NEW NORTH AMERICAN HOMOPTERA.— II. 



BY E. P. VAN DUZEE, BUFFALO, N. Y. 



Pediopsis tristis n. sp. 



Cinerous varied with fuscous ; apex of the front and basal angles of 

 the scutellum black ; pronotal rugae distinct. Length 45^-5 mm. 



Male. — Face with coarse rugose punctures, arranged in oblique lines 

 on the base of the front ; front black, cinereous at base and next the eyes, 

 with a broad, curved, transverse white band, including the ocelli ; clypeus, 

 lor^e and cheeks whitish, the former sometimes tinged with pale green. 

 Form of the pronotum about as in insignis ; cinereous clouded with fuscous 

 on the apex and along the posterior margin, with an elongated black spot 

 behind the mner angle of the eye ; rugte composed of profound elongated 

 punctures. Scutellum obliquely punctured on the disc ; cinereous, with a 

 brownish central band, and black triangular spots within the basal angles. 

 Elytra uniform greyish-brown, subhyaline ; nervures strong, evenly 

 margined with fuscous. Wings pale smoky hyaline, nervures brown ; 

 beneath whitish ] mtermediate pectoral pieces with a large black spot, a 

 smaller one just below the propleura, and on the latter a minute dot. 

 Venter dull yellowish, obscured next the connexivum and toward the 

 apex ; tergum more or less embrowned. Legs pale ; sides of the femora 

 and tibiae, and tips of the tarsi brown or blackish-brown. Plates ligulate, 

 narrowed and somewhat recurved toward the apex ; black or piceous, 

 fringed outwardly with long white hairs. Pygofers white, with a narrow 

 black apical margin, meeting on the ventral aspect almost to their tips, 

 leaving a slightly oblique orifice. 



Described from three males collected by Prof Herbert Osborn at 

 Fairfax, Iowa, June 22nd and 24th, 1889, to whom I am indebted for 

 specimens of this and a number of other interesting western forms. 



This sombre coloured species is most closely allied to my insignis, 

 from which it may be distinguished by its heavy margined elytral nervures, 

 the large black spot on the apex of the front, and by the rough appear- 

 ance of the pronotum, contrasting strongly with its peculiar velvety look 

 in insignis. Unfortunately there are no females at hand from which to 

 complete this specific diagnosis but there can be no risk in establishing 

 the species on one sex only. 



Pediopsis insignis is now known to me from Kansas, Iowa, Michigan,
