Nyasalaud Protectorate ( British Central Africa) : Samulu 

 stream, near Chibwano's, Chikala, 29. iii. 1906 {Dr. J. E. S. 

 Old) : taken at same time and place as the specimens of 

 Pangonia compacta centralis referred to above. 



Although presenting a strong superficial resemblance to 

 Pangonia compacta, P. fodiens can be distinguished at once 

 by its narrower head and body, less prominent face, and the 

 fact that the tarsi are tipped with brown ; the front above 

 the antennse is also narrower ; the remaining difierenccs are 

 sufficiently indicated in the above description. For syste- 

 matic position, see remarks above, with reference to Pangonia 

 compacta.
