The Genus Scaphoideus. 



207 



Genitalia: Ultimate ventral segment 9, long, much pro- 

 duced, notched medially. 



Except for very different shape of genital segment this 

 might be considered an extreme melanotic variety of immistus, 

 but it is smaller, and the points noted seem so well marked 

 that until intermediate forms are found it must be considered 

 as distinct. 



Described from three specimens, all females, two of which 

 are from Texas (U. S. N. M.),and one from Hyattsville, Md., 

 collected by Mr. J. S. Hine, July 9, 1899. 



Scaphoideus obtusus n. sp. (Plate X, Fig. 14). 



A broad gray band from pronotum to anteapical cells. 

 Length, 9, to tip of elytra, 5 mm. 



Vertex depressed, obtuse, nearly twice as wide as long, 

 anterior margins curved, minutely carinate ; front narrow, 

 sutures converging but slightly till near the tip; clypeus 

 long, slightly enlarging to apex; lorse large, almost reaching 

 tip of clypeus and outer margin of cheek. Pronotum short, 

 lateral margins flaring, posterior margin evenly concave. 

 Elytra, appendix wide; post-nodal cell widening to apex and 

 sharply angular within, post-nodal vein slightly curved and 

 oblique ; outer claval vein hooked, remote from suture dis- 

 tally, with distinct cross veins at base to suture and to inner 

 vein. 



Color : Head and thorax nearly white or light yellow; vertex 

 cream white with a broad fuscous band between the eyes 

 enlarged at center to form a blunt point before and behind, 

 anterior margin showing a narrow black line; face black, the 

 disk less dense and the frontal arcs not entirely hidden. Pro- 

 notum fuscous or black with a milky median cross and pos- 

 terior border and some fulvous dots on anterior margin; scu- 

 tellum fuscous with the usual picture in white. Elytra white 

 except lines on the nervures, a basal spot next costa, the 

 anteapical cells and a terminal band, which are fuscous or 

 black. Abdomen below black with white margins. Below,
