FAMILY SATURNIAD.E. 233 



Attacus luna. Green Emperor Moth. (Plate xxiv, fig. 1.) 



Actias ( Leach). Piial.ena luna ( Linnaeus.) 



Head small, white, encircled with a faint brown and narrow ring. Antennas brown, pecti- 

 nated. Thorax pale yellow and woolly, ornamented with a stripe in front continuous 

 with that upon the front margin of the wings. Wings pea-green, marked with eyelike 

 spots near the middle : outer margin bordered with purple brown. Posterior wings 

 prolonged into long narrow tails bending outwards. Body covered with a white wool- 

 ly substance, and rather close-pressed : legs purple brown. Expansion of wing about 

 five inches. 

 The caterpillar is fully grown about the first of August. It is of a bluish green color 



[wrongly colored in the figure], striped with yellow on the sides, and transversely also 



between the rings : rings marked by about six small reddish or purple warts. Length, 



when in motion, nearly three inches ; but when at rest, only about two inches. 



In feeding, it prefers the leaf of the hickory, though it may be kept upon the leaves of 



several of our forest-trees. In North-Carolina it feeds upon the leaves of the liquidanibar 



or sweet gum, as also upon the persimmon. 



N. B. In some of the figures I have observed that the body and abdomen are colored a 



light brown, the thorax and neck being yellowish white or cream-color in the animal. 



Hydrocampa? nivalis ( Harris). Delta-moth. 

 Upper side : Antennas filiform and brown. Wings pearly white, ciliated, and cilia brown. 

 Under side white pearly immaculate. Expanse'of wing 1 £ inch. 



Dryocampa imperialis (Harris). (Plate xl, fig. 7.) 



PHAJLSNA imperialis (Drury) ; P. imperatoria (Abbott & Smith, Insects of Georgia) ; Cerato- 

 campa (Harris, Catalogue of Insects of Massachusetts) ; Cerocajipa, Kirhy & Spence) ; 

 Lasiocampa (Latreille, Schrank.) ; Bombyx (Fabricius) ; Odonestis (Gcrmar, Stephens); 

 Bombyx didyma ( Pal. de Beauv. Ins. Lep. pi. 20). 



Male, upper side : Antenna? broad in the middle, pectinated, filiform, naked, and curved 

 at the extremities ; in the females, filiform, naked. Color reddish and yellow. Thorax 

 yellow, clouded by five brownish spots, the anterior one placed upon the median 

 line. Abdomen yellow, each ring of which is marked with broad heartform bands. 

 Wings yellow, sprinkled with brown purplish linear dots ; the outer edge broadly 

 margined with brown, which connects itself from its middle by a curved band with 

 the basal curved band : the connecting band curves and extends to the anterior 

 margin below the middle, and borders it to the base : the basal band extends along 

 the posterior margin beyond its middle, where it expands and encloses a yellow dot-
