tinctly marked. Legs vei'y pale greenish, the last joint a little infuscated externally, 

 the tips of the claws reddish brown; prologs grass green, pale at tips. Length, 

 13 mm. ; breadth, 3.5 mm. ; height, 3 mm. ; length of longer hairs, .48 mm. ; of 

 shorter hairs, 12 mm. See also Mr. Saunders's descriptions and comments (Can. ent. ,

Chrysalis (84 : 25, 27). Thorax, wings and appendages dull, pale green, the thorax a 

 little dusky and abundantly dotted with small, blackish fuscous spots, arranged to a cer- 

 tain extent in streaks of varying disposition on the prothorax and the upper portion of 

 the sides of the niesothorax, the former sometimes with a distinct, blackish, dorsal line, 

 which becomes interrupted behind ; the wings with a few scattered dots on the upper 

 half. Abdomen pale yellowish or reddish brown, sometimes with a dirty, roseate tinge ; 

 a pale reddish, dorsal streak, marked irregularly, and sometimes centred with black 

 and bordered by a pale, whitish band, obscured by yellowish brown ; sides profusely 

 spotted with blackish fuscous, and bearing a lateral row of small, round, blackish 

 spots, which connect below with some blackish fuscous spots, and thus form short, 

 transverse streaks. The network of scarcely elevated, interlacing ridges is com- 

 posed of rather larger cells than in most of the species, covering most of the body, 

 and as distinctly on the sides as on the back, having no greater elevation at the inter- 

 section ; the hairs are pretty abundant, pale yellowish, moderately long, nearly equal 

 until close to the tip, where they taper to a tine point, fully half as long again on the 

 front as on the sides ; they are very minutely and delicately spiculiferous, the spicules 

 seldom visible as more than raised points, never exceeding one-fourth the diameter of 

 the hair, directed well forward, distant from each other generally by the width of 

 the hair. Spiracles pale green, with reddish lips, or reddish brown with pale lips. 

 Length. 9 mm. ; breadth, 4.25 mm. ; height, 3.75 mm. ; length of hairs in front, .3G mm. ; 

 length of haii-s on body, .23 mm. 



From specimens bred on oak and received from Mr. Sanndei'S. 



Another description. Greenish brown, more or less fuliginous, the raised tracery 

 of surface more or less infuscated. There is an obscure dorsal stripe on the protho- 

 rax and front of mesothorax, obscured by fuliginous; sides of mesothorax tinged 

 with fuliginous. Abdomen above with an obscui-e dorsal stripe, most distinct and 

 broadest on the third segment; and a series of dark, infralateral dots in the middle of 

 the segments, which become large, oblique, blackish blotches on the foui-th to sixth 

 segments; between this series and the wings, and including nearly the whole of the 

 second segment, the abdomen is liglit yellowish brown ; spiracles faintly brownish 

 fuscous. Wings dull, but pale Inteous, flecked with brown, the basal tubercle marked 

 above with black. Eyes black, conspicuous; prothoracic spiracle pallid. Beneath 

 wood brown, the apical halves of the appendages infuscated, the antennal clubs 

 blackish; an infuscated, ventrolateral band on abdomen. Hairs straight, slightly 

 tapering, bluntly pointed, faintly spiculiferous. Length, 10.5 mm. ; breadth of abdo- 

 men, 3.5 mm. ; of front of mesothorax, 2.7 mm. ; length of hairs on thorax, .15 mm. 



Described from specimen bred on butternut and sent by Mr. Hulbert. 



Distribution (24: 2). Tliis is much more extensively distributed than 

 the preceding butterfly, at least in latitude, being common to the Allc- 

 ghanian and Carolinian faunas and even encroaching a little on tiie 

 Canadian. Southward it occurs in Georgia "common" (Abbot), Alabama 

 (Gosse) and Virginia (coll. Anier. ent. soc). Westward it reaches to 

 Michigan (coll. Mich. Univ.), Wisconsin "not rare" (Hoy) and 

 Iowa, — Des Moines (Austin) and New Jefferson (Allen) ; and even to 

 eastern Nebraska (Carpenter), eastern Kansas rare (Snow), Colorado 

 and New Mexico (Snow), and northern Texas. If Boisduval's auretorum 

 be the same, as is probable, it even extends to California. Northward
