AMIANTASTIS, n. g. 
Head very shortly rough-scaled on crown, face with appressed 
scales ; ocelli posterior; tongue absent. Antennae |-§, ciliated, 
scape short, without pecten. Labial palpi very short, porrect, 
filiform. Maxillary palpi absent. Hind tibiae loosely haired. 
Forewings 2 from angle, 2-5 equidistant, parallel, 6 parallel, 7 to 
costa, 8 from angle, 9 rather remote, 10 absent, 11 from middle, 
accessory cell developed. Hindwings 1 , elongate-ovate, cilia ^ ; 
2 from |, 3 from angle, 4 sometimes absent, 5 somewhat approxi¬ 
mated, 6 and 7 somewhat approximated at base or parallel. 
Apparently related to Lypusa. Type manicola. Notwithstanding 
structural differences, the two species are closely similar and should 
not be separated.
