Male. Yellow. Vertex black. Antenne tawny. Thorax 
with a black band in front, and with five black stripes, the middle 
one broad and irregular. Abdomen luteous above, with a whitish 
tinge, and a black band on the hind border of each segment. Legs

the less black at the tips of the fore wings, the greater space between 
the third and fourth inferior veins, and the more acutely angular 
tip of the discal areolet.
