(the inner medial spot prolonged almost up to the scutellum), also a 

 large sub-apical spot generally reaching the suture, or black with an 

 internally abbreviated red fascia beyond the middle. 



B. — Mesosternum straiyhtly margined, thorax finely margined. 



a.—Meso- and meta-epimera conspicuously white, thorax white in front. 



C. trifasciata, Linn. S. "S., p. 365, 6. — Hemispherical, black, punctulate, 

 thorax at the anterior angles with a quadrate white spot ahove and below and 

 the anterior margin white; elytra orange, with three fasciae black, one sub- 

 basal, common, the other medial and sub-apical, abbreviated at both ends. % 

 head entirely white in front. L. *22 inch. 



Var. Juliana, Muls. Op. vii.. 135; barda, Lee. Pr. Acad. (1860), p. 286.— Elytra 

 with the basal band only left. 



Var. Eugenii, Muls. Mon., p. 95, 35. — Elytra with the basal band divided. 



Var. subversa Lee. Pr. Acad, vii., 19. — Elytra spotless. 



Lake Superior, Oregon, Siberia, Lapland. 



C. <lilli«*ilis. sp. n. — Very like C. trifasciata and similarly jjunctate ; the 

 head has two white spots in front and the thoracic' angles have a quadrate 

 white spot; the elytra have a scutellar spot, and each three others black; one 

 medial moderately rounded, one sub-apical transverse large, one small sub- 

 marginal, a little nearer the base than the medial one. L. - 22 inch. 



Utah. (Horn.) 



This may best be described as being C trifasciata with the thorax 

 not white in front, the basal band gone and the medial divided. 



C. 9-notata, Hbst. Kaf. v. 269, 8.— Very like C. trifasciata, but larger, alu- 

 taceous, very obsoletely punctulate: the elytrainarkings are typically one 

 common scutellar spot, one on the callus, one small near the margin (con- 

 nected with the preceding sometimes), one large discoidal, one sub-apical. L. 

 •26— -30 inch. 



Var. franciscana, Muls. Op. iii., p. 19. — Elytra spotless. 

 Atlantic Region, Mexico, Guatemala. 



b. — Meso-epimera white, meta-epimera sometimes whitish in the % . 

 * Elytra alutaceous, obsoletely punctulate. 



C. 5-notata, Kirby, Faun. B. A. vi., 230, 313. — Black, elytra orange, with 

 a sub-basal common fascia, a transverse medial spot near the suture and 

 another towards the apex near the margin. L. "28 — '30 inch. 



Var. transversalis, Muls. Trim., 117. — Basal band divided, or only the scu- 

 tellar spot left. 



Var. californica, Mann, B. M. xvi., 312. — Elytra entirely pale. 



Siberia, Hudson's Bay, Greenland, Kansas, Utah, California, Mexico. 



This may be known from the two following by the epipleura of the 

 thorax which have the anterior angle alone narrowly white, where, as 

 in C. monticola and C. prolongate/,, it is as broadly white as the spot 

 above.
