APAMIIDiE. 

 Prodenia retina, Guenee. 

 Mbow, September 4tb, 1881. 



Larva found on a purple-flowered climbing convolvulus 

 (railway creeper). It bas a curiously abrupt truncation 

 of caudal extremity. General colour a pinky brown ; 

 pinkisb line down centre of back. A clouble row of 

 spots exists on eacb lateral margin ; tbe superior row 

 consists of triangular patcbes, black above, witb a j'ellow 

 line at base, except tbe tbird patcb from tbe bead, wbicb 

 is altogctber black in colour. Tbe two anterior patcbes 

 bave more yellow at base tban any of tbe otbers. Tbe 

 inferior row of patcbes is wbolly of a black velvet 

 colour. Legs G, 8, 2. Progression regular. 



Tbe larva buried itself under eartb Sept. 4tb, closing 

 the bole by wbicb it entered witb a plug of damp clay. 

 Tbe cocoon is formed of a cell of eartb some inches 

 below surface. 



Pupa a bright chestnut-colour, with two small spines 

 at apex. 



Imago came out on September 20th.

The larv£e were obtained in great abundance, and in 

 various stages of growth, on the leaves of Eameli, a 

 plant cultivated for the sake of its oil in this locality 

 (see PL XIV., fig. 11). The movements are almost semi- 

 looping in character, yet the larva bas sixteen legs. 



I have not recorded the characteristics of cocoon and 

 pupa, but I believe the change took place in small 

 earthen cells below surface of the ground, and that the 

 pupte were of the usual chestnut-colour, without any 

 white efliorescence on surface.

 of pistils, which it devours, going from flower to flower,
