N0.137G. LEPIDOPTER A OF THE KOOTENAT DISTRICT— DYAR. 899 



HYDRIOMENE AUTUMNALIS Stromeyer. 



One specimen, July 2 and one from Mr. Co<-kle's collection, .lulv lo 

 (Ain.sworth). The specimens arc distinctly smaller than sordidata 

 Fabricius. 



HYDRIOMENE T.ENIATA Stephens. 



Five specimens, July 20 (Bear Lake), Auj^ust !» (South Fork Creek), 

 11 (South Fork Creek), much worn, hut apparently agreeino- with 

 Walker's hisalkda^ which stands as a s3'nonym of tiriiiiit<i. in our list. 

 I have one specimen of European txniata and I should hardly think it 

 conspecific with my Kaslo specimens. Hence this synonymy appears 

 doubtful to me, but I can make no positive statement with the present 

 scanty material. 



HYDRIOMENE EXCURVATA Grote. 



Three hundred and fifteen specimens, June 2(5, July 2,4, 11, li), 24, 



30, 31, August 3, 4, 5, 6, 11 (South Fork Creek), 12, 13, 15, 17. This 

 was the commonest species of Geometridic in Kaslo. It is the (Wa- 

 todalia gueneata of Packard's monograph. The larv{\i hibernate at 

 various stages and produce a single brood of moths. I have described 

 them in Life Histories of North American Geometridw, XLVIT." 



HYDRIOMENE MULTIFERATA Walker. 



Six specimens, May 31, June 4, 7, 8. The larva has been described 

 by me in Life Histories of North American Goonietrida', XLVl.'' 



HYDRIOMENE MAGNOLIATA Guenee. 



Thirty-five specimens, May 31. June 1, 3, 7, 10, 11, 1<), 18 (Kaslo 

 Creek, Mr. Caudell), 23, 25, July 13. 14, 15, 3 8, 29 (Bear Lake), 30, 



31, August 1, 2, 4, 5, 6, 7, 11 (South Fork Creek). The dates indicate 

 two broods. The larva has been descril)ed bv me in Life Histories 

 of North American Geometridtc, XLV,'' where 1 show that the 

 species is referable to Ili/drioiiitnt- instead of Cconoccdjie and that 

 Hulst's iKTnotata is a sjnionym. 



TRIPHOSA PROGRESSATA Walker. 



No specimens; one in ]\Ir. Cockle's collection. October 20. I should 

 have probably taken the species myself if I had remained later in the 

 season. 



GYPSOCHROA DESIGNATA Hufnagel. 

 No specimens; one in ]\Ir. Cockle's collection. ,Iune 4.
