96 Psyche [June- September 
Var. semirex var. nov. 
Workers media and minor. Length 8-11 mm. 
Very similar to rex, but the appressed pubescence is 
almost lacking on the thorax and petiole, though well de- 
veloped on the head and dorsal surface of the pronotum. 
The pronotal spines are very short and obtuse, the petiolar 
scale with blunt, broadly rounded border as in rex. 
Described from five specimens taken by Dr. J. Bequaert 
at Corocito, Honduras. 
Var. cualatensis var. nov. 
Worker maxima . Length 12-14 mm. ; head 5 mm. x 5 mm. ; 
hind tibia 5.2 mm. 
Head entirely red, shining, especially on the sides and 
clypeus ; mandibles black. Pronotal spines as in rex. Petiole 
with sharp, compressed dorsal border, seen from behind 
broadly rounded, entire, with pronounced lateral angles. 
Appressed pubescence dull, rather ochraceous yellow, less 
abundant on the sides of the thorax than in rex. Hairs 
abundant, but distinctly shorter, especially on the epinotum 
and gaster, fulvous yellow. Legs somewhat reddish. 
Workers major, media and minor. Length 8-12 mm. 
Like the maxima, except for the smaller head. This is 
more or less reddish in the major but black in the smaller 
phases. Meso- and epinotum strongly compressed dorsally, 
as is also the border of the petiolar scale.

Var. zacapensis var. nov. 
Worker maxima. Length 13-15 mm. ; head 5x5 mm. ; hind 
tibia 5.5 mm. 
Resembling the maxima of cualatensis but with the head 
black. Pronotal spines broad and obtuse, somewhat flat- 
tened. Dorsal border of petiolar scale blunt, not compressed,
