turn to their ordinary colour within an hour. After the third moult 
(Fig. 29) the wings are easily distinguishable, and after the fourth 
(Fig. 30, Pl. 8, Fig. 5) moult the tegmina are long and narrow and still 
have on them the sensory organs which were formerly on the un- 
expanded mesonotum (Fig. 36). When emerging from the old skin at 
the first ecdysis, the snout is red, dotted with white and is curved 
upwards at about the same angle as the adult, and the whole insect is 
of a pale orange-red, but the tegmina in a few minutes become green 
spotted with yellow. This tegminal colouring however, disappears as 
the organs expand, and they also become pale orange, spotted with 
deeper orange. In an hour from the beginning of the moult, and after 
the wings have attained their full size, the green colour appears at the 
base of the tegmina, extends downwards and within two hours reaches 
the tips, and the wings, though pale, are of their natural colours. At 
the commencement of the moult, as soon as it has burst the ceuticle of 
the thorax, the insect crawls out and begins to bend downwards 
till it hangs to the old skin by the hind tarsi. After a little time 
it bends upwards and catches hold of the old skin with the mid- 
and then the fore-legs, walks forwards till it reaches the bark, from 
which it hangs by the fore tarsi, and, by shaking, rids itself of the 
old skin, which clings to the tip of the abdomen. The wings are 
small and cerumpled inwards like those of Lepidoptera at first. They 
attain their full size in an hour. In two hours and a quarter from 
the beginning of the moult the insect is in adult colouring, except 
that the wings are rather pale instead of brilliant orange, and the 
broad border not yet deep black, whilst the snout is not so red as 
at first — more yellow or red brown. The bright red colour of the 
snout is not attained till two or three weeks after the moult. 
Again the increase in bulk after the moult is very surprising. The 
insect begins to feed a day or two after the final moult. !) 
The wax of the Pyrops is formed in bundles or masses of thread

1) The only figures or descriptions of nymphs of the larger Fulgoridae 
of which I know, are by BURMEISTER (1845, Gen. Ins., Fulgora subg. 
Pyrops), who figures a nymph of Pyrops sp.? (fig. 6), and myself, who 
have figured the nymph of an unknown Fulgorine in: Bull. Hawayian 
Plant. Entomol., Vol. 3, tab. 7, fig. 7—8; and have described and figured 
others in Bull. cit., Vol. 1, p. 389—390, tab. 29, fie. 11. G. W.K.

in some neotropical genera, viz. Phenax etc., in which the tail may be
