or fifth; in specimens of G. nordenskioldi Holmgren from Britisli 

 Guiana there are plainly 12 segments to the antennae. 



Pronotum pale yellow, saddle-shaped, with fairly large, raised 

 up front, anterior margin not emarginate (pi. 1, fig. 7). 



A comparison was made of one soldier and workers of hrevipilosus 

 collected by AY. M. Mann at Ivon, Bolivia, in February 1922, and 

 soldiers and workers of 7iordenskidldi ? collected at Kartabo, British 

 Guiana, by Alfred Emerson. The soldier of hrevipilosus is smaller, 

 has denser, shorter hairs on the head, and shorter, more curved 

 mandibles. A larger portion of the pronotum is raised up and the 

 anterior margin is not emarginate, as is the case in the soldiers of 

 'fiordensJi'loldl from Kartabo and Holmgren's description of the type 

 {Holmgren, 1906) ; the description of the type also states that the 

 liead is fairly thickly pubescent; the specimens of nordenskidldi ? 

 from Kartabo have a narrower head than Holmgren's type and may 

 be a new species. Specimens from Panama seem to be nearer to 

 Holmgren's tj'pe. The following measurements show these differ- 

 ences : 



' The worker of hrevipilosus has denser, longer hairs; both species have 13 segments to the antenna. 



Type locality. — Ivon, Bolivia. Described from a single soldier 

 and several workers collected by W. M. Mann, in February, 1922, at 

 the type locality.

Genus MIROTERMES Wasmann 



In 1912, Holmgren divided the genus Miroter7nes Wasmann into 

 several subgenera. Of the.se subgenera, two were found in Bolivia by 

 Doctor Mann, namely Mlrotennes {sensu strictore) Holmgren and
