12. Intermediate praescutal stripes lacking or ill-defined, the laterals enclosing 



a pale median area; antennae chiefly dark brown; wings narrow, with 

 a clear-cut dark brown pattern, the series of spots in cell R small and 



well-defined; size small (w., 5, about 9.5 mm.) faliax 



Intermediate praescutal stripes well-marked, at least on posterior half ; 

 basal antennal segments chiefly yellow ; wings broader, with the pattern 

 paler brown, more diffuse ; spots in cell R larger, often poorly delimited, 

 more or less confluent; size larger (w., $, about 11 mm.) solitaria 



13. Femora brown, the tips conspicuously yellow ; wings with three large 



circular brown costal areas, located at origin of Rs, fork of Sc and on 



R„ maculicosta 



Femora yellow, with the apices dark brown (color unknown in sociabilis) ; 

 wing-pattern not as described, if n-itli three costal darkenings {trisiigma) , 

 these small and scarcely evident 14 



14. Wings witli conspicuous brown clouds and seams 15 



Wings immaculate or nearly so, at most with three or four small brown 



costal dots 17 



15. Large species (w., 15 mm. or more); apex of wing very obtuse; all cells 



beautifully clouded and marbled medially with gray and brown parietina 



Smaller flies (w., 12 mm. or less) ; apex of wing norinal ; wing-markings 

 beyond cord confined to vicinity of veins or lacking; the most evident 

 darken in.gs appear as a seam along cord and (in iiidigciia) as a broken 

 crossband before cord 16

transverse cloud before cord of wing baclia 



Abdominal tergites pale, the posterior borders broadly brownish black ; a 

 transverse broken crossband before cord of wing indigena 



17. Wings with three small brown dots along costal border: head entirely 



dark; antennae pale, darkened towards tips tristignna 



Wings yellowish, without markings ; head yellow, except on front ; antennae
