 others, were taken on the hill-side at Trayas. They 

 were all rather worn. 



LARVA. On Aristolochia pistoloehia, in March

OBSERVATION. Medesicaste is now considered as 

 specifically distinct from Rumina, of which it was 

 formerly supposed to be a variety. 



The Rev. Douglas C. Timins, who is acquainted 

 with the larva of Medesicaste, describes it as 

 specifically distinct from Rumina, on account of the 

 caterpillar, which differs from that of the type. 



The difference, however, seems to be chiefly one of 

 coloration.
