20 1 



at center. Female ventral segment produced. Length : 9 , 

 6 mm. ; cT , 5.50 mm. to tip of elytra. 



Vertex rather acute, its length nearly equal to its width, 

 front with margins slightly sinuous, apex narrowing slightly 

 but abruptly to clypeus, clypeus narrow, widening abruptly 

 at apex ; Jprse narrower than in carinatus, touching margin 

 of cheek. Pronotum lunate, hind border slightly concave. 

 Elytra with claval veins strongly curved at tip, outer ante- 

 apical cell pointed, scarcely stylate, usually three recurved 

 veins arising from anterior part of anteapical cell. 



Color: Vertex yellowish, a broad fuscous band produced 

 at middle to nearly meet the broken marginal band and shad- 

 ing to light brown posteriorly; face dark above, lighter on 

 lower half ; the marginal band, and submarginal arc black, the 

 frontal semi-arcs fuscous and lower part of front lighter, the 

 cheeks under antennae and the apices of lorse fuscous, as also 

 the sutures; pronotum yellowish, with fuscous lateral 

 patches ; elytra whitish or hyaline, with fulvous areas on 

 discal and apical cells, and fuscous patches on clavus inner 

 discal cell, on nodal and apical veins and apical submargin. 



Genitalia : . 9 , last ventral segment long, produced at 

 middle, lateral angles rounded, pygofers reaching about to 

 tip of ovipositor, with a patch of black bristles near tip and 

 whitish bristles near middle; cT, valve short; plates broad 

 short, obliquely truncate, flat, lateral margin reflexed, less 

 than half the length of the large pygofers. 



Described from seven 9 s and two cTs of which three 

 females were taken at Ames, Iowa, August 3, 1896, August 7, 

 1897, and October 14, 1896. One at Sioux City, July 7, 1897. 

 Three 9 s and one cT Onaga Kans. (Crevecour) and one cf 

 from Kentucky (Garman). 



While this species approaches carinatus in size and general 

 appearance, it is quite distinct from it in the genitalia, and 

 also differs in the shape and markings on vertex and clavus. 



Scaphoideus carinatus n. sp. (Plate X, Fig. 10, 10 a, 10 b.) 



Large, light gray, with a heavy cross band on vertex; last 

 ventral segment of female, with a strong carina and project-
