NORTH AMERICAN COLKOPTERA. 205 



C eiiprasceiis Lee, Proc. Acad. 1858, p. 85. — Brijiht brassy in color, 

 sparsely clothed with short cinereous pubescence. Thorax moderately coarsely 

 not closely punctate, sides arcuate, but never strongly so. Elytra not closely 

 punctate. Femora brassy, tibire rufescent, tarsi black. Length .16 — .20 inch.; 

 4 — 5 mm. 



In the origiual description the tibiae are said to be black, but this 

 has not been seen in any specimens before me. 

 Occurs in southern California, San Diego. 



C'. smaragdiilus Lee. Pacif. R. R. Rep. 1857, p. 67. — Variable in color 

 from cobalt-blue to green, femora metallic, tibife and tarsi black, surface very 

 sparsely clothed with short whitish hairs. Thorax not closely punctate and 

 much more finely than the elytra, sides of thorax moderately arcuate. Elytra 

 coarsely and moderately closely punctate. Length .16 — .20 inch. ; 4 — 5 mm. 



Some of the green varieties resemble cuprascens, but the thorax is 

 more finely punctured and the elytra and the legs always black. On 

 the other hand some of the smaller forms resemble varicolor, and 

 will be referred to under that species. 



California : Sacramento to Los Angeles. 



C varicolor Crotch, Trans. Am. Ent. Soc. 1874, p. 79. — Color variable from 

 green to blue or coppery, surface cinereo-pubescent, the pubescence more con- 

 spicuous and persistent than in the other two species. Thorax strongly arcuate 

 at the sides and near base rather abruptly narrowed, the surface moderately 

 coarsely and closely punctate. Elytra more coarsely, but less closely punctate 

 than the thorax. Femora metallic, rufescent at base, tibiae rufescent. tarsi brown. 

 Length .10 — .12 inch.; 2.5 — 3 mm. 



In this species the pubescence is always more conspicuous than in 

 either of the preceding. The surface is more coarsely and closely 

 punctate. The small specimens of smaragdulus which resemble this 

 may be known by the form of the thorax, with punctuation liner 

 than on the thorax. In the present species the legs are always more 

 largely rufescent than in either of the preceding. 



Occurs at Santa Barbara, Tejon and San Bernardino in California. 



GUAPHOFS Lee. 



The species of this genus were formerly placed as Heteraspis, from 

 which genus they differ in having a deep groove surrounding the eye 

 in part. In the " Catalogus Eumolpidarum," Lefevre makes Gra- 

 phops a synonym of Scelodonta, a view which seems not well founded, 

 from the fact that none of our s[)ecies have a tooth on the front 

 femora. In fact, Graphops seems to be intermediate between Scelo- 

 donta and Syrieta. 



The species have been well separated by Dr. LeConte in a table 



TR.iNS. AM. ENT. SOC. XIX. JULY, 1892.
