Described from two soldiers and one 
dealated adult collected with nymphs 
at the type locality by I. Molino and 
T. E. Snyder on February 21, 1924, 
in a decaying branch lying on the 
ground in moist jungle. This species 
was named in honor of Dr. Thos. 
Barbour, of the Museum of Com¬ 
parative Zoology, Cambridge, Mass.

riorly, rim elevated, front deeply 
bilobed medially with a wide U-shaped

ginal teeth; right mandible with two

shaped, becoming longer and broader 
toward apex, with long hairs; third 
segment ringlike, shorter than second or 
fourth segments; last segment slender, 
subelliptical, pointed at apex. 
Pronotum light yellow-brown, darker 
on margins, margins deeply roundly 
emarginate, corners high anteriorly and

tered long hairs (fig. 5, c).
