One specimen was captured at Niangara, November 20, 1910. This 

 is the continental form of the insect which is found in Madagascar and 

 was named N. saclava by Boisduval. It is very abundant on the east- 

 ern coast and I have long series from Natal and Mombasa.

Of this species the collection contains eighty-seven specimens, in- 

 cluding some of the varieties to which discriminating students have 

 given names founded in some cases upon the measurement of the size 

 of the spots and bands. The form lativittata Strand, the author of which 

 informs us that the mesial band of the secondaries is eight millimeters 

 wide, is represented. I discover that all of the specimens falling into 

 this category are large and well-developed females, as is also the case 

 with a lot of specimens I have from other parts of Africa. I call into 

 question the specific validity of this so-called "species," which is not 

 even a variety. 



I note, however, that there is a distinction, which I do not believe 

 has been previously pointed out, between the specimens which come 

 from the hot woodlands and those from the more open country of the 

 eastern and southern grass-lands. As it happens, most of the speci- 

 mens representing this species were taken at Niangara and Faradje.
