are a little larg-er than the European form and without an}- brown 

 tint. Some of my specimens from Norway are of exactly the same 

 color. This may be T. perfusca Hulst. It is obviously the same as 

 the Alaskan specimens named perfuaca for me by Doctor Hulst, but 

 Hulst's t^-pe from Utah before me is so poor that I can not tell what 

 it is like. Eggs obtained from a captive female proved sterile. 



Egg. — Elliptical, well flattened, rounded, truncation and depression 

 distinct, all rounded; uniformly reticulate with waved reticulations, 

 broad, rounded, forming- cells with five lobes but not neatly, not very 

 distinctly, and tending to run in the long diameter. Yellowish white, 

 shining; size, 0.6 by 0.5 by 0.4 mm. 



TEPHROCLYSTIS LARICATA Freyer. 



No specimens; one in Mr. Cockle's collection conies near the Euro- 

 pean Jarlada. The markings are more pronounced and contrasted, 

 the outer pale band being broader and less obscured by its centering 

 line. The discal dots on both wings are well marked. 



TEPHROCLYSTIS MULTISTRIGATA Hulst. 



One specimen, April 1^2 (Mr. Cockle), and one in Mr. Cockle's col- 

 lection, May 7, agree in general with a specimen from Calgary, Alberta, 

 communicated to me b}^ Mr. George W. Tajdor. The agreement is 

 not absolute, but I will not venture to separate them on the present 

 slender material. 



TEPHROCLYSTIS NIPHADOPHILATA, new species. 



Twenty specimens, June 7, August 10 (Kokanee Mountain, on snow), 

 September 8 (Glacier), 9 (Field), and two from Mr. Cockle's collection, 

 August 22, 1901. Dark gray, the wings rather pointed; a light band 

 followed by black on basal segments of abdomen. Lines not con- 

 trasted, both well angled subcostally, the veins marked with black 

 dashes, especially the median vein and those before the transverse pos- 

 terior band. Subterminal line faint, pale, not forming a dot above 

 tornus. Discal spot black. Hind wings gray, subpellucid, with gray 

 lines on the inner margin and two faint outer pale lines across the wing. 

 Expanse, 21: mm.

One specimen, June 16, and one in Mr. Cockle's collection, Jul}' 17, 

 1901. Gra}^, the dark band on second segment of abdomen not con- 

 trasted. Wings nearly uniform gra}^ the lines nearly obsolete, pale; 

 discal spots large, black. Hind wing indistinct!}' lined, with small, 

 faint, discal dot. Expanse, 26 mm.
