margin of the segment, but distinct from it; not angulate externally; 

 epipleura of the elytra concave. 



C. saiiguinea, (Linn.) Cent. Ins., n. 11 ; munda, Say, Bost. J. i., 202, 1.— 

 Black, alutaceous, finely punctulate, thorax with the front, sides and hind an- 

 gles bordered with white, the front margin gives off three white branches, the 

 lateral ones sometimes reaching the base; elytra bright red, spotless. L.

% , head white in front; prosternum and meso-epimera white. 9> bead 

 with two white spots, body black. 



North and South America, abundant. 



The color of the legs, on which Mulsant has laid some stress is en- 

 tirely inconstant, and so is the presence of the medial tooth on the 

 thoracic border. 



C. OClllata, (Fabr.) Ent. Syst. i., p. 287, 98; binotata %, Muls, Trim., p. 322, 

 19. — Black, alutaceous, very obsoletely and finely punctulate; abdomen red, 

 epimera white; elytra each with an irregular red discoidal spot before the 

 middle, thorax with the sides bordered with white. L. -IS — -20 inch. 



% , head white in front. 



Var. abdominalis, Say. — Entirely pale ochreous, thorax with seven black 

 dots, five discoidal (forming an M-like mark), two lateral; elytra each with 

 eight black dots; four basal, three medial, one sub-marginal before the apex. 



This form often has a large black triangular mark in the posterior 

 half of the elytra.

 c, 56, 6. — Ovate, black, tarsi rufescent; head with two yellow frontal spots; 

 thorax yellowish-white with an M-like discoidal mark, and a lateral dot black 

 (or black with the front, sides and basal bilobed spot yellowish) ; obsoletely 

 punctulate; elytra clearly punctate, with a narrow medial and sub-apical 

 fascia, both abbreviated, black, margin with paler, and consisting of three and 

 two spots respectively; either or both (barda, Lee.) may be wanting, or two 

 disconnected spots may be left (ophthalmica). L. -18 inch.

A. Mpunctata, (Linn.) Syst. Nat., p. 364, 2; Muls. Sec, p. 61, 3.— Very 

 closely allied to the preceding by its coloration; but apparently not so vari- 

 able as in Europe; all the North American specimens are referable to the 

 typical form in which the elytra have each a tolerably large rounded discoidal 

 spot; it is larger than A.frigida, and the metacoxal line is exactly semicircular.
