398 GEOLOGICAL SURVEY OF THE TEEEITOEIES. 



at tlie ends of the incisures ; venter yellowish, the punctures closer on 

 the sides, and with about three series of obsolete patches of blackish 

 punctures each side; the lateral edge smooth, orange, with a small, 

 double black spot at the incisures ; sometimes with the margin of the 

 anal segment black. 



Length, 8J to 10 millimeters ; width across the humeri, 5 to 6 milli- 

 meters. 



It inhabits Kansas, Colorado, and California. The general appear- 

 ance is somewhat that of R. sphacelatus^ Fab., of Europe; but it may be 

 known from it at a glance by the lateral margins of the pronotum, 

 which are not sinuated, but bowed. The lateral lobes fail to meet an- 

 teriorly in one specimen, making the front of the head appear cleft.

C. lynx, Fab., (Syst. Ehyng., p. 168, No. 68.)— From Southern Mon- 

 tana, but attains to colossal proportions in California. After close com- 

 parison of a series of specimens of very various sizes and colors, with 

 several individuals from Europe, and with the figures and descriptions 

 in the several authorities, I fail to find permanent characters to separate 

 them. Specimens vary in colors from pale green or yellowish to rosy 

 red; either have or do not have black spots on theconnexivum, and the 

 size ranges from 8 to 11 millimeters in length, with corresponding 

 width. 



Pentatoma^ Latr., (Fieber.) 



1. P. granulosa. Kew species. — ^General appearance oiF. juniper i, Linn. 

 Bright grass-gxeen, or pale sap-green, paler beneaAi, deeply, confluently, 

 rather finely imnctured, transversely, minutely wrinkled on the head, pro- 

 notum, and scutellum ; the surface of the latter, the hemelytra, and some- 

 times the pronotum, with numerous sphacelated, smooth, whitisb points ; 

 the lateral margins of pronotum, the costal margin of corium to beyond 

 the middle, and the apex of the scutellum white, rarely yellow. Eugulte 

 of the entire under surface whitish. Head narrowed toward the tip ; the 

 tip of the lateral lobes almost acute, a little recurved, slightly longer 

 than the tylus ; the occiput bald, almost impunctured. Autennai black, 

 stout; the tooth at base long and slender; basal joint green, very stout, 

 hardly more than one-half as long as the second ; the second longest ; 

 third a little more than two-thirds as long as the second ; fourth and 

 fifth subequal, somewhat longer than the third. Eostrum i:)ale green, 

 reaching between the posterior coxae ; the apical half of the end joint 

 black or i)iceous ; the labrum sometimes blackish. Lateral margin of 

 pronotum a little sinuated, the edge distinctly elevated, the sub-margin 

 depressed, and the surface broadly impressed at the outer end of the 

 callosities. Callosities defined by sinuated, grooved, smooth lines, 

 which are bifurcated at the outer extremity. Embolium whitish, hav- 

 ing two or three irregular series of obsolete, small i:)unctures ; membrane 

 white or only very faintly brownish. Femora obsoletely wrinkled, the 

 tips of tarsal joints infuscated, and the tips of nails piceous. Tergum 

 black, excepting the penultimate and anal segments ; the connexivum 

 green. Base of scutellum sometimes with small, white spots. 



Length, 11-13 millimeters ; width across the humeri, 0-8 millimeters. 



The specimens from this survey were found in Montana, and near 

 Ogden, Utah. It seems to be widely spread in the AYestern Territories, 

 and extends as far as California. Two specimens exhibit the third and 

 fourth joints of the antennae green at base, the former verj' broadly so.
