Shape of Thaumapus, to which I should have referred it, 
but that the scutellum and metathorax appear to be entirely 
unarmed.

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 Tetramelia (only known in the male sex, type Schizas- 
pidia plagiata, Walk.), with which it agrees in all other 
essential characters.
