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-el'la). — 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 Clothes-moths. — 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 cercalella (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
