LUEIIDORFIA,— PARNASSirS. 491 
possess specimens of the species. I at first considered it to be merely a local 
form of L. puziloi, but the following characters are amply sufficient to separate 
it from that species. In the first place the " pouch " of female oi L. japonica 
is without a keel, and is black instead of light chestnut ; this, without 
reference to other points of difference, at once distinguishes it ; but, further, 
it is much larger in size, the ground-colour is darker, and the anal blotch is 
broader and of a bright crimson. 
Found in Japan in mountain districts. Mr. Pryer (Ent. Mo. Mag. xxiv. 
p. 66) says : — " This insect appears very early in the year ; my first specimens 
were obtained on the 15th of April, but it was then getting over ; the males 
appear before the females, and it frequents wooded paths on the mountains, 
and is very easy to capture." 
I have received a form of this species from Central China, where specimens 
were taken by a native collector in the mountains in the neighbourhood of 
Chang-yang. These differ from Japanese specimens in being smaller ; the 
secondaries agree better with the Amurland L. puziloi *, but the red colour 
which forms a subanal patch on the secondaries of hoih. imziloi and japonica 
is continued in this Chinese form as a subraarginal band as far as the discoidal 
nervule; the body is more slender and less hairy than mjaponica ; the hairs 
are reddish brown instead of whitish, and the pouch of the female only differs 
in its smaller size. This form may be known as var. chinensis (Plate XXXIII. 
fig.l).

* L. puziloi, ErschofF, occurs commonly in Southern Amurland. Eefcrring to this species, 
Graeser (Berl. ent. Zeit. I8S8, p. 03) states that the larva is black, covered with a few stiff black 
hairs, and having the segmental divisions bluish white. Feeds on Asarum until July. He adds 
that he found it commonly under stones in the vicinity of the food-plant.
