10DIS VERNARIA. 55 
nings most kindly supplied me with a number of 
the larvee of I. vernaria; and when quite full-grown 
I described one as follows: 
Rests in nearly a straight position, firmly attached 
by its anal and ventral claspers to a twig or leaf-stalk 
of its food-plant, from which it projects with the 
rigidity of a stick at an angle of about 45 degrees ; 
the head is prone, deeply divided on the crown, and 
the two divisions are produced into acute points, 
directed forwards like ears; the face is flat, and 
the mouth bent under and brought into contact with 
the legs, which are massed together, forming a lump 
beneath the head; the body is dilated on the sides by 
the presence of a rigid skinfold, almost resembling a 
lateral keel; the second segment is produced dorsally 
into two acute points, similar to those of the head, but 
rather longer, and, like these, directed forwards ; the 
ninth, tenth, and eleventh segments are incrassated ; 
the anal flap is triangular and pointed; it is equal in 
length to the anal claspers; the body is transversely 
wrinkled, and every part of the head and body is 
finely shagreened. The colour of the head and legs 
is purple-brown; the body is green, exactly of the 
same tint as the twigs of the clematis on which it 
feeds; and the frosted appearance of the surface (each 
point of the shagreen being tipped with white) makes 
the resemblance to a growing and succulent twig stili 
more exact; the spiracles are ochreous. 
On the 26th of June the first larva changed to a 
pupa, and on the 8th of July to an imago; the thorax 
of the pupa is smooth but, not glabrous, being coarsely 
punctured ; it 1s suspended by the tail, which is fur- 
nished with minute hooks adapted for the purpose, as 
in the Suspens: among the butterflies ; the colour is 
green, excepting the eyes and antennew, which are 
tinged with purple. (Hdward Newman, Ent., August, 
1872, VI, 168.)
