Book Description
This annotated bibliography of the Coccoidea, or scale insects, has been prepared as a reference base to be used in further treatment, primarily in catalog form, of the information that has been published on the classification of the group. No general bibliography covering coccid literature has been published since 1868, and the last comprehensive catalog appeared more than fifty years ago.

Book Description
This revisionary study of the genus Asterolecanium has evolved from unsuccessful attempts to identify accurately an injurious member of the genus which evidently was introduced into the United States and from difficulty experienced in satisfying numerous requests for correct identifications of other economically important species. Consideration of literature and specimens in these efforts disclosed a degree of confusion regarding many of the especially destructive species which could be clarified only through a critical classificatory review of the kind here presented. In this publication the writer has attempted to provide descriptions and illustrations adequate for the identification of the intended species and a classification of these species based primarily on a critical study of their morphology.

Book Description
The peanut, for over 20 years a leading crop in the Southern States, reaches the consumer in many widely different forms. Once grown exclusively for sale roasted in the shell and for feeding to hogs, peanuts are now more widely known in the salted form, and even larger quantities are marketed each year as peanut butter and peanut candy. In some years a considerable volume of peanuts has been crushed and the crude oil shipped to manufacturers of oleomargarine, compounds and vegetable shortenings, and salad oil. The course taken by the peanut in its journey from farm to the consumer, then, is necessarily a varied one, with many bypaths.
