two on the inner side of the orbicular mark, and three exterior, of 

 which the first is interrupted by the reniforui mark ; marginal space 

 blackish, including a cinereous undulating submarginal line ; mar- 

 ginal lunules black. Hind wings cinereous, very slightly hyaline, 

 brown-bordered ; discal point and veins brown ; marginal line 

 blackish, festooned. Length of the body 10 lines ; of the wings 

 20 lines. 



Most allied to M. insulsa, from which it may be distinguished 

 by the difference in the orbicular and reniform marks and in the 

 exterior line of the fore wings.

 Antennae very minutely setulose. Abdomen cinereous, extending 

 somewhat beyond the hind wings. Fore wings with three double 

 zigzag black lines; first line very near the base; second on the 

 inner side of the orbicular mark, which is large and black-bordered, 

 and has a blackish space between it and the reniform ; the latter is
