EXAETEMA. 37 



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 j this fascia has an excrescence on its 

 inner edge projecting along the cell ; and below this excrescence is a branch running to the 

 dorsal 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 c?; 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 ; the space between the blotches contains some very sublustrous leaden-grey 

 lines and bands ; a slender pale line, followed by a wider 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 c?, 2 $ . Expanse of wings 17 millims.

This species is nearly allied to Exartema inornatanum, Clem., which. Prof. Fernald 

 informs me, is probably the E. quadrifidum 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.
