the antemedian transverse line is indistinctly double, intertilled with white. A brown median line is indicated. 
The narrow white reniform stigma has a black dot at top and bottom. Also the postmedian line is double with 
white interfilling. Subterminal line white, dusted with blackish along the inner edge. The whitish hindwings 
are suffused with reddish brown with white subterminal and a red spot beyond on vein 2. Canada and the 
United States, southwards to Texas, westwards to Nebraska. Kansas and Colorado. 
M. angustipennis Schs. (55 e). Head and collar grey, the latter with fuscous edge. Thorax fuscous angusli-pen- 
with blackish bands. Forewings grey-white peppered with brown. Costa, inner margin and margin suffused 
with red-brown, with semi-transparent whitish streaks through the cell and the submedian. The anterior 
transverse line only distinct at costa and inner margin. A black, white outlined dot in upper angle of cell. 
Postmedian double at costa, then obsolescent except for a blackish spot on inner margin. Hindwings whitish, 
dusted with pale brown. Brazil (Castro). 
Mo inficita Wkr. (= histrio Grt.). The violaceous grey forewings are suffused with brown; there is fus- inficila. 
cons dusting anterior to the blackish antemedian. Median area with white streaks, in the upper angle of cell 
a black triangular mark edged with white. Postmedian line indistinct, double, intertilled with white, inter¬ 
rupted. Subterminal line white and dentate, with a small brown band inwardly at apex. Hindwings white, 
dusted with brown. Wing expanse: 26—34 mm. A similar distribution to basalis. - f. minus Dyar is smaller minus. 
than name type, the pale patches in discal area, reniform stigma and anal area are more prominent, whitish. 
Wing expanse: IS—22 mm. Texas and Arizona. 
4. Genus: Aon Neum. 
Distinguishable by the absence of the proboscis; 3rd segment of palpi projecting. Antennae with long 
pectinations. Thorax with only a posterior open tuft. Abdomen without tufts. Forewings elongate and narrow. 
On hindwings veins 3 and 4 stalked. Only 1 species: 
A. noctuiformis Neum. (55 d). Forewings grey with brownish striations and sparsely peppered with nociuiformis. 
black; a white streak through the cell, almost to margin, the lower marginal half with fuscous tone. Transverse 
lines absent, a black dot at end of cell. Hindwings white, dusted with brown towards the margin and with 
a small black discal spot. Texas. 
5. Genus: I*a eete&Hbn. 
Proboscis developed, palpi moderately long, the 2nd segment with hairs above and below. Antennae 
of d bipectinate. Thorax with only an anterior open tuft. Abdomen devoid of tufts. Wings of the american 
species without special feature. Numerous, partly very similar, mostly brown species, often reminding one of 
the Phytometrinae Genus Abrostola in their markings. 
Type: P. pygmaea Hbn. 
P. devincta Wkr. ( = peculiaris Btlr ., nrurina Drc.) (55 d). The <$ has a somewhat lobiform process at devincta. 
anal angle of forewings. Reddish brown, somewhat suffused in basal area with violet-blackish, similarly at 
costa behind the postmedian and in centre of margin, with an oblique white-grey streak from apex expanding 
to centre of inner margin. Transverse lines rather indistinct, postmedian double, red-brown, obtusely angulated 
on nervure 6; a white dot in centre of cell and at close of cell 2 fuscous dots; black subterminal streaks above 
and below vein 6. Hindwings blackish brown, paler towards the base. From Mexico to Brazil (Amazonas and 
San Paulo). Common. 
P. fovifera Hmps. closely resembles the preceding, but the anal angle of forewings is not extended; fovifera. 
in the however the upper angle of cell of hindwings is prolonged and there is a triangular somewhat obliquely 
ribbed cavity between the widely diverging veins 6 and 7. Forewings fuscous in basal area and very obliquely 
along the costa to apex, pale greenish below cell and at inner margin. Marginal half inclined to grey-white, 
brown at margin and toned with greenish at costa and inner margin. Markings otherwise as in devincta. In 
the $ the entire postmedian area is of green hue. Wing expanse: 26 mm. From Panama to French Guiana. 
P. oculatrix Gn. (55 d). The grey forewings suffused with brown, along the costa with a wide reddish oculairix. 
streak, white at base, with a triangular olive-greenish area above the inner margin, distally the antemedian 
that is only discernible in the inner marginal half; a large black double arch follows. Hindwings brownish. 
Canada and the United States. Larva pale green, head and underside somewhat bluish, the 5th segment is 
the stoutest, tapering off posteriorly; body irregularly spotted with white and with fine hairs. The larva clings 
to the underside of the leaf and eats irregularly shaped holes into it. It pupates in the earth in August and 
emerges in June of the following year. 
P. semicircularis Hmps. (55 d) is very similar but smaller, it is without the reddish costal streak, on scmicircula- 
the other hand the greenish triangular area is prolonged into a wider oblique band extending to costa. Hind- r >s. 
wings distinctly darker brown. From Trinidad (Caparo). 
P. chrysoplaga Drc. (55 d) has the same style of markings as the two preceding species. Head pure chrysoplaga. 
white, body red-brown admixed with white. Forewings grey-white, fuscous at costa, otherwise partially flesh-
