NOTE REGARDING HABITATS AND RHOPALOCERA OF DONNER PASS, CALIFORNIA
In our previous paper (Emmel & Emmel, 1962) on the Donner Pass butterfly fauna, we unfortunately omitted a description of the fourth plant association in the Dry-Meadow habitat. This association, called here the Lake Mary road area, is listed in Table 1 and shown in Figure 2 of that paper; the following remarks should be added after the "Summit Valley" description (1962: p.28): 2-D. LAKE MARY ROAD
This is the dirt road from Donner Summit (Highway 40) to the Sugar Bowl Lodge; it passes by Lake Mary and parallels the railroad snowsheds. The area (elevation 7000 feet) is generally dry and covered by chaparrallike plant growth. Typical plants are Ceanothiis and buckwheat (Eriogonum), with a few willows (Salix).
A FURTHER NOTE: Because of the identical butterfly faunas of the two sub-habitats listed under "I. Wet Meadow" (1962, p.27), the data concerning the two faunas were combined in one column (Habitat "1") in Table 1 (1962, p. 37-38).
We thank Dr. C. B. Williams for bringing these points to our attention.

SONG SPARROWS FEEDING ON LEPIDOPTERA
For the past few days, June 4th through 7th, 1962, I have noticed the common Song Sparrow, Melospiza melodia, hawking insects here. Upon closer inspection it was ascertained that very often the insects were lepidopterous. Many moths (I am not able to identify moths) were taken. Several Everes comyntas, Strymon, Lycaenopsis argiolus, and Lycsena phlseas americana were also ingested by the sparrows.
