oblique lines from near the base of the costal margin not 

 united to one another, consequent upon the abbreviation of the 

 inferior or basal one ; the upper line, on the contrary, continued 

 (by means of a terminal elbow) through the red streaks, and 

 uniting with the oblique line immediately beyond the cell ; 

 the fourth or subapical discal line longer, slightly waved or 

 bisinuated instead of regularly concave ; the submarginal 

 line longer and much more slender j only two instead of three 

 large black spots on the fringe at external angle. Body 

 bright ochreous, the thorax scarcely perceptibly paler than 

 the abdomen ; anus lake-red. Expanse of wings 1 inch 

 7 lines. 



Two specimens. Sliillong (Assam). 



I have examined a fair series of the Japanese species, and 

 therefore am in a position to state positively that it is not a 

 variable insect.
