apical, which is given off near the tip of the wing. The discal nervure is 

 doubly angulated, and gives rise to the disco-central nervule at the angle on 

 the costal side ; and from the central, a false nervule to the base of the wing. 

 Median four-branched. Internal bifid at the base. 



In the hind wings, the costal and subcostal have a common trunk. The 

 subcostal bifid beyond the disk. The subcostal and median portions of the 

 discal nervure are much separated at their points of junction with the disco- 

 central, which is continued as a false nervule to the base of the wing. 



Male. Body stout and very short ; thorax covered with fiat hairs. Head 

 and eyes moderate, the latter oval. Labial palpi slightly exceeding the front, 

 rather stout, porrect, third joint very minute. No tongue. Antennae much 

 more than one half as long as the body, with the basal third pectinated. Ab- 

 domen shorter than the hind wings. The middle and hind tibiae rather thick- 

 ly ciliated ; apical spurs of hind tibiae, if present, inconspicuous. 



N. tardigrada . 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 papulae, of which the three anterior 

 and two posterior are more conspicuous than the rest. The superventral row 

 of papulae are moderate, equal, and form the outline of the body. 



General color very pale green, with dorsal patches of the general hue beau- 

 tifully margined by crimson lines, and crimson, vascular patches, of which 

 those between the fourth undjifth, seventh and eighth pairs of subvascular papu- 

 lae are most conspicuous, although small. All the papulae pale green. 



On the apricot in September. Imago in April. 



I have descriptions of other larvae similar in physical characteristics to the 

 above, but have not succeeded in carrying them through their transforma- 

 tions. 



The genera Pimela, Limacodes, Adoneta, Empretia and Nochelia belong to 

 that most anomalous family Limacodidae. Perhaps some of the groups de- 

 scribed as new have been heretofore established, but I found the effort to 

 identify them from meagre and unsatisfactory diagnoses of the imago an 

 almost futile task. 



Attacus Hubner. 



The following species have never been described I believe, except by De 

 Beauvois, and as his work is now rather rare and an expensive one, and not 

 accessible to tbe great body of American entomologists, I insert here de- 

 scriptions of the following insects :

Dull reddish-brown. Thorax banded with white before and behind. Ab- 

 domen with a white stigmatal band edged above and beneath with black and 

 containing reddish brown spots. Fore wings with a basal white streak ex- 

 tending from the costa to the base of medio-posterior nervule and thence to 

 the inner margin at the base of the wing, bordered toward the base with 

 orange-yellowish and externally by black. The breadth of the disk is occu- 

 pied by a large trigonate vitreous patch, extended behind so as to interrupt a 

 white wavy, narrow band crossing the middle of the nervules and which is 

 bordered internally with black and externally with orange-yellowish. The 

 trigonate patch is edged within by white and externally by black behind and 

 before. Beyond the transnervular band, the wing is brown dusted with 

 blackish and powdered with whitish roseate in the medio-posterior and sub-
