which were more than he wanted to sow in April, and with them 
two moths, which were the Tinea sarcitella. He squeezed a maggot 
out of one of the many cases or galleries which were made at the 
bottom of the drawer and attached to the wood. The peas had 
been put there for seed in September, 1844. I was not a little 
surprised at the end of last September, on taking out of a tin 
canister some bundles of barley which had been infested by the 
ChlorojJS* to find a dozen caterpillars of Tinea sarcitella and the 
moth (figs. 41 and 42, magnified). The roots were covered with 
dry earth, and the stalks and leaves were mouldy, but there was 
nothing for the larvae to feed upon excepting the corn, unless they 
found the pupae of the Chlorops anywhere. The earth amongst 
the roots was connected by their webs, and many of the cater- 
pillars were full grown. 
Tinea sarcitella has long been recorded as a most mischievous 
little moth in our dwelling-houses, where it is common the greater 
portion of the spring, summer, and autumn. I have frequently 
observed it on the trunks of fruit-trees in gardens as late as Sep- 
tember, and in the house in October and November. Sparrows' 
nests are also a great harbour for them, as the caterpillars revel 
amongst the feathers, wool, and rubbish which form the lining, 
and in this way they are always on the premises, and are con- 
stantly entering our sleeping-rooms and other apartments, when- 
ever the windows are left open after sunset. 
The female deposits her eggs upon clothes, blankets, curtains, 
carpets, or any woollen articles on which the larvae feed, living in 
cylindrical cases which they form of the materials on which they 
subsist, covered with their excrement, and in which they change to 
pupae. The caterpillar is a lively wriggling animal, about half an 
inch long when full fed (fig. 37) ; it is soft and white with a 
yellowish tint, and sparingly clothed with finelongish hairs, some- 
times having a slate-coloured stripe down the back, arising from 
the food ; the head is horny, of a chesnut brown, and furnished 
with little strong jaws and minute horns ; the first thoracic seg- 
ment is likewise horny and similar in colour, but paler ; it has 
also 6 pectoral, 8 abdominal, and 2 anal feet : fig. 38, magnified. 
The pupa is sometimes enclosed in a distinct tough cocoon 
(fig. 39), similar in texture to the cases ; the pupa is brown and 
shining (fig. 40), the sheaths enclosing the wings being very 
long, and the horns and eyes are visible through the horny 
envelope. 
The perfect insect belongs to the Order Lepidoptera, the 
Family Tineid^, and the Genus Tinea of Linnaeus, which, 
from its great extent, has been divided by modern naturalists into
