Subgenus Velocitermes Holmgren 



This subgenus of Nasiitiferines Banks was established by Holm- 

 gren in 1912; only four species have been described, all being from 

 America, namely, N. (F.) antUlaruni Holmgren from San Domingo, 

 Jieteropterus Silvestri from Paraguay and Brazil, velox Holmgren 

 from Bolivia and Peru, and heehel Emerson from British Guiana. 

 The soldiers are long-legged and rapid moving.

Whiged adult. — Head blackish, shining, not nuich longer than 

 broad, flattish but with slope anteriorl}^, rounded posteriorly, with 

 dense long hairs. Fontanelle linear, constricted at the middle, two

Antenna yellow-brown, 15 segments, pubescent ; third segment sub-
