Dyar states that there are two broods each year, and I suspect this is the case, though I liave 
not observed this for myself. Mr, G. H. ITudsou also thinks there are two broods, and writes me 
that this is the first bombycid to fly. 
Food2)Ianfs. — Usually occurring on the as])eu or Fojmhis tremidoides. I have also found it 
on the yellow birch, one from this tree beginning to pupate August 14. Mr. II. S. Clark has bred 
it from the Balm of Gilead, and S. L. Elliot found it on the willow and sweet gum. 
Geographical ditifribiiiion. — This is a species of Avide range, and so far as yet known is more 
common in northern New England, especially in cool, elevated mountain stations, than in the 
Middle States. 3Irs. Fernald has collected it at Orono, Me. I have found the larvjc commonly" 
at Brunswick, Me., and Mrs. Slosson has collected the moths commonly from year to year at 
Franconia, N. II., a very cool, elevated valley about 1,200 to 1,300 feet above the sea. The 
locality of Walker's type is ‘‘St. Marlin’s Falls, Albany River, Hudson’s Bay, Dr. Barnston.” It 
has occurred at Cambridge, Mass. (Harris Coll. Bost. Soc. Nat. Hist.); Detroit, Mich.; Lawrence, 
Mass. (Mr. Treat, Miis. Comp. Zook); Eastern New York (H. Edwards, Elliot, Dyar); New York 
and 31iddle States (Grote, and Coll. Amer. Ent. Soc. Philadelphia); Plattsburg, N. Y". (Hudson); 
Carbondale, Ilk; AYisconsin, Ohio, Maine, Middle States, New York (G. H. French); Racine, Wis.; 
Chicago, Ilk (AVestcott); Fort Collins, Colo., June 21 (0. F. Baker); Pennsylvania (Strecker); 
Manhattan, Ivans., June 20, just like New England examples, but a little larger than any except 
a bred one from Alaine (Popenoe); New Y"ork and Nebraska (U. S. Nat. Mus.), race qumqiieUnea 
(PI. I, p. 4), Pacific Coast, northwest (Dyar). Of its distribution southward Ave as yet know 
nothing, and so far as is known the siiecies is restricted to the Appalachian subprovince (or the 
humid proA'ince of the cold teiniierate subregion of the North American region, of Allen).

The following description of the single female example forming the type of EdAvards’s wrightii 
is copied from lus paper in Eiitomologica Americana (ii, p. 11): 
Gluphisia icrighiii (u. sp.). — Head, thorax, and abdomen A’ery dark gray, thickly speckled with black scales, 
hut lighter on the underside; the ]»rimuries are also very heavily covered with black scales. A little above tlie 
basal half of Aving runs a waved line of jiale gray, and from iuterual angle another Avaved line more oblique. The 
«pace between tbem is closely scaled Avith black, but toAvard the iuuer margin is an almost square buff patch, 
across which runs a black line. Sjiace beliiud the middle baud blackish, shading into pale gray at the submarginal 
dentate line. Margin and fringe pale gray, spoiled with Ithick. Secondaries sordid white, with a dusky suhaiur- 
ginal shade, connecting Avith the blackish anal spot, lleneath smoky Avhite, with faint indications of a double 
median hand. Expanse of Avings, 42 mm., 1 $, San Bernardino, Cal. 
I have been led to recoimider my vieAv as to tlie affiTiities of G, wrightii^ and agree for tlie 
present with Mr. Dyar that it is very near G. rupta; we need more cxamides and a better knowl- 
edge of the venation than Ave now possess to settle the question of its exact relationship. 
As these forms haA’e already been described by Mr. Edwards, 1 copy his descriptions, adding 
my own views as to I heir synonymy: 
Head, tliorax, and abdomen dark gray, plentifully sprinkled with black, especially on the upper side. Feet 
-and legs also gray mottled Avith black. Aiitenum with the shaft Avhite, pectinations blackish. Primaries with a 
buff patch at the base, in Avhich are a few black scales. Behind this a gray hand, edged before and behind with
