 State Nat. Hist Survey) ; paratype males, Glencarlyn, Va., June 12,

In the holotype the third apical vein is not quite in line with the 

 third sector, hence this species has been keyed in Group 2 as well as

TYPHLOCYBA NICARETE, new species 



Male. — Vertex pale yellowish, thorax stramineous, tegmina whit- 

 ish hyaline, with small dusky spots anterior to cross veins 2, 3, and 

 4, apical cells slightly fumose; underparts stramineous. Hypopy- 

 gium: Posterior margin of ninth segment squarish as seen from side, 

 with an interior lengthwise, nearly median, chitinous supporting 

 strip, and another along margin, which unite to form a support 

 shaped like a falx of T. 'pojiuiria (fig. 59), which reaches the apex of 

 the rather pointed lower angle, upper angle rounded. Outer clasper 

 of ordinary form, narrowed on apical third; inner almost semi- 

 circularly curved, the pair tangent to each other in the middle 

 ventrally, the apices aciculate, directed outwards and barely extend- 

 ing beyond sides of outer claspers. Aedeagus short, stout, bifurcate 

 from middle, the arms, curved, stout, caliper-like, each abruptly con- 

 stricted at apex into a thornlike appendage which is directed 

 downwardly and inwardly (figs. 79-80). 



Female. — Colored like male, apex of ovipositor sheath black; 

 eighth sternite evenly convex posteriorly.
