with a torous decorative spot on the first ring. The genuine Tolype being allied to the generic type velleda 
exhibit on the mesothorax very peculiar large spatulate or oar-shaped hairs of a blackish-brown colour with 
a more or less intense steel-blue reflection; in the velleda- group they occupy the whole length of the thorax, 
whereas in brevicrista, mollifada, and vemerila they are only on the metathorax. In the innocens- group such 
long-stalked spatulate hairs are on the abdomen, most of the other Tolype are without them. Whether according 
to these differences other genera are to be separated, cannot be decided at present. 
Dr. Harrison G. Dyar, Washington, had the kindness to characterise for us the very difficult North 
American forms of Tolype, though, as lie writes, without any very satisfactory result; for beside the great 
individual variability, it is at present impossible to say what constitutes a species and what a form. Thorough 
examinations, particularly of the genitals, are therefore here more necessary than in other genera, and the 
accurate division of this genus must be left to the future. 
Type: T. velleda Stoll. 
T. velleda Stoll is the oldest name of a group of allied forms in which the forewing is whitish with 
a broad blackish median and subterminal band both of which are more or less crossed by white veins and 
accompanied by more or less distinct narrower linear stripes. — velleda Stoll (81 a) is the largest species of 
the eastern U. S., both sexes similar; thorax white, markings of forewing shaded, the dark colour grey, extensive, 
so that the fore wing seems grey marked with white lines. Larva brown with darker longitudinal lines and a 
bluish-black decorative spot on the 3rd ring, it lives on oak and changes into an obtuse brown pupa in a long 
yellow web. As long as so little is known about the different forms, we prefer cpioting them in the usual way 
as species. 
T. minta Dyar (81a) is very similar to velleda, but smaller and from Florida. Perhaps only a southern 
race of velleda. 
T. glenwoodi Barnes (81 a) is likewise smaller than velleda, the markings darker and more sharply 
cut, the median grey space of the fore wing generally narrower. From Colorado and New Mexico. 
T. dayi Blacbnore is hardly discernible from glenwoodi and may be only a local form of the same 
species. From British Colombia. 
T. lowriei B. & McD. (81 a) is very similar to glenwoodi and perhaps a race of it from California. 
The S' is whiter than most glemvoodi, more like the $ which has no tangible differences from glenwoodi- $. Com¬ 
pared with minta it is larger, the distal border of the median band more regular. The larva is greyish-brown, 
in the black decorative spot there are 2 yellow dots; on the dorsum darker spots. It lives on Abies. 
T. laricis Fitch (= minuta Grt.) (81 b). The S is black, the $ white, the S very black and with only 
traces of pale lines on the wings, the $ similar to that of velleda, but separable by much smaller size, whiter 
abdomen and often a broad white space in middle of forewing. Atlantic States. 
T. distincta French (81 b). Thorax dark grey in the <S> pale grey i * 1 the $; veins of fore wing rather 
distinctly white, a pale grey over the surface in the crossed by narrow white lines and two dark grey lines, 
one beyond the inner line, the other after the double whitish outer lines. From Colorado, with glemvoodi, but 
apparently a distinct species. 
T. toiteca Neum. (= deboma Drc., hemira D rc.) (79 a) is the Mexican representative of the velleda- 
group, generally greyer with darkened hindwings, the curved subterminal band distinctly darker than the 
hardly darkened median band; on the whole extremely variable in the white or rather grey ground-colour, 
the thorax also in the greyer specimens always conspicuously white. Dyar writes that he cannot see how it 
is to be separated from glenwoodi and also from hemira , so that they are probably synonyms. 
T. dyari sp. n. Draudt (81 b) is apparently a well defined rather invariable species which hitherto 
came only from Zacualpan in Mexico. Ground-colour brownish grey, not white, also the thorax and abdomen 
greyish-brown, median and subterminal areas narrower, both equally dark, the border-lines much less curved, 
particularly the inner one of the subterminal band almost straight and somewhat faded, not distinct; hindwing 
dark greyish-brown. Described from several $$; type in the Coll. Draudt. 
T. brevicrista Dyar (81 b) is the typical representative of the second group, in which the dark 
spatulate hairs are only on the metathorax as in the two following species. On the forewing the white predo¬ 
minates, the dark marks not heavy. New Mexico. 
T. vemerila Dyar (79 b, e). Forewing very light grey, almost white, crossed by grey lines which are 
traversed by the white veins, both the lines bordering on the not darkened median area are double, irrregularly 
waved, the subterminal line more spot-shaped. Hindwing shaded with grey, veins darker. Mexico (Guerrero, 
Tehuacan). 
T. mollifacta Dyar (79 b) is darker grey, the light markings of the velleda- group very feebly marked, 
with a white line at the base of the fringes on both wings. Mexico (Colima), taken in January.
