 eggs close down to the skin on the hair, and where 

 there are many these are strung close to each 

 other, consequently often overlooked, even when 

 somewhat carefully sought for. The eggs of these 

 two insects are very much alike, and attached to 

 the hair in the same method, so that a single de- 

 scription will answer for both. A proper knowl- 

 edge of them is so essential to understanding the 

 methods of destroying them, that we shall give a 

 somewhat minute description in explanation of the 

 figures here given. The eggs, as seen, are pear- 

 shaped. The posterior end is pointed, the ante- 

 rior truncate, and furnished with a flattened round
