Worker.—Antenne of 15 segments, first long and curved, not 
distally swollen; hairs as in soldier; body slender.

DESCRIPTIONS 
Adult.—Unknown. 
Soldier.—Head, antenne, and maxillary palpi pale yellow; head 
darker yellow anteriorly ; mandibles dark, transparent, brownish 
red; bases of mandibles, internal mandibular articulations, mar- 
gins of antennal foveole and “fontanelle tube” a light reddish 
brown; body white; anterior region of pronotum and the tarsi 
light yellow. Head long, parallel-sided, sides slowly rounding 
into rounded posterolateral corners; posterior margin straight; 
head dorsoventrally flattened with rounded sides (“thickly cylin- 
drical” of Holmgren). Forehead abrupt, making angle of about 
120° with the mandibles, laterally rimmed, centrally concave, 
dorsal rim concave; fontanelle, which is directed forward and 
distinctly visible internally as, a brown. tube, lies at posterior 
end of concavity; head considerably thickened anteriorly, thick- 
est just behind level of antenns. Mandibles short (0.825 mil- 
limeter long), strong, nearly straight, tips somewhat incurved, 
right untoothed, left with roughened cutting edge and two small 
and low but distinct teeth close together near the base. Labrum 
0.45 millimeter long and 0.225 millimeter broad, tongue-shaped, 
ending in a very slender, awl-shaped, hyaline tip; two large hairs 
at base of tip, beyond which the hyaline region has a length of 
0.09 millimeter. Anteclypeus very short, hyaline; medial ar- 
ticulations of mandibles at sides of postclypeus prominent and 
reddish in color. | 
Antenne of 15 segments, relatively thick, much longer than 
mandibles, reaching about to posterior margin of head with scat- 
tered large hairs and very numerous, short, distally directed, 
incurved smaller hairs; basal segment very large, swollen dis- 
tally; second cylindrical, larger than third; others larger than 
second, suborbicular to broadly oval; apical segment slightly 
Slenderer, long-oval; margins of antennal foveole projecting, 
reddish brown. Pronotum narrower than head, more than half 
as long as broad, slightly concave anteriorly and less so posterior- 
_ ly, broadest near anterior end, lateral margins receding gradually 
and rounding posteriorly into straight posterior border, slightly 
emarginate in center; sides depressed, anterior margin very 
’ slightly upraised; divided by middorsal longitudinal groove;
