smoky-grey median shadow; the undulate line consists of small greyish-brown internerval spots; the large 
maculae are only feebly marked, the reniform macula as usual below dark pupilled. Hindwing light yellowish. 
Expanse of wings: 28 to 31 mm. Canada; Colorado. 
A. immaculata Morr. has monotonously red-brown forewings with almost extinct transverse lines 
and small indistinct black maculae, a faded black marginal band and red fringes. Hindwing dark brownish 
grey with red-brown veins. Expanse of wings: 37 mm. Colorado *). 
A. miastigma Dyar. Forewing straw-coloured, hued with pink, with slightly darker transverse lines 
and median shadow, and the maculae surrounded with dark, the reniform macula below pupilled wdtli a round 
black spot; the subterminal line irregularly undulate, light, with small blackish internerval spots, the most 
distinct of which is at the upper radial branch. Hindwing whitish, veins and margin grey. Mexico (Zacualpan). 
60. Genus: Atethmia Hbn. 
Slightly distinguished from the preceding genera; head and thorax are clad with hair and hair-like 
scales, the centre of the collar is raised somewhat ridge-shaped, and on the prothorax there is a keel-shaped 
tuft; the abdomen does not exhibit any tufts, and there are only hail at the base and on the sides. Beside 
some palearctic species (cf. Vol. Ill, p. 153) there also occurs a species in America: 
A. pampina Gn. A variable species with a produced, pointed apex of the forewing and a dentate margin 
which besides also varies in the intensity of the crerrulation, and there even occur specimens in which the distal 
margin is almost not dentate at all. Irr the type the forewing is orange, irrorated with purple red, the transverse 
lines bordered with a lighter yellowish colour, and large maculae, the dentate yellowish undulate line is proxi- 
mally shaded with purple red. Hindwing fiery red. — Other colours are exhibited by: pampinefla Strd. (= ab. 
1 Hmps.) being entirely suffused with purple pink with hardly any trace of yellow, with indistinct markings; 
■—- and brunneo-ochracea Strd. ( = ab. 2. Hmps.) with a light ochre-brownish ground-colour without orange 
or red irroration, which is only to be noticed on the hindwing and at the end of the abdomen. All these forms 
are wide-spread in Canada, to the south as far as Virginia and to the east as far as NewYork. -— Northern and 
western specimens are generally lighter, more yellow, so that the western race from Colorado was denominated: 
glenwoodi B. <£• Benj. in which the ground-colour is light yellow, hardly reddish, with feebler and more con¬ 
trasting markings, the markings inside filled up with a slightly darker colour; also the thorax and abdomen 
are light yellowish. 
61. Genus: «Iodiii Hbn. 
Separated by the preceding genus by a loose, not keel-shaped tuft on the prothorax. Only 1 species: 
P. rufago Hbn. (— honesta Wkr.) (29 i) in the shape and marking somewhat resembles the preceding. 
Forewing ochreous irrorated with red and a little strewn with blackish, the posterior transverse line marked 
by a double row of black vein dots. Canada to Texas and Florida. — The light brown larva with red-brown 
reticulations shows a broad yellowish-white lateral band. 
62. Genus: Braeliycosmia Hmps. 
Proboscis stunted, eyes small, reniform or bean-shaped; head and thorax only clad with hair, the 
prothorax exhibits a triangular tuft; all the rest as in the preceding. Only J species: 
B. digitalis Grt. (29 i). Forewing bright red-brown, except the median area irrorated with grey T , 
with straight whitish transverse lines and very small maculae. Hindwing red-brown. In the $ the transverse 
lines are stronger and of a pure white. Maine, New Hampshire, New York, Illinois. 
63. Genus: C'osmia 0. 
This genus being also known as Xanthia Hbn. contains, beside one species being also wide-spread in the 
palearctic region, two more species which are purely American. They differ from Atethmia and Jodia in the 
thorax being purely clad with hair and the collar not being keel-shaped, but the prothorax likewise exhibits 
a slightly keel-shaped tuft. (Cf. Vol. Ill, p. 153, and Vol. XI, p. 115). 
*) A. americana Morr. is the palearctic A. lota Linn, and is to be cancelled as being non-American.
