NO. 1376. LEPIDOPTERA OF THE KOOTENAI DISTRICT— BYAR. 913 



My specimon was a tVniiil(> and deposited eggs which hatched and were 

 carried to stago v when they were all lost ])y a fungoid disease. I 

 have desci'ihed the larva in Life Histories of North Aniericaii (ieoiiie- 

 tridte, XXXII. " 



EUCHLiENA ASTYLUSARIA Walker. 



Nine specimens, June i), 19, 24, 25, 27, July 2. They agree with 

 Coloradan examples. As compared with eastern specimens they are 

 more yellowish, the striga? fewer and less defined, the dark shade 

 bey^ond the transverse posterior line lighter and either partially or 

 wholly wanting. This may be Hulst's )iiai)uhriat<i^ which I do not 

 know. I will describe the larva; in Life Histories of North Amer- 

 ican Geometrida% LIX. 



EUTRAPELA ALCIPHERARIA Walker. 



One specimen. May 30. The specimen was a female, but the eggs 

 were infertile. L have the larvte from Mr. Theodore Bryant, Welling- 

 ton, who points out to me that the two broods of the species are 

 different, the spring brood being large and heavily marked, the sum- 

 mer brood small and lightly marked. I have descri])ed the larva' in 

 Life Histories of North American (reometrida', III.'' 



METANEMA TEXTRINARIA Grote and Robinson. 



Two specimens, flune S (Ainsworth), 11, and one from Mr. Cockle's 

 collection. 



AZELINA ANCETARIA Hiibner, var. OCCIDENTALIS Hulst. ' 



Twenty-six specimens, Jul}^ 15, 26, 29, 30, August 4, 5, 6, 7, 12, 21 

 (Revelstoke). This is, 1 think, Hulst's Marmarea occidentallx. Only 

 two of my specimens are males. In describing occidenttiJh, Doctor 

 Hulst calls it a "Darwinian species" — that is to say, in this case, a 

 geographical race — and he erects the new genus for it on the slight 

 difference in the male antenna^. In the Kaslo si:)ecimens this is cer- 

 tainly extremeh' slight. Neither is it greater in specimens from 

 California and Arizona before me. The Kaslo specimens are all 

 decidedly larger than eastern ancetaria^ agreeing with Doctor Hulst's 

 specific diagnosis of occidental U. So while there is a possil>iIity that 

 I have not the true occldentidix, I do not think this is the case. I am 

 of the opinion that when a character is admittedly not of specific value 

 it can not be used to define a genus, even if it be "structural." 

 Therefore 1 place Hulst's genus Marumvea as a synonym of AzrJiiui 

 and his species occidental Ik as a variety of ancetaria. The life history 

 was started, but I failed to complete it.
