(Fig. 29.) 



Male. — Beautifully variegated in color, black, brown, yellow, and 

 white, as follows: Upper occiput and front ochraceous, paler tow^ard 

 antennae; face, vibrissal angle of cheeks, lower occiput, mouth parts, 

 and antennae flavous, cheeks blackish; mesonotuni ochraceous before 

 suture, the sides between the brown humeri and root of wing white, 

 posterior two-thirds of notum dark castaneous, scutellum whitish, 

 metathorax black, pleurae entirely blackish brown; base of abdomen 

 yellowish, remainder black; coxae and posterior femora except knees 

 blackish, remainder of legs pale yellow; halteres yellow; wings with 

 two infumated cross-bands, one including apical fourth, the other 

 extending between the crossveins, base and preapical portions sub- 

 hyaline, costal veins yellow up to the apical cloud; arista black, 

 bristles and hairs nearly concolorous with the integument, the 

 reclinate front-orbitals and setae of front femora black. Arista long- 

 pubescent, buccal hairs small; front occupying less than one- third 

 the head, longer than wide, its orbits nearly parallel; prescutellars 

 relatively strong, only one lateral scutellar seta; front femora with 

 double row of flexor setae; the black hypopygial valves shaped like 

 an orange spoon; third vein ending at tip of wing, parallel with fourth ; 

 sections of costa 5.5 : 1.4 : 1, of fourth vein 1:1:3. Length 3 mm.

60. SOBAROCEPHALA FERRUGINEA Czerny. 



Sobarocephala ferruginea Czerny, Wien. ent. Ztg., vol. 22, p. 105 (1903). 



Ochraceous, bristles concolorous, sometimes scutellum and pos- 

 terior middle part of mesonotmn brownish; arista evidently plumose; 

 front tarsi brownish, front femora with flexor bristles; wings nearly 

 hyaline, with a faint apical clouding; 3.5 mm. 



Habitat. — Peru. A few specimens from Costa Rica secured from 

 Pablo Schild probably belong to this species. The hypopygium is 

 small and yellow, the middle portion of the abdomen brownish. 

 Possibly S. dorsata is the same species, since the relative intensity 

 of dark color in the scutellar region is of doubtful specific value. 



61. SOBAROCEPHALA FINNILAI Frey. 



Sobarocephala finnilai Frey, Ofvers. Vet. Soc, vol. 60, p. 32 (1919). 



Head, including antennae and mouthparts ochraceous, arista 

 plumose. Thorax ochraceous, with two broad black vittae which 

 are triangularly excised along outer side at suture, scutellimi and 

 metathorax black. Abdomen black except at base. Legs entirely 

 yellow. Wings cinereous, costal cell and base yellow, with three
