Dyar states that there are two broods each year, and 1 suspect this is the case, though I liave 

 not observed tliis for myself. Mr. G. 11. Hudson also thinks there are two broods, and writes me 

 that this is the flrst boiubycid to tly. 



Food j)lants. — Usually occurring on the aspen ov I'opulus treiiudoides. I have also found it 

 on the yellow birch, one from this tree beginning to pupate August 14. Mr. H. S. Clark has bred 

 it from the Ualm of Gilead, and S. L. I'^lliot found it on the willow and sweet gum. 



(Icor/i-Kphical diatribution. — This is a species of wide range, and so far as yet known is more 

 common in northern New England, especially in cool, elevated mountain stations, than in the 

 ]\Iiddle States. Mrs. Fernald has collected it at Orono, Me. I have found the larva- commonly 

 at Ihuiiswick, Me., and INIrs. Slossou has collected the moths commonly from year to year at 

 I'ranconia, N. H., a very cool, elevated valley about 1,200 to 1,300 feet above the sea. The 

 locality of Walker's ty])e is "St. Martin's Falls, Albany lliver, Hudson's Bay, Dr. Barnston." It 

 has occurred at Candjridge, Mass. (Harris Coll. Bost. Soc. Nat. Hist.); Detroit, 3Iich.; Lawrence, 

 Mass. (Mr. Treat, Mus. Comp. Zool.); Eastern New York (H. Edwards, Elliot, Dyar); New York 

 and ^Middle States (Grote, and Coll. Amer. Eut. Soc. Philadelphia); Tlattsburg, N. Y. (Hudson); 

 Carbondalc. III.: ^ViscoIlsin, Ohio, Maine, Middle States, New York (G. H. French); Eacine, Wis.; 

 Chicago, 111. (Westcott); Fort Collins, Colo., June 21 (C. F. Baker); Pennsylvania' (Strecker); 

 Manhattan, Kans., June 20, just like New England examples, but a little larger than any except 

 a bred one from Maine (Popenoe); New Y'^ork and Nebraska (U. S. Nat. Mus.), race quinquelinea 

 (PI. I, p. 4), Pacific Coast, northwest (Dyar). Of its distribution southward we as yet know 

 nothing, and so far as is known the species is restricted to the Appalachian subprovince (or the 

 humid province of the cold temperate subregion of the North American region, of Allen).

The following description of the single female example forming the type of Edwards's irrhjhtH 

 is copied from his paper in Entomologica Americana (ii. p. 11) : 



Gluphisia u-riyhlii (n. sp.). — Head, thorax, and abdomen very dark gray, thickly speckled with black scales, 

 but lighter on the underside; the primaries are also very heavily covered with black scales. A little above the 

 basal half of wing runs a waved liue of pale gray, and from internal angle another waved line more oblique. The 

 space between them is closely scaled with black, but toward the inner margin is an almost square butf patch, 

 across which runs a black line. Space behind the middle band blackish, shading into pale gray at the submarginal 

 dentate line. Margin and fringe pale gray, spotted with black. Secondaries sordid white, with a dusky sulmiar- 

 ginal shade, conuectnig with the blackish anal spot. Beneath smoky white, with faint indications of a double 

 median band. Expanse of wings, 42 mm., 1 $, San Bernardino, Cal. 



I have been led to reconsider my view as to the affinities of G. irrightii, and agree for the 

 present with JMr. Dyar that it is very near G. rupta ; we need more examples and a better knowl- 

 edge of the venation than we now pos.sess to settle the question of its exact relationship. 



As these forms have already been described by Mr. Edwards, I cojiy his descriptions, adding 

 mj- own views as to their .synonymy: 



Head, thorax, and abdomen dark gray, plentifully sprinkled with l>lack, especially on the upper side. Feet 

 and legs also gray nu)ttled with black. Antenuic with the shaft white, pectinations blackish. Primaries with a 

 buff patch at the base, in which are a few black scales. Behind this a gray band, edged before and behind with
