LIBURNIA (?) INCERTA, n. sp. 



Van Duzee, Bui. Bv:f. Soc. Nat. Sci., V, p. 192, 1894. 



Allied to L. Bohemani of Europe. Form and color of lutulenta nearly. 

 Short and stout; frontal carina forked opposite the lower angle of the eyes. 

 Length: Male 2, female 3 m. m- 



Male: Dark testaceous brown; front obscurely rufo-piceous, tergum 

 darker brown, the middle of the segments at base yellowish; pectoral pieces 

 and legs soiled yellow. Aperture of the pygofers broad below, the stiles 

 accummate, widely divergent and curved at apex, lower edge of the anal 

 tube forming a pair of acute incurved teeth which are approximate and 

 gibbous at base. 



Female larger ; tawny or honey yellow, paler beneath ; tip of the rostrum 

 and oviduct black. 



New York. Described from a single pair taken from a meadow near 

 Buffalo on the 14th of June 1893. The forking of the frontal carina near 

 the midrlle of the face recalls genus Pissonotus and the male is colored 

 much as is that of P. brunneus but it is a much stouter little insect and the 

 carina; of the pronotum are curved behind the eyes. 



LIBURNIA GILLETTI, n. sp. 



Gillett and Baker, Hemip. of Colo., p. 6g, 1895. 

 Brachypterous female: Color pale straw yellow marked with black. 

 Carinse of the pronotum and scutellum whitish, sides of the scutellum 

 becoming almost a saffron yellow. Face excepting the carinae and margins 

 deep black; apical fova and a dot near the outer posterior angle of each 

 basal fova on the vertex, the anterior angles of the pronotum exterior to 

 the lateral carina; and a small dot near the hind margin of the scutellum 

 just withm the lateral carina; black. Abdomen black, outer margin and a 

 dorsal line on the tergum, connexivum and pygofers pale yellowish ; slender 

 hind edge of the ventral segments and the stiles whitish. Legs and mar- 

 gins of the coxa; and pleural pieces pale, the femora and exterior edge of 

 the tibia; lineated with black ; anterior, intermediate and tips of the poste- 

 rior tibiae brown. Antennae yellowish brown with a black annulus on the 

 base of each joint. Elytra oblong, rounded at apex and exceeding the 

 abdomen, obscurely yellowish, subhyaline marginal nervures strong, yel- 

 lowish, discal distinct, concolorous. Oviduct and anal stile black. In many 

 examples there is a blackish dot on the disc of the pronotum either side of 

 the median carina and the pronotum may be minutely dusted with dusky, 

 or there may be a daricer longitudinal cloud on either side of the median 

 carina, or the disc of both may be black with the carina; pale and the lateral 

 margins yellowisli or even fulvous. The macropterous females in the 

 examples before me have the venter pale with a black discal cloud more or 

 less extended : the sides minutely dotted with brown and bearing a row of 

 black points, one on each segment, and the elytra are quite strongly clouded 

 with smoky toward their tips.
