apical segment minute, penultimate one large, swollen apically 

 and truncated ; the ante-penultimate broad apically, becoming 

 narrower and swollen again basally, two basal constrictions- 

 looking almost like joints. The apex of the penultimate segment 

 is studded with round spots. Palpi long in the male, longer 

 than the proboscis, the two apical segments short, rather 

 swollen, also the apex of the ante-penultimate ; hair-tufts- 

 rudimentary. 



Thorax with narrow-curved scales ; scutellum with small flat 

 scales on the median lobe, narrow-curved ones on the lateral 

 lobes. 



This genus comes near Stegomyia, but differs in having 

 narrow-curved scales on the centre of the head and on the lateral 

 lobes of the scutellum.
