From Hodges, R.W. 1965 you can see these features in the image above:

• "labial palpus white, second segment with broad black band (scales white basally, black distally) on outer and ventral surface from one-fifth to one-half and a narrow preapical black band, third segment with a black band at one-fifth, three-fifths, and apex."

• "antenna with scape off white and a few dark gray tipped scales on dorsal surface, shaft orange with black on basal half of many segments dorsally..."
