Forster. 
Table of Species. 
(2) 1. Stigma oval, lanceolate, broad in the middle, 
attenuated towards the extremity, emit- 
ting the radial nervure just before the 
middle 1. florimela, Hal. 
(1) 2. Stigma linear, scarcely, or not at all, broader 
in the middle, attenuated towards the 
extremity, emitting the radial nervure not 
far from the base. 
(6) 3. Stigma not reaching beyond the middle of 
the radial areolet ; 2nd cubital areolet 
narrowed on the outer side. 
(5) 4. Abdomen after the 1st segment reddish or 
testaceous, the posterior segments cinc- 
tured more or less distinctly with dark 
bands 2. rufiventris, Nees, 
(4) 5. Abdomen black; segment 2 pitchy at the 
base 3. Isabella^ Hal. 
(3) 6. Stigma as long as f of the radial areolet, or 
longer, and in that case confounded with 
the metacarp ; 2nd cubital areolet hardly, 
or not at all, narrowed on the outer side. 
(8) 7- Second abscissa of the radial nervure not 
longer than the 1st intercubital nervnre ; 
2nd cubital areolet very short, not longer 
than broad ; radial areolet somewhat lan- 
ceolate, not reaching the tip of the wing. 4. Bictynna, Marsh. 
(7) 8. Second abscissa longer than the 1st inter- 
cubital nervure ; 2nd cubital areolet longer 
than broad; radial areolet cultriform, 
almost reaching the tip of the wing.

? . Black, shining. Head much wider than the thorax ; man- 
dibles red ; palpi pale. Antennae slender, twice as long as the 
body, 48-50-jointed, the two basal joints red, the 4th a little longer 
than the 3rd (which is not the case in the other species). Furrow 
of the mesopleurae rugose ; mesothoracic sutures hardly inchoate ; 
a short linear impression before the scutellum ; metathorax finely 
rugulose. Wings hyaline ; squamula red ; nervure and stigma
