strong anastomosis of C of hindwing with SC, and in the 
general build. The face is slightly prominent, flattened, 
smooth-scaled, the antenna in the ^ subdentate, with thin 
fascicles of moderate cilia, in the ^ shortly ciliated; SC^'^ 
are coincident, not stalked, and anastomose or are connected 
with to form a rather long narrow areole; the costal 
area of hindwing is ample, and C, after anastomosis, diverges 
from cell even more sharply than in Narragodes, to which 
the genus is apparently related.

(Plate XLVIII, fig. 36.) 
d' 22-28 Him. Face prominent, rounded, smooth-scaled ; build 
more slender than in M. ')ioctnatn, Warr. ; wings elongate, of delicate 
texture, hindwing with anal angle rounded. Head and antenna 
pale greyish fuscous; thorax and forewing pale greyi.sh fuscous 
above, paler beneath ; abdomen and hindwing dirty white, sparsely 
irrorated with fuscous, especially the di.stal half of hindwing above. 
Forewing with a dark discal spot and ill-defined, zigzag antemedian 
and postmedian lines; antemedian from about one-third costa, 
strongly angled in cell, scarcely traceable below middle of wing ; 
postmedian from fourth-fifths costa, throwing out a sharp, deep tooth 
into median area between SC“ and R*, a broader projection into 
median area between R* and R^, and another in submedian area, 
but with a tendency to produce distad-directed teeth on all the 
veins ; a dark mark on inner margin before one-fourth, probably 
indicating a remnant of a subbasal line ; marginal area somewhat 
paler than the rest of wing, especially just distally to the postmedian 
line ; a row of dark marginal dots between the veins. Hindwing 
with terinen subcrenulate, marginal dots as in forewing; otherwise 
almost without markings, the cell-spot small and faint. Under¬ 
surface almost without markings ; each wing with a very small, 
faint cell-spot; marginal spots weaker than above, more inclined to
