thai all the North American "species" of the genus thus far described are 

 variations of Abbot's nyssaria. 



Larva. — Body rather thick; head narrower than the body, which is green, 

 with a dorsal interrupted stripe descending on the sides of the thoracic and 

 terminal abdominal rings. In another larva (fig. 25), of a variety with the 

 wings bordered with red (a/nicaria), the larva is the same as in the one rep- 

 resented in fig. 19.- — (Described from Abbot's MS. drawings.) 



A MS. colored drawing by Abbot (copied on plate 13, figs. 19, 19 a, 

 pupa) represents the caterpillar as rather thick, but uniformly so, green, 

 with a violet dorsal stripe, and a similar lateral stripe on the sides at the end 

 of the body. Its food-plant is Hypericum rosmarinifolium. The pupa is 

 colored brown. 



The larva feeds on the beech, according to Mr. Saunders, who 

 informs me that it forms a rude case by binding two leaves together 

 with silk. It is an inch long and dark brown, with a row of dull-white dots 

 on each side. On the posterior part of the ninth segment are two rather 

 prominent, rounded, black tubercles, with a few streaks of whitish at their 

 base anteriorly. The terminal segment is flattened and of a bluish tint. 



Desideratum. 



Selenia cesionaria Walk., List Lep. Het. Br. Mus., xx, 182, 1860, — "Male. 

 "Whitish ochraceous, darker beneath. Palpi extending a little beyond the 

 head; third joint conical, very minute. Wings thickly blackish-speckled;. 

 exterior line brown, slightly undulating, diffuse on the outer side. Space 

 between it and the exterior border purplish-tinged; exterior border forming 

 a much rounded angle. Fore wings rectangular at their tips; interior line 

 brown, slightly undulating and angular, diffuse on the inner side; discal 

 lunule blackish ; exterior line forming an extremely deep bend opposite the 

 angle. Hind wings with a brown discal point; exterior border excavated on 

 each side of the angle. Length of the body 6 lines; of the wings 18 lines. 

 New York." 



This is certainly a species of Hyperetis, as 1 learned by examination of 

 Walker's type in the British Museum. It was apparently distinct from H. 

 nyssaria.
