TYPHLOCYBA ATHENE, new species 



Male. — Pale yellowish, the teomiiia with a greenish cast, apical cells 

 hyaline, underparts stramineous. Hj^popygium : Upper postei-ior 

 angle of 9th segment produced as a stout, somewhat decurved tooth, 

 the lower angle as a prominent, recurred, conical tooth, which is 

 heavily pigmented, posterior margin of segment between the 

 processes, convex (fig. 63). Outer clasper unusually long and slen- 

 der, tapered gradually on the basal three-fourths, then upcurved, 

 and abruptly narrowed, the apical fourth quite slender, distinctly 

 outcurved, somewhat spatulate apically, and pigmented. Inner 

 clasper hairy at base, slender, outcurved, the apex upwardly, and 

 somewhat anteriorly curved, aciculate. Aedeagus thrice as long as 

 connective, the central shaft rather stout, bifid apically into long, 

 blender, divergent aciculate processes; at about the middle of wliole 

 aedeagus two lateral arms arise from the central shaft, their taj)er- 

 ing pointed extremities about the same length as the apical processes 

 of the central shaft and paralleling them so closely as to con<;eal 

 tliem from the side (figs. 64r-65).

 heavily pigmented, (and visible from below between the outer 

 claspers) ; outer claspers rather slender and gradually tapered ; 

 inner of the simply curved and acmninate type; aedeagus with three 

 slender upcurved branches from base, the lateral ones nearly as long

 curved acuminate process (fig. GG).
