PART 1.— TAXONOMY. 



INTRODUCTION. 



During recent years the damage by termites has attracted con- 

 siderable attention; one of the authors (Thomas E. Snyder) has been 

 particularly interested in this matter, and in the course of his work 

 has gathered a large amount of material. During the season of 

 1917 Mi\ Snyder made a field trip through the Gulf, Southwestern, 

 Rocky Mountain, and Pacific coast regions principally to collect 

 termites and obtain data on their geographical distribution and habits. 

 It was seen that there were various species in the country undescribed 

 or unrecorded, and Mr. Banks has undertaken to distinguish these 

 forms so that the economic work may proceed on a surer basis. The 

 work on taxonomy and the new species are to be credited to Nathan 

 Banks alone. ^ Mr. Snj^der, who has published on the ecology of our 

 termites from his wide field observations, has here presented the 

 biological side of the subject and worked up the data on geographical 

 distribution and plotted this on the maps. Mr. Banks has had the 

 advantage of studying the Hagen collection containing various types 

 and has seen collections from the American Museum of Natural 

 History and several experiment stations in the West; but the col- 

 lection of the Bureau of Entomology, especially that of the Branch 

 of Forest Entomology, is by far the most complete in native species 

 and is the principal basis of the work. 



Nearly all of the drawings have been made by Miss Mary Carmody 

 under the guidance of Mr. Snyder; the remainder were made by 

 Mr. Banks, It is desired to here express our appreciation for Miss 

 Carmody's conscientious and careful work,
