Genus POLYLEPIDOMYIA. Theobald. 

 Ann. Mus. Nat. Hung. III., p. 118 (1905). 



Head clothed with flat scales over all the front, sides and centre ; 

 a small area behind of narrow-curved scales and some upright 

 forked ones. Palpi short but moderately developed in the ? . 

 Antennae of ? pilose, verticillate hairs long. Proboscis 

 moderately long. Thorax clothed with large, narrow-curved 

 scales ; prothoracic lobes with small flat scales ; scutellum with 

 flat scales ; metanotum nude. Apex of abdomen very bristly. 

 Wings with Gulex- venation and scales. 



This genus comes apparently in the Aedinae. Both palpi 

 and proboscis show variation in relative lengths in all the 

 specimens examined. 



The nearest related genera seem to be Dendromyia and 

 Phoniomyia, but the absence of metathoracic chaetae and the 

 different wing scales and cephalic ornamentation will at once 

 separate it.
