Isostula vlcina, ii. sp. 



I^early allied to /. diui.sa, but differing in its smaller size ; the 

 hyaline cuneiferm patch, upon median area of primaries, ex- 

 tending nearly to the base and divided throughout its length by 

 the median nervure ; the postmedian hyaline band, tapering to a 

 point at its upper end ; the .subapical fasciole reduced to a 

 narrow bifid litura ; central hyaline streak of secondaries much 

 narrower ; expanse of wings 1 inch, 8 lines.

Only ditt'ers from Hiinleucerta, in neuration, in the fact that 

 the radial, instead of forming a fourth median branch, is con- 

 tinuous with the recurrent nervure. Type M. pyrrhorlum. 



The body of Mdadatia is much less robust than in Hij( deuce rhi.
