SATYRIM; 93 



OVUM, Round, and green. 



LARVA. On Grasses, especially Cynosurus cristatus, 

 from April to September. 



On May 7 th 1891, 1 obtained a caterpillar of this 

 species from the ovum. 



The larva changed to a pupa on July 18 th , fastened 

 to a blade of grass in the interior of the breeding- 

 cage. 



An imago (of the var. Lyllus) emerged on August 2 nd . 

 The stages, from the birth of the caterpillar to the exit 

 of the perfect insect from the chrysalis, had thus 

 occupied exactly twelve weeks and four days. 



It moulted its skin four times. The following will 

 give an idea of the intervals occupied in this process.

3 rd do July 6 th . 



4 th when it finally discarded its skin,

PUPA. " Sometimes uniform green, sometimes 

 with three black lines on the wing cases, anal point 

 reddish ; round, and without angular projections." 

 Lg. But. Eur., vol. I, p. 310. 



Mine had the numerous black markings (I counted 

 fifteen), among them a faint dorsal line. In length, it 

 was 4 1/2'", and in girth it measured 2'".

Larger and brighter than the type, and the apical 

 spot is very distinct.
