Excerpt from Journal of Entomology and Zoology, Vol. 7: 1915
The genus Via was erected by Haliday (Entomological Magazine. Vol. 1, p. 153, 1833) for the species mollissima, nov"., which is now recognized as being the same as the Limnobia macroptera of Macquart (Recueil Soc. Sc. Agricult., Lille, p. 158, 1826).
The genus includes six described species, macropiera Macquart, the genotype, sororaila Zcttcrstcdt, and bolitophila Loew, of Europe; elegans Osten Sackcn and pauper a Osten Sacken of the United States; and javanica Alexander of Java. The scries of North American material that I have had for study render it probable that paupera Osten Sackcn (Mon. Dipt. N. Am., vol. 4, pp. 277, 278, 1869) is the same species as elegans Osten Sacken (I. c., pp. 276, 277). The insect varies greatly in its body coloration and in the intensity of the pattern on the wings. It seems possible, moreover, that the three European species are merely variations of a single species, but this question cannot be decided at this time.
Osten Sacken in 1859 (Proc. Acad. Nat. Sci. Phila., p. 199) placed this genus in the tribe Pedicini (as Pediciaformia) and in 1869 (Mon. Dipt. N. Am., vol. 4, p. 274 to 278) still retained it in this tribe (as Amalopina). It has been left in this tribe by all subsequent workers, but the study of the immature stages shows that the reference is quite erroneous. The genus Ula should be placed in the Limnopllini close to Ulomorpha Osten Sacken.
