peated in smoky-brown. Expanse 23 mm.

Allied to plumbosignalis Fern., but readily distinguished by its 
bright yellow secondaries. 
DIASEMIA? FENESTRALIS sp. nov. (PI. I, Fig. 11). 
Antennae of @ annulate; labial palpi long, beak-like, 3rd joint slightly bent 
downward at extremity; maxillary palpi tufted with scales at extremity, front 
rounded, not prominent; primaries hollowed out below apex and again above 
anal angle, forming a rather prominent bulge between veins 2 and 5; secon- 
daries slightly excised below apex; head, thorax and primaries light brown, 
latter with the median area more or less broken up into semihyaline white 
patches, defined by the dark veins and cross lines; costa and terminal area 
brown; wing crossed by three fine brown lines, the first subbasal only distinct 
in median area where it is preceded by a white blotch, the second antemedial, 
oblique outwardly to cubitus, then parallel to outer margin, the third postmedial, 
outwardly oblique to vein 7 then rather irregularly waved and semi-parallel to 
outer margin; orbicular occasionally present as a brown dot encircled with 
whitish; reniform a brown lunate mark; beyond the third line the intravenular 
spaces contain a row of whitish blotches separated by the brown veins and be- 
tween veins 3 and 5, beyond this row, are two more similar blotches with an 
occasional third one between veins 2 and 3; fringes black brown, white in the 
excisions. Secondaries hyaline white with faint trace of a dotted postmedian 
line and a slightly broken terminal dark line; fringes smoky in costal half, 
whitish towards anal angle. Beneath whitish hyaline, primaries with an irregu- 
lar dark smoky border, a dark reniform and a dark dash on costa at inception 
of 3rd cross line of upper side, secondaries with a rather prominent dark costal 
blotch %4 from apex and a smaller one near base; a dotted dark terminal line 
and traces of the subterminal line of upper-side. Expanse ¢ 23 mm.; 9 28 mm.

According to Hampson’s tables the species would fit equally well 
into half a dozen genera; we place it in Diasemia on the strength of 
the annulate ¢ antennae and the excised apex of secondaries; the shape 
of the primaries is much as in oblectalis Hulst, but the frontal struc 
ture would preclude association with this species. 
Gyros (Monocona) ATRIPENNALIs sp. nov. (PI. I, Fig. 12). 
Palpi, head and thorax covered with long greenish white hair; fore and 
mid-legs white, hind legs black; primaries blackish with a considerable deep 
purplish-red tinge; basal half of wing defined outwardly (at times quite promi- 
nently) by a curved dark t. a. line just beyond which a black dash in the cell
