Type (male) from Mt. Mlanje, Nyasaland, 7. xii. 1912, 
and other males (S. A. Neave). 
Type (female) from Uchweni Forest, near Witu, 25-27.

One female from Chiromo, Nyasaland, Ruo River (R. C. 
Wood) (1916). 
Three males and two females from 150-200 miles west of 
Kambove, 3500-4500 feet (S. A. Neave), 1907, 230. 
A species nearly allied to P. negligens, Adams, but some- 
what smaller, and the genitalia in male are quite different, 
being longer and more slender and with no white tuft above. 
In the female the much longer ovipositor will distinguish 
it at once. :
