This specimen appears to be referable to this species, though differing 



considerably in coloration from the descriptions. The S-shaped mark 



on the tegmina is but little crved, while the posterior part of the 



tegmina is as black as the general color of the insect. The wings also 



carry a longitudinal dull ochraceous line along the greater portion of 



the discoidal region, in continuation of the median line on the 



tegmina.
