CETONIIN^ 291 



tawny-yellow, the sides of the pronotum narrowly and irregularly 

 tawny; head nearly as in the preceding, the medial ridge acuminate 

 apically, the clypeal horn short and subparabolic in the type; pro- 

 thorax more rounded at the sides than in the preceding, becoming 

 more oblique and straighter apically; elytra nearly similar, excepting 

 the much more evenly rounded and rather narrow apex; pygidium 

 more finely and closely strigilate throughout, with the green and tes- 

 taceous parts abruptly defined, the former lobed medially; minute 

 sparse hairs are visible throughout; under surface in part testaceous, 

 the abdomen polished green, pallid along the middle, the hind coxal 

 plates brilliantly cupreous, the femora testaceous; anterior tibiae 

 bidentate; hind tarsi fully as long as the tibiae. Length (cf) 15.0 



mm.; width 8.2 mm. North Carolina parvula n. sp, 



9 Outline more or less stout, feebly convex and rhombiform, the elytra 

 not serially punctulate; upper surface opaque, the pronotum obscure 

 green, with tawny side margins, the elytra always with tawny 

 margins and apex, but with the disk varying from solid obscure 

 green to tawny with merely an oblique nubilously green streak 

 from the middle of the base to the middle of the suture, these extremes 

 of coloration rather unusual; head shining, green, the clypeal horn 

 always notably small, parabolic to a truncate triangle; prothorax with 

 subevenly arcuate and converging sides from base to apex, sometimes 

 with a slender pallid streak on the basal lobe, always very nearly as 

 wide as the elytra, which are but slightly longer than wide, with the 

 sides distinctly converging from base to the rather broadly subtrun- 

 cate apex and straight, becoming more or less feebly arcuate pos- 

 teriorly; pygidium with green metallic basal, and testaceous apical, 

 part, the green moderately prolonged medially; transverse strigilatiort 

 rather loose as a rule, generally becoming short sparse transverse- 

 lines apically, the pubescence sparse, varying from minute to coarse,, 

 longer and distinct hairs; under surface extremely variable, almost 

 wholly metallic green to, in large part, pallid, the femora always pale; 

 anterior tibiae usually with three evident teeth in the female, the 

 uppermost generally but not always obsolete in the longer and more 

 slender tibia of the male; hind tarsi about as long as the tibiae (cf 1 ), 

 or more or less distinctly shorter (9). Length (26 d 71 , 21 9) 

 16.5-22.0 mm.; width 9.3-12.4 mm. New York to Virginia; also 

 Tennessee River and Louisiana (Baton Rouge). Very common and 

 variable in color; the specimens from the western regions are rather 

 larger and more broadly oblong-oval than those from the eastern 

 slopes of the Appalachian system. [Scarabaus nitidus Linn, and C. 



flagranticeps Voet.] nitida Linn. 



A Similar to nitida but larger, opaque green, similarly margined with 

 tawny yellow, the elytra each with a regular oblique tawny vitta 

 from within the humerus to the apex at the suture; pygidium and 

 under surface nearly similar, the hind tarsi however notably 

 stouter, more compressed and proportionally shorter; anterior 

 tibiae (9) equal in length to the tarsi, distinctly tridentate. 

 Length (9) 24.0 mm.; width 14.0 mm. Texas, .ornata n. subsp. 

 B Form more oblong-oval, the opaque green of the preceding species
