and narrowed as it attains the dorsal margin ; the base of the wing between this marking 
and the thorax is somewhat mottled with the same shades as compose the fascia ; the second 
fascia originates in a geminated oblique costal streak scarcely beyond the middle, which just 
reaches to the next costal streak beyond it, thence diverging at an angle to the apical margin, 
of which it covers the lower fourth with the anal angle ; this fascia has an excrescence on its 
inner edge projecting along the cell ; and below this excrescence is a branch running to the 
doi'sal margin, which branch also has a projecting excrescence on its inner edge. Towards 
the apex are three geminated costal streaks ; the first, after touching the outer angle of the 
fascia as described, converges, with the other two, towards the middle of the apical margin. 
The above-described markings leave the ferruginous ground-colour of the wings most con- 
spicuous, in a wide central band, a triangular dorsal spot before the anal angle, and an ovate 
patch, projecting obliquely inwards, rising from below the middle of the apical margin. The 
costa is shaded with fuscous between the streaks ; and there is a narrow fuscous line along the 
apical margin. The markings and general appearance of this insect remind one strongly of 
those of a Sericoris. 1 , 1 ? . Expanse of wings 17 millims.

Exartema punctanum. (Plate LXVIII. fig. 8.) 
Head brown, tufted above; palpi whitish, the second joint thickly clothed with long 
scales projecting below the exposed apical joint, which is fuscous ; antennae scarcely pu- 
bescent in the male. Fore wings whitish fawn-colour blotched with olivaceous fuscous ; an 
angulated blotch at the base of the dorsal margin, another on the middle of the costa, another 
rather darker covering the apex and apical margin, and two paler olivaceous blotches, one on 
the middle of the dorsal margin, another before the anal angle ; also some abbreviated streaks 
along the costa j the space between the blotches contains some very sublustrous leaden-grey 
lines and bands ; a slender pale line, followed by a Avider fuscous line, runs along the apical 
margin at the base of the cilia ; a fuscous spot lies within the end of the cell. Hind wings 
brownish, darker towards the margin ; cilia whitish, with a dark line along them as in the 
fore wings. 1 cJ, 2 5 . Expanse of wings 17 millims.

This species is nearly allied to Exartema inornatanum, Clem., which. Prof. Fernald 
informs me, is probably the E. quadrifidimi of Zeller (Verb. z.-b. Ges. Wien, xxv. p. 268) ; 
but the markings are more defined, and the spot at the end of the cell constitutes a good distin- 
guishing character.
