ART. 14 TERMITES EEOM AMAZON BASIN SNYDER 17 



Holmgren's description ' is very meager, the characters merely 

 being given in a key, hence the species is herewith described for 

 comparison with other Syntermes. 



Another known species of Syntermes collected by Doctor Mann 

 is Syntermes chaquirnayeiisis Holmgren, found at Huachi, Bolivia; 

 soldiers and workers. 



Genus CORNITERMES Wasmann 



This genus is close to Syntermes Holmgren. In the soldier the 

 frontal tube is better developed than in Syntermes but on the other 

 hand the marginal teeth of the mandibles are not so well developed. 

 In 1912, Holmgren divided the genus Cornitermes Wasmann into 

 the subgenera Cornitermes {sensu strictore) Holmgren and Lahioter- 

 mes Holmgren. 



In Cornitermes {sensu strictore) the soldier has a long frontal 

 tube and short, broad labrum, without a sharply defined hyaline 

 apex; mandibles short and broad, left mandible with several fairly 

 well-developed marginal teeth. In Labioternies the soldier has the 

 frontal tube relatively short, labrum long and with a sharply de- 

 fined hyaline apex; left mandible with few, poorly developed mar- 

 ginal teeth. 



The winged sexual adults are separated: Ldbiotermes large eyes 

 and ocelli, latter close to eyes, antennae with 17 segments; Corniter- 

 r)ies {sensu sfrictin^e) medium large eyes and ocelli, latter more sepa- 

 rated from eyes, antennae 15 segments. The sexual winged adults 

 of Cornitermes show marked differences between the sexes. 



CORNITERMES (CORNITERMES) BOLIVIANUS. new species 



Winged, female adult. — Head dark castaneous brown, round fon- 

 taneUe hyaline, sub-oval raised spot in a depression, larger than an 

 ocellus, with few scattered long hairs. Post cljrpeus slightly lighter 

 than head, projecting, bilobed. Eye black, large, projecting, not 

 quite round, near lateral margin of head. Ocellus hyaline, sub-oval, 

 upper rim projecting, separated from eye b}^ a distance nearly equal 

 to the long diameter of an ocellus. 



Antenna yellow-brown, 1.5 segments, with long hairs; third seg- 

 ment sub-clavate, slightly longer than second or fourth segments; 

 segments become longer and broader toward apex; last segment 

 slender, sub-elliptical, pointed at apex. 



Pronotum same color as head, anterior margin straight, posteriorly 

 slightly eraarginate (broadlj'^ and roundly), anterior corners high,
