KALOTERMES APPROXIMATUS Snyder. 



Soldier (pi. 1, fig. 1). — Head yellowish-brown (light castaneous), 

 darker anteriorly, one and one-half times as long as broad, sides 

 parallel to slightly concave, with few, scattered, light yellow, long 

 hairs; front of head slopes anteriorly, with V-shaped depression. 



Antennae pale yellowish, 13 segments, reach tip of mandibles when 

 mandibles are crossed, pubescent; third segment yellow-brown, sub- 

 clavate, not quite as long as fourth and fifth segments together 



Eye hyaline, white, round to oval; ocellus visible above eye spot. 



Labrum yellow-brown, broader than long, hardly round at apex, 

 with long hairs. 



Mandibles black, shining, reddish-brown at base, nearly as long as 

 width of head; broad at base, pointed and incurved at tip; right 

 mandible with two short, pointed, subequal marginal teeth near base, 

 left mandible with three broader blunt marginal teeth on lower two- 

 thirds, the median tooth being broadest (molar). (See figure.) 



Gula slender, over twice as broad at front as at middle. 



Pronotum dirty white with pale yellowish tinge, wider than head, 

 less than twice as broad as long, roundedly and fairly deeply concave 

 anteriorly, anterior margin not dentate as in K. marginipennis 

 Latreille; sides slope roundedly to posterior, posterior margin 

 convex. 



Legs pale yellow, tarsi yellow, legs short, hind femora swollen, legs 

 with short hairs. 



Abdomen dirty white gray, with tinge of yellow, with light yellow 

 long and short hairs. 



Measurements,— Length, of entire soldier, 7.50-7.75 mm.; length of 

 head with mandibles, 3.3-3.7 mm.; length of head without mandibles 

 (to anterior margin), 2.2-2.4 mm.; length of head without mandibles 

 (to tip of labrum), 2.6 mm.; length of pronotum (at corners), 1.10- 

 1.15 mm.; length of left mandible, 1.35-1.40 mm.; length of hind 

 tibia, 1.1 mm.; width of head, 1.40-1.55 mm.; width of pronotum, 

 1.6-1.7 mm. 



Species close to marginipennis but differs in antenna, mandibles, 

 and pronotum. The winged adult is unknown. I described this 

 species in 1920,* but this more complete description and figure is 

 desirable.
