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.

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 Zygenidse. 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 

 * Engouo-ios, qui alterius seu diversi essentia'.
