Ninth segment with a patch of bristles near articulation of outer 

 claspers, the latter with several equidistant long setae within; 

 posterior margin of segment and anal tube also with long slender 

 hairs, the apex of latter with a few bristles also. Outer and inner 

 claspers shaped as in T. fomaria (figs. 59-60). Aedeagus measured 

 along curve only about ly.^ times as long as connective, greatly 

 dilated subapically, the tip with four lanceolate appendages of 

 which the outer (morphologically inferior) pair are about one-fourth 

 longer, stouter, and more curved than the inner (figs. 31-32). 



Female. — Coloration as in male; eighth sternite moderately 

 emarginate laterally and quite pointed medially as in T . ariadne 

 (fig. 104).

TYPHLOCYBA XANTHIPPE, new species 



Male and female. — Agree with T. lethierryi as described in this 

 paper, except that the posterior appendages of the aedeagus are un- 

 branched, the anterior simply forked (fig. 34), and the eighth 

 sternite of female almost evenly convex. 



Length: 3.5-3.75 mm. 



Holotype. — Male, allotype, and paratypes of both sexes New York, 

 N. Y., June 22, 1924; paratypes and several teneral specimens; 

 Boston, Mass., June 23, 1924, E. D. Ball (Ball). 



A specimen from Lille, France, seems to be this species which

TYPHLOCYBA ARIADNE, new species 



Male.—V2X^ yellowish above, apical cells more hyaline, underparts 

 stramineous. Hypopygium : Upper angle of 9th segment produced 

 as a strong inwardly projecting tooth, below which the hind mar- 

 gin of the segment is emarginate, the side below this forming a 

 prominent obtuse lobe (fig. 35). Outer claspers gradually nar-
