216 LIFE-HISTORIES OF LYONETIADAS 
of transparent flat yellowish silken cocoon-like covering on the surface of 
leaf or stem and rested in a coiled posture inside this cell (Plate LXVITI, fig. 5) 
for about two days, after which they underwent a moult and emerged again. 
This resting stage larva (Plate LXVIII, fig. ¢) is about 4:25 mm. long and 
about 0°5 mm. broad, cylindrical, with distinct segments, uniform yellow, 
smooth, with five pairs of equally developed prolegs. After moulting on 
completion of the resting-stage, however, the appearance and colour are quite 
changed, nor does it mine the leaf any longer but feeds openly on the leaf, 
nibbling the tissue. At this stage the larva (Plate LXVIII, fig. d) has a 
pale yellow head which is smaller than the prothorax and partly retractile 
into it ; the general colour is light vellowish-brown, the dorso-lateral regions 
dark-grey ; on all segments the tubercles are rounded protuberances each 
surmounted by a short yellowish hair ; legs and five pairs of equally-developed 
prolegs pale yellow. In this stage the larva grows to its full length of about 
6 mm., and when full-fed it forms anywhere on the leaf or stem an elongated 
brown longitudinally-ribbed cocoon (Plate LX VIII, figs. e, f) which is fixed 
to the resting surface throughout its length. Pupation takes place inside 
this cocoon, the pupa (Plate LX VIII, fig.g) being about 3-5 mm. long by 
0°75 mm. broad across the thoracic region, yellowish-grey ; the head end 
with a short pointed process ; the spiracles slightly protuberant ; the anal 
extremity blunt, with a short outwardly-directed pointed lateral process on 
each side. The pupa wriggles out through one end of the cocoon before emer- 
gence of the moth (Plate LXVIII, fig. h), which takes place about twelve 
days after spinning up. From these larve, moths emerged between 28th 
October and lith December. (Pusa Insectary Cage-slip 1952.) 
OPOGONA XANTHOCRITA, MEYR. 
Opogona xanthocrita, Meyr., B. J., XXI, 111 (Oct. 1911)(1), Exel-Wnec- AV360 | Ye 
Described from the Nilgiris (3,500 feet) and North Coorg('). It has been 
reared in April 1918 by Mr. K. Kunhi Kannan from imported sugarcane in 
Mysore State. It has also been bred from dead wood by Mr. Beeson. 
TISCHERIA HESTIAS,EMEYR. 
Tischeria hestias, Meyr., Exot. Micr., I, 354 (1915)('). 
Described from Karwar‘(!). 
Bred [in North Kanara] in August 1913 from a larva mining squarish 
blotch occupying space between two veins of a leaf of “ Kewan ” (Helicteres 
isora), no excrement being visible in the mine. Pupation takes place within 
the blotch, the pupa being protruded on emergence of the moth, (Mazvwell.)
