New Forms of Aphsenog aster treatse 
9 
mandibles lVs times the width. Scape shorter, 1 1-15 times 
the length of the head. 
Sculpture coarser, gaster duller. Mesoscutum striated 
above longitudinally; on the mesoscutellum these ridges 
curve into cross striations posteriorly. Transverse striations 
of epinotum regular, not reticulate. Petiole rugose, reticu- 
lations becoming somewhat diagonally striated behind. 
Area between the reticulations punctate. Keel on the ven- 
tral surface sharp. Anterior dorsum of postpetiole reticu- 
late, somewhat coarser and transversely striated behind. 
First gastric segment finely striated longitudinally at the 
base, merging into fine reticulations and fading out pos- 
teriorly. 
Hairs relatively shorter and more abundant. 
Color ferrugineous to fusco-ferrugineous, lighter speci- 
mens with darker parapsidal furrows. Metanotum, teeth 
of mandibles, area between ocelli, margins of thoracic 
sclerites, bands on the apices of gastric segments, fusco- 
ferrugineous ; when completely retracted the lighter bands 
are concealed. 
Male. Length 5 mm. 
Differs from the male of A. treatse as follows: 
Irregularly transverse ridges of the epinotal declivity 
fewer. Epinotal spines variable, 2 sometimes reduced to low 
rounded protuberances. Thorax piceous, femora and tibiae 
darker also. 
These ants were collected by the authors in open woods 
(mostly Quercus marilandica Muench.), where the soil was 
a sandy loam. 
Oklahoma: Poteau. VI-17-’29. Numerous workers, 
1 dealated female, 3 winged females, 4 males, and a few 
larvae and pupae. On a steep slope in the soil and under 
dead leaves beside a stone. (Type nest.) 
Oklahoma : Poteau. VII-16-’22. Small colony under a 
stone on a steep hillside. 
Texas: Ivanhoe (Fannin County) . VI-27-’29. Numerous 
workers, 8 dealated females; 7 winged females, 3 males, a 
few larvae and pupae. In the buried end of a small decayed 
branch.
