Recorded from Madeira, the Canary Islands, Tunis, Egypt, Somaliland 
and Aden. Common throughout India. We have it from Pusa, Coimbatore 
and Bhutan. 
This species has been reared at Pusa from larve found attacking the 
fur of a deer’s hide. The larvee live next to the skin, hidden amongst the 
hairs, which they eat. The attacked hairs do not fall off at once, as their 
cut bases are hound up in a greyish silken webbing which the larve exude 
and in which they live, their frass sticking to this webbing. At the slightest 
pull the hairs come off in large tufts along with the silken webbing, leaving 
the skin quite bare, 
The full-grown larva is about 10 mm. long and about 1:25 mm. broad, 
eylindrical, yellowish dirty white, skin soft and transparent ; head yellow 
brown ; segments with thin white scattered hairs ; five pairs of equally deve- 
loped prolegs. 
Pupation takes place inside the silken webbing in a white silken cocoon. 
The pupa is about 6 to 7mm. long, yellow brown ; anterior portion of dorsum 
of abdominal segments with a transverse row of small spines which increase 
in size on the successive segments towards anal extremity ; anal segment 
dorsally with hook-like spines with their tips bent anteriorly. The pupa 
wriggles out of the cocoon for about half its length before emergence of the 
moth ; in some cases the empty pupa case is entirely pulled out by the emerging 
moth. 
In spite of their concealed mode of life, the larvae are lable to be parasi- 
tized by a Tachinid fly. (Pusa Insectary Cage-slip 824.) 
CRYPSITHYRIS HYPNOTA, MEYR. 
Crypsithyris hypnota, Meyr, B. J., XVI, 753-754 (1907)("). 
Described from Peradeniya, where the larva occurs in a case on lichens 
under rock-ledges('). 
CRYPSITHYRIS LONGICORNIS, STT. (PLATE LVII, FIG. 2.) 
Tinea longicornis, Stainton, T. E. 8. (n. s.), V, 113 (1859)(?). 
Crypsithyris longicornis, Lefroy, Ind. Ins. Life, p. 539 (1909)(?). 
Originally described from Calcutta('). Also occurs at Pusa. 
The “larva lives in the little oval case found commonly on plastered 
walls in Indian houses ; the case is of fragments and apparently spiders’ webb- 
ing woven up with silk and the larva moves slowly along the wall. Its nourish- 
ment is apparently the size in the whitewash or some similar organic material,
