Described from six soldiers, collected 
with nymphs in a decaying log in 
jungle, at the type locality, by I. 
Molino and T. E. Snvder on February 
22, 1924. 
Type, soldier. —Cat. No. 27266, 
U. S. National Museum. 
Neotermes holmgreni Banks. 
slightly longer and broader than second 
and much longer and broader than 
fourth; fifth longer than fourth, seg¬ 
ments becoming longer toward apex; 
last segment slender, shorter and sub¬ 
elliptical. 
Pronotum gray-white with pale yel¬ 
lowish tinge, darker (brownish) on 
margins, anterior margin broadly, 
roundly but shallowly emarginate (con¬ 
cave), posterior margin convex, sides 
rounded, anterior corners rounded and

Measurements. —Length of entire 
soldier: 9.5-11.5 mm. Length of head 
with mandibles: 5.1 mm. Length of 
head to anterior margin: 3.3 mm. 
Length of left mandible: 1.8 mm. 
Length of pronotum: 1.2 mm. Length 
of hind tibia: 1.2 mm. Width of head: 
2.1-2.2 mm. Width of pronotum:

Described from a series of soldiers 
collected with nymphs at the type 
locality (Taboga Island, Republic of 
Panama) by the writer on February 17, 
1924, in a decaying branch on the 
ground. These specimens are in the 
collection of the United States National 
Museum. No winged adults were col¬ 
lected with these soldiers. The winged 
adult was described by Nathan Banks 
in 1918, and these are the first soldiers 
collected, this caste being hitherto un¬ 
known. Specimens of soldiers from 
Ancon Hill, Canal Zone, show variations 
in mandibular teeth, pronotum, etc. 
Soldier. —Head light castaneous 
brown, paler posteriorly, with reddish 
tinge anteriorly, elongate, sides slightly 
concave, broader anteriorly, frontal 
slope with lobed epicranial suture, eye 
spot hyaline, elongate, parallel to 
frontal slope, head with scattered long 
hairs. Gula slender in middle. 
Mandibles black, base reddish, broad 
at base, more slender toward apex; 
incurved at apex; right mandible with 
two sharp, pointed teeth near base, 
slightly crenulate toward apex; left 
mandible with three ‘‘molar” (double) 
teeth with first teeth more prominent. 
Antennae light brown, paler anterior¬ 
ly, not as long as mandibles, of 13 
segments, with long hairs; third seg¬ 
ment slightly modified, subclavate, 
Kalotermes (Glyptotermes) angustus, 
new species. 
Winged adult. —Head shining, dark 
castaneous brown, lighter below the 
eyes, longer than broad, sides parallel, 
with scattered long hairs; eyes black, 
not round, large, slightly projecting, 
separated from lateral margin of head 
by a distance less than half an eye 
diameter; ocelli hyaline, small suboval', 
close to and at an oblique angle to eye. 
Antennae light brown, of 12 segments, 
with long hairs; segments becoming 
longer and broader toward apex; 
third segment subclavate, longer than 
fourth but shorter than second; last 
segment longest, apex appearing to be 
somewhat obliquely truncated.
