Head with the front narrow, square. Labrum long, triangular. Man- 

 dibles long and slender. Palpi small and slender, narrow, ascending slightly ; 

 third joint minute, pointed, depressed, slightly surpassing the iront. Antennae 

 well pectinated, simple in the female. Thora.x moderately stout. Wings 

 broad, fore wings with the costa convex; apex slightly bordered, slightly sub- 

 falcate. Outer margin distinctly angulated in the middle, being very slightly 

 excavated between the bend and the apex. Hind wings broad ; internal 

 angle subrectangular, even with the tip of the abdomen. Apex much rounded. 

 Middle angle obtuse, a slight .scallop between this and the apex. Venation: 

 no subcostal cell ; the first four subcostal venules are long; the independent 

 vein is situated rather near the sixth subcostal; the posterior discal vein is 

 very oblique, but not curved as in Ellopia. Legs long, slender; hind tibise 

 hardly thickened, very long. S[>urs slender; hind tarsi but little more than 

 half as long as the tibiae. Abdomen long, very slender. Anal tuft rather 

 long. Coloration : pearly-white, with a greenish tinge ; an inner and outer 

 straight oblique line margined without with white. 



This genus, besides being easily identifiable by the pearly-white color 

 of the species, differs a good deal from Theiina, to which it is nearly allied 

 in the venation; while the antennai are scarcely j)lumose, though the shape 

 of the wings is nearly the same in the two genera. 



Larva. — "Caterpillars elongated, convex above, much flattened below, 

 with lateral filamentous appendages as in Calocala; having three pairs of 

 abdominal feet, of which the first are slenderer and shorter than the second; 

 head flattened in front; living on trees. Chrysalides at the surdice of the 

 earth." — Guende. 



Newman stales that the caterpillar of M. iiuirgurildhi "is of a dull olive-
