LORQUINIA 
drawn: Malva parviHora L. is very noticeably phototropic. Also, 
physiologically; leaves of plants under ordinary conditions arrange 
themselves so as to receive the maximum amount of light on their 
faces, from which the fact can be deduced that light is necessary for 
plant nutrition and growth.

VARIATION IN LEPIDOPTERA 
In the foothills back of Tallac, Lake Tahoe, in July, 1916, a 
female specimen of Limenitis Lorgnini, remarkable for its size and 
marking, was taken. 
It spreads two and five-eighths inches across the wing tips, and 
the wings are broader and rounder than in the normal form. The 
white spots on the primaries are smaller than usual, and, where the 
edge of the wing would normally be, there is a row of nine faint 
white dots. The wing extends from one-eighth to three-sixteenths 
of an inch beyond these dots, giving the appearance of an extra black 
band. The secondaries are marked similarly in this respect. 
The brown tint on the tips of the primaries extends inward 
along the costa to the first set of white spots, of which there are four, 
with a suggestion of the fifth, and along the side of the wing nearly 
to the angle. 
In the secondaries, or hind wings, the edge of the wing is 
curved in between each vein. There is a fringe of short white hairs 
between each vein. This marking is so pronounced at the fifth vein 
as to suggest the beginning of a tail. The insect as a whole presents 
a very striking appearance. 
There were three or four specimens like the one described above 
noticed where this one was taken, but they were in bad condition. It 
is possible that this may be a local variety, as none of the normal 
form were noticed. 
A peculiar female of Colias eurythem\e was taken in Eagle Rock 
in late 1916. It is slightly smaller than the normal, spreading one 
and one-half inches. The submarginal row of yellow spots is cov- 
ered over with black, with the exception of two dots, faintly discern- 
ible. On the underside of the primaries there are three large and 
two small black dots at the inner edge of the dark outer border. The 
underside of the secondaries is much like the normal form. The en- 
tire specimen is rather deep and dusky, having a black shadow over 
a greater portion of the wings.
