 specinjens can be olitained by reariuK tlie larvie and changing them from time 

 to time from flannel of one colour to that of another. The shape of the 

 successive additions to the case being of different colours, can easily be seen. 

 The pupa state is passed within the ca.se. The adult is a small brown moth 

 with a few dark spots on its fore-wings. 



The Tube-building Clothes-Moth {Tinea ttii)f:t.:cU(i). — The larva of this 

 sjiecies makes a gallery composed of silk mixed with fragments of cloth. 

 This gallery is long and winding and can easily be distinguished from the case 

 of the preceding species. The pupa state is passed within the gallery. The 

 moth differs greatly in ajipearance from the other two species, the fore-wings 

 being black from the base to the middle and white beyond. 



The Naked Clothes-lloth I Tinea hixclliella). — Although this species spins 

 some silk wherever it goes, it makes neither a case nor a gallery. It may be 

 termed, therefore, the Xaked Clothes-Moth, in contradistinction to the 

 other two species. But when the larva is full-grown it malces a cocoon, which 

 is composed of fragments of its food-material fastened together with silk. 

 The adult is of a delicate straw-colour, without dark spots on its wings. 



Protection from Clothes-Moths. 



In late spring or earl.v summer all winter clothing, flannels, furs, and 

 other articles that are to be put away for the summer should be thoroughly 

 brushed and examined for these pests and exposed to the sunlight as long as 

 practicable. Then they should be wrapped carefully iu stour paper, or better, 

 packed in pasteboard 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. — Inseets, Comstock. 



Cattle Horn-Fly (Ihn matohia sriiata, Desv.) Fig. 1C>. 



This troublesome pest of horned stock, which appeared first In Canada 

 in 1.S92, has done much harm by irritating cattle with its bites, so that when 

 it is abundant they fall off rapidly both iu tiesh and in yield of milk. From 

 the time it first appeared in Canada this fly has spread over all parts of the 

 Dominion, reaching the Pacific (;oast iu 1003. but is by far more troublesome
