NO. 1977. MONOGRAPH OF THE SIONIPHORIN^—GIRAULT. 227 



the fore wing is also clear directly beneath the submarginal vein for 

 nearly its whole length. 



Belongs to the nigra group and that section of it containing those 

 species bearing marginal cilia at the apex of the fore wing which are 

 subequal to or longer than a third of the wing's greatest width, hence 

 allied with maxima Girault, pulchra Girault, noacki, Ashmead, and 

 nigrella Girault. However, resembling australiensis Ashmead and 

 at first mistaken for that species; the transverse clear band is some- 

 what farther distad (on the costal margin half or more of it extending 

 beyond the apex of the stigmal vein), more uniform and not coming 

 to a point at the stigmal vein; the longer marginal cilia of the fore 

 wing in australica, the narrower fore wings, the pallid legs and other 

 characters easily distinguish the two species. Of the four species 

 with which it is allied, it resembles, perhaps, ^^wZcAra more than the 

 others because of its moderately narrow fore wings, but the discal 

 bristle is absent and the oblique hair line-like crease but slightly indi- 

 cated; the legs are much lighter in color. The species need hardly 

 be confused with any other species of the genus, even its closest allies. 



Fore wings with the marginal cilia moderately long, those at apex 

 only about slightly over a third of the greatest width and slightly 

 longer than the apical marginal cilia of the posterior wings; stigmal 

 vein forming a regular concave curve with the inner edge of the 

 marginal vein at its apex, but the curve is not as deep as usual. Pos- 

 terior wings moderately broad, subequal in greatest width to their 

 longest marginal cilia or slightly more or less than subequal. Antennal 

 club long and moderately stout, spindle shaped, slightly over four 

 times longer than its greatest width which is near its middle, with 

 no regularly grouped nor prominent longitudinal sulci.
