Genus Megarhinus. 139 



creamy lateral patches to the other segments ; venter creamy 

 yellow, except for the black apex. 



Legs uniformly black with metallic violet scales ; fore ungues 

 unequal, the larger uniserrated, of the hind legs also unequal, and 

 apparently simple, those of the hind small, much curved, equal 

 and simple. 



Wings small, scales brown, those at the base showing- 

 violet reflections : the first sub-marginal cell so minute that it is 

 scarcely perceptible to the naked eye ; second posterior cell fairly 

 large and broad about half the length of its stem ; the third long 

 vein carried well past the cross-veins as a scaled vein ; super- 

 numerary cross-vein about three times its own length nearer the 

 apex of the wing than the mid, mid cross-vein small, joining the 

 posterior cross- vein which is about five times the length of the 

 mid. Halteres dull ochreous. 



Length of body 6 mm. • of palpi 4 mm. 



Habitat. — Yatiyantota, Ceylon (E. E. Green). 



Time of capture. — March (1902). 



Observations. — Described from a single perfect $ . Whether 

 it will come in Megarhinus or Toxorhynchites it is not possible to 

 say, but I fancy it is a true Megarhinus. Its small size will at 

 once separate it from all known members of the two genera. It 

 is also peculiar in having spines or bristles in the place of a caudal 

 fan and in the very minute first fork-cell. The abdomen shows 

 all manner of metallic and colour reflections.
