424 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



the black Hues of the venter are replaced by a broad continuous dark 

 stripe, running- the whole distance from the base to the tip. A marked 

 feature in the structure of the female is the large size of the last ventral 

 segment, which is broadly and deeply emarginated to admit the ovipos- 

 itor. Each lobe of this is triangular, with the apex truncated, and on 

 the tergal aspect the sides are very high, giving the segment the ap- 

 pearance of being hollowed out. 



■ Specimens from the mountains of Georgia and IS'orth Carolina are 

 sometimes very pale, with only a trace of rose-color in the cuneus, and 

 with but faint indications of the brown markings of the upper and lower 

 surfaces and bands of tbe thighs. 



Pamergcohis, new genus. 



Contour of the longer forms of AnthocoHs, but with the prouofcuin 

 and head closely imitating Ozophora and Ligyrocoris of the family Ly- 

 gceidie. Head horizon<"al, long conical, constricted behind the eyes, 

 compressed and tapering before the eyes; the eyes large, suborbicular, 

 prominent, almost as wide as the vertical thickness of the head; the ver- 

 tex convex between them, the carina connecting the base of the eyes ob- 

 solete ; tylus oblique, a little arcuated, prominent, occupying the whole 

 width of the tip of the head ; superior cheeks flat, ligulate, running par- 

 allel to the tylus behind it, and almost reaching to its tip ; the inferior 

 cheeks very small, sunken, placed obliquely behind the end of the supe- 

 rior ones. Antennae longer than the body with the hemelytra; the two 

 first joints stout, the basal one a little longer than from the eye to the 

 tip of the tylus, tapering at base ; the second cylindrical, a very little 

 shorter than the, corium and cuneus together ; third and fourth much 

 more slender, filiform, each longer than the basal, the fourth a little 

 longer than the third. Eostrum long and very slender, reaching to be- 

 hind the posterior coxae; basal joint a little longer than throat, a little 

 stouter than the second; second joint longer than the basal; third still 

 longer; fourth a little longer than the basal one. Pronotum campanu- 

 late, wide at base, narrow anteriorly, contracted in front, and with a 

 narrow collum on the anterior margin ; lateral margins sinuately cari- 

 nate; anterior lobe convex, the callosities separated by a short, longitu- 

 dinal grove ; posterior lobe slanting toward the transverse impressed 

 line ; the posterior margin is concavely sinuated, and the postero-lateral 

 angles produced, long and narrow. Prosternum a little depressed, the 

 sides carinately elevated, converging to an acute angle between the an- 

 terior coxae. Scutellum longer than wide, acute at tip, at base trans- 

 versely elevated, and behind this there is a transverse impressed line. 

 The sides are deeply sinuated and the edge slenderly carinate. Coxae 

 long, stout, compressed, the anterior ones longest and stoutest ; femora 

 compressed, slenderly channeled on the inner and outer faces, poste- 

 rior pair longest; the tibiae very slender ; tarsi long, the basal joint 

 longest, the intermediate one very short, the apical one shorter than the
