CHARLES P. ALEXANDER 5 
Dicranomyia mulsa sp. n. 
Dark brown; head grayish, antennae black; kgs uniformly colored; wings 
dusky with a quadrate brown stignial spot; the radial sector sinuate near the 
tip, basal deflection of Cui long. 
Male. — Length, 7.6 mm.; wing, 10 mm. 
Female. — Length, 8 to 8.2 mm.; wing, 11.3 to 11.8 mm. 
Rostrum and palpi black. Antennae black, rather short, the flagellar 
segments oval. Head with a brownish gray bloom. 
Thoracic dorsum with the pronotum yellow on the sides, darker above; 
praescutum very deep reddish brown with dark brown stripes which merge 
insensibly into the ground color; these stripes cover most of the sclerite, the 
ground color being brightest before the pseudosutural foveae; scutum with 
the lobes deep liver-brown, the median area and the scutellum with a yellowish 
or grayish yellow bloom; postnotum dark brown medially, paler on the sides 
and here with a sparse grayish bloom. Pleura dull yellow with a broad inter- 
rupted pleiu-al stripe extending from the fore coxa to the sides of the post- 
notum. Halteres rather short, base of the stem pale, tinged with pale green, 
remainder of the stem and the knobs dark brown. Legs with the fore and 
middle coxae dark, hind coxae pale; trochanters brownish; remainder of the 
legs uniformly brown. Wings slightly sufi"used with darker; a large ciuadrate 
stigmal spot and a broad brown seam along the cord. Venation: (see plate 
I, figs. 1, 2) <Sc short, ending opposite the origin of Rs; Sd about one-half the 
length of Sci ; Rs sinuate near its tip ; basal deflection of Cui very long in the 
male, half as long again as Cu2 alone. 
Abdominal tergites dark brown, the basal sternites more yellowish, the 
apical sternites dark brown. 
The female sex is similar to the male but the basal deflection of Cui of the 
wings is not as long and cell Cui is consequently not so wide. 
Habitat. — Pern. Holotype, o^, Matucana, Peru, altitude 
7788 feet, July 14, 1914. (Parish coll.) Allotype, 9, topo- 
typic. Paratype, 9 , topotypic. 
This species is readily separated from related species by the 
deep liver-brown color and the peculiar wing-venation. 
Dicranomyia regifica sp. n. 
Color of the head and thorax light gray, unmarked; antennae dark brown; 
femora light brown, yellow at the tip; wings with an ocellate brown pattern; 
abdomen banded black and yellow. 
Male. — Length, 7 to 7.2 mm.; wing, 10 to 10.2 mm. 
Female. — Length, 6.8 mm.; wing, 10.3 mm. 
Rostrum rather short, light brown, palpi dark lirown. Antennae dark 
brown throughout, rather short. Head brownish gray. 
Thoracic dorsum dull opaque gray poUinose, the scutellum much paler, 
almost white. Pleura light gray. Halteres rather long, stem pale, the knob 
dark brown. Legs with the coxae and trochanters light yellow, femora pale
