cous, with narrow lighter rings between joints. Eyes black, with greenish reflec. 

 tiou. 



Forewing: — -Basal patch large, occupying inner quarter of wing, mottled mass 

 of smoky-black and lilaceous scales, the black forming an irregular fascia through 

 centre of patch and also another on outer margin of patch, the scales of latter at 

 dorsum becoiring brown. Four black dots and four whitish dots on costa within 

 this space, outer line of patch outwardly oblique, irregular and with an acute 

 tooth projecting outwards at fold. Beyond basal patch is a broad whitish fascia, 

 cream and yellowish scales on costa and lower half and lilaceous scales on upper 

 half below costa, one large and two small black dots on costa and several black 

 scales over the lilaceous area. Outer edge of fascia nearly straight. Beyond is 

 abroad dark fascia narrow on costa and dorsum, but swelling out at middle in 

 width equal to a quarter of length of wing; smoky-black scales in upper half, 

 changing to yellowish brown on lower half. Beyond and outlining this is a very 

 irregular whitish fascia, broad on costa and to middle of wing, then contracted 

 and broadening out again to dorsum, where it reaches to anal angle. On costa, in 

 middle of this fascia, is an oblong streak of smoky-brown scales, and a small 

 rounded spot of same on dorsum, a few other dark scales are between these two 

 spots. Submarginal patch is large and touches margin only at middle, smoky- 

 brown, darkest at upper end; inner edge nearly vertical, outer edge evenly 

 rounded, e.xcept at lower quarter where it sharply broken or indented by a round 

 whitish spot, having a lilaceous center. Apical spot smoky brown, with cluster 

 of darker scales in center; separated from submarginal patch by line of whitish 

 and lilaceous scales. Three brown costal spots between apex and outer light fas- 

 cia. Cilia smoky-fuscous, mixed with bluish lilaceous, with a narrow dark inner 

 line. Hind wind dark smoky-fuscous, cilia lighter. Underside of both wings 

 smoky fuscous, with fascia and costal spots of upper surface of forewing repeated 

 in lighter and darker shades of fuscous. Abdomen above smoky-fuscous, tuft 

 yellowish brown, below paler fuscous. Legs fuscous, ringed and spotted with 

 dark brown. Expanse 10.5 to 11.5 mm.

Ill other specimens bred from Sumac the contrast in the vvliitish 

 and dark brown fascise are not so pronounced, caused l)y the de- 

 placement of the whitish scales by lilaceous or brown. In fact I 

 have very strong doubts of the authenticity of the records of these 

 particular specimens. (Riley, No. 5492, Dept. Agri.) The proba- 

 bilities are that grape and sumac larvae have been mixed under this 

 one breeding number. 



I have not bred this species, and of the nine specimens before me 

 all are from the hibernating brood, dates of issue December 28th, 

 January 9th, January 28th and March (5, Nos. 3342 and 3343, In- 

 sectory, Wooster, O., Murtfeldt collection ; January 2nd, January 

 12th, January 29th, No. 3257, Nat. Mus. ; and May 16th and 17th, 

 No. 5492, Nat. Mus., near Rochester, N. Y. All except last two 

 were doubtless forced, leaving middle of May as natural date of
