Psyche 
[August-October 
Described from a single worker taken from the stomach of 
a toad (Bufo valliceps Weig., U. S. N. M. 46967) collected by 
Nelson and Goldman, July 28, 1894. 
The type lacks the antennal funiculi and portions of the legs, 
but is otherwise in good condition, with the pilosity well pre- 
served. Alfaria simuians Emery, the nearest species, differs in 
its shorter and stouter antennal scapes, in the entire absence of 
an impression between meso- and epinotum, in its larger size 
and lighter color. 
Leptogenys (Leptogenys) peninsularis, new species. 
Worker. — Length 7.5 mm. 
Head, excluding mandibles, more than one and one half 
times as long as broad, a little broader in front than behind, with 
feebly arcuate sides, broadly rounded occipital corners and 
straight border. Clypeus carinate at middle, the anterior pro- 
jecting triangular portion as broad as long and subacuminate at 
tip, the median lobes at middle of sides of front border low and 
rounded. Mandibles distinctly shorter than sides of head, seen 
from the front nearly straight, broadened apically, inner border 
of basal portion subcultrate and terminating in an inner small, 
broad lamellate triangle, blades strongly concave. Antennal 
scapes surpassing occipital angles by about three-eighths of their 
length, second funicular joint one and one-half times as long as 
the first, remaining joints shorter and slightly thicker toward 
apex, the terminal as long as the two preceding joints together. 
Eye about as long as its distance to border of clypeus. Pronotum 
as broad as long, broadest behind middle, sides convex, dorsal 
surface slightly convex. Mesonotum slightly longer than broad, 
with straight sides and posterior border. Meso-epinotal im- 
pression moderate. Epinotal base nearly straight in outline 
and about twice as long as the flat declivous portion, into which 
it broadly rounds. Petiolar node higher than long, anterior 
surface broadly convex, posterior surface flat, dorsum broadly 
rounding into anterior and narrowly into posterior surface; from 
above longer than broad, slightly widest behind, with sides 
feebly arcuate. Abdomen elongate; sting strong. Legs long and 
slender.
