This species perhaps represents a new genus ; but as it is 

 possible that the structure of the appendages of the meta- 

 thorax may differ in the sexes, I refer it provisionally to my 

 genus TetrameUa (only known in the male sex, type Schizas- 

 pidia plagiata, Walk.), with which it agrees in all other 

 essential characters.
