 lists of lesser groups, and analytical tables of the N. A. (north of Mex.) 

 genera of Bombylidae, of the U. S. spp. of Exoprosopa, of the Cal. spp. of 

 Cyrtopogon, and of lesser groups. Especial attention is paid to the classi-

 important families, and to the habits of Cecidoinyia, Argyramoeba and

 of the Western Region, and of California in particular, describing the 

 limits and physical and faunal characteristics of the region and its affinities 

 with and analogies to other faunal regions.
