siusculee, J ciliate, Palpi maxillares plicati, b-articulati. Palpi la- 
biales cylindrici pilosi, articuli secundi apice supra setis una pluri- 
busve instructo. Waustellum subnullum, Ale anteriores oblongo- 
ovatee, raro elongate ; posteriores ovate squamate longe ciliate ; an-

Head above and in front hairy. Ocelli none. Antennie moderately 
thick, not so long as the anterior wings, in the ¢ slightly ciliated. 
Maxillary palpi folded, five-jointed. Labial palpi cylindric, hairy, the 
apew of the second joint furnished above with one or more bristles. Tougue 
hardly perceptible. Anterior wings oblong-ovate, rarely elongate (7. 
nigripunctella) ; posterior wings ovate, clothed with scales, with long cilia. 
From the discoidal cell of the anterior wings five veins run into the 
costa, and five terminate on the margins below the apex. 
The maxillary palpi do not appear to be developed in Cochyh- 
della, biselliella, or nigripunctella; T. biselliella even shows a 
slight difference in the neuration of the wings. The small species 
T. bistrigella, ete., have only fow veins from the discoidal cell to 
the costa, and fowr others terminating on the margins below the 
apex of the anterior wings. 
The perfect insects of this genus appear in summer, those which 
occur in houses are liable to be found throughout the year; they 
fly but for short distances, but run very nimbly and keep their 
antenne in a continuous state of agitation. Some of them are 
gaily coloured, but most of the species generally found in houses 
are of sombre hues. ‘The larvae feed on various kinds of sub- 
stances, cloth, horse-hair, feathers, etc., cork, fungi, decayed wood. 
Many of them, like 7! pelZioned/a, construct portable cases in which 
they reside, exserting only the three first segments for the purpose 
of locomotion; others, like 7. ¢apetzedla, construct covered gal- 
leries of the substance on which they are feeding, thus destroying 
much more than they actually consume; others, like 7. dise/liedla, 
do not construct cases nor have regular galleries, but spin to- 
gether portions of the substance they are eating for the purpose 
of a cocoon, preparatory to assuming the pupa state. Those which 
feed on fungi and decayed wood, form galleries in the solid sub- 
stance, which they line with silk. 
A great deal has been written on these insects with a view of 
preventing their ravages, but hitherto with little success. Where 
they once gain a footing it is very difficult to get rid of them; 
and I have myself been annoyed by 7 disedliel/a establishing 
itself in. the linings of sofa, chairs, etc., and in the carpets. An 
occasional baking of the furniture will help to keep their numbers 
in check. 
These insects became known from their ravages at a very early
