This singularly-formed insect was captured in Assam by Mr. Griffith, and 
appears to be undescribed as far as I have had an opportunity of obtaining 
intelligence: respecting its habits little is known, and it seems doubtful with 
what family it is to be associated ; for the present it is arranged with the Zy- 
gænidæ. It is probable that it ought to be arranged with the Lithosiade.

This insect appears to be a nondescript, and is one of the most beautiful in 
* Eterusia, from the Greek érepouasos, qui alterius seu diverse essentiæ.
