MACROLEPIDOPTERA y^-j 



This genus appears to belong to the Stcnia group, and is quite remote from any 

 other Hawaiian insect ; hence I thought it might be an introduced exotic form, but it 

 seems amply distinct structurally from anything described, and Prof J. B. Smith, to 

 whom I sent a drawing and particulars on the chance of its being an American insect, 

 returned it as unknown to him. At present therefore it remains an isolated fact 

 without explanation.
