beliiud tlian in that species. Head yellowish, pubescent, indented 

 posteriorly, having a /^-shaped black mark between the eyes, the tip of 

 tylus, a spot behind the eyes, a partial circle around the eyes, and a 

 few dots on the gense, black. Antennae fulvous, densely beset with 

 blackish, erect, stiii'pile; the basal joint very thick, a little longer than 

 the pronotum; second joint a little more slender, tapering toward the 

 tip, as long as the distance from the tip of head to the second ventral 

 segment; third joint slender, a little longer than the basal onej apical 

 joint still more slender, less than one half the length of the third. 

 Eostrum reaching to the posterior coxae, pale yellow; the apical joint 

 piceous, excepting only at base. Pronotum not much widened pos- 

 teriorly; yellowish, with a dark line each side, and black spot; the 

 lateral margins narrowly reflexed, faintly sinuated ; the surface having 

 three or four transverse, impressed lines, and behind the collum with 

 an obsolete, collar-like ridge. Pectus yellow, a pale-brown stripe on 

 the propleura, and a few brown marks on the middle and posterior areas 

 and coxae. Legs lost from the specimens. Scutellum yellow, with a 

 triangular black mark each side near the base. Hemelytra shorter 

 than the abdomen, yellow, with a long, large, dusky cloud on the disk ; 

 membrane whitish, with the nervule dusky. Tergum more or less 

 saturated with reddish or brown on the sides of the segments ; venter 

 yellow, pubescent, with pale-brown spots each side, which include an 

 impressed, short, black line on each of the segments, excepting the anal 

 one. 9 



Length to tip of venter, 8 millimeters ; width across the humeri, 1J-1| 

 millimeters. 



Inhabits the vicinity of Snake Eiver, Idaho. A j)oor specimen from 

 Dakota, in my own collection, has much shorter hemelytra than that 

 brought home by the survey.

1. C. rapidus, Say, (Heteropt., IS'ew Harmony, \). 20, No. 4 ;) Capsns 

 muUicolo7'j H. Schf., (Wanz. Ins. YIII, ]). 10, Fig. 705.) — Brought from 

 Colorado. The reddish variety extends as far west as San Francisco. 

 Western specimens exhibit much difference in colors and pattern of 

 marking; while in several parts of the Atlantic region a singularly 

 exact uniformity of color prevails. 



2. C. Palmeri. New species. — Form similar to G. hipunctatus, Fab. 

 Bright, deep yellow, j)olished. Head smooth, impunctured, clothed 

 with long, remote hairs, the vertex having a broad, rounded indenta- 

 tion, and the cranium exhibiting traces of oblique striaj each side, run- 

 ning from a central line; eyes brown, with the orbits more or less yel- 

 low ; the occiput, throat, tylus, antennae and rostrum black ; or with 

 the cranium and face black, excepting only the cheeks and a spot on 

 the middle. Antennae as long as from the tylus to the tip of cuneus; 

 the second joint as long as the pronotum and scutellum united, cylin- 

 drical, a very little more slender at base than tip ; the third and fourth 

 joints together about two-thirds the length of the second; the third a 

 little longer than the fourth, both slenderly tapering to the tip ; ros- 

 trum reaching to behind the posterior coxae; the second and fourth 

 joints longer than the basal one, subequal in length ; the third very 

 much shorter than the basal one. Pronotum moderately convex, 

 coarsely, obsoletely punctured, with remote, erect hairs; sides oblique, 

 straight ; the disk with two round black dots, or with an irregularly 

 subquadrate spot on the middle, or with a transverse spot in front
