184 LIFE-HISTORIES OF TINEID 
It has been bred at Pusa from larve collected on 5th to 25th June 1916 
in silken tubes amongst dabhi grass. On 30th June 1916 no more larve 
could be found although pupz and empty pupa-cases were then found in the 
tubes. The larve are found in silken tubes which extend almost vertically 
downwards for several inches into the soil. At the mouth of the tube bits 
of dry grass and other rubbish are knitted together and these lie on the ground 
and completely hide the presence of the tube. The larva is very like that of 
Melasina but is apparently distinguishable by its smooth head—transversely 
corrugated in Melasina. The full-grown larva is about 18 to 20 mm. long, 
cylindrical, pale yellow ; head smooth, red-brown ; prothoracic shield large, 
lighter brown than head and divided by a narrow yellow medial line ; hairs 
on segments long, not arising from tubercles ; five pairs of equally developed, 
short prolegs. 
Pupation takes place within the larval tube, no special cocoon being formed. 
The pupa is about 12 to 14 mm. long and about 2°5 to 3 broad, cylindrical, 
slightiy bent ventrally ; on the dorsal region of the anal segment there is a 
pair of pointed processes arising from a common transversely-flattened base 
and with their tips directed anteriorly. By wriggling movements and with 
the help of these processes, the pupa can move freely up and down the silken 
tube. Before emergence of the moth the pupa wriggles up to the mouth 
of the tube and partly issues out of it before the mothescapes. (Pusa Insectary 
Cage-slip 1404.)

Amydria tineoides, Wism., P. Z. 8., 1907, 1018-1019 (1908)(°). 
Originally described from Mhow(!). ‘Not uncommon in India (4) 
and probably widely distributed. 
Larva figured by Lefroy(*) and van Deventer(?) ; the latter is probably 
more accurate and shows the larva as 5 to 6mm. long, whitish, head shining 
brown with lighter intersutural lines, plate of two large, narrowly divided 
medially, brownish, plates of 3 and 4 smaller, broadly divided, brownish ; it 
livesin a case about 6 to 8 mm. long by some 2 mm. broad, broadest and slightly 
flattened in the middle, slightly expanded at either end. 
Food :—Dried tobacco leaves (#). 
Note. Jt is possible that Lefroy’s figure, ascribed to this species, really represents the 
larva of Selomorphu insectella.]
