parts stramineous. Hypopygi'um : Upper posterior angle of ninth 

 segment rounded, the lower produced as a short blunt tooth, the 

 apex of which as well as that of the outer clasper is heavily pig- 

 mented ; outer clasper narrowed from base, a little bowed outwardly 

 at two-thirds of its length, then narrowed and again slightly turned 

 outward at the apex which is broadly rounded; inner claspers 

 approximate medially, in general curved outwardly the apical fourths 

 rather abruptly so ; aedeagus thrice as long as connective, the slender 

 upwardly directed shaft bifid on the apical third into processes 

 which are lanceolately expanded apically (figs. 45-46). 



Length 3-3.5 mm. 



Holotype and paratype. — Males, Hampshire County, Mass., June, 

 1922, Philip A. Readio (Kans. Univ.) ; paratype male, Urbana, 111., 

 J'une 4, 1916 (111. State Nat. Hist. Survey). 



TYPHLOCYBA NIOBE, new species 



Male. — Head and thorax pale greenish yellow, tegmina to cross- 

 veins deeper yellow, apical cells hyaline; underparts stramineous. 

 Hypopygium: Upper posterior angle of ninth segment rounded, 

 lower produced downwardly in a short, blunt, black-tipped tooth. 

 Outer and inner claspers as in T. persephone. Aedeagus more than 

 twice as long as connective, bifid almost from base, the rami up- 

 wardly directed and parallel for three-fourths of their length, then 

 diverging outwardly and curving a little posteriorly, apices acute 

 (fig. 47). 



Female. — Paler than male; eighth sternite rather pronouncedly 

 emarginate laterally and pointed medially. 



Length 3.25-3.75 mm. 



Holotype.— MqXq, Racine, Wis., July 30, 1916, J. G. Sanders 

 (Ball) ; allotype, and paratypes, Iowa, No. 2803 (State Coll. Iowa) ; 

 paratypes of both sexes, Ames, Iowa, J'une 23, on hard maple, E. D. 

 Ball (Ball). 



Except for paler coloration this species agrees with the descrip- 

 tion of Empioa aureotecta Sanders and De Long^^. However, only 

 females of that form are loiown as yet, so the question of its exact 

 identity can be solved only by further collection and study.
