 small brown worm y 2 inch long, the egg having 

 been deposited there the previous spring, and 

 which will at some time during the early part of 

 the next summer emerge a perfect winged insect, 

 being a grayish moth having about ^ inch spread 

 of wings. They are not as injurious as some, as 

 they do not under ordinary circumstances become 

 very plenty ; but they are hard to reach with the 

 poison, but can be picked and destroyed in winter, 

 wts these, as well as all other insects in the pupa 

 or larva stage, are apt to be infested with parasitic 

 friends, it is well to put the cocoons in a box over 

 which there is fastened window wire screen, which 

 will allow the latter to escape, while it holds the

Sap Suckers. These are a class of very small 

 insects, known as plant lice, of the Aphides. They 

 suck the sap of plants by means of a tubular pro- 

 boscis which they insert into the tender shoots. 

 They are more destructive to house plants than 

 others, but some of the tribe are often destructive 

 when they get a lodgement in the roots of apple 

 and other trees, and from which they are very hard 

 to dislodge, but will generally in a few years be 

 overcome by their natural enemies, for small as 

 they are, they, too, are infested with parasites and 

 also greedily devoured by the larva of the lady bug 

 and lace- winged fly. When their natural enemies 

 are insufficient to hold them in check, they are 

 easily overcome where they can be reached by ker-
