orange or vermilion with dark-brown or black legs and antennae, 
while the amount of black on other portions of the body increases 
with each successive molt. a 
First stage. — The nymph when first hatched from the egg is pale 
coral red in color, with long, dark brown or nearly black legs, the 
proximal half of the antennae being of the same color and the remainder 
pale coral, becoming darker soon after hatching. The antennae and 
legs are of nearly equal length, about one-fourth longer than the body 
(with the head). The rostrum, which is kept closely folded under the 
body when the insect is not feeding, is of the same color as the legs 
and about three-fourths as long as the body. The posterior portion 
of the body is sparsely tuberculate, the arrangement being as shown 
in the accompanying illustration (fig. 4) at a. The legs and antennae 
are clothed with sparse short black hairs. The tibiae of the hind legs

show no evidence of the expansions which appear in later stages. The 
length of the body when first hatched is about 2.3 mm , and the width is 
about 0.8 mm . 
Second stage. — With the casting of the first skin, the nymph takes 
on a more elongated appearance generally, the head, body, antennae, 
and legs all being longer and more cylindrical, while the tubercles 
become more pronounced. The two dorsal abdominal tubercles and 
the anal extremity become black, and a pair of minute tubercles 
usually show just behind the pair back of the hind legs. The hind 
tibiae shows slight evidence of enlargement. Length when fully 
matured, 6 mm . This stage is illustrated at £, fig. 4. 
Third stage. — Superficially this stage (fig. 4, c) looks but little different 
from the second. The thorax is longer than the head, the black por- 
a The differences between the nymphs of this species and of L. phyllopus are not 
nearly so marked as in the two cucurbit-feeding Anasas, tristis and armigera.
