408 Mr. H. J. Elwes’ catalogue of the 
357. Delias descombest. 
Pieris Descombesi, Boisd., Sp. Gen., p..465 (1836). 
Common at low elevations, and up to 38000 ft., from 
March to December. I found it with P. hippoides and 
other Pieride fond of settling on the sweet-scented 
flowers of Cinchona Ledgeriana in the lower plantations 
at Mongpo. I have a very curious hermaphrodite of 
this species, in which the right-hand wings are those of 
a female and the left-hand ones those of a male; the 
corresponding sides of the extremity of the abdomen 
also appear to be those of the two sexes, but in their 
dried and somewhat shrivelled condition I cannot see 
whether the male clasper on the left side is perfect. 
858. Delias hierte, var. indica. 
Thyca hierte, var. indica, Wall., Trans. Ent. Soe.

the last.

Having recently written on this species, I was careful 
to take especial notice of its habits during my last visit 
to India, and, though I am not able to change my 
opinion that there is only one species under the several 
names which have been given to it, yet I am able to add 
something to our previous knowledge. I found the dark 
form ithiela most common in Sikkim from May to
