" If struck at wdth the net two or three times and missed, this 

 insect becomes terrified and drops to the ground, where it perches 

 and is easily taken ; this specimen ( $ ) behaved in this way."

Nobody, comparing a series of this species with T. regidaris, 

 could hesitate about keeping them separate ; the fact is that few 

 Lepidopterists have the least idea as to what T. regularis really is ; 

 they mistake it for the extreme wet form of the present species, 

 which it neither resembles in outline of wing, border, or pattern 

 of under surface ; moreover it has a female with a broad black 

 border to the secondaries. I consider the nearest ally to T. regularis 

 to be possibly T. marshalli, but it is really much more like T. solo- 

 monis of the T. Candida group ; it has a heavier costal border to 

 the primaries and is, as a rule, a smaller insect ; the under surface 

 also though without spots is also destitute of dark borders. In the 

 Museum we have twenty-one wet-season examples of T. regularis, 

 including four females ; excepting that they are comparatively 

 broader and shorter in wing, they more nearly resemble T. zoe 

 than T. marshalli.

" The first of its kind, I think, I have seen in these parts, and 

 somewhat a surprise." (B. O.) 



I believe it will be found that this species ranges over nearly 

 the whole of Africa.

This species is new to the Museum. The single example taken 

 is a little shattered ; the dark border of the primaries and the 

 spots on the under surface of the secondaries are barely indicated ; 

 it probably represents the intermediate phase of the species. 



76. Teracolus chromiferus.

This is evidently the dry phase of the species ; it is decidedly 

 smaller than usual, the male finely black-veined above, the magenta
