with a darker median band of the forewing, almost as dark as the marginal area and with brownish-grey 
hindwings. — The green, dorsally purple brown larva with white subdorsal lines lives on wild cherry (Prunus

antemedian band, the maculae are more distinctly surrounded by black, and there are four median lines which 
are very distinct particularly at the inner margin; the entire postmedian line is distally shaded with brown, 
and the undulate line is more dentate. Hindwing somewhat brownish at the margin. Texas.

Without a proboscis, but otherwise very similarly structured as Chamyris. Only 1 species: 
A. furcilla Grt. (52 b). Forewing brownish ochreous with a flesh-coloured tint and scantily strewn with furcilla.

marking bordered with black inside and forked like a Y above, from the inner margin obliquely towards the 
apex. Hindwing yellowish-brown. Alabama. 
49. Genus: Argyropasta limps. 
The genus contains but one small species with a stunted proboscis, the scaled thorax is tuftless, the 
abdomen tufted to the end. Forewing rather long and narrow with a rounded apex, without an areole, the

an areole and a normal Noctuid neuration. 
M, mirabilis Schs. (52 b). Forewing yellowish-white, red-brown in the centre almost to the inner margin, mirabilis. 
enclosing the large whitish reniform macula which is centred red-brown and surrounded by brown; posterior 
transverse line double; the narrow marginal area blackish brown. Hindwing yellowish brown with a central 
dot and a curved line behind it. Brazil (Rio de Janeiro). 
M, janeira Schs. (52 b) is the largest species with whitish forewings dusted with brown, with brown janeira. 
dentate transverse lines, the anterior line partly double, and with indistinct white-ringed maculae, the reni¬ 
form macula extended below into 2 points; undulate line double, exterior line thicker and deep black. Hind¬ 
wing light brown. Brazil. 
M. cyclopis Hmps. (52 b) is the smallest species with brownish ochreous forewings strewn with black cyclopis. 
and dusted with silvery purple, with black transverse lines, the posterior line double, filled with yellowish 
ochre, and with yellow maculae surrounded by black, the reniform macula centred with black; the crenu- 
latecl undulate line shaded with black inside. Hindwing greyish-brown. Panama. 
M. mollita Schs. (52 b). Forewing pinkish-yellow in the basal area, grey in the median area and at mollita. 
the inner margin as far as the distal margin, brown above it; both the transverse lines are double, brownish, 
the posterior line filled with whitish at the costal margin; maculae green, a greyish-brown median shadow 
dusted with green between them, a white line behind the reniform macula; undulate line white in its upper

51. Genus: ©rtholeuea Hmps.
