larva was of a dirty white colour, with a black head and 

 black cervical shield. 



T. lanariella* Head ochreous. Labial palpi dark 

 brownish. Antennae dull fuscous. Thorax and abdomen 

 pale yellow. Fore-wings pale yellowish-brown or pale 

 yellow, with a silky lustre, and immaciilate ; sometimes 

 slightly dusted with fuscous on the costa at the base, and 

 with a brownish spot on the end of the disc. Hind-wings 

 pale shining yellow, cilia the same. Exp. al. 5 '50 to 6*50 

 lines. 



I am not sure this is not a variety of the previous species, 

 and has, perhaps, been heretofore described, as it is a very 

 common inhabitant of houses. The larvae feed on woollen 

 substances, carpets, clothes, &c., of which each constructs a 

 case. I have reared a great many in confinement, and have 

 also found that they feed on the bodies of their dead progeni- 

 tors, when the opportunity offers. 



I find the egg described in my note-book as spheroidal and 

 of large size for so small an insect; I doubt, however, the 

 correctness of the term descriptive of the figure. The young 

 larvae appear after about two weeks, and do not immediately 

 make a case. The mature larva is white, with a dark brown 

 head and a cervical shield of the same hue. They reach 

 maturity about the middle of March, and climb the sides of 

 the walls to the ceiling of the room in which they feed, and 

 suspend or attach their cases. The imagos of the first brood 

 appear about the beginning of May; there is another in 

 August and September. 



T. nubilipennella.^ Labial palpi yellowish, dark brownish 

 exteriorly. Head and front dull fuscous or brownish-yellow. 

 Antennae dull dark brown. Thorax brownish-yellow. Fore- 

 wings deep fuscous, sprinkled with dull yellowish, with a 

 yellowish spot on the inner margin at the base, and the
