188 LIFE-HISTORIES OF TINEIDH 
Originally described from Ceylon('), this species is widely distributed 
in India, where it has been recorded from Campbellpur(?), and has also been 
found in Formosa(*). We have it from Peradeniya, Chapra and Pusa. 
At Pusa it has been reared from farmyard manure (cowdung) collected 
on 25th June 1916. The larva was boring the lumps of cowdung and living 
inside a silken tube around which pieces of cowdung and pellets of frass were 
fastened. Pupation took place in elongate-oval silken cocoons with stout 
walls and the pupa wriggled out to some extent through one end of the cocoon 
just before emergence of the moths, which took place from 13th to 23rd July.

A cosmopolitan species described, under at least eight other names, from 
North and South America, Hawaii, West -Indies, West and South Africa, 
Seychelles, India, Ceylon, Celebes, Makassar, and Queensland. |For more 
complete synonymy and distribution, see('°).| We have it from Pusa, 
Rangpur, Coimbatore, Darjiling, Mercara, Pollibetta and Nagpur. 
Larva on dead animal and vegetable matter—on muscular fibre attached 
to skull of a hippopotamus(!®), destructive to bales of country -blankets in 
Caleutta(* *), destructive to insect collections(”), on various dried vege- 
table substances(’). 
This species has been bred at Pusa on several occasions from larvee found 
feeding on dry tobacco leaves, also from larve on stored coriander seeds, on 
Setaria italica grain in store, on wheat flour, and on Dolichos biflorus (seeds *), 
and at Nagpur it has been reared on bean (in store 2). 
The egg is about 0°25 mm. long by 0°17 mm. broad, pearly white, changing 
to very light-brown before hatching. The eggs are laid singly. Before 
depositing an egg the female extrudes her ovipositor for about 2mm. and moves 
it from side to side, then raises it upwards between the wings and then with 
a jerk deposits an egg at the utmost reach of the ovipositor, and then moves 
to another place to lay another egg. The eggs hatch in about eight days, the 
young larva being about 1:25 mm. long, with a light-brown head.
