other lights almost white; scutum dark brown with a paler bloom along the 

 front margin ; scutellum dark brown with a diamond-shaped patch of gray 

 bloom in the middle ; postnotum brown. Pleurae black, the mesopleurje largely 

 covered with a silvery white bloom, a narrow brown stripe cuts across this 

 patch from the cervical sclerites to the scutellum. Halteres whitish, with the 

 knob brown. Legs with the coxae and trochanters brown, femora light yellow, 

 rest of the legs gone. Wings with the anterior half brown with rounded white 

 spots, a series of about eight in the radial cell, a large spot at the end of Sc, 

 extending caudad to the radial sector, other spots in cell 2nd /?, and R,. The 

 caudal cells of the wings are almost hyaline with scattered brown markings, 

 a brown suffusion along Cu and its fork, in cell ist A and on the anal angle of 

 the wing. Venation: Sc long, Sc^ at its tip; Rs long, much longer than the 

 very long deflection of ff^+j; inner ends of cells R^ and Cn^ almost in a line.

 Abdomen brown. 



Holotype, ?, Almaguer, March ii, 1912. 



Allotype, (?, with the type. 



The allotype has the femora much darker, brown, narrowly tipped 

 with yellowish. 



D. elcgantula approaches gloriosa Alex.^ (Guatemala) in its long 

 Sc and general coloration ; the venation, especially as regards the long 

 deflection of R^^r,, is very different; the pale color of the anal cells is 

 a conspicuous character. 



In regard to the patches of pollen occurring on the thorax of this 

 group of species, it should perhaps be stated that this varies consider- 

 ably in different lights and the student must take this factor into 

 accoimt. 



2. Dicranomyia cordillerensis new species. 



Subcosta long, thorax brownish yellow, wings pale brownish with scanty 

 brown spots. 



Female, length, somewhat shrunken, 7.6 mm.; wing, 11.2 mm. 



Rostrum and palpi dark brownish black ; antennas dark brownish black, the 

 flagellar segments oval, gradually more elongated toward the tip ; head gray. 



Mesonotal prsescutum shiny brownish yellow, becoming more brownish 

 behind ; scutum, scutellum and postnotum dark brown. Pleurae dull brownish 

 yellow. Halteres long, pale, knob darker. Legs, cox;e and trochanters dull 

 light yellow, remainder of the legs broken. Wings, pale brownish, cells C and 

 Sc rich yellow ; a conspicuous brown spot at the origin of Rs, a smaller one 

 at the tip of Sc, a very large stigmal blotch, indistinct scams on the crossveins
