PLUME-MOTHS OF CEYLON. 
25 
The full-grown larva (suspended for pupation) is about 13 mm. 
long by about 1*2 mm. broad, being cylindrical, slender, shining, 
and appearing quite smooth and naked. There are two principal 
colour varieties :—(i.) Wholly pale green without any noticeable 
markings except a narrow darker medio-dorsal stripe, and this is 
perhaps due to the vessels beneath showing through the skin rather 
than to any dermal pigmented area. Towards the anal extremity 
a pinkish suffusion is seen along the segmental interstices, (ii.) 
Very pale, semi-transparent, pinkish flesh-colour ; interstices of 
segments very pale, semi-transparent green, as are also some 
patches along the sub-median area of most of the segments, 
but the pale green and pink so merge into one another that no 
definite areas can be described. Head very pale green. A pale 
red medio-dorsal line. But some larvae have no green markings, 
being wholly pink. The prolegs are very small and stumpy; 
hooks dark reddish. The hooks on the fourth pair of prolegs are 
attached into the silken pupation-pad. The arrangement of the 
tubercles is shown in the figure. (Plate E., figure 9.) 
Pupation .—The larva pupates very rapidly ; twelve hours is 
sufficient for it to emerge from the fruit, select a suitable place for 
pupation, suspend itself, and complete its metamorphosis. 
Pupa .—The newly-formed pupa is of a bright light green colour, 
the capital extremity tinged with yellowish-brown about the base 
of the antenna-sheath; but it soon becomes of an almost uniform 
reddish gray-brown. 
Imago .—The moth, which usually seems to emerge early in the 
morning, appears after six days. 
Oxyptilus regulus, Meyr. 
B. J., XVII., 135. 
Distribution. —Maskeliya. Only recorded from Ceylon. 
Early Stages .—The life-history is unknown. 
Observation .—This is apparently a very rare species. I have seen 
no specimens. 
Oxyptilus regalis, n. s. 
6 Exp. 14-16 mm. Head and thorax fuscous with a few inter¬ 
mixed whitish scales, vertex with a loose tuft of erected elongate 
scales which do not form a regular cone. Palpi whitish, mixed with 
blackish, second joint reaching middle of face, terminal joint 
slightly shorter than second. Antennae anteriorly whitish striated
