Notes. — This we may call the typical species of the group, 
having the face yellow, rarely gray, and the veins of the wings 
also yellow. The abdominal design is very pronounced when 
the median stripe and the apical margins are gray instead of 
yellow, and the dark bands very shining. 
Notiphila atripes new species 
Allied to scalaris but hardly synonymous. It may be distin- 
guished by the elongated abdomen of the male and the black tarsi. 
Description of Male . — Similar to scafam. Black; halteres yellow. Frontal 
vittae black, distinct. Ai’ista with eight hairs. Thorax immaculate or meso- 
pleura slightly stained. Abdominal markings subopaque, broad, leaving nar- 
row median stripe and apical margins of segments gray; segment five entirely 
shining. Abdomen unusually narrowed and elongate. Length. — 3 to 5 mm.
