apex, about as far from it as twice the distance between the tips 

 of the third and fourth veins. First vein bare, third bristly ahnost 

 to tlie cross vein. 



Length, 11 mm. 



Not represented in tlie United States National Museum. 



Townsend's Rcdmondia umhuasi was described from a single , 

 female, but the Museum possesses three males and an additional 

 female from Huascaray Ridge, Jaen Province, Peru, September 21 

 and 22 (Townsend). The species is very close to tetraptera^ show- 

 ing only three differences that I can see. The wings are considerably 

 infuscated. especially the crossveins; the male has a pair of long 

 |)arallel upright apical scutellars, the tips of which curve forward; 

 the abdomen of the male has a somewhat more contrasting pattern, 

 with better defined subsilvery triangles on anterior lateral part of 

 I lie second, third, and fourth segments. The female of tetraptera 

 is unknown, but that of mnihua-n has no apical scutellars and the 

 abdominal pattern Avhile similar to that of the male, is more tessel- 

 lated. The male genitalia have been carefully compared and seem 

 identical. It may yet proA'e that uruh/uxisi is merely a subspecies of 

 tetraptera. 



The genus Lepklodexia belongs to the family Sarcophagidae, as 

 indicated by Brauer and Bergenstamm.
