Female holotype from Isla Partida, Gulf of California, in California Acad. Sci. Collection, examined. NEW SYNONYMY. Discussion. Although no types of either of Hentz's species exist, the name A. bi- color may be assigned with certainty to this species. Specimens from both North Carolina and northern Alabama are avail- able, and are identical with the nearly continent-wide species to which the name A. bicolor has been applied for over 100 years. Other species of Ariadna are of very limited distribution in the United States: A. arthuri in the southern part of peninsular Florida and the Keys, A. pilifera in southern Arizona, and A. fidicina in the southern half of California west of the mountains. In spite of Hentz's denial of this fact, his Pylarus pumilus, described in half a dozen lines, can be nothing but the juve- nile of A. bicolor, as suggested by Emerton (1875). Koch's description of A. pallida contains nothing distinctive of any par- ticular species of the genus. A large series of specimens from Pennsylvania, the type locality of A. pallida, differs in no signifi- cant way from other populations assigned to A. bicolor. Ariadne rubella Keyserling, from New Orleans, differs only by its reddish color, according to the description. Some Louisi- ana specimens are distinctly more reddish than most A. bicolor, but are otherwise indistinguishable. In the absence of freshly collected specimens from Louisiana, it is not even certain that the reddish color is natural. Banks's A. mexicana was supposedly dis- tinguishable from A. bicolor by its more. Please note that these images are extracted from scanned page images that may have been digitally
