LooMis Bureau of Plant Industry, United States Department of Agrimlture A PAPER in which the 12 known species of the milliped order Colobognatha in the United States were alhided to in descriptions, keys, or diagnoses appeared in 1928.^ Since then three additional species of the order have been discovered, and although one of them was found in an unrecorded locality in Lower California, all its close relatives are members of our fauna, and there is possibility of its range extending into the United States in the southern California mountains adjacent to the Mexican Boundary. This species and another new one from Tennessee belong in the genus Brachycyhe, and they double the number of species it contains. The third species is from near Brownsville, Tex., and extends the tropical genus Siplionophora within our borders. Descriptions of these new species and several new locality records of previously known forms are herein presented. The type specimens of the new species are in the United States National Museum. 1 Cook, O. F., and Loomis, H.
