Pachetra leucophcea ab. — Mr. G. H. Heath, a specimen from 
"Wye, 1912, with the ground colour much whiter, and markings black, 
the usual form having brown markings. 
Thera juniperata, variation in colour of pup;e. — Mr. G. H. Heath, 
imagines from Morayshire and Wye, Kent, bred 1912, the Scotch form 
being much the smaller. The exhibitor stated that the Scotch pupte 
were black, whilst the southern form were green. 
Vanessa io. — Mr. H. B. Williams, a long series from various 
localities showing some very interesting minor variation. Chiefly two 
series for comparison, bred from Chalfont Road larvae in 1911 and 
1912. The year 1911 was a very hot season, and the larvie in this 
brood were reared in a warm room, the temperature being from five to 
ten degrees above the outside temperature. The year 1912 was a cool 
season, and the larvae in this brood were reared in a cool shed out of 
doors, the temperature being about ten degrees below the outside 
temperature. By this means, the natural conditions of both seasons 
were slightly accentuated. An extreme specimen of each brood has 
been selected, and these two specimens, placed together in the series 
exhibited, form a very striking contrast. The chief characteristics of 
the imagines of the two broods may be compared as follows:— 
1911. 
1912. 
Primaries :—- 
Ground colour. 
Eye-spots 
Outer margins. 
Dark. In one or two 
specimens there are traces 
of a central shade. 
Bluish suffusion much 
reduced. In one or two 
specimens this is extreme, 
and the ground colour 
shows clearly beyond the 
chain of white spots. 
Unspotted. 
Dark. Perhaps not quite 
to such an extreme as the 
1911 specimens. 
Bluish suffusion in¬ 
creased. In one specimen 
this is extreme, and the 
ground colour is entirely 
absent beyond the chain of 
white spots. The bluish 
suffusion encroaches on 
the ground colour in the 
central area of the eye. 
Many specimens show 
traces of dark wedge- 
shaped spot3 in the outer 
margin, opposite the small 
white spots. 
Secondaries :— 
Ground colour. 
Size of reddish blotch 
variable, tending to abso- 
lescence in one or two 
Size of reddish blotch 
variable. 
Eye-spots 
specimens. 
Generally small. One or 
two specimens have exceed¬ 
ingly small eye-spots. The 
blue scaling very strong, 
and spreading over almost 
the whole of the eye-spot. 
Generally large, brilliant, 
and conspicuous. The blue 
scaling not strong. In 
some specimens there are 
only a few blue scales ar¬ 
ranged in three rows. 
Size :— 
Small, owing to the 
great rate at which the 
larval fed up. 
Large, as a rule. The 
larval in this brood fed up 
very much more slowly.
