of Ontario. In the Entomologist for August, 1884 (vol. XVI., page 141), may be found 

 a full account of it by Prof. Saunders, who suggests that it might with great propriety be 

 designated the maple tree bark-louse instead of, as it is commonly called, the grape vine 

 bark-louse. It was first described in 1884 by Dr. Rathvon, of Lancaster, Pa., who 

 observed it for several years on basswood, and who gave it the name innumerabilis on 

 account of its immense numbers. The lice appear in the form of brown scales ; those of 

 the females having waxy filaments projecting from them. The eggs are laid among these- 

 filaments, and are very numerous — from 500 to 2,000 — the female commencing to lay in 

 the latter part of May, and continuing for several weeks until she dies. The young lice 

 when hatched are yellowish white, and can move freely about. They soon spread all over 

 the branches, and seek the twigs and places where the bark is tender. Selecting suitable 

 spots, they insert their beaks and commence to devour the sap, gradually assuming the 

 scale- like form and becoming incapable of further change of habit or position. When fully 

 grown the male emerges from his scale and appears as a delicate, minute two-winged fly,, 

 but th^ females always retains her degraded form. 



68. Lygus monarchus, Uhler. This bug has only recently been described (Can. 

 Ent, Vol. XVIII., page 208) by Mr. Uhler, who states that it is a very common insect 

 in some localities, and has been taken by him on maples, alders, and many other trees and 

 shrubs. He has found it near Quebec, and it seems to have a wide distribution in the 

 United States. 



69. Capsus goniphorus (Say.) is a brilliant red or scarlet bug, found not unfre- 

 cpiently on various trees, including maples. Mr. Fletcher informs me that it is nocturnal 

 in its habits. 



70. Ceresa bub alus (Fab.) is one of the tree-hoppers, its popular name being the Buffalo 

 tree-hopper. It is found upon a great many species of trees, and like all these insects 

 lives upon sap drawn from the tree by means of its proboscis. 



Dr. Pachard mentions also the following : 



71. Psylla annulata, Fitch. On sugar maples. 



72. Aphis aceris, Linn. On acer pensylanica. 



73. Lecanium acericola, Walsh and Riley. 



74. Lecanium acericorticis, Fitch. On silver maple. 



INSECTS TPvOUBLESOME IN THE HOUSEHOLD AND HOW TO DEAL 



WITH THEM. 



BY THE REV. THOMAS W. FYLES, SOUTH QUEBEC. 



Certain insects are so troublesome within doors that they may well be denominated 

 " Household Pests." Many of the species are easily recognized by the most careless 

 observers ; and yet their life-histories are to many persons altogether unknown, as are 

 also the right methods to abate the annoyances they occasion. 



It shall be my effort to give, in this paper, a brief account of the most troublesome 

 of these insect offenders and to point out some of the remedies that may be used against 

 them. 



1 shall tell of some insects affecting (1) Personal Comfort, (2) Food, and (3) House 

 Plants. 



I. — Insects Affecting Personal Comfort. 



1. The House Fly (Musca domestica) belongs to the family Muscidce, in the order 

 JH/ptera: The beautifully reticulated eggs of the insect are laid by the parent fly in horse- 

 manure. They hatch in twenty-four hours, and a week suffices to bring the maggots to 

 their full growth. In turning over the manure pile, in the summer months, the farmer will 

 find them in abundance, as he will also the pup*, which, in form and size, resemble grain,
