bars. The larva is a miner in the leaf of sissu (Dalbergia sissu) and is 
at times extremely destructive to young plants. The moth is curiously

numbers collecting in bushes, plants, wherever there is cover ; at dusk 
they come out and fly about. When the sissu puts out young leaves 
in February, they lay their eggs, a single small egg on each leaflet. 
Tineids are not often a marked feature of the insect life of the plains, 
but this species cannot fail to be noticed in January and February, 
where this tree grows abundantly. Crypsithyris longicornis, Stn., 
is the moth whose larva lives in the little oval case found commonly 
on plastered walls in Indian houses ; the case is of fragments and 
apparently spiders’ webbing woven up with silk and the larva moves
