Hemileuca Maia var. Lucina n. v;u\ 



A form occuring in Maine, and probably in other of the northern 

 portions of our continent, which appears to deserve at least a varietal 

 name. It is intermediate between H. Maia and H. Neuadensis, having 

 the primrose band uniformly broad on the primaries and including the 

 discal ocellus, and that of secondaries always wider than in any examples 

 of H. Maia seen by me. This band too is of rather different shape, and 

 invariably reaches the posterior margin farther from the anal angle than 

 is the case with H. Maia. The wings too are much more transparent 

 than those of the common form, and in some cases appear to be almost 

 denuded of scales. I have during the past summer examined upwards 

 of 300 specimens of H. Maia, many of which were raised from the egg, 

 but though varying considerably among themselves, in the width and 

 density of the band, I have seen none that I could not very readily 

 separate from the form now under notice. My specimens (3 tf, 2 Q ). 

 are all from Norway, Me., and from near Bangor, Me. 



Lophodonta plumosa n. sp. 



Head, thorax, palpi, and abdomen brownish gray, the latter blackish at its base. 

 Antennae with extremely long pectinations, giving them a plumose appearance. 

 Primaries brownish gray, with the nervules black. A linear discal spot surrounded 

 by a buff shade, a sub-marginal slightly waved line, composed of blackish spots, 

 between the nervules. There is a whitish cloud on the middle of the costa, and the 

 whole surface is thickly flecked .with black scales. Secondaries sordid white, the ab- 

 dominal margin yellowish, the posterior margin distinctly dusky, the dark shade 

 widening at the apex. Fringe sordid white. Beneath sordid white, the costa of 

 primaries dusky, and the submarginal line faintly shown. Expanse of wings 45 mm. 

 Length of body 22 mm. I $. Denver, Colorado. 



A very distinct and strongly marked species, unlike anything else 

 known to me. I place it provisionally here, the plumose antennae, and 

 the absence of the tuft at the internal angle of primaries, probably en- 

 titling it to generic rank. 



Hepialus McGlashani n. sp. 



Primaries yellowish fawn-color, of a brighter tint than any North Amer. species 

 previously known to me. From the middle of the base runs a rather broad, very 

 distinct, uneven silvery white line, which traverses the whole extent of the wing, and 

 is entire and uninterrupted throughout its whole course. It runs from its starting 

 point in a curve to the sub-costal nerve near the upper end, of the cell, thence obliquely 

 to the internal margin, which it touches by a projecting tooth and thence directly to 

 the apex. It has in the submarginal portion a tooth on each side near the middle of 

 the wing, the posterior one being connected with the margin by a small white dash. 

 Near the base of the internal margin are three small white dots, and along the costa 

 are 6 others, the fourth of which is the largest, and is nearly connected with the for- 

 ward tooth of the submarginal band. The secondaries are smoky, edged rather 

 broadly with yellowish fawn-color. The fringes of both wings, as well as the thorax 

 and head are of the same shade as the ground color of the primaries. The abdomen 

 is pale smoky. Beneath, wholly smoky, the margins fawn-color, with a pinkish
