. (Plate 

 8, fig. 7; 7a, larva) is a small moth of a pale ochreous color, 

 with reddish brown lines and dots, a ring in the discal space,
