366 TEETIARY INSECTS OF NORTH AMERICA. 



Head uniformly dark, the sides of the frontal prominence full ; basal joint 

 of antennae barely shorter than the head, rather slender, a little thickened 

 apically ; second joint about two and a quarter times longer than the basal 

 joint, scarcely incrassated apically, the slender succeeding joints together 

 about as long as the second. Thorax more than twice as broad at base as 

 at apex, the apex einarginate, the base regularly arcuate, the tapering sides 

 distinctly though not strongly convex, the whole blackish infumate, and 

 smooth, in no way punctate, which is exceptional in Poecilocapsus. Scu- 

 tellum pale with a black edging. Hemelytra pale or light colored, with 

 the whole of the clavus black, a large, transverse, fuliginous cloud at the 

 outer extremity of the corium crossing the interior half of the hemelytra as 

 a narrow and vague stripe, and again enlarging, but more obscurely, at the 

 inner termination of the corium, and accompanied by a much smaller infus- 

 cation of the outer tip of the cuneus. 



Length of body, 6.75 mra ; breadth of thorax, 2 mm ; length of second 

 antennal joint, 1.7""". 



Named for one of the earliest scientific explorers of the Rocky Mount- 

 ains, Gen. John C. Fremont. 



Florissant. Five specimens, Nos. 8631, 9500, 12284, 13554, and of

2. PcECILOCAPSUS VETEKANDUS. 

 PI. 24, Fig. 9. 



Head but slightly produced in front of the eyes, dark ; basal joint of 

 antennae distinctly shorter than the head, a little incrassated apically ; sec- 

 ond twice as long as the first, its greater size distally than proximally 

 scarcely perceptible, the slender succeeding joints not fully preserved on 

 either specimen ; rostrum nearly reaching the hind coxse. Thorax fully 

 two and a half times broader at base than at apex, but otherwise shaped 

 exactly as in P. fremontii, the color blackish fuliginous, the surface punctate 

 with moderately distant minute black dots. Scutellum of the color of the 

 thorax. Hemelytra pallid throughout but the inner edge infuscated, and 

 slight infumated spots at the outer tip of the corium and cuneus. 



Length of -body, 5.8 mm ; breadth of thorax, 2.1"""; length of second 

 antennal joint, 1.45""". 



Florissant. Three specimens, Nos. 8648, 8849, 11785 and 12076.
