study by Mr. IN’. Filipjev, with kind permission to retain one. 
This very interesting insect (the third of the genus) marks clearly 
the phylogenetic relationship between Hyponomeuta and Ethmia.

Head (denuded); tongue absent. Antennae hardly J serrulate, 
shortly ciliated, scape short, without pecten. Labial palpi moderate, 
loosely scaled, terminal joint as long as second, obtuse (directed

middle. Hindwings nearly 1, trapezoidal-ovate, cilia \ ; 2 from
