288 



were collected by Lieiiteuant Carpenter ou the foot-hills of Colorado iu 

 •September, 



This is quite variable in size, depth of colors, and in the number and 

 size of the bald white spots which occur ou the scutellum and hemelytra. 

 I am unable to decide which of the two names should have preference ; 

 both were published in the same year ; but, perhaps, the one was issued 

 a few days or weeks earlier than the other. 



2. G. congrua. Xew sp. 



Broadly oval, bright grass-green ; the upper surface and margins of 

 the pleurae finely and deeply punctate between slender transverse 

 rugfe. Head having the surface impressed each side of the tylus 5 the 

 lateral lobes a little longer than the tylus ; exterior margins acute, ele- 

 vated, more deeply sinuate than in G. Sayi. Antennae green, but with 

 the apical, the fourth, and the third, almost to its base blackish, and 

 these joints particularly granulose and setose 5 the second joint twice as 

 long as the third, the third much the shortest. Kostrum reaching to 

 the posterior cox?e, green ; the middle line and apical joint black ; basal 

 joint a little shorter than the head 5 the second longer, reaching to the 

 middle coxce ; the third and fourth subequal, but much shorter. Prono- 

 tum very short and broad ; the lateral margins very distinctly and evenly 

 reflexed, and continued around the broadly-rounded humeral angles, 

 the margin inferiorly appearing broadly tabulate and smooth. Pleurne 

 coarsely punctate, but more finely so on the elevated areas 5 the anterior 

 submargin transversely linearly carinated from the anterior angle to the 

 sternal boundary. Prosternum broadly, deeply scooped out, triangular 

 behind ; mesosternum slenderly carinate ; the metasternum produced 

 backward triangularly, and a little scooped out before the tip. Legs 

 green, the tarsi slightly rufous. Scutellum slenderly margined and more 

 broadly tipped with white. Corium more minutely rugulose, finely punc- 

 tate, the punctures grading finer posteriorly ; embolium smooth, having, 

 a few remote and obsolete punctures, and, together with the adjoining 

 margin, white. Membrane soiled white, having feleven longitudinal 

 nervures. Wings white, with the coarse costal nervure piceous. Tergum 

 black as far as to the penultimate segment, very minutely and closely 

 punctured and rugulose. Venter smooth, remotely, obsoletely punctured, 

 but almost destitute of punctures along the middle. 



In one specimen, the lateral margin of the pronotum is white, more 

 broadly so beneath, and the edge of the venter is deep orange. The in- 

 ferior genital segment is hairy and scooped out in the form of a crescent. 



Length, 9 to 12 millimeters. Width of pronotum, 5^ to 6^ millimeters. 



Inhabits Colorado. Collected by Lieutenant Carpenter on the foot- 

 hills of Colorado in September. 



3. G. ligata. 



Pentaioma ligata, Say, Heteropt. New HaiDiony, 5, No. 6. 

 Cimex rufocinctus, H.-Schf., Wanz. Ins. iv, 94, tig. 436. 

 Peniatoma marginalis, Walk., Brit. Mus. Catal. of Hemipt. ii, 238. 



Inhabits California, Mexico, Texas, New Mexico, Arizona, &c. 



Varies greatly in size ; the red color of the margin of the pronotum 

 and abdomen and the tip of the venter is sometimes substituted by 

 X)ale green or whitish. 



I do not think this subgenus can stand. The species composing it are 

 congeneric with Fentatoma junij)eri^ Linn., and must be associated with 

 it. If that species is really the type of Fentatoma^ Oliv., then all these 

 species must be i^laced therein.
