Genus CYLINDROTERMES Holmgren 



The genus Cylindroterm.es includes but the single species nordens- 

 kioldi Holmgren, described from soldiers and workers collected only 

 once by Holmgren in the stump of a banana tree at Tuiche, Province 

 de Caupolican, Bolivia, May, 1904 (Holmgren, 1906). This genus 

 comes in the Aniitermes group and is near the genus G ephalotermes 

 Silvestri, according to Holmgren (1912). 



A new species from Bolivia, C. hrevipilosus^ is hercAvith described; 

 it is close to nordenskioldi Holmgren but is strikingly characterized 

 by dense short hairs on the head of the soldier. 



Species collected by A. Emerson at Kartabo, British Guiana, and 

 determined by Emerson as nordenskidldi may be a new species. 

 Specimens from Barro Colorado Island, Canal Zone, and Rio 

 Chinilla, Canal Zone, Panama, appear to be nearer to Holmgren's 

 type; the head is broader than Emerson's specimens and the mandi- 

 bles longer and stouter; antennae and pubescence similar. 



CYLINDROTERMES BREVIPILOSUS, new species 



Soldier. — Head straw-yellow, elongate, sides nearly parallel, nar- 

 rowed towards posterior, with dense short hairs (but few long 

 hairs) ; mandibles black with reddish tinge, stout, base yellow-brown, 

 short and curved. The widtli of the gula at the middle is more 

 than half the width at the front. The labrum is of different shape 

 than in nordenskidldi. 



Antenna light yellow, 11 to 12 segments, pubescent; if 12 segments, 

 third segment indistinct, very small; fourth shorter than second
