being entirely confined to the fen districts of Cambridgeshire, 
Huntingdon and Norfolk. 
So "widely distributed an insect as P. Machaon may naturally 
be expected to present many local forms. The largest specimens 
are those from Japan ; India and China seem to furnish lighter- 
coloured specimens than the European districts, the dark markings 
being less strongly expressed in these. A smaller and darker form 
called Splujnis by Hilbner is taken in Sicily and North Africa. 
Laeva bright green, with deep black rings which are spotted 
wfith red; V-shaped process reddish. Feeds on fennel (AnstJmm 
fenicuhim) and wild carrot (Daucus Ckirota), and other Umhelliferce. 
Appears from June to September. PI. V., 3.

Expands 2’50 to 3 in. The wings shorter and propor- 
tionately broader than in Machaon, which species the fore wings 
resemble in their markings, except that the band of the hind 
margin gets gradually broader as it approaches the inner margin ; 
the nervures and spots are very strongly marked and the base very 
dark. Hind wings with the marginal band very broad and reaching 
to the discoidal mark (which is not nearly so conspicuous as in 
1\ Machaon), its internal edge not clearly defined. The blue- scales 
concentrated so as to form six or seven bright blue spots. The 
tails are very short. Body, head, and anteimse of the same colour 
as those of P. Machaon. PI. II., 1. 
Times or Appearance. — May and June. 
Habitat. — Corsica and Sardinia, frequenting mountainous 
districts. 
Larva. — I take my description and figure of the larva from 
the original paper by M. Gene, the first describer of the insect, 
entitled “Be quibusdam insectis Sardiniie novis ant minus 
cognitis.” He describes it as bright green, furnished with yellow 
tentacles, and covered with short prickles, each segment having 
short interrupted black and longitudinal lines and four red spots. 
It feeds on Ferula connnunis in June and the beginning of July. 
Perhaps an extract from his paper in the author’s own words may
