CHARLES P. ALEXANDER 17 
A male and a female from Alaousi, Ecuador, altitude 9450 feet, 
June 18, 1914; one male and one female from Huigra, Ecuador, 
altitude 4500 feet, June 13 to 16, 1914; collected by Parish. 
The genitalia of the male differs somewhat from the descrip- 
tion of the typical Costa Rican specimens, but I do not think 
at this time that the material represents a distinct species. 
These differences are: the two chitinous points at the tip of the 
recurved ventral gonapophyse are longer; the fleshy lobe near 
the middle of the intermediate apical appendage is not tooth-like 
or conical as in typical recurvata, but is truncated at the apex 
which bears two large hairs. 
Gonomyia (Leipoueura) near alexanderi Johnson 
1912. EUiplcra alexanderi Johnson, Psyche, xix, p. o, fig. 6. 
Abundantly represented in the collection from Lima, Peru, 
altitude 500 feet, collected by Parish; both sexes are represented 
in the material which is dated from August 4 to August 21, 1914. 
This fly probabh^ represents a new species closely related to 
alexaiideri. 
Subgenus Gonomyia Meigen 
Gonotayia (Gonomyia) jejuna sp. n. 
Basal segments of the antennae yellow; a conspicuous dark brown pleural 
stripe; wings with cell 1st Mi open. 
Male. — Length, 3.8 to 4 mm.; wing, 5 to 5.3 mm. 
Female. — Length, 4.4 to 4.6 mm.; wing, 5.5 to 5.7 mm. 
Rostrum and palpi very dark brown. Antennae rather long and slender, 
in the male if bent backward, extending beyond the wing-root, the scapal 
segments orange-yellow, flagellar segments oval, dark brown with a rather 
dense silvery pubescence. Head light yellow with darker markings on the 
vertex. 
Thoracic praescutum brown with a sparse yellowish brown bloom, the scler- 
ite darker in front but without distinct stripes; scutellum and postnotum 
darker, plumbeous. Pleura pale yellowish white with a broad dark brown 
stripe from the sides of the pronotum to the base of the halteres. Halteres 
brown, the knobs darker. Legs dull yellowish, the femora, tibiae and tarsi 
more brown. Wings nearly hyahne, the veins bro\ra. Venation: (see plate 
I, fig. 8) Sc short ending far before the origin of Rs; R-i+n shorter than R^ alone; 
Rs in a fine with ^4+5, the deflection of the latter being obhterated; cell 1st Mj 
open due to the atrophy of the outer deflection of Ms; basal deflection of Cui 
at the fork of M. 
Abdominal tergites dark brown, the basal sternites paler, more yellowish. 
Hypopygium (see plate IV, fig. 1) with the pleura (a) rather short and stout, 
cylindrical, the inner dorsal angle with a fleshy lobe projecting dorsad and in- 
TRANS. AM. ENT. SOC, XLII.
