undergo their transformations within the boll or square, to the great 

 detriment of the latter. When the perfect weevil leaves the chrysalis 

 case it either gnaws its way out or escapes when the carpels open ; it 

 subsequently feeds on the external portion of the boll. The difficulty of 

 controlling this insect is great, " for the weevil lives, in all stages except 

 the imago, within the fruit of the plant . . . that it is remarkably free 

 from parasites or disease, that it frequently occupies but fourteen days for 

 development from egg to adult, and the progeny of a single pair in a 

 season may reach 134,000,000 individuals." This bulletin is illustrated 

 with sixteen very good plates and numerous figures in the text. The life- 

 history, parasites, and means of destroying this insect are given in detail ; 

 also figures are given of various beetles which have been mistaken for 

 this weevil. — G. S. S.

 esting account is given of this insect, which preys upon the Mexican

 may prove of great service in the cotton-fields of Texas and elsewhere.
