lighter larva described above (Powell). 



[Page 156.] Cocoon. — Formed on the surface of the ground, and 

 composed of dried leaves and earth (Powell). 



[Page 156.] Pupa. — Measured 49mm. from head to point ot 

 spike (below average size) ; slim, graceful, of polished appear- 

 ance, light yellowish-brown in colour. Head and thorax finely 

 roughened by small wrinkled pits. Proboscis-case lightly wrinkled 

 transversely. Body minutely pitted. The wing-cases are situated 

 transversely with thin light brown irregular lines, reminding one 

 of the surface-marking of the pupa of Melanargia syllius, but, 

 in this case, the markings are not so pronounced. The first 

 free abdominal segment has a wrinkled brown patch on each 

 side extending as far as the spiracle and partly covered by the 

 previous segment. Spiracles of medium size, oval and brown. 

 Cremastral spike dark brown, straight and pointed. [The pupa 

 described entered this stage at the end of June, 1902, the larva 

 having been found on June 14th at Hyeres.] (Powell). 



[Page 158.] Habits of imago. — Occurs regularly twice a 

 year at Hyeres, in April and May and again in July and 

 August. The May examples are not uncommon and are to be 

 seen frequently flying round the flowers of red valerian, on which 

 it loves to feed, and may sometimes be seen in considerable num- 

 bers, e.g., in a gorge above La Farlede on May ist, 1902, but 

 they are very active and difficult to capture. They appear to feed 

 quite as readily in full sunlight as at dusk, in the spring, yet I 

 have no notes nor recollection of having seen summer specimens 

 in the daytime, although they occur frequently at honeysuckle and 

 other flowers in the evening, and I have known the species to come 

 to the electric light (Powell).
