NUDARIA +, Haworru. 
This is another curious genus, distinguished by its subhyaline rounded wings, which are present in both sexes, 
slender setaceous antennee, slender recurved palpi, and long spiral tongue; the postcostal vein is peculiar, on account 
of its emitting three branches of equal length close to the tip of the fore wings. The caterpillars are clothed with 
very long hairs. They do not form portable cases ; and the chrysalis is slender and silken, with the hairs of the

caterpillar interwoven. As suggested by Curtis and Boisduval, the genus seems to be nearly related to the 

Lithostidee.

7, fig. 80. 
This species measures from 9 to 1] lines in the expanse of the fore wings, which are of a very pale, whitish 
clay-colour, and iridescent, with a short dark stripe near the base, two slender arched, brown fasciz across the 
wings (one before and the other beyond the middle) and with a dusky central dot and an indistinct dark wave 
parallel to the outer margin. The hind wings are without spots. The caterpillar (fig. 20*) is dark green, with 
a luteous stripe down the back. It feeds on lichens, The moth appears in July and August. It occurs in 
yarious parts of the country, and is by no means rare. 

SPECIES 2.—NUDARIA HEMEROBIA. Prats XVI., Fie. 18. 
Synonvmes.— Bombyx hemerobia, Hiibner, pl. 17, fig. 65. Stephens ; Curtis, Wood, Ind. Ent. pl. 7 fig. 87. (Nudaria h.) 
This species, regarded by some authors as a variety of the preceding, differs from it in being of a smaller 
size, with the wings colourless and iridescent, without any spots or markings ; the veins being slightly luteous, 
and the fringe yellowish. Specimens agreeing with this description have been reared by different collectors, 
as well as taken at large; but the species is rare. 

SPECIES 3.—NUDARIA SENEX. Puate XVI., Fic. 20. 
Svnonymes.—Bombya senex, Hiibner; Stephens (Nudaria s.) ; Nudaria rotunda (The round-winged Muslin), Haworth. 
Curtis ; Wood, Ind. Ent., pl. 7, fig. 88. Paidia senex, Hiibner, Verz. bek. Schm. 
This species measures about } of an inch in the expanse of the fore wings, which are comparatively much 
shorter than in the two preceding species. The male has the joints of the antenne bisetose: the wings are 
of a dull luteous, ochre colour. The anterior pair with numerous brown spots and dots, mostly placed upon 
the veins; some of them forming transverse curved lines ; the fringe is spotted with brown; the hind wings 
with a dusky central lunule, and several submarginal faint spots. This species frequents marshy places, having 
been found (but rarely) in Battersea fields and Whittlesea-mere in July.
