[495] LEPIDOPTERA 221 



character in some species. The subterminal line is geminate, waved, 

 lighter at the outset, beginning with a hook on the costa and showing 

 a few golden scales at the lower end, especially on the small tooth 

 opposite the sign. The median space below the sign is the darkest 

 part of the wing, the deepest black being immediately next to the sign. 

 The subterminal line is black and shows distinctly against the paler 

 shade between it and the fringes. It is sharply angulate and dentate. 

 The two teeth at the center of the line are sharp, but near its anal angle 

 there is no sharp tooth as in allied species, the angle being rounded. 

 Fringes gray, cut with blackish. Orbicular indistinct, purplish, lined 

 with black. Reniform upright, concolorous, outlined by faint metallic 

 scales. Secondaries smoky yellowish basally with a wide darker outer 

 border. Beneath, primaries smoky with yellowish discal spot, the 

 white spots in costa and in fringes showing more distinctly than above. 

 Secondaries much lighter. 



Expanse 34 mm. 



Habitat. Alaska. 



Type. Cat. no. 5256, U. S. National Museum. 



Hypena californica Behr. 



Hypena californica BEHR., Trans. Am. Ent. Soc., 3, 23, 1870. 



One example : Virgin Bay, Prince William Sound, June 25. 



Professor Smith saw this specimen and said: "Does not differ in 

 any notable particular from British Columbia examples. One ragged 

 female." 



Family GEOMETRIC. 

 Mesoleuca variata Schiff . 

 Mesoleuca variata SCHIFF., Syst. verz. Wien. geg., no, 1776. 



Twelve specimens: Popof Island, July 1215. 



Determined by Rev. Dr. Hulst as a "small variety" of Mesoleuca 

 truncata Hufn., but I cannot agree with this determination. 



Mesoleuca lacustrata Guen. 



Mesoleuca lacustrata GUEN., Phal., 2, 395, 1857. 



One example: Yakutat, June 21. 



Named by Dr. Hulst ; but it is distinctly different from Eastern ex- 

 amples of this species. 



Petrophora montanata Borkh. 



Pttrophora montanata BORKH., Nat. Eur. Schmett., 5, 397, 1794. 



One example, large : Popof Island, July 10. Sixteen examples : 

 Popof Island, July 9-15 ; Kukak Bay, July 4. 



One of the latter examples was submitted to Dr. Hulst, who pro- 

 nounced it a very light variety of the same species ; I would determine 

 the species as munitata^ not montanata.
