Nephrotoma fuscipennis triflava, subsp. n. 
Male.—Length 11 mm. ; wing 9°8-10°4 mm. 
Female.—Length 15°5 mm. ; wing 13°6 mm. 
Close to typical fuscipennis, Karsch (Portuguese West 
Africa), differing as follows :— 
Second segment of the antenna dark brown ; in ig 
allotype female the entire scape is dark. Occiput with a 
conspicuous black triangular mark. Mesonotal postnotum 
light yellow with two large, rounded, black spots. Wings 
dusky black, the apices indistinctly paler. Abdomen with 
the first segment black ; second to fourth segments yellow, 
the apices narrowly black, broadest on the fourth segment ; 
remainder of the abdomen jet-black with the exception of 
the slender outer pleural appendages of the male which are 
obscure yellow. 
The female is referred to this species with considerable 
doubt. The head is largely jet-black, the vertex and part 
of the front orange-yellow. Lateral margins of the meso- 
notal prescutum very narrowly light yellow. Bases of the 
femora more extensively paler. The extreme basal lateral 
angles of the fifth abdominal segment are indistinctly red-
