NOTE ON THE GENERIC TITLE TRIFURCULA
Published online by Cambridge University Press: 31 May 2012
Extract
In my “Descent of the Pierids,” Jan., 1900, I have used Trifurcula, Stand., Iris., VII., 56, for a genus of Andean Pierids, but this name is preoccupied in the Lepidoptera by Zeller, 1848, Staud. & Rebel, Cat. II., p. 221.
Staudinger states (l. c.) thate he had at first named the genus Piercolias, so this name though open to criticism, should be used for the Pierid genus with the type of huanaco, Staud. The morphological value of the neurational character of the primaries of Piercolias, which led Staudinger to choose the name Trifurcula, does not seem to have been apperciated by him. The gradual progress of R2 towards the apices, and of M1 towards the Radius, brings these branchlets in juxtaposition.
