detached. From twelve to twenty-five are laid at a time on the 

 upper-side of a leaf. 



Habits of larva. The larvae are gregarious and are sluggish. Under 

 domestication they are very easy to rear. 



Araivacus linus, Sulz. (PI. XVIII, figs. 5 — ah.) 



Ovum. Laid singly on stem of plant near the top. 



Larm. Head small, retractile. Abdomen green covered with 

 fine downy hair and with a series of large tufts down the back. 



Habits. The larva is very sluggish and usually eats holes from 

 the upper-side of a leaf of cocoa. The butterfly nearly always 

 breeds in a shady place near a stream, and can never be induced 

 to fly far, seeming to be much attached to its favourite haunt. 



Mithras hcmon, Cram. 



Larva. Pink or whitish-pink and very much the same colour as 

 the very young shoots of the cocoa on which it feeds. The shoots 

 that spring around the stem or trunk of the cocoa are those usually 

 selected.
