pachirdata in the g;roiind color being gray Avith the broad median area 

 bright chestnut brown. I feel sure the species is a perfectly distinct 

 one and not a variety of populata."' 



EUSTROMA NUBILATA Packard. 



Sixty-five specimens, May 31, June 1, 4, 10, 11, 15, 20, 23, 24, 30, 

 July 15, 18, 21 (Bear Lake ]Mountain), 23, 2I> (Bear Lake ^Mountain), 

 29, 30, August 1, 4, 5, 6, 7, 9 (South Fork Creek), 10 (Kokaiice Moun- 

 tain), 11 (South Fork Creek), 15, 21 (ReveIstoke),22 (Revelstoke),Saii- 

 don (G. C. Robbins). Probabl}^ double brooded, theliroods overlap[)iiitr. 

 The moths are rather variable, especially in the width of the pale trans- 

 verse-anterior band of the f orewings. One specimen is distinctly aber- 

 rant, the band being wide and pale,while the outward projection of the 

 dark median space is represented onl}^ b}' two short teeth and there is a 

 pale shade about the discal dot. The larva; were obtained from eggs 

 laid by a captive female and l)red on Ej'iJohiuin. The description will 

 appear in my Life Histories of North American Geometrida', LIU, 

 in Ps3'che. 



NEOLEXIA XYLINA Hulst. 



Twentj^-three specimens, July 2T, 29, 31, August 3, 4, 5, 6, 13, 15, 

 18, September 8 (Glacier), 9 (Field). A constant and characteristic 

 species. The larva was not found. 



RHEUMAPTERA HASTATA Linnaeus. 



Twenty -seven specimens; May 29, June 2, 8 (Ainsworth), 18 (Kaslo 

 Creek, Mr. Caudell), Julj' 21 (Bear Lake Mountain), Jul}' (near 

 McGuigan), 29 (Bear Lake Mountain), August 9 (South Fork Creek), 

 11 (South Fork Creek). Many more could have been taken, as the 

 species was very common at high altitudes. 



RHEUMAPTERA SOCIATA Borkhausen. 



Seven specimens; June 18 (Kaslo Creek, Mr. Caudell), 22, 23; July 

 21 (Bear Lake, Mr. Cockle), 25, August 1 (South Fork Creek) and one 

 from Mr. Cockle's collection, June 11. Agrees well with European 

 specimens. I have the species also from Oregon (Koebele), Seattle, 

 Washington (T. Kincaid), Vancouver (R. V. Harvey) and AVellington 

 (T. BrA-ant). 



RHEUMAPTERA LUCTUATA Schiffermiiller. 



Three specimens, August 7, 9 (South Fork Creek), II (South Fork 

 Creek, Mr. Cockle), all with black hind wings (var. ohductufa Mosch- 

 ler). I am clearly of the opinion that there are too many varietal names 

 recognized of this species. \\\\\<^i g\xos h)dial'ata^ ohductata^ and con-
