NADATA GIBBOSA Smith and Abbot. 



One specimen, June 2. The form is normal, like specimens from 

 the Atlantic coast, not like the peculiar red or pale yellow forms that 

 occur in certain places. The yellow marking- in the cell of fore wing 

 is well contrasted. 



SCHIZURA IPOMCE/E Doubleday. 



One specimen, July 4. Of the normal form without an}" black 

 shadino-s. The species occurs throughout North Amei'ica, except pos- 

 sibly in the Southwest. The well-known larva was not seen at Kaslo. 



SCHIZURA CONCINNA Smith and Abbot. 



No specimens; Mr. Cockle has taken it. 



SCHJ.I'URA UNICORNIS Smith and Abbot. 



No specimens; Mr. Cockle has taken it. 



SCHIZURA PERANGULATA Hy. Edwards. 



No specimens; one in Mr. Cockle's collection, without date. With- 

 out a series I can not say positively that this is a local race, but such 

 is probabl}^ the case. The specimen is nearest to one which I have 

 from Ogden, Utah, as distinguished from others from Colorado. It 

 has the fore wings a bright, nearly uniform gray, all the markings 

 obliterate, except a heavy black shade at base and along basal two- 

 thirds of inner margin. The basal dash is present and the reddish 

 shade on inner margin faintly so. Hind wings pure white, scarcely 

 soiled at anal angle. 



HARPYIA SCOLOPENDRINA Boisduval. 



No specimen; Mr. Cockle has some referable to a form of this 

 species. 



GLUPHISIA SEPTENTRIONALIS ^A/•alker. 



One specimen, July 25, and one from Mr. Cockle's collection, Jul}^ 

 2, 1901. Mr. Cockle has taken others. They are of the form qitm- 

 quelinea Dyar, which was described from Portland, Oregon. The 

 larva was not seen; it feeds on aspen and cotton wood. These trees 

 occur everywhere from the cold woods of Maine to the sun-baked 

 arroyos of Arizona, and Gluphisia accompanies them. Naturally the 

 adult varies much in appearance from the dark forms of the northern 

 woods to the pale, almost white ones of the southern deserts. The 

 North American forms have been variously called septentrionalis, clan- 

 dest'ina^ trilineata^ ridenda^ quhujaellnea, wrightil^ cdhofascia., rnpta^ 

 Sind formosa, all described as good species. They have been gradually
