MICtiOLEPIDOPTEKA.

(Terminalia catappa). It pupates in very compact felted cocoons on the 
trunks of trees in which state it is often found abundantly. We figure 
the larva of Belippa laleana, Mo. (Plate XXVIII, fig. 14), a gelatine 
grub, in which the outlines of the segments are lost, and the dorsutn 
consists of a smooth semi-transparent mass of tough tissue; the beautiful 
tufted red-brown moth is found in the plains rarely. 
Neocastniid^:. 
No proboscis ; hindwing with vein 8 free, remote from 7, frenulum pre¬ 
sent , l.c. absent, forewing with vein 5 nearer 4 than 6. 
A single moth, found in Tenasserim, is the sole Indian representa¬ 
tive of the family. Neocastnia nicevillei, Hampson, is described in 
Trans. Ent. Soc., Lond., 1895, p. 285, as also in Fauna of India, Moths, 
Vol. IV, p. 471. 
MICROLEPXDOPTERA. 
The characters of the group are defined above on page 432, and we 
have there stated our reasons for adopting this grouping. Apart from 
the purely structural characters of the group as shown by the venation 
of the wings of the imago, there are other characters which make the 
group at least a useful one in practice if not also a logically correct one 
phylogenetically. The eggs of these moths are, as far as known, different 
in character from those of the Rhopalocera, and from the majority of the 
Heterocera ; they are flattened, often scale-like or elongated, with the 
micropile at one end ; they are not ornamented with radial ridges and 
polar points but are often reticulate or simply smooth. The larva has 
the five pairs of prolegs equally developed as a rule, the hooks on 
them being in a circle and not set in two opposed lines; they are 
smooth cylindrical larvse with few short hairs and of the form known 
generally as “ Pyrali-form.” They live commonly in concealment 
(except Pterophoridce) and do not feed openly ; where they are leaf eat¬ 
ers, they roll the leaf or hide themselves with it or in it in some manner; 
many are borers in soft tissues, and if we exclude the large borers in woody 
tissues, the majority of the agriculturally important boring caterpillars 
are included here.
