the deflection of R,,;; veins R, and 7; generally parallel to 
the margin; inner ends of cells R3, R;, and Ist J/, in align- 
ment; r—m gently arcuate; cell /, small, less than one-half 
its petiole; cell lst M, relatively small, the basal deflection 
of Cu, near three-fifths its length; arculus unbroken. 
Abdomen dark brown, the sternites a little paler ; hypo- 
pygium obscure yellow. Male hypopygium unusually large 
and complicated in structure for a member of this genus. 
Ninth tergite terminating in two slender straight rods that 
lie parallel to one another. Pleurites produced caudad 
into slender black rods that are expanded at their tips 
aud here weakly hairy; dorsad of these rods on either 
side arises a very long, pale, curved appendage, directed 
caudad, the tips mesad, the extreme apices blackened. 
Ninth sternite appearing as two subglobular setiferous 
lobes. Eighth sternite tapering to the apex, which bears a 
conspicuous comb of blackened teeth.
