PAPILIONID.'E. 
h. Medesicaste, Illig. Mag. ii. 181 ; Hilb. i. 632. Has the 
wings of a much paler colour than the typical form ; in some it is 
nearly white. This is rather smaller, and is the French form, 
being found at Cannes, Hyeres, and other places in the South of 
France in May. Mr. Timins, who is acquainted with the larva of 
Medesicaste, describes it as specilically distinct from Pamina. But 
it seems to me that the difference is chiefly one of coloration.

This beautiful variety has the red spots enlarged and expanded so 
as to cover the greater part of the wings ; the ground colour is 
pale straw-yellow, and the spots light rose-colour. This variety 
is very rare and local, being only found in Digne, in South-Eastern 
France. It is very scarce in collections. PI. III., 5. 
Genus 3. — DORITIS, Boisd. 
Thais, Lat. 
Clubs of antennsB curved. Palpi shorter than in Thais. Body 
hairy. Wings rounded, with black costal spots, semitransparent. 
Hind wings rounded, with an even unindentated margin. Abdomen 
of female not furnished with a horny pouch. 
This genus is intermediate between Thais and Parnassius, 
but seems to be nearer the latter, and perhaps nearer still to the 
Australian genus Eunjciis.

Expands 2 to 2-25 in. Fore wings semitransparent, of grey 
tint, with small transverse black striic ; two large black spots in 
the discoidal cell reaching to the costa close to the hind margin, 
and parallel to it is a row of elongated black spots. Hind wings

bordered throughout its whole length with neutral grey, and inside 
this a row of about six eye-like spots orange-blue and black from

and shining, apparently scaleless, excepting as regards the black
