the wing; wing tip suffused with brown; inner end of cell Ro, adjoining vein 

 i?2, pale, hyaline ; remainder of cell R^, most of R^ and outer end of Rr^, uniformly- 

 brown, without hyaline droplets as in most of the species ; veins rather indis- 

 tinctly seamed with darker color; stigma dark brown, uniform. Venation 

 (see Fig. /) : 7?,, very strongly arcuated, beyond the arcuation, Rg is shorter than 

 Mi+, between the cross-veins r-in and m ; fusion of M^ and Cu-^ extensive, longer 

 than 7?o. 



Abdomen : tergum brown, segments paler basally, rather darker apically ; 

 8th segment brownish-black ; hypopygium pale ; sternites not visible in the single 

 specimen before me.

This small species is conspicuously different from the nearest 

 related species in its wing and leg pattern. The lack of hyaline drop- 

 lets in the ends of the radial cells distinguishes it from similis, hrevi- 

 ventris and zvilliamsoni. The leg pattern is closest to pictipcs, but I 

 cannot believe the two species to be conspecific. Pictipcs is larger, 

 and the dark tibial band in only 3 mm. broad; Candida is our small- 

 est species and the tibial band is broad, narrowest on the hind legs 

 (6 mm.) and very wide on the fore legs (12 mm.).

 two basal segments yellow ; rostrum yellowish above, brown below ; palpi brown 

 at base and tip but yellow in the middle. Ground color of thorax brownish- 

 yellow; collare with a short double longitudinal stripe in the middle and a 

 lateral brown spot on each side ; mesonotum with a double brown intermediate 

 stripe and short, broad lateral stripes ; metanotum pale with three brown stripes ;

 genitals, small, yellowish. Halteres brownish, paler at bases. Femora brown- 

 ish, the tip yellowish-white for about 1.5 mm.; tibiae and tarsi yellowish-white
