186 LIFE-HISTORIES OF TINEIDA 
these side-pieces are dry-earth colour and whitish inside. The larva extrudes 
itself from one of the ends up to about the metathorax, whilst it walks and 
feeds, the remainder of the body being protected by the case. When disturbed 
it withdraws its head inside the case. Pupation takes place within the case, 
the pupa wriggling out to some extent to one end of the case on emergence 
of the moth, which appears in November. There seems to be only one brood 
annually. (Pusa Insectary Cage-slip 380.) 
HYPOPHRICTIS SP. (PLATE LV, FIG. 2.) 
A Tineid larva, apparently belonging to a species of Hy pophrictis, was 
found at Pusa in January 1916 underground in the nest of an ant, Polyrhachis 
sp. It was enclosed in a flat silken case as shown in figure b. Unfortunately 
the larva died and no more have been found, so that the moth has not 
yet been reared. It may possibly belong to H. solliciia, Meyr. (Exot. Mier., 
II, 85) which was also described from Pusa. 
SCARDIA SISTRATA, MEYR. 
Scardia sistrata, Meyr., Exot. Micr., I, 618 (1916)('). 
Described from Puttalam, Wellawaya and Peradeniya in Ceylon and 
from Pusa(!). We have it from Pusa, Chakradharpur and Coimbatore. 
Larva feeding in decayed fungus (Polyporus)('). At Coimbatore this 
species was reared from larvee in fungus and at Pusa from larve in fungus 
(Fomes sp.). 
Larve were found at Pusa on 22nd August 1908, boring into the thick 
tissue of Fomes sp. and producing tunnels filled with pellets of frass. HExtern- 
ally the presence of the larvee in the fungus is indicated by dry pellets of frass 
webbed together into small masses. The larva was described as about 20 
mm. long and 2°5 mm. broad, cylindrical, pale yellow, skin soft and trans- 
parent ; head and prothoracic shield brown, shiny ; five pairs of fully developed 
prolegs. Pupation takes place inside the tunnels in the fungus, the pupe 
being found near the mouths of the tunnels which open externally, the opening 
being closed with silk and excrement. The pupa is about 12 to 13 mm. long, 
cylindrical, brown ; third and following abdominal segments with two. trans- 
verse ridges across dorsum, the ridges surmounted by fine raised points ; 
anal segment with a pair of curved hooks on ventral side. On emergence of 
the moth, the pupa wriggles out of the tunnel to some extent and, when the 
moths have emerged, many empty pupa cases are found projecting out of the 
body of the fungus, (Pusa Insectary Cage-slip 741.)
