Smith — Leptothorax 
115 
Figueroa Mt., Santa Barbara County; 11- 4 -45 ; C. H. 
Muller; from an oak gall. 
From these data it can be seen that the new ant is com- 
monly found on the canyon live oak, Quercus chrysolepis 
Liebm., which is distributed along the California Coast 
Range and the western slopes of the Sierra Nevada. 
This oak however, is not confined to California, but occurs 
in southwestern Oregon, northern Mexico and Baja Cali- 
fornia, southwestern Utah and New Mexico, southeastern 
Nevada, and much of Arizona. At Los Gatos the species 
has been collected from twig galls made on the canyon 
live oak by cynipid wasps belonging to the following 
species: Heteroecus pacificus (Ashm.), H. sanetce-clarce 
(Fullaway) and Disholcaspis truckeensis (Ashm.). 
Tritoma dissimulator Crotch. — There seems to be 
no record of this species from either Maine or Mass, 
and it is listed as from “111.,” which is the locality given 
by the describer. I took it at Paris, Me., June 15, 1910, 
and July 12, 1914, and in June, 1945. My records from 
Mass, are: Framingham, Oct. 10, 1915, under bark; 
Sherborn, June 8, 1913; Hopkinton, June 7, 1925; Berlin, 
July 5, 1936, in fungus. Other records in my col- 
lection are: Mt. Washington, N. H., June 24, 1913; Mont- 
real Id., Quebec, taken by G. Chagnon; Edmonton and 
Leduc, Alta., F. S. Carr; Victoria Beach, Man., June 17, 
1923, C. S. Brooks. There are single records in both the 
New York and the New Jersey lists. — C. A. Frost, Fram-
