Locality.—Grahamstown (Carl's Eust) (J. Hewitt, 1 <£).

The patch of androconia is much larger than in the other species. In consequence of the suppression of Cu2 and 1A in the fore-wing, M and Cu2 are pushed farther towards the hind margin, and the area between Es and M becomes very Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
