2G8 GEO. II. iionx, m. n. 



This species niiiy also be considered an odd member of our fauna. 

 With our species only under consideration, I am compelled to associate 

 it with the Iciicoxrr/ia <i;rou]i. 



Occurs in southern ('alifornia, (San Diejj;o, Santa Isabel, A'allecita), 

 extending into the Peninsula. 



28. C. aii$;iiMtilS, Nowm. — Body beneath blnck, above entire)}' briglit 

 green as in .$C7-iccus. Head coarsely and deeply punotured except the epistotna 

 and middle of front, labruin truncate, antennae piccous, three basfil joints pale. 

 Thorax broader than long, broader at base than the apex, sides in front arcuate, 

 jiosterior third subparallel, disc moderately convex, evenly and very densely 

 punctate, basal impressions obsolete. Elytra scarcely broader than the thorax, 

 basal line angulate at humeri, strise fine and finely punctate, intervals flat, 

 moderatelv densely punctate and sparsely pubescent. Prosternuni margined 

 at tip, in front densely and coarsely punctate, e))isterna coarsely punctured. 

 Metasternal episterna very short, coarsely punctate. Abdomen coarsely jjunc- 

 tured at the sides, less coarsely at middle. Legs testaceous, tarsi darker. 

 Length .68 inch ; 17 mm. 



This species may be called an elontrate tomenfosiis in form, nor does 

 the resemblance cease here, the palpi being decidedly more dilated 

 than is usual in the present group. The anterior femora of the male 

 are rather suddenly narrowed at base. 



I have seen but two specimens S 9 , in the cabinet of Dr. Leeonte, 

 from Georgia. 



29. C. viUlltlM, Horn. — Agrees with augustus in sculpture, but is some- 

 what more elongate in form. Color beneath black, femora testaceous, tibiae 

 and tarsi black, above black with tinge of violet. The punctuation of the 

 thorax is a little less dense and that of the elytra rather more so. Antennae 

 black, except basal joint. Sculpture beneath as in augustus. Length 9 -^S 

 inch ; 17 ram. 



Two specimens only have been collected. The male is in the pos- 

 session of Dr. S. V. Summers, who collected the species in Missouri, 

 probably near St. Louis. 



30. C. sesfivus. Say. — Head and thorax green, slightly bronzed, elytra 

 black with bluish tinge. Head punctured as in augustus. Thorax nearly as 

 long as wide, base broader, sides with feeble sinuation posteriorly, disc coarsely 

 and densely punctured. Elytra striate, strife punctured, intervals finely, moder- 

 ately densely but not very distinctly punctulate. Prosternum and side pieces 

 nearly as in augustus. Length .64 — .68 inch; 16 — 17 mm. 



The anterior femora of the male are rather strongly subangulate 

 near the base. The thorax of the female is usually broader than that 

 of the male. 



The short metasternal episterna and subangulate male femora, will 

 readily distinguish this species from any of those with which it might 

 be confounded. 



Occurs principally in the Middle States region, and is not rare.
