1909] GRINNELL— CALLICISTA INES 93 
tains on the southeast, separated from the latter by the long, deep Palm canon which 
extends from Santa Rosa Mountain to the desert. "These mountains lie in Riverside 
county bordering the Conchilla desert on the west; the Colorado desert proper 
being below and the San Gorgonio pass above the Conchilla desert. The highest 
point of the range is ‘Toro peak (8705 ft.), connected with Santa Rosa Mt. (8000 ft.) 
by a ridge; from this elevated portion these mountains slope more or less abruptly 
to the desert, only about ten miles distant, and 100 feet below sea-level. In this com- 
paratively short distance the life conditions change from the Canadian zone marked 
by the Limber-pine (Pinus murrayana) through several intermediate conditions to 
the Lower Sonoran zone with its peculiar and highly adapted flora and fauna. 
The party, consisting of three persons, was camped at Das Palmos Spring (3500 
ft. alt.), about two miles from Black Mountain. ‘This locality was strictly Lower 
Sonoran with such characteristic desert plants as: Ocotillo (Fouquieria spinosa), 
Creosote-bush (Covillea mexicana), Agave deserti, Yucca baccata, desert willow 
(Chilopsis salina), two or three species of Mesquite, Pinus monophylla, Eriogonum 
fasciculatum, several species of cacti, a scrubby and peculiar looking form of Quercus 
dumosa, and the Western Juniper (Juniperus occidentalis). 'Vhis is the habitat and | 
surroundings of Callicista ines in the Santa Rosa mountains. It was hot in the 
mornings of this our first visit, but towards noon a very strong and disagreeable wind 
blew, which interfered with work, continuing during the afternoon and well into the 
night. On our second visit in the middle of June the conditions were more quiet, 
the weather hot, and things, generally, dryer. C. ines was not rare, but it was not 
conspicuous; its swift flight to some outer, topmost branch takes careful watching 
on the part of the collector. On May 30, I took seventeen specimens. On the 31st 
I visited every Juniper of the day before, beat all around them and kept a careful 
look-out; but did not see one. June Ist went over the same route and took three 
specimens. On June 13, while on another trip, in the upper part of Palm canon 
(3000 ft.) I saw a few more specimens around the Junipers, with practically the same 
surroundings. On June 14 we moved camp, with the pack burros, down to the 
celebrated palm grove (Washingtonia filifera), and on the way saw a number more 
of the butterflies around the Junipers, four or five miles from the grove. On June 18 
we were back again at our Dos Palmos spring camp, and on the following day saw a 
few more ines near Black Mountain; this was my last experience with this butterfly. 
The recorded seasonal range of C. ines is from the last of May to October in 
California. It would be difficult to say how many broods there are until more col- 
lecting and observing is done. But it seems as though it were on the wing continu- 
ally between the two extremes of capture; the broods overlapping, as it seems to me, 
in the same way as with Phryganidia californica.
