62 Lord Walsingham on Western 
Mesoro.ia, gen. n. 
(mecondAtos = grizzled.) 
Tyee, gf Mesopolia inconspicua, Wlsm. 
Antenne, & strongly bipectinate (3-4), the pectinations biciliate, 
basal joint tufted in front. Labial palpi slender, short, porrect, 
not reaching beyond the head. Maxillary palpi and haustellum 
obsolete. Head thickly scaled, but moderately smooth. Thorax 
smooth. Forewings elongate ovate, costa evenly arched, apex 
rounded, termen oblique, tornus rounded. Vewration, 12 veins; 
7 and 8 stalked, 8 to below the apex, 5 somewhat bent over and 
approximate to 4 at its base ; an internal vein forms a supple- 
mentary cell by arising from slightly below 7 + 8 and running to 
between 10 and 11, and a stalked internal vein from between 11 
and the base emits branches to either side of 5. Hindwings as 
broad as the forewings, ovate, costa slightly convex. Neuration, 
8 veins all separate; 6 and 7 closely approximate at base, 5 
approximated to 4,a stalked internal vein emits its branches to 
either side of 5. [Legs and abdomen missing. | 
This genus appears to be allied to Narycia, Stph. 
(Xysmatodoma, Z.)}, but differs in the forra of the antennw 
and in neuration. It has very much the appearance of 
Psilothrix dardoiniella, Mill., but is somewhat larger and 
there are no veins missing as in that species. Nothing is 
known at present of its habits, but the larva is probably 
a case-bearer. 
Mesopolia inconspicua, sp.n. (PI. IL., fig, 12.) 
Antenne ashy-grey. Palpi dark fuscous. Head and thorax 
ashy-grey, the latter shaded with fuscous anteriorly, Lorewinys 
ashy-grey with numerous short transverse striz and spot-like 
groups of brownish fuscous scales—these form a rather conspicu- 
ous spot below the costa near the base, another beyond and below 
it extending on both sides of the fold, and a third about the 
middle of the wing, there is also a slight shade about the upper 
angle of the cell; the other spots are more or less distributed over 
the wing surface; cilia ashy-grey with a slight parting shade 
along their middle. Exp. al., 23mm. Hindwings pale brownish, 
cilia slightly paler. [Abdomen and hindlegs missing. |
