white, with a whitish strigiform spot in it sub terminally behind the cell. Hindwing brownish, on the veins 
and margin darkened. From Colombia (Quindiu-Pass) and Bolivia (Cuesta de Cillutincara), captured by Fassl; 
the latter specimen exhibits above the absent coniform macula a long silvery white streak dividing the blackish- 
brown ground almost into two parts: — - albisecta form. nov. (18 c); at least this streak is not mentioned in the 
description of fluminalis, it may possibly be another species. 
19. Genus: Hydroeciodes limps. 
Rather closely allied to the preceding genus and above all distinguished by the long ciliated eyes; the 
frons exhibits the same rounded convexity with a horny plate below it. The thorax is covered with scales abun¬ 
dantly intermixed with hair, and the collar is in the centre somewhat keel-shaped; on the vertex the head exhibits 
a large hair-tuft; all the rest agrees with the preceding genus. To the half a dozen of species enumerated by 
Hampson in his Catalogue there have in the meantime numerous, mostly extraordinarily similar and not easily 
discernible species from Mexico been added, so that the number of forms known to-day has increased to 35. 
Sect. I: An t e nnae with long double co m b s. 
H. xanthina Hmps. (18 e). Forewing yellow, strewn with brownish-red, with very fine transverse 
lines, the anterior line double, the posterior single; coniform macula, ring-macula, and reniform macula finely 
encircled with brown, the latter below distallyvery little darkened with ferruginous yellow, with a hardly traceable 
whitish dot in the lower cell-angle; the dark median shade extends in the cell to somewhat below the discal 
fold, then it turns sharply towards the lower cell-angle, from where it bends in an acute angle obliquely inwards 
to the centre of the proximal margin; undulate line fine, brown, in the upper half somewhat thicker than below; 
marginal area, particularly in the $, and especially behind the cell somewhat darkened. Hindwing in the 
diaphanous whitish strewn with brownish on the veins and margin darker, in the $ quite brownish-grey with 
somewhat more yellowish fringes. Mexico. 
H. mormon Dyar. Body dark brown. Forewing in the ground ochreous, spotted orange, but so 
densely dusted dark brown, that only the macular filling and the subterminal area remain yellow; transverse 
lines fine, blackish; the proximal line cuts the area of the orange coniform macula abruptly, it is angular on the 
inner-marginal vein, the distal line dentate on the veins; the coniform macula is longitudinally parted by a 
dark line; ring-macula round, pxqhlled ochreous, the reniform macula is above proximally and in the centre 
distally spotted orange, with an oblique white spot in the lower inner angle, distally with 5 roundish, small 
white spots; the subterminal area before and behind the shaded undulate line is spotted orange-ochreous, the 
marginal area is darker. Hindwing in the disc ochreous, the discal spot, veins and marginal area shaded with 
blackish. Expanse of wings: 31 mm. Mexico (Zacualpan) in January. 
H. pexa Schs. (18 c). Forewing orange, strewn and dusted with red-brown, the least before the anterior 
transverse line below the cell and postmedianly except the costal part, and with single, undulate, not dentate 
transverse lines; coniform macula short, yellow, strewn with red and surrounded with brown like the two upper 
maculae, the ring-macula round, the reniform macula all round spotted white, between both a median line 
being angular on the median; undulate line in the centre distally bent. Hind wing of a monotonous brown. 
Mexico. 
H. pexinella Dyar (18 e) is smaller than the preceding with narrower reddish yellow spots in the 
sudterminal area. Forewing more extensively brown, only in the maculae and subterminal area yellowish- 
reddish, the posterior transverse line more distinctly dentate. Mexico (Zacualpan) in August. 
H. ruxis Dyar (18 e) is still somewhat smaller and quite monotonously brown without any yellowish 
red spotting; the proximal transverse line is almost rectangularly flawed on the median; the reniform macula 
distally with a large, crescentiform, white spot, above it a dot and below it 3 situate in a triangle; the sub¬ 
terminal area is hardly lighter. Hindwing somewhat lighter greyish-brown. Mexico (Zacualpan) in September. 
H. exagitans Dyar. In this species the hairing of the palpi in front is longer than generally. Thorax 
dark brown, abdomen blackish with a light anal tuft. Forewing monotonously brown with somewhat lighter 
ante- and postmedian bands and maculae with a slightly yellowish tint and finely bordered with black; marginal 
area slightly darker; ring-macula small, round, reniform macula likewise small, pupilled blackish; the distal 
transverse line is dentate, also the undulate line though somewhat less. Hindwing grey, in the disc lighter with 
a feeble discal spot. Expanse of wings: 27 mm. Mexico (City) in June. 
H. aspasta Dyar (18 e). Forewing very light yellowish greyish-brown with large, somewhat lighter 
maculae finely encircled with brown; transverse lines single, dark, almost straight, on the inner-marginal vein 
dentate, between them a hardly darker median shade; the marginal area is somewhat darker, before it the 
indistinctly lighter, irregular undulate line. Hindwing diaphanous light grey with a dark discal dot and marginal 
line. Mexico (Chiapas, Tabasco) in May. 
H. mendicosa Dyar (18 e, f). Light loam-coloured yellowish, dusted with brownish-grey, except 
the filling of the maculae and the subterminal area, the veins in the distal half strewn with whitish; the anterior
