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

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

 that this is the first bombycid to fly. 



Food ]>lants. — T'sually occurring on the aspen or Po^ml us treiimJoiden. I have also found it 

 on the yellow birch, one from this tree beginning to pupate August 11. Mr. n. S. Clark has bred 

 it from the Balm of Gilead, and S. L. Elliot found it on the willow and sweet gum. 



Geogviiphlvdl disirihiitiou. — This is a s]iccies of wide range, and so far as yet known is more 

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

 Middle States. 3Irs. Feruald has collected it at Orono, Me. I have found the larv;e commonly 

 at Ih'uuswick, Me., and Mrs. Slosson has collected the moths commonly from year to year at 

 Franconia, N. H., a very cool, elevated valley about 1,200 to 1,300 feet above the sea. Tlie 

 locality of Walker's type is "St. Martin's Falls, Albany River, Hudson's ]>ay, Dr. Barnston." It 

 has occurred at Cambridge, Mass. (Harris Coll. Bost. Soc. Nat. Hist.); Detroit, i\Iich. ; Lawrence, 

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

 and [Middle States (Grote, and Coll. Amer. Ent. Soc. Philadelphia); I'lattsburg, N. Y. (Hudson); 

 Carbondale, 111.; Wisconsin, Ohio, Maine, Middle States, New York (G. H. French); liacine. Wis.; 

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

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

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

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

 notliing. and so far as is known the species is restricted to the Appalachian snbprovince (or the 

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

The following description of the single female example forming the type of E<lwards"s irrujhiii 

 is copied from his jiaper in Eutomologica Americana (ii, i>. 11): 



GJuphisia irriglilii (u. sp.). — Head, thorax, and abdomen very dark gray, thickly speckled witli 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 line 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 sijuare bull' patch, 

 acro.ss which runs a black line. Sjiace behind the middle band blackish, shading into pale gray at the snbmargiiial 

 dentate line. Margin and fringe pale graj', spotted with black. Second.aries sordid white, with a dusky subniar- 

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

 median band. Expanse of wings, 42 mm., 1 9, San Bernardino, Cal. 



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

 present with 3Ir. Dyar that it is very near (/. rupta; we need more examples and a better knowl- 

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



As these forms have alreadj^ been described by Mr. Edwards, I copy his descriptions, adding 

 my own views as to their synonymy: 



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

 and legs also gray mottled with black. Antenna- with the shaft white, pectinations blackish. Primaries with a 

 bud' jiatch at the basi-, iu which are a few black scales. Behind this a gray band, edged before and behind with
