 M.^. Venation : Sc long, extending far beyond the origin of Rs, Rs angular 

 and spurred at origin, almost straight beyond the angulation, deflection of R,^+^ 

 short. (See PI. 2, fig. i.) 



Abdominal tergites brown, sternites yellowish, the sclerites suffused with

Holotype, 9, Valle de las Papas, March 29, 1912. 



Agrees most closely with D. oniatipcmiis Blanchard (Chile), but 

 the wing pattern, as described for the latter, is different, the crossveins 

 not margined with darker. D. Hiicicollis Blanchard is a much smaller 

 species, with a dark lateral, thoracic stripe.

Three males and one female from Almaguer, March 11, 1912. 



The ventral lobes of the male hypopygium are conspicuous, yellow, 

 produced into a short, rounded protuberance near the base on the 

 inside and here with two long slightly curved, pointed spines ; lower 

 or cephalic side of this protuberance with a comb of long bristles. 

 Ventral projections of the pleura very elongate, cylindrical, the base 

 narrowed. Dorsal apical appendage of the pleura very stout, short, 

 strongly curved. Caudal margin of the 9th tergite concave.

About 40 specimens, both sexes, from Almaguer, March 11, 1912, 

 and Valle de las Papas, March 22 to 29. 1912. 



The 9th tergite of the male hypopygium has a deep median notch 

 on the caudal margin ; pleurae very short, the inner face beset with 

 stout spines, near the middle produced into a chitinized arm which is 

 provided with spines at short intervals and is tipped with long hairs; 

 pleura with two apical appendages, the dorsal one very short, about 

 as long as the pleura and strongly curved ; the ventral appendage very 

 large, fleshy, very much larger than the pleura, its inner margin near 

 the base with a small protuberance bearing two stout spines, on the 

 ventral margin cephalad of these spines are three large bristles ; pleura 

 with a large rounded lobe on the ventral side. (See Plate 3, fig. i.)
