356. CucuUia montancE Grt. — I have no note of having seen 

 the type of this species, which, according to Smith's Catalogue, is 

 in the Neumoegen collection at Brooklyn, nor have I seen Grote's 

 description. The Calgary form, however, agrees with the descrip- 

 tion of montance in Smith's Monograph, and is also the montancB 

 of the British Museum collection, with the exception of the actual 

 specimen figured by Hampson, which happens to be a Denver, 

 Colo., specimen of asteroides, of which the type is correctly figured 

 on the next plate. It had not, until recently, occurred to me that 

 there was any likelihood of confusing the two, but I must admit 

 that I have examined, and now possess, specimens which I have 

 had considerable trouble in determining. Generally speaking, 

 whilst the arrangement of colour in the two is about the same, the 

 shades in montancB are more intense, that is, the pale shades are 

 paler, and the dark shades darker. But the colour varies some- 

 what in different localities, and more reliable points of distinction 

 are as follows. In montancB, the basal area, as far as the t. a. line, 

 is very pale fulvous. The t. a. line is double, with the included space- 

 of the same pale gray colour as the central and outer middle por- 

 tion of the wing below the spots. In asteroides the basal space is 

 unicolorous with the central and outer middle area, and the t. a.- 

 line is single, though traces of an inner portion are sometimes 

 discernible. In asteroides the tegulse have a black line near the 

 base, which seems to be lacking in my montance, though Hampson 

 gives it as present in both. Slightly worn or poorly-marked speci- 

 mens are occasionally extremely difificult to place. I have not 

 both species from one locality. Montance is recorded from 

 Colorado, and I think I saw it from there in the British Museum, 

 but a Colorado specimen in my collection, sent as montance, ap- 

 pears to me to be asteroides. I am certainly strongly under the 

 impression that the two are distinct.
