case. The adult is a small brown moth with a few dark 
spots on its fore wings. 
The Tube-building Clothes-moth, Tinea tapetzella (T. 
tap-et-zel'la).—The larva of this species makes a gallery 
composed of silk mixed with fragments of cloth. This gal¬ 
lery is long and winding and can be easily distinguished 
from the case of the preceding species. The pupa state is 
passed within the gallery. The moth differs greatly in ap¬ 
pearance from the other two species, the fore wings being 
black from the base to the middle and white beyond. 
The Naked Clothes-moth, Tinea biselliella (T. bi-sel- 
li-eria).—Although this species spins some silk wherever it 
goes, it makes neither a case nor a gallery. It may be 
termed, therefore, the Naked Clothes-moth, in contradistinc¬ 
tion to the other two species. But when the larva is full 
grown it makes a cocoon, which is composed of fragments 
of its food-material fastened together with silk. The adult 
is of a delicate straw-color, without dark spots on its wings. 
Protection from C/oiJies-mot/is. —In late spring or early 
summer all winter clothing, flannels, furs, and other articles 
that are to be put away for the summer should be thor¬ 
oughly brushed or examined for these pests, and exposed to 
the sunlight as long as practicable. Then they should be 
wrapped carefully in stout paper, or better packed in paste¬ 
board boxes, which can be procured at small cost, and the 
crack between the cover and the box closed by pasting a 
strip of paper over it. 
The Angoumois Grain-moth, Gelechia cerealella (Ge- 
le'chi-a ce-re-a-lel'la).—Although this insect is closely allied 
to the Pine-leaf Miner, its habits are very different. This 
insect feeds upon seeds, and especially upon stored grain. 
It occurs throughout our country; but it is especially de¬ 
structive in the Southern States. In that part of the coun¬ 
try it is extremely difficult to keep grain long on account 
of this pest-and certain beetles that also feed on stored 
grain. The adult moth is of a very light grayish-brown
