4. Crematogaster lineolata Lay, subsp. coarctata Emery. 
Several workers indistinguishable from the typical Califor- 
nian form. 
5. Stenamma (Aphzenogaster) patruelis Forel, subsp. bakeri 
subsp. nov. 
Workers from two eolonies. Whole ant shining, the sculp- 
ture on the head being confined to sharp and rather irregular 
longitudinal rug, with very indistinct interrugal sculpture. 
Upper surface of thorax glabrous, meso and metapleure with a 
few longitudinal, the basal surface of the epinotum with a few 
transverse rugz. Pro-and mesothorax curvex, hemispherical, 
basal surface of epinotum evenly curvex im profile. Epinotal 
spines very small, acute, much farther apart than long. Body 
and appendages yellow or yellowish red, except the following 
portions: There is a large brown blotch on the vertex; the 
inner borders of the mandibles are black; the summits of the 
nodes of the pedicel, the gaster with the exception of the in- 
. elsures, and in some specimens also the middle portions of the 
femora and tibizw, more or less infuseated or black. 
Forel and Emery regard patruelis, originally described from 
the Island of Guadalupe, as a subspecies of S. subterraneum 
Latr., but I am inclined to separate it as a distinct species 
on account of the peculiar shape of the thorax. In subter- 
raneum and its western form, occidentalis Em., the pro-and 
mesonotum are less hemispherical and the basal surface of the 
epinotum is straight or even somewhat concave in profile. 
There are so many forms of subterraneum in the western states 
that it will be advantageous to regard patruelis as a distinet 
species, though it must still be placed in the subterraneum 
group. 
S. bakeri is a very striking form on account of its glabrous 
surface, yellow color and the conspicuous blotch on the vortex. 
6. Stennnama (Messor) andrei Mayr. 
A single worker of this species, which seems to be oiher 
abundant in California and Nevada. 
CAMPONOTIN 2. 
7. Camponotus maculatus Fabr., subsp. vicinus Mayr., var. 
nitidi ventris Emery. 
One soldier and four workers. 
8. Camponotus hyattii Emery, var. bakeri, var nov. 
Media. Length, 5.5 mm. 
Differing from the typical form in coloration which is like 
that of C. marginatus Latr., subsp. discolor Emery, except that 
the basal two-thirds of the first gastric segment are also red 
like the head thorax and appendages. The seculpturing of the 
whole body is quite as sharp as in marginatus so that the sur-
