Female. — Like the male in color, apex of ovipositor sheath black; 

 eighth sternite slightly emarginate laterally, very moderately pointed 

 medially. 



Length, 3.5 mm. 



Holotype. — Male and allotype female, Beltsville, Md., June 23, 

 1916, on Quescus alha^ taken in copula; paratype females same data; 

 paratype male, Odenton, Md., July 12, 1914, W. L. McAtee (Mc- 

 Atee). 



A male with same data as holotype, which almost entirely lacks 

 dusky markings, may be taken as the type of var. discincta, new 

 variety; it has a slight yellowish wash on tegmina, especially along 

 costa near crossveins. 



TYPHLOCYBA BERENICE, new species 



Male. — Pale yellowish overlaid with whitish; tegmina whitish 

 hyaline, small dusl^y spots in front of cross veins 2, 3, and 4, apical 

 cells with dusky clouding marginally; underparts stramineous. 

 Hypopygium : Upper posterior angle of ninth segment rounded pro- 

 tuberant (fig. 91) without inner teeth as in T, danae, posterior mar- 

 gin nearly vertical, lower angle rather squarish. Outer claspers of 

 ordinary form, the apices rounded ; inner claspers simply curved and 

 acute pointed. Aedeagus with short base, from which arise two 

 slender, outcurved arms which approach subapically where each 

 emits a slender very acute, inwardly and downwardly curved proc- 

 ess, apices of main branches of aedeagus, acute, slightly curved 

 posteriorly (figs. 88-89). 



Length, 3.5 mm.

Male. — Head and thorax whitish to stramineous, tegmina whitish 

 hyaline, with small dark sj^ots anterior to cross veins 2, 3, and 4, and 

 the apical cells with considerable dusky clouding, sometimes with 

 rather well defined elongate spot along the inner side of cell 1 ; 

 underparts stramineous, lower part of face yellowish. Hj^popygium : 

 Upper posterior angle well produced, rounded as seen from side 

 (fig. 93), incurved and pointed as seen from above or below; in the 

 latter view distinct serration of the margin is visible, as well as a 

 prominent incurved spine a little basad of apex (fig. 92) ; posterior 

 border of ninth segment nearly straight, receding, lower angle almost 

 eliminated. Apical third of outer clasper decidedly narrowed, 

 somewhat outcurved and slightly spatulate apically. Inner clasper
