and a large number of species occur especially in Ceylon and the Sunda Is.; more than a dozen forms have been 
reported from Ceylon alone. Only two American species occur in the genus as it is comprehended here, a very 
tiny one the smallness of which is only excelled by Epijryropidae, and a larger one which is rather unicoloured 
sooty blackish brown. — Palpi erect, reaching the frons. Wings broad. Vein 5 of forewing below the upper cell- 
angle, somewhat higher than in the preceding genus, all the other veins the same. Hindwing typically with 
small points at veins 7 and 4. Vein 5 from the middle of the cross-vein, 6 and 7 from the upper cell-angle or 
on a short stalk. with a fold and hair-pencil at the inner margin beneath. Type: theclata Gn. from Africa 
and India. Dirades is one of the few genera occurring in several faunae. 
D. infans Warr. (172 e). Wings lilac grey, dusted darker. Median band of forewing brownish, thickly infans. 
edged with dark brown. Interior line at %, uniformly bent, the exterior line from % costal margin, outward 
as far as vein 6, then vertical to vein 4, bent inward in the submedian fold. A dark shadow behind it at the 
costal margin and anal angle. Black dots before the margin. Hindwing similar. Both the lines bent, marginal 
area silvery grey, a black dot before the lower dent. Inner margin of forewing excurved at the base, hollow 
behind the middle. Hindwing with a dent at vein 4, smaller ones at 6 and 7. $ 12 mm. Jamaica. 
D. erebata Warr. (172 e) has the neuration of Dirades, but it looks quite different. Brownish black. A erebata. 
black line at the cross-vein of the forewing, a white spot before it. Exterior line pale, edged darker inside, from 
4 / 5 costal margin somewhat outward, from veins 6—2 vertical, then inward almost to the anal angle. The hind¬ 
wing has a dark bent exterior line, with rusty brown scales behind it and pale spots between the veins. Inner 
margin and fold white, the hair-pencil brownish ochreous. q 23 mm. Peru.

This genus has also been differently defined by the various authors. It occurs especially in the Indo- 
Australian Region, from where 16 forms are known; only 1 species is known from Africa and 6 from America. 
In the Old World, however, its distribution is enormous, extending even to the remote South-Sea Islands, and 
one form ( fasciaria Leech ) is said to reach also the palaearctic region in Corea. All the species are small. - 
Palpi thin, obliquely raised, antennae flattened. Porewing broad, entirely margined. Veins 5, 6 and 7 close 
together or 6 -j- 7 on a short stalk, 8 + 9 and 10 + 11 stalked. Hindwing concave at the costal margin in 
the middle, with a hair-tuft at the base and apex. Distal margin somewhat dentate at veins 7, 6 and 4, $ with 
a fold and hair-pencil at the inner margin. Neuration of hindwing normal. Type: misaria Wkr. from India. 
Nearly all the American species resemble dilacerata Gn. 
G. dilacerata Gn. (172 e). Forewing greyish yellow, more densely dusted dark in the anterior half, dilacerata. 
with transverse rows of dark brown spots. Hindwing blackish, whitish at the apex, yellowish at the inner 
margin. Three black spots at the apex. Short dents at veins 7, 6 and 4. 20 mm. Cayenne. 
G. biocellata Warr. (172 e). Forewing dull greyish brown, strewn with dark. The only marking consists biocellata. 
of 3 small black spots below the apex, the margin is narrowly brown from the apex to vein 5. Hindwing blackish. 
Interior line near the base, black, bent. Exterior line double, roundly bent forward in the centre of the wing, 
with black spots inside, edged light outside. Two white dots at the cross-vein. Black lunae at the dents. A 
hyaline spot at the base with black marginal streaks. $ 16 18 mm. Peru, Bolivia. 
G. cassata Warr. Reddish grey, more brownish ochreous towards the apex. Costal-marginal area ex- cassata. 
cepting the apex as far as the middle of the cell grey with brown spots. From 4 / 5 costal margin a grey undulate 
line extends vertically to vein 6, where it is interrupted, at % inner margin as a double black line filled with 
brown. Paler behind it, blackish brown only at the anal angle. Black dots before the margin. On the hind¬ 
wing the apical area above vein 6 and the inner margin are pale straw-coloured. The two lines angled in the 
middle, the interior one black, the other one light brown. A brownish ochreous spot at the upper cell-angle. 
Brown and blackish brown scales from the costal margin to vein 2. Black lunae at the margin from veins 7 
to 4, brown scales before them. $ 21 mm. Mexico. 
G. ochripennis Warr. Greyish brown, brownish ochreous at the apex, costal margin spotted light and ochripennis. 
dark. A double grey undulate line from % costal margin to the cell, then interrupted and as a double brown 
streak at the inner margin, the sides of it, however, not parallel as in cassata. A short greyish yellow band behind 
it. Anal angle dark grey. Hindwing marked as in cassata, but the light places ochreous, somewhat grey. A 
spot between veins 4 and 5 before the margin, a small cellular spot and one at the costal margin before the apex 
purely yellow. $ 24 mm. Mexico. 
G. latonaria Schs. Wings rusty brown. Forewing broadly dark grey at the costal margin. Interior hue latonaria. 
fine brown, extra-angular at vein 4, forked at vein 2 and enclosing a broad dark spot at the inner margin. Ex¬ 
terior line dark brown, excurved, united with the interior line below vein 2. Blackish dusting at the margin 
and before it. A small black spot at the apex, and one below it. Hindwing scantily dusted with black, the lines
