turn yellowish brown, a broad dark brown median stripe extending the 

 length of the sclerite ; scutum with the lobes brown, median space 

 brighter, more yellowish ; scutellum brown broadly margined with 

 yellowish ; postnotum dark brown. Pleurae broadly dark brown be- 

 coming much lighter colored on the sternum. Halteres rather long, 

 base of the stem pale, darkening into brown. 



Legs, coxae and trochanters light yellow, femora yellowish brown 

 darkening toward the tip, the apex broadly yellow, tibiae and tarsi 

 brown. 



Wings subhyaline, a brown quadrangular stigma, narrow brown 

 seams along the cord, at the tip of Sc and along Rs, on the outer de- 

 flection of cell 1st A/2 and less distinctly along most of the longitudinal 

 veins. Venation, (see plate XIV, fig. 1) Sci ending beyond the origin of 

 Rs, Sc2 also beyond Rs, its length about equal to Sc 1, basal deflection 

 of Cui about at the fork of M. 



Abdomen, tergites with the basal half of each segment dark brown, 

 the apical half abruptly yellow; sternites similar beyond the first seg- 

 ment.

Closely related to andicola Alexander, of Bolivia (Can. 

 Ent. ; vol. 44, pp. 362, 363 ; pi. 11, fig. h), differing in the lack 

 of lateral praescutal stripes, much more extensive brown pat- 

 tern on the wings, position of Sc2, etc. 



Dicranomyia tricincta, sp. n. 



Wings with a reticulated pattern, a supernumerary cross vein in 

 cell i?3 ; femora with three subequal, equidistant brown rings. 



Male. — Length, about 7-7.3 mm.; wing, 10.3 mm. Hind leg, femur, 

 8.8 mm. ; tibia, 9 mm. ; tarsus, 5.7 mm. 



Closely related to D. muscosa End. 1 of Ecuador, differing as follows : 

 Head rich brown without a yellowish tinge ; legs with the femora light 

 yellow with three broad equidistant brown bands, the first premedian, 

 the second postmedian, the last subapical, these annulations occurring 

 on all the legs, tibiae a little darker at the tip, two terminal tarsal seg- 

 ments brownish. In muscosa, the legs are bright greenish yellow, the 

 apical third of the femora yellowish, before the tip with a broad pale 

 grey ring, tibiae and tarsi bright brownish yellow. With muscosa it 

 agrees in its irregularly reticulated wing pattern, presence of a super- 

 numerary cross vein in cell R3, green cast to the body, etc.
