ART. 18 JASSID GENUS TYPIILOCYBA McATEE 7 



Male. — General color above pale greenish-yellow, the costa glassy, 

 the membrane fumose hyaline; faint clouds between sectors anterior 

 to cross veins, first cross vein and ends of apical veins, dusky ; imder- 

 parts pale yellowish, sometimes with narrow transverse dark bands 

 across abdomen. Hypopygium : Outer claspers of the same shape and 

 with the same bristling as in uhni (see fig. 11). Inner clasper with 

 a distinct, slightly falcate tooth below at beginning of apical curva- 

 ture, apex acute. Aedeagus with a stout central shaft and two 

 longer, rather broad, and moderately pointed lateral appendages 

 from the base (figs. 16-17). 



Female. — Coloration as in male. Eighth sternite a little more 

 rounded medially and less emarginate laterally than in ulmi (see 

 fig. 105) ; bristling of ovipositor sheath the same. 



Length 3-3.5 mm. 



Distribution. — Has been recorded from many localities in Europe 

 from Sweden to Italy and westward; specimens from England and 

 France have been available for the present study and from them 

 the description here given has been drawn. The writer has been 

 unable to verify the reported occurrence of this species in America. 

 Van Duzee ® gives records for Quebec, Ontario, Maine, New Hamp- 

 shire, New York, Michigan, and Colorado. 



TYPHLOCYBA PISCATOR, new species 



Male. — Head and thorax pale yellowish, the tegmina whitish hya- 

 line, sometimes slightly washed with yellow ; faint clouds between 

 sectors anterior to cross veins, and distal ends of first cross vein and 

 apical veins, dusky (fig. 1) ; underparts pale yellow. H3^pop5'^gium : 

 Lower posterior angle of ninth segment well rounded off, the upper 

 rounded prominent; outer claspers distinctly shouldered; inner 

 clasper with a tooth below at the beginning of apical curvature, the 

 apex very acute. Aedeagus with the long slender central shaft bent 

 doAvnward (just the reverse of the prevailing type in the genus) the 

 apex aculeate; just basad of the apex are two pairs of slender, curved, 

 pointed appendages of which the inferior are longest. From the base 

 of the aedeagus arise two long sinuous pointed processes, three- 

 fourths as long as the aedeagus itself (fig. 21-22). 



Female. — Colored like male. Eighth sternite convex, slightly 

 emarginate both medially and laterally.
