Female. Length 4 lines. The anterior margin of the clypeus 

 angulated, the middle subcarinated, with the sides oblique, the 

 anterior margin rounded ; the clypeus, sides of the face, man- 

 dibles, and base of the flagellum, rufo-ferruginous ; thorax fre- 

 quently entirely fuscous above, but sometimes with three fuscous 

 stripes ; the legs ferruginous, with the apical joints of the tarsi 

 fuscous. Abdomen : the base and apex usually more or less 

 ferruginous. 



Worker. Length 3-31 lines. Resembles small dark specimens 

 of F. rufa ; but the antennae are more slender, as well as the 

 legs ; the facial area is not shining ; the thorax above, and the 

 tibiae and tarsi above, more or less fuscous ; the apical margins 

 of the segments of the abdomen are more or less distinctly 

 rufo-piceous, the extreme apex pale ferruginous. 



Male. Length 3 lines. Very closely resembles that of F.fusca, 

 but has the scale of the abdomen transverse, and emarginate 

 above its entire width, the angles of the emargination obtuse ; 

 the antennae are more slender, the scape longer, and the face 

 rather less produced before the eyes than in F.fusca.
