Pachyopsis, new gen. 



Broad and robust; bead from above very short, bluntly rounded, in- 

 cluding the eyes a little wider than the pronotum, the vertex and front 

 confounded in a common convexity in both diameters; ocelli on a line 

 with the middle of the eyes, large, and placed remotely from each other; 

 front short and broad, prominently and abruptly raised above the level 

 of the cheeks and epistoma ; epistoma flat, almost as wide as long, short 

 and broad, the end truncated, and the sides a very little oblique, or 

 very feebly sinuated ; antennse short, the basal joint short, very thick, 

 rounded, the four following joints very short, narrow, tapering, the 

 apical one with a short, oblique bristle ; outer cheeks very broad, curv- 

 ing bluntly to concur with the tip of the epistoma ; inner cheeks wider, 

 a little longer than the epistoma, with the inner margin oblique and the 

 outer margin curving inferiorly and making an acute tip. Pronotum 

 transverse, of medium length; the posterior margin feebly concave, the 

 postero-lateral margins oblique, with the angles a little rounded. Hem- 

 elytra moderately long, not valvate, narrowing toward the tip, the tip 

 narrow and obliquely rounded ; inner margin straight, and the costal 

 margin broadly arcuated; nervures straight, the outer one acutely 

 forked near the base, and its two branches each forking on the last third 

 of the corium ; apical cells short, the middle one shortest, quadrangular; 

 the next outer one almost twice as long as the former ; the next inner 

 one widening posteriorly, and of the same length as the outer: the 

 outer marginal apical cell much longer than the other, and showing a 

 tendency to reticulation ; the inner marginal apical cell a little longer 

 than the one next outward, acute at tip. Anterior tibise with close, 

 long bristles ; posterior ones with long, stout spines. 



1. P. ketus, new sp. 



Clear yellowish-green ; contour someyvhut like Selenocephalus. Head 

 formed above of a narrow arc, its curve agreeing with the anterior curve 

 of the pronotum ; face bluntly convex ; the surface minutely sericeous 

 pubescent, very minutely rugulose; ocelli amber-yellow, large; anten- 

 nae pale yellow at base, a little dusky at tip ; eyes brown, triangular, 

 with the angles rounded. Pronotum transversely wrinkled, finely pu- 

 bescent ; the sides short, and with the edge slenderly recurved. Scutel- 

 lum broad and short, a little scabrous, and feebly punctate on the base 

 of disk ; minutely pubescent. Beneath paler ; legs yellowish-green, 

 the under side of tarsi and the pulvilli and nails slightly piceous. Heme- 

 lytra translucent, pale greenish, slightly blackish pubescent, coarsely 

 punctate in longitudinal series; nervures stout, those of the apical part 

 of the costal area a little reticulated ; costal nervule stout, recurved ; 

 the tip narrow, and obliquely rounded ; wings hyaline, with the ner- 

 vures scarcely discolored. 



Length to tip of hemelytra 7 millimeters. Width of pronotum 2^ mil- 

 limeters.
