KALOTERMES (NEOTERMES) MANNI, new species 



Soldier. — Head lic^ht castaneous-brown, not quite twice as long as 

 broad, sides nearly parallel, slightly concave in middle, nearly flat, 

 slight slope and dej^ression at epicranial suture, Avhich forms two 

 lobes by a median division at its apex, with scattered long hairs. 

 Eye spot very small, white, ocellus and trace of frontal gland also 

 visible. 



Mandibles dark castaneous-brown to black, fairly elongate and 

 slender, with a high dorsal median ridge, giving a gouge-shaped 

 mandible, incurved at tips; left mandible with two sharp, pointed 

 marginal teeth at apical third, then a broad three-pointed molar 

 (with the central tooth the most prominent) extending to base; right 

 mandible with larger, sharp, pointed tooth at middle and a similar, 

 lower adjoining tooth. 



Gula narrow, width at middle one third as wide as at front. 



Labrum yellow-brown, slightly broader than long, rounded at 

 apex, with long hairs — two very long hairs at apex. 



Antenna yellow-brown, 13-14 segments, pubescent; third segment 

 sub-clavate, but not greatlj^ modified or differing from the other 

 segments, broader but not as long as (or slightly longer than) sec- 

 ond segment; fourth segment bead-like, shorter than (or same size 

 as) third segment; fifth segment slightly longer than fourth seg- 

 ment; from sixth segment on, segments become broader and much 

 more elongate (or only slightly longer and more or less bead-like). 



Pronotum yellow-brown, margins light castaneous, as wide as 

 head ; anterior margin shallowly, angularly concave ; posterior mar- 

 gin nearly parallel to anterior margin ; sides gradually and angularly 

 slope to posterior, anterior corners higher, posterior margin slightly 

 emarginate ; pronotum with long but scattered hairs. 



Legs white with tinge of yellow, tibiae and spines light castaneous, 

 femora swollen. 



Abdomen dirty grey, with tinge of yellow, wdth long hairs. 



Measurements. — 



Length of entire soldier, 9.00-10.50 mm. 



Length of head with mandibles, 3.50-5.20 mm. 



Length of head without mandibles (to anterior), 2.60-3.90 mm. 



Length of left mandible, 1.15-1.45 mm. 



Length of pronotum, 1.00-1.30 mm. 



Length of hind tibia, 1.20-1.50 mm. 



AVidth of head, 1.70-2.20 mm. 



Width of pronotum, 1.70-2.20 mm. 



Unlike in K. {N .) castaneus Burmeister, the hind femora are 

 swollen. Without the Avinged adult there is difficulty in placing sol- 

 diers of certain species of Kalotermes in a subgenus.
