210 PROCEEDINGS OP THE NATIONAL MUSEUM. vol.55. 



TRIGONA CURRIEI Cockerell. 



Worker. Length about 3 mm., robust, black; head large and 

 quadrate: mandibles and base of scape red; clypeus with a median 

 groove ; whole body polished and shining ; cheeks very broad ; tegulae 

 fuscous; wings dilute brownish, stigma pale with a duslry margin; 

 legs obscurely reddish; abdomen short and broad, the first segment 

 very obscurely more or less reddish. Related to T. magrettii Friese, 

 but easily separated by the brownish wings. The head also is quite 

 broad. 



Mount Coffee, Liberia, April, 1897 (E. P. Currie). 



bh. Wings clear hyaline, a little milky. 



6«. Mesothorax polished ; antennae low down on face. 



TRIGONA MAGRETTII Friese (Old Calabar). 

 TRIGONA BOTTEGOI Magretti (Somaliland). 



The T. magrettii was determined by Friese; the T. hottegoi came 

 from the Magretti collection. In spite of the widely different 

 localities, I can not see any difference. Apparently T. magrettii falls 

 as a synonym. 



65. Mesothorax dull ; labrum pale or yellow. 



7(2. Abdomen brown, hind margins of segments pallid ; " eyes red " 

 (Friese). 



TRIGONA GRIBODOI Magretti. 



Three specimens are from Luebo, Congo (D. W. Snyder). 

 7&. Abdomen red basally and black apically ; " eyes black " 

 (Friese). 



TRIGONA BRAUNSI Kohl. 



Very closely allied to the last. 



45. Species not minute. 



8(2. Abdomen entirely black or piceous; mesothorax not polished; 

 wings dilute brownish. 



9«. Larger, anterior wing about 6 mm. long ; hind tibia very broad ;

TRIGONA TOGOENSIS JUNODI Friese. 



95. Smaller, v^dth light face marks. 



10(2. Light face marks consisting of triangular supraclypeal mark, 

 lateral bands along orbits, and transverse clypeal band having a 

 median vertical process ; tubercles light. 



TRIGONA LENDLIANA Friese. 



105. Light face marks confined to broad band on lower margin of 

 cljnpeus, and small obscure lateral marks.
