Mas. Corpus robustum. Proboscis mediocris. Palpi robusti, 

 squaraosi, oblique ascendentes, vertieem non superantes ; articulus 

 3us minimus. Antennae subpectinatae, apices versus glabrae. Ab- 

 domen alas posticas non superans ; fasciculus apicalis, parvus sub- 

 compressus. Pedes robusti, glabri ; calcaria longiuscula, sat gracilia. 

 Alae latae ; anticae acutae, costa apicem versus arcuata, margine

 ascending, not rising higher than the vertex; third joint extremely 

 small. Antennae slightly pectinated to two-thirds of the length 

 from the base. Abdomen rather shorter than the interior border of 

 the hind wings ; apical tuft small, slightly compressed. Legs

 wings acute ; costa rounded towards the tip ; exterior border very 

 slightly convex, rather oblique ; interior border slightly excavated 

 beyond the middle. Hind wings truncated at the tips. 



This genus indicates the close affinity between the Ennomidce 

 and the Geometridce.
