shining; pronotum transversely*rugose, mesonotum, scutellum and mesopleurse 
coarsely and sparsely punctate, mesonotum also with a patch of longitudinal rugee 
near its posterior margin. Epinotum, petiole and postpetiole opaque, densely 
punctate. Gaster with fine piligerous punctures. 
Hairs more abundant than in the soldier, but more appressed, short and incon- 
spicuous on the appendages. 
Head ferruginous red, borders of mandibles and an ocellar spot black. Re- 
mainder of body deep castaneous brown, pleuree and posterior borders of gastric 
segments paler; antenne and legs brownish testaceous. Wings grayish hyaline, 
with pale brown veins and dark brown stigma. 
Male. The head is opaque and densely longitudinally rugulose and punctate 
(shining in the male zerophila), the veins of the wings are somewhat darker and the 
petiolar node is higher and re sede more acute in profile than in me type of the 
species. 3 
Described from numerous specimens of all four phases taken at Pasadena 
and Lakeside, Southern California, during late November, 1910. The col- 
onies were found on the dry open hills in small crater nests, the periphery 
of which was often covered with discarded chaff and seeds, proving that the 
species 1s a harvester. Only a few soldiers were found in each nest. The 
presence of males and winged females in late November shows that these 
phases are probably retained in the nests throughout the winter as in 
Prenolepis imparis, Camponotus americanus etc., and that the nuptial flight 
as in these ants probably occurs in the very early spring. 
23. Pheidole vinelandica longula Emery var. castanea var. nov. 
Differing from the typical longula in its much darker coloration, the body of the 
soldier being rich chestnut brown, the anterior border of the gaster, the posterior 
border of the head, the cheeks, disks of mandibles, clypeus, legs, antenne, pleurz and 
epinotum somewhat paler and more reddish. The coloration of the worker is similar, 
except that the posterior portion of the head and the anterior portion of the gaster 
are dark like the remainder of these regions. 
Described from six soldiers and thirteen workers taken in Miller Cafion, 
Huachuca Mts., Arizona, at an altitude of 6000 ft. 
24. Pheidole vinelandica cerebrosior subsp. nov. 
Soldier. ike the typical vinelandica in color, sculpture and pilosity, but the 
head decidedly larger though not proportionally longer, and with the postpetiole 
twice as broad as the petiolar node and produced on the sides as pointed conules. 
Worker. Differing from the worker of the typical vinelandica only in having the 
fine punctuation of the thorax and pedicel stronger and these parts therefore more 
opaque and the erect hairs somewhat less abundant and more obtuse at their tips.
