Extract

About a year ago Mr. F. M. Brown called the writer's attention to the aberrant venation of one secondary of a specimen of Erebia magdalena Strecker. The aberration, of the type shown in Figure I, consists in the presence of an extra cross-vein connecting veins Rs and M1 a few millimeters beyond the end of the cell. Later, in studying series of other species of the genus, a similar variation from the normal (Figure 2) turned up in several specimens. The facts are presented in the following table, in which the results of examination of some material from the genus Oeneis is also included.
