376 ERASTROIDES; VIA; PRODOSIA; LITHACODIA. By Dr. M. Dbatjdt. 
0. albiluna Hmps. (52 b). Forewing coppery red, with no other marking but the narrow white reni- 
form macula in the shape of a lunula surrounded by black, and the double posterior transverse line being 
filled with a pure white. Hinclwing light coppery brown. Panama. 
52. Genus : Erastroides Hmps. 
Small slender Noctuids quite similarly built as Ghamyris , but the forewing without the areole, the 
4 lower subcostal branches arising on a common stalk, the uppermost arising separately from the cell. 
E. emarginata Hmps. (52 b). Forewing reddish-ochre, spotted white before the centre and behind 
the centre of the costal margin, strewn with black in the basal and marginal areas, with blackish trans¬ 
verse lines, without maculae. Hindwing blackish-brown. Mexico, Panama. 
E. albiguttata Drc. (52 b). Foreving yellowish-green, all the 3 maculae white, the renifoi'm macula 
prolonged to the costal margin, with black transverse lines, a white triangular spot behind the exterior line 
at the inner margin, the undulate line shaded with black inside. Hindwing brownish, darker at the margin. 
Described from Peru. 
E. hermosilla Schs. (52 b) has light olive green forewings strewn with black excepting the marginal 
area, with double transverse lines connected by black on the submedian fold, the posterior line filled with 
white; median area dusted with red-brown, with a white stripe on the median vein, expanded at both its 
ends and confluent outside with the reniform macula which is surrounded with whitish; the white undulate 
line is marked black inside, with an indistinct larger spot below the costal margin. Hindwing greyish-brown. 
Brazil, Paraguay. 
E. propera Grt. (52 c). Forewing dark brown, dusted with grey, reddish ochreous in the marginal area; 
the anterior transverse line is indistinct, bordered with yellowish inside, the posterior line double, filled 
with white, the reniform macula centred with brown and surrounded with white, the whitish undulate line 
finely dentated. Hindwing brown. Arizona. 
53. Genus: Via Dyar. 
Proboscis developed, palpi slender, scaled below, the frons with a rounded conical projection; thorax 
and abdomen tuftless. Forewing without the areole, the uppermost and lowest subcostal branches free, the 
latter from the upper cell-angle, the 3 middle branches on a common stalk. Only 1 species: 
V. vindicai Dyar (52 c). Forewing lustrous purple brown, with yellowish-white transverse lines, the 
anterior one distinct, curved, the posterior one feeble, almost extinct in the centre. Hindwing bronze black. 
A very small insect with an expanse of but 10 mm. Panama. 
54. Genus: Erodosia Dyar. 
Separated from the preceding genus by the smooth frons, the last palpal joint being longer, one tuft 
each on the 1st and 3rd abdominal segments and an areole on the forewing. Likewise only one very small 
species: 
P. mycha Dyar (52 c). The basal three fifths of the forewing yellowish-brown (probably green in the 
fresh specimens), purple black behind it, the two colours separated by a whitish line which is twice den¬ 
tate below the costal margin; maculae absent, undulate line indented in the middle, more or less distinct. 
Hinclwing blackish brownish-grey. Panama. 
55. Genus: Eitliaeodia Hbn. 
This genus contains a large number of small Noctuids of a most varied exterior, mostly of a rather 
slender structure with a developed proboscis, erect palpi, a smooth frons and scaled thorax, prothorax tuftless, 
mesothorax with two tufts and metathorax with a loose tuft, a series of tufts on the dorsum of the first 
abdominal segments, those on the 3rd and 4th being especially large. Forewing with an areole and a regular 
neuration, hindwing with a strongly developed middle radial branch. Larvae, as far as they are known, 
without the first prolegs, the second being rudimentary. 
L. synochitis G. & R. (52 c). Forewing white, purple brown postmedianly and at the costal margin, 
dusted with olive green in the median area and in some places behind it, with indistinct transverse lines filled 
with white, the maculae surrounded by white; undulate line indistinct white, some black streaks before it below 
the costal margin, behind the line we see the apex dusted with blackish. Hindwing brownish, darker at the 
margin. Canada to Texas. 
L. phya Drc. The purple grey forewing strewn with black exhibits a large white spot in the basal 
area in the inner-marginal half, with black transverse lines, the posterior one double, filled with white and 
reddish, and brownish-white maculae, the reniform macula large, quadrangular, white, strewn with brown in 
the centre; instead of the undulate line there are small black sagittate spots with red streaks from there to 
the margin. Hindwing brown. Mexico.
