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

 posteriorly, having a /^-shaped black mark betweeii 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. Antennse fulvous, densely beset with 

 blackish, erect, stiff 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 one ; apical 

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

 Eostrum reaching to the posterior coxse, 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 C0X8B. 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 leSwS 

 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, 1^-lf 

 millimeters. 



Inhabits the vicinity of Snake Eiver, Idaho. A poor specimen from 

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

 brought home by the survey.

1. G. rapidus, Say, (Heteropt., New Harmony, p. 20, No. 4 ;) Gapsus 

 multicolor, H. Schf., (Wanz. Ins. YIII, p. 19, Fig. 795.)— 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. G. Falmeri. New species. — Form similar to G. hipunctatus, Fab. 

 Bright, deep yellow, polished. Head smooth, impunctured, clothed 

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

 tion, and the cranium exhibiting traces of oblique strisB 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 corivex, 

 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
