Length 13 mm. 6. 



Kandy, July. 



In colouration this species resembles closely F. ruflpes, but the 

 pleurae are not marked with yellow, the hind coxae are red, without 

 black or yellow, and the face wants the black central mark. Other- 

 wise the two may be separated thus : 



Apex of metanotuui not raised, near the apex armed with two 

 stout teetli or tubercles, which are enclosed bj- the yellow 

 apical band ; the apical transverse band as long as the basal 

 cejitral line, this being narrowed towards the base ; pleune, 

 immaculate, not strongly or closely striated ; the base of the 

 first and the wliole of the apical two segments, white, bituber- 

 culata. Cam. 



Apex of metanotum raised transversely, not tuberculated : the 

 apical transvei-se Hne narrow, tlie longitudinal one widest at 

 the top, plem'ae marked with yellow, distinctly striated face : 

 the base of the first abdominal segment not yellow ; the 

 apical two segments only yellow at the apices, rufipes. Cam. 



There is a triangular mark on the centre of the metanotum, the 

 narrow end at the apex ; the striae on it are irregular and run into 

 reticulations. The striation on the front is not very strong. Face 

 yellow. Clypeus black, with a yellow mark, transverse, rounded at 

 the sides in the centre. Legs red ; the hind trochanters black. Areo- 

 let not very large, almost square (smallei' than in rufipes, which 

 receives the recurrent nervure shortly behind the middle).
