ETERUSIA TRICOLOR.

The specimen we have here the pleasure of figur- 
ing is unique. It was recently brought from the 
Assam territories, and is one of the numerous rarities 
in the Rev. F. W. Hope’s collection. 
ETERUSIA TRICOLOR. 
PLATE III. Fig. 1. 
Hope, Limuean Trane., vol. xviii. pi. 31, fig. 4. 
This and the two following insects we place toge- 
ther, because they present several points in common, 
although there remains, notwithstanding, consider- 
able diversity among them. For accurate descrip- 
tions of the two first, we are indebted to Mr. Hope, 
in the work above cited, who refers them, with 
doubt, to the family Zygenid®. Nothing, indeed, 
can be more uncertain, in the present state of our 
knowledge, than their true relations ; and these we 
are not likely to be in a condition to determine, till 
we become acquainted with the metamorphoses and 
general history of the group. As far as we are 
acquainted with their geographical distribution, they 
seem confined to Eastern India, most of them being 
from Assam. Eterusia * is characterised as a genus 
* En^unas, qui alterias seu diversi essentise.
