NOCHELIA. 131 



E. paenulata Clemens. Proc. A. N. S. Phila. p. 159, 1860. 



Body dark reddish-brown. Fore wings dark reddish-brown 

 along all the borders, with a large central pea-green patch, ex- 

 tending from the base of the wing to the subterminal portion, 

 bordered narrowly on the inner side and behind with white, and 

 deeply indented opposite the middle of the inner margin, where 

 there is a bright brown patch in the reddish-brown border. Hind 

 wings yellowish-brown. 



I do not know the larval state of this species, and have only 

 two specimens, both apparently females. T can perceive no differ- 

 ence in the structural characters of the imago of this and the pre- 

 vious species, and am quite sure that they belong to the same 

 generic group. The discovery of the larval form will, however, 

 determine the question.

NOCHELIA CLEMENS. 

 N. tardigrada Clemens. Proc. A. N. S. Phil. p. 159, 1860. 



Male. Body and fore wings rather dark reddish-brown, with a 

 small, nearly triangular pea-green patch narrowly bordered with 

 dark brown at the base of the wing, beneath the median nervure, 

 slightly excavated behind where it adjoins a bright brown patch. 

 Towards the hind end of the disk, in its middle, is a minute oval 

 dark brown streak; two small pea-green subapical spots, the one 

 nearest the costa minute. 



Larva. The body is elliptical, much flattened above. There 

 is on each side a row of subvascular, minutely spined papula?, of 

 which the three anterior and two posterior are more conspicuous 

 than the rest. The superventral row of papula are moderate, 

 equal, and form the outline of the body. 



General color very pale green, "with dorsal patches of the general 

 hue beautifully margined by crimson lines, and crimson vascular 

 patches, of which those between the fourth and ffth, seventh and 

 eighth pairs of subvascular papula? are most conspicuous, although 

 small. All the papula? are pale green. 



On the apricot in September. Imago in April. 



The genera Pimela, Limacodes, Adoueta, Empretia, and No- 

 chelia belong to that most anomalous family Liuuacodida?. Per-
