H. pulclie?- Grote. 



Described from a single male from Colorado. Female undescribed. 



Grote's figure and description agree well with those of Moschler, although 

 there is a wide difference in locality. I am inclined to agree with Dr. 

 Dyar in making it a synonym of hyperboreus. I have seen no Colorado 

 material, but would place my species from Mt. Hood under this name, as 

 ihe males appear to agree. As in Jiyperboreus^ the band does not touch 

 ihe inner margin, and is more or less broken ; the arrangement of spots 

 on outer margin, costa and base is aho very similar. In the ten males 

 captured on Mt. Hood, considerable variation exists ; the band is mostly 

 broken and very irregular ; in three cases, however, it is entire, but in no 

 case Joes it approach the inner margin ; the silver spots of the outer 

 margin are always present, also the large spot at end of cell ; the costal 

 and basal spots vary somewhat in each specimen ; as stated above, four 

 of the females captured show no traces of silver, one being immaculate, 

 light brown, and the others with traces of a thin black line following the 

 general course of the silver band of the male sex. On spreading the 

 specimens I came across a single female with silver markings, which 1 had 

 evidently taken on the wing and confused with the males. The band is 

 entire and rather broad and regular, well removed from inner margin ; the 

 other silver markings are much reduced, but there are traces of spots 

 along outer margin. Long series from Colorado will be necessary to 

 establish the identity of our form.

Described from a series of specimens of both sexes from Truckee, 

 Calif As described by Edwards, the band is continuous and connected 

 with ihe inner margin by a spur of silver. The spots on outer margin are 

 lacking. Both sexes are similar. 



The species bears great resemblance to ganna Hbn., from Europe. 

 We do not know this species, but a figure is given in Spuler, Die 

 Schmetterlinge Europas. Dr. Barnes possesses a single 9 ^fom the type 

 locality ; further, four pairs from Hymers, Ont., collected by Mr. Horace 

 Dawson^ and three specimens from Calgiry, Alta. These all show a 

 marked similarity ; the band is continuous, the spur to inner margin 

 broad, and the silver spots of outer margin lacking ; the sexes are practi- 

 cally similar, and Mr. Dawson tells us that of about loo pairs captured 

 the females were in every instance silvered. Further, the species is a
