Snodgrass^ Egbert Evans. The Thorax of the Hymenoptera. Proc. U. S. 

 Nat. Museum, Vol. 39, pages 37-91, witli plates 1-16; published October 25, 1910. 

 In this paper the author gives much extremely useful information on the thorax 

 of hymenopterous insects. In such a study it was necessary, of course, to make 

 many dissections and drawings. The reproductions of these latter are particularly 

 good. In addition to the 77 figures on the plates, 16 other figures appear in the 

 text. 



Wheeler, William Morton. Ants: Their Structure, Development and 

 Behavior. New York: The Columbia University Press, 1910. This remarkable 

 book of 663 pages is one of the most important contributions to the literature of 

 entomology which has appeared during the year. It is a work that has been much 

 wanted and will be of extremle value the world over. The book is divided into 

 thirty chapters, each of which contains a number of parts. Chapter I treats of 

 "Ants as Dominant Insects." This is followed by chapters on external and internal 

 structure, development, polymorphism, history of myrmecology and classification 

 of ants, distribution, fossil ants, etc. At the end are several appendices: A — 

 Methods of Collecting, Mounting and Studying Ants; B — Key to the subfamilies, 

 genera and subgenera of the North American PormicidfB, for the identification of 

 the workers; C — A list of described North American ants; D — ^Methods of exter- 

 minating noxious ants; E — Literature. Beautiful illustrations appear throughout 

 the text. This magnificent work will undoubtedly lead many to make serious 

 studies of these most interesting insects, about which so much reliable information 

 has now been made readily available.

 of the Genus Macromia. Proc. U. S. Nat. Museum, Vol. 37, pages 369-398, with 

 plates 35-36; received 7 Jany., 1910. This paper on the genus Macromia will be 

 of much value to students of dragonflies. The American species are distributed 

 generally over the United States and Southern and Eastern Canada. Nine species 

 are treated of at length, three of which are described as new. Seven figures, show- 

 ing wing venation, are included in the text.
