0. albicostata Drc. is likewise very similar to the preceding ones, larger, more yellowish, with a dark, 
not white-centred reniform macula, undulate line yellowish, outside shaded with blackish-brown. Arizona 
and Mexico. 
0. albocostaliata Pack., described as Acidalia, is very similar to albicosfata , the white costal-marginal 
stripe is much broader, the discal dot very small, a round dot, not a lunula, the undulate line much more 
indistinct. Atlantic States. 
0. eostalis Dyar. (50 h) is grey with a reddish tint and a straight broad dingy yellowish white stripe 
leaving the extreme costa dark; transverse lines straight, very fine whitish, the median area between them 
shaded with blackish, with a blackish discal streak; undulate line whitish, curved from the costal margin to 
the centre of the distal margin, below it sharply dentate. Hindwing the same. Mexico (Misantla, Orizaba). 
0. diionocraspis Hmps. Forewing red-brown, at the margin tinted with grey, with a silvery white 
costal-marginal stripe, in the basal area dusted with fiery red; transverse lines faded, anterior line dark brown, 
posterior line finely edged with white, between both a small dark discal spot; undulate line indistinct, grey, 
outside with black dots. Hindwing the same. Expanse of wings: 22 mm. Venezuela. 
0, doto Schs. (50 h). The basal half of the forewing is purple brown, outside bordered by the yellowish- 
white reniform macula and posterior transverse line, behind it blackish-brown, before the fine irregular grey 
undulate line shaded with purple, in the marginal area purple grey; the light anterior transverse line is puncti- 
forrn and does not quite reach to the inner margin. Hindwing the same. Surinam. 
24. Genus; Ectrogatlua Hmps. 
Distinguished from the preceding genus by the falciformly curved apex of the forewing with a deep 
indentation below it and an angle on the lowest radial branch. 
E. himerata Wkr. (50 h). Forewing light reddish-brown, strewn darker, particularly at the costal 
margin, with fine blackish-brown transverse lines and the reniform macula thickly surrounded with blackish- 
brown; marginal area darkened brown, on the hindwing more red-brown. Brazil (Amazons). 
25. Genus: (Jobuhnllin Wkr. 
Tins extensive genus, known also as Tripuclia , contains the smallest Noctuids, the exterior and be¬ 
haviour of which resemble the Micro- genus Choreutis. They are small, broad-winged lepidoptera, with fre¬ 
quently orange hindwings, a well developed proboscis, erect palpi of medium .length, smoothly scaled body 
with double tuftlets on the metathorax and a flat tuft on the metathorax; the abdomen likewise exhibits a 
row of tufts on the first rings, the largest on the 2nd ring. On the forewing the 3 middle subcostal branches 
are stalked, the upper and lower ones rising freely, the accessory cell is absent ; the middle radial of the hindwing 
is fully developed and comes forth near the lower cell-angle. 
C. hippotes Drc. (50 h) has purple grey forewings, with a reddish-brown tint towards the margin, with 
a broad, deep velvety brown median area, the latter at the costal margin somewhat narrower, bordered by 
fine black, white-edged lines, with a small black discal spot surrounded by white; a light undulate line is hardly 
visible. Hindwing brownish-grey with a copper tint. Mexico (Guerrero, Zacualpan). 
€. rustics Dyar (50 h) is very similar to hippotes , smaller, brownish-grey with a slight pink tint, the 
dark red-brown median area towards the base not so distinctly defined, before it lead-coloured irroration; the 
reniform macula is a small dark brown spot, before the irregularly dentate white undulate line some lead- 
coloured shading. Hindwing lighter greyish-white. Mexico (Cuernavaca). 
C. ipilla Dyar (50 i) is likewise similar, as large as hippotes , much lighter, yellowish-grey, the median 
area pinkish-brown, inwardly faded, only the exterior white border-line distinct, the interior one quite indistinct; 
undulate line distinct, blackish, irregularly dentate. Mexico (Cuernavaca). 
C, damozela Dyar (50 i). Forewing dark silvery grey, with 2 oblique fine brownish antemedian lines, 
a broad blackish median transverse line, in a concavity of which the reniform macula is situate; in the post¬ 
median area there are several brownish faded dentate lines, before the apex a black trapezoid spot, and before 
the centre of the distal margin a black triangular spot. Hindwing brownish-grey. Mexico (Tehuacan). 
C. rnurma Dyar (50 i) is very similar to damozela, the basal half is lighter whitish-grey, bordered by a 
fine black line with a brown parallel band from the inner margin to the median, the posterior transverse line 
as in damozela enclosing the reniform macula; before the dark undulate subterminal line there is only a black 
costal-marginal spot. Hindwing lighter. Mexico (Tabasco).
