yellow, distally dark wood coloured-brown. Length of forewings: 10 mm. Tambora, Sumbawa. 
L. semibrunnea Heyl. (14 h). The yellowish-white forewing densely dusted with a brownish grey, semibrun- 
with a whitish costal margin, exhibits in the proximal half a large black spot extending almost to the base; 
before the middle at the costal margin a small, short, black stripe; behind the middle in the cell-spaces black 
longitudinal streaks. Hindwings brownish-grey with ochreous-yellow fringes. Java. 
L. chiloides Wkr. (=torta Wkr.. humeralis Wkr., dasypyga Fldr.) (14 i) differs from the preceding chiloides. 
hy the absence of the large black spot; in the middle of the costal margin there is another black stripe and post- 
median traces of a transverse band. Hindwings orange-yellow. The $ has instead of the middle costal-marginal 
spot a black dot at the lower cell-end and dark dusting in the basal half of the proximal margin; hindwing more

L. bipunctata Wkr. (= mysolica Sivinh.) (15 k) is very much like chiloides, bid the costal-marginal bipunctata.
