Described from a perfect male and female. It forms a very 

 marked species, the ornamented wings and marked head and 

 thoracic ornamentation at once separating it from any other 

 mosquito that I know of. The colour of the head and thoracic 

 markings vary according to the light especially under the micro- 

 scope, in some lights the scales show blue, in others almost 

 silvery white. The same applies to the pale scales on the wings.
