Additions. 
The following genera and species published while the work was in the press could no more be inserted 
in the table of genera and the text. 
Genus: Xeiraga Mats. 
It is said to resemble Birthama (p. 688) in the neuration; antenna of $ bipectinated to the apex; costal 
margin of forewing almost straight as far as apex, distal margin almost vertical on the costal margin from 
the apex to vein 6. 
N. baibarana Mats. <J. Eorewing dark brown, a broad area below the cell and a broad stripe before baibarana. 
the margin brownish ochreous, intermixed with some dark scales, both being almost rectangularly bent. Margin 
paler between the veins. Hindwing blackish. Body dark grey, tufts on thorax and abdomen darker, under 
surface and legs yellowish. Expanse of wings: 18 mm. Formosa, in July. 
Genus: Chibiraga Mats. 
Neuration and antennae the same as in Idonauton (p. 702), but the stalk of 7 -f- (8 -j- 9) shorter than 
half the stalk of 8 -j- 9. Palpi straightly porrect, projecting beyond the frontal tuft. Antenna of <$ bipectinated 
in the basal two thirds. Posterior tibiae only with terminal spurs. 
N. nantonis Mats. S- Forewing pale greyish-brown, reddish yellowish-brown at the costal and distal nantonis. 
margins, with a postmedian blackish band which is slightly incurved and terminates near the inner angle, 
bordered on the inner side with blackish scales, cross-vein blackish. Hindwing yellowish-brown, darkened 
towards the tornus. Under surface paler, costal margin brownish. Expanse of wings: 28 mm. Formosa. 
Genus: Elagodopsis Mats. 
Allied to Nagoda (p. 674), antenna of plain, palpus upcurved to the vertex. Margin of hindwing 
straighter; posterior tibia with two pair of long spurs. 
N. shirakiana Mats. Forewing blackish-grey, diaphanous hyaline, with broad blackish margins, shirakiana. 
a small snow-white dot in the centre of the suture, two similar small white spots below it on lb. Hindwing 
hyaline, margins blackish, veins yellowish. Expanse of wings: 20 mm. Formosa, in March. 
Genus: Uliltsilllllirides nom. nov. ( Hyphormoides Mats. 1931, nec Strand 1914) 
Separated from Hyphorma (p. 690) by the $ antenna being bipectinated to the tip, the porrect palpus 
as long as twice the length of the head, the terminal joint being much shorter than the second. 7—9 of fore¬ 
wing stalked, 10 from the upper cell-angle, 6 -j- 7 of hindwing on a long stalk. 
M. okinawanus Mats. <$. Forewing yellowish-grey, with blackish, slanting, parallel postmedian and okina- 
submarginal bands, the former somewhat broader; distal margin somewhat darker. Hindwing of the ground¬ 
colour of the forewing. Under surface somewhat lighter. Expanse of wings: 24 mm. Okinawa. 
Genus: Coutlieyloides Mats. 
Structurally similar to Contheyla (p. 708), but forewing longer, distal margin almost vertical on the 
costal margin from the apex to vein 6; 6 of hindwing distantly separated from 7. The habitus of the species 
resembles that of Cheromettia-Belippa (p. 673—74). 
C. boninensis Mats. <$. Forewing reddish yellowish-brown, blackish-brown at the costal margin, boninensis. 
greyish-brown in the marginal quarter, with a blackish antemedian transverse line bifurcating at the inner 
margin, a similar median line undulated below the cell, and an undulated postmedian line which ends at the 
tornus. Costal margin with some black dots before the apex. Cross-vein with a small yellowish-brown dot. 
Hindwing yellowish-broVn, with blackish marginal dots. Under surface blackish-grey, apical angle reddish- 
yellow, with an oblique blackish costal-marginal spot before the apex, the distal margin with blackish dots. 
Expanse of wings: 34 mm. Bonin Is. 
Genus: Demonarosa Mats. 
Allied to Narosa (p. 675), but 6 and 7 of hindwing distantly separated, the middle part of the cross¬ 
vein oblique towards the inner margin, forming an obtuse angle with the upper part, the lower part almost 
parallel to vein 6. Vein 2 arises from the centre of the cell.
