Psyche 
[June- Sept. 
Strumigenys (Cephaloxys) reflexa, sp. n. 
Worker: (PL 3, fig. 4) : Length, 1.75-1.85 mm. 
Head robust; exclusive of mandibles, 2 to 2.2 times as 
long as the greatest width of the clypeus, 1.3 times the 
greatest width across the occipital lobes; clypeus broadly 
rounded laterally, more narrowly rounded in the middle of 
the anterior border, the sides strongly scalloped; anterior 
portion of the head with a very broad distinct depression 
extending from the anterior portion of the clypeus to be- 
tween the frontal carinae ; occipital lobes broadly and rather 
evenly rounded ; posterior border shallowly excised. Man- 
dibles % the length of the rest of the head, moderately 
robust, the external borders gently convex ; the pair of basal 
teeth stout, just hidden when the mandibles are closed, suc- 
ceeded by a toothless space which is equal to i /3 the length 
of the mandibles anterior to them, the toothless space fol- 
lowed by 4 or 5 pairs of rather short acute teeth which meet 
the apical series of numerous fine denticles. Antennal 
scapes rather sharply but not strongly angulate basally, % 
as long as the funiculi; fourth funicular joint decidedly 
shorter than the first, the terminal joint almost half again 
as long as the remainder of the funiculus. 
Thorax as in S. puchella; mesoepinotal suture distinct, 
slightly constricted. Epinotal spines broad and thin ; infra- 
spinal lamellae wide, broadly expanded ventrally. 
Head, thorax and petiole reticulate-punctate, subopaque; 
head, especially on the dorsal posterior half coarsely tuber- 
culate. Meso- and meta pleura, dorsum of the postpetiole 
and gaster, smooth and shining ; first gastric segment with 
numerous coarse longitudinal striae on the basal 14 . 
Clypeus with a few, short, irregular squamose hairs on 
the border; projecting from the edge of the clypeus on each 
side are 3, occasionally 4, long coarse squamose hairs which 
are strongly curved posteriorly; the rest of the dorsal sur- 
face of the head with more numerous erect, curved, narrow 
squamose hairs, curved predominately posteriorly ; antennal 
scapes with 6 or 8 erect, clavate hairs on the outer border, 
most of which are slightly curved toward the bases of the 
scapes. Hairs on thorax sparse, irregular in length, erect, 
slightly enlarged apically. Petiole, postpetiole and gaster
