38 The varieties of Papilo dardanus cenea 
No. 19. This is a shade lighter in colour than usual, and has the 
white discal patch of the fore-wings suffused with dull orange-ochreous. 
No. 20. A very interesting dry-season example of trophonius. The 
colour is a deep brick-red. The discal patch and disco-cellular streak 
are very largely developed and nearly coalesce. They are obscured 
over the greater part of their surfaces by a brick-dust suffusion. The 
black hind-marginal border of the hind-wings is reduced to a narrow 
band enclosing the spots of the submarginal series, which are relatively 
larger and more ovate than is usual. It was taken on the Berea, 
Durban, on 10th August, 1907. 
I have not thought it necessary to describe the under-sides of the 
specimens submitted because such variation as occurs is chiefly a 
modified reproduction of the upper-side pattern.
