EXPEKIMENTS UPON .ACE^A ENCEDON.

Three commixta are included in the series of in/uscata, namely, 2 males 

 emerging July 7 and 1 female emerging July 9. Commixta possesses a 

 fulvous fore-wing sabapical bar with a white hind wing, approaching that of 

 the form alcippiiia. One other male of July 7 has the former of these 

 characters only, and is thus transitional. Some It/cia of this series also 

 exhibited a slight suffusion of the fore wing with a fulvous tint. 



Wild Larvce 2. 



The larvse were collected on the bank of Oni River, about two miles 

 north-west of Oni. Their whole life-history fell within the dry season, 

 which lasted from about mid-Nov. 1910 to mid-March 1911. The dates of 

 emergence are shown in the following table.

One female commixta, emerging Dec. 10, is included in the series of 

 infuscata. The hind wing is whiter than in most other examples — so much 

 so, indeed, that the specimen might, except for the fulvous fore-wing bar, 

 be fairly classed under the form alcippina. 



Companies : — The following 7 companies of larvse were bred each from 

 a batch of eggs laid on a single leaf of the food-plant Commelina, by the 

 Oni River, about two miles north-west of Oni Camp. Great care was taken
