Genus ORTHOPODOMYIA. Theobald. 



The Entomologist, Vol. XXXVII., p. 236 (1904). 



Head clothed with narrow-curved and forked upright scales ; 

 flat one at the sides. Palpi of five segments in the female ; long, 

 as long as half the proboscis ; in the male of four segments, three- 

 fourths the length of the proboscis. Thorax with narrow-curved 

 scales on the prothoracic lobes, mesothorax and scutellum. Wings 

 spotted. 



Allied to the genus Finlaya, Theobald, but differs in the 

 squamose structure of the head and scutellum. The female palpi 

 are noticeably very long. The hind legs, when the insect is 

 resting, are held straight out, close together, and quite close to 

 the surface upon which the fly rests, an abnormal attitude in the 

 Culicinae.
