Metanotum yellow; pleurae whitish with a tinge of brown. Halteres, pale. Legs, 

 brownish-yellow throughout. 



Abdomen, dark brown, pleurae somewhat paler; genital segment yellow, tinged 

 with brown in the apical half. 



Wings: hyaline, the costal margin somewhat darker. A large, dark spot above 

 the base of the Rs, a second smrounds Scj and a third at the tip of Sci, extending 

 down over cross-vein r. The whole apical portion of the wing from the stigma 

 down to the median veins is blackish. Dark clouds on the basal deflection of Cui 

 and cross-vein r-m; base of wing between R and Cu dark; veins brown; deflec- 

 tion of Ml + 2, very pale. Venation (see fig. 6): Sc long, Sci ending at a point 

 slightly anterior to the cross- vein r. Scj remote from the tip of Sci, about midway 

 between that point and the base of Rs. Rs long, feebly arcuated. Cross-vein r 

 far back from the tip of R i and just beyond the fork of R2 + j. R2 + s longer than the 

 basal deflection of Cui. Cell 1st M2 closed. Basal deflection of Cui anterior to 

 the fork of M. (Most of the pubescence of the wing disc has become detached due 

 to its being in alcohol with other specimens.) 



This species does not seem very closely related to any of the 

 described American forms. The three species with spots on bands 

 on the wings, innocens, O.S., fascipennis, Zett., and nuhilus, O.S. 

 are quite distinct in that the spotted and banded effect is brought 

 about by dark hairs, and not by the color of the membrane itself, 

 as in apicalis. It agrees with innocens in the essential features of 

 venation, closed cell 1st M2, divergent Anal veins, etc. 



Holotype: male, Burton, Ga. (May 20, 1911); Coll. J. C. 

 Bradley. 



Furcomyia monticola sp. no v. 



Male and female. Light yellow and brown; L. male 6-6.5 mm.; female, 7.5-7.8 

 mm.; w. male, 6.5 mm.; female 7 mm. 



Rostrum brownish-yellow; palpi brown, the first segment lighter colored. 

 Front and vertex, brown. Antennae: first segment, cylindrical, light yellow, with 

 a few scattered black hairs; remaining segments rounded-oval, almost monili- 

 form, brown. 



Thorax: Dorsum light yellow, marked with brown. Pronotum, very light 

 brown medially. Mesonotum: a straight band of brown beginning near the ce- 

 phalic margin of the praescutum, running backward and expanding out over the 

 caudal portion of the sclerite, in the middle ending just before the V-shaped suture 

 on the sides running to the suture and meeting the mark on the scutum; scutum 

 with two lunate brown maiks on each side of the yellow median line; scutellum 

 largely brown; postnotum brown, yellow on the cephalic margin. Metanotum 

 brown. Pleurae clear light yellow, immarked. Halteres pale, knob slightly 

 darker. Legs light yellow throughout, with numerous black hairs. 



Abdomen: dorsum yellowish-brown, the joints of the sclerites darker. Ven- 

 tral surface light yellow; genitalia brownish-yellow. Genitalia of male. (See figs.
