This curious, primitive gall is evidently formed as follows: The larvae get into the apical region of the developing stem whera they are able to interfere with the normal growth of two very young but definitely formed leaves ; the embryonic leaves associated with the apical growing point are suppressed and may be observed in the gall as a compact mass of tissue filling the space between the petioles of the leaves involved in the gall proper. One or two empty pupa cases of the web type were found in the galls.

A NEW ABERRANT FORM OF VANES~A VIRGINIENSIS DRURY (HUNTERA FABR.) .
. BY CHAS. L. Fox.
The museum of the California Academy of Sciences contains an apparently undescribed variety of Vanessa virginiensis, which Mr. E. P. Van Duzee, the curator, has turned over to the writer for description.

of posterior half blackish ; base shaded with olive-brown; apical area marked nearly as in the typical form except that the sub- marginal line is broader and more suffused; posterior half showing an absence of the black bars found in typical virginien* except for a slight trace in the cubitus2 cell near a submarginal white spot usually found in the typical form.
Secondaries :. Ground color as
in primaries ; submarginal row of blue eyelike spots represented by a row of small indistinct white blotches which run into a suffu- sion of white toward the anterior margin; exteriorly without the submarginal black line found in typical virginiensis; fringes as in typical form. .
Under side. Primaries: ground color whitish with the olive- brown markings of virginiensis much reduced; disk pale apricot- orange, pink in typical form, showing a white spot exteriorly and wanting the black bars of the typical form; base with a double black mark; costa with two black bars. as in virginiensis. Second- aries : ground color nearly white; a basal band and two bars on the cell approximate anteriorly, one medial, the other apical, blackish, veined with white.; anal area delicately shaded with blackish scales; submarginal eyelike spots characteristic of virginiensis much re- duced, the anterior almost obliterated; subapical black line heaviero than in typical forms; other markings found in virqiniensis absent. Described from one male taken by Mr. J. A. Kusche in Golden Gate Park, San Francisco, California, November 11, 19 11. Type in collection of the California Academy of Sciences. Named for .
the Ahwashtee tribe of Indians formerly inhabiting the peninsula of San Francisco.
This variation of
V. virginiensis corresponds with the form mnelleri of Vanessa carp in the markings of the upper surface, while beneath, by its white color, it approaches Vanessa cardui elymi Ramb.1 In the type specimen there is a slight folding of the primaries making the outer margin appear to be too deeply notched below the apex.
1 This form "is quite distinct from var. fulva Dodge and from the aberration mentioned by Mr. H. M.
