NO. 204:1. THE INSECT FAMILY DELPHACIDAE— CRAWFORD. 591 



Female genital segment longer and narrower than in dorsalis; 

 ovipositor sheath not foliaceous, cylindrical and extending almost 

 to tip of abdomen. 



Described from one female and four males from Alabama (Baker) , 

 labeled *S'. lautus Van Duzee. These are entirely distinct from the 

 type-specimen of this species. The characters most widely differing 

 from the other species are the genitalia of both sexes.

STENOCRANXJS CROCEUS Osbom and Ball. 



Plate 46, fig. M; plate 49, fig. O. 



Stenocranus croceus Osborn and Ball '96:233. 

 Kelisia crocea Van Duzee '97:233.— Osborn '97:235. 



Length of body, 3.4 mm.; width of vertex, 0.24; width of frons, 

 0.28; antenna, I, 0.06, II, 0.22. General color light yellow, with 

 some whitish areas; vertex and dorsum between lateral carinse 

 whitish, venter pale. Body rather large. 



Head moderately long, relativel}^ quite broad, distinctly narrower 

 than prothorax, rather strongly carinate; vertex broad, subrec- 

 tangular, produced only about a fourth of its length before eyes, dis- 

 tinctly longer than broad; frons long, narrowed between eyes, sides 

 subparallel below ocelli; antennae rather short, II three times as long 

 as I, or more. 



Thorax long, not broad; pronotum two-thirds as long as vertex, 

 one-third as long as scutellum, long behind eyes, rather strongly 

 carinate; calcar typical, rather large, finely dentate. Elytra long, 

 subhy aline, quite broad. 



Female ovipositor sheath cylindrical, not expanded. 



Kedescribed from three females, two from Kansas and the other 

 from Massachusetts. This species was placed in the genus Kelisia 

 by Van Duzee, but I can see no justification for such a disposition 

 of it, since it is manifestly more closely related to members of the 

 genus Stenocranus than to Kdisia, although the vertex is rather 

 broader than usual in the genus.
