A SYNOPSIS OF THE LARVAEVORID FLIES OF THE 
GENUS EUDEJEANTIA? 
By Curtis W. Sasrosky 
Tue large and heavily spined flies of the tribe Dejeaniini, which 
reach their greatest development in the Andean mountains, have al- 
ways attracted the attention of students of the Diptera. In an at- 
tempt to identify a number of specimens from Colombia, it proved 
so extremely difficult to name and to decide upon the status to be 
accorded the various forms of H'udejeania Townsend that a study 
was undertaken of the rather considerable material at hand. In the 
interpretation of older descriptions, it is necessary for the most part 
to use color distinctions, but I am convinced from a study of the 
available material that certain of these may be relied upon in this 
group. 
Genus EUDEJEANIA Townsend 
Hudejeania TownsEND, Proc. U. S. Nat. Mus., vol. 43, p. 334, 1912. Two species; 
type by original designation, H. subalpina Townsend. 
Eudejeania, sensu lato, ENGEL, Zool. Jahrb., Abt. Syst., vol. 48, pp. 277-292, 1920. 
Key to seven species and four varieties; genotype cited as H. pallida (Robi- 
neau-Desvoidy), with swbalpina, a variety. 
Budejeania TownseEnp, Rev. Ent., vol. 1, p. 163, 1931. Discussion of the genotype 
and the Mexican and Central American species. 
Eudejeania TowNsEND, Manual of myiology, pt. 8, pp. 78-79, 1939. Generic 
diagnosis; said to range in many species from Mexico to Bolivia, at high 
elevations. 
1The material upon which this study was based is contained in the collection of 
the U. 8. National Museum and in an interesting collection of flies kindly submitted 
for determination by Hernando Osorno Mesa, Instituto de Ciencias Naturales, Ciudad 
Universitaria, Bogota, Colombia.
