3o8 MEMOIRS ON THE COLEOPTERA 



two small spots on the pronotum, several small elytral spots and 

 two maculae on the pygidium, cretaceous; the clypeus is rather 

 deeply sinuate and somewhat narrowed at apex, probably as in 



lesueuri. 



Group II. 

 Subgenus Erirhipidia nov. 



In general habitus the few species of this subgenus differ greatly, 

 not only from the preceding group, but from any other of the genus; 

 they are more abbreviated and subquadrate in outline and have 

 a peculiar system of coloration and vestiture. We have, so far as 

 discovered, two species and one subspecies as follows: 



Form short and stout, oblong-oval, the hind body parallel to very feebly 

 cuneiform, broadly and obtusely rounded at apex; upper surface 

 opaque, pale tawny-yellow, the pronotum irregularly variegated to 

 wholly black, excepting two small approximate pale spots at the 

 scutellum, closely clothed with stiff yellowish hairs of variable length, 

 wanting at base medially and along an entire median line, which is 

 tumid ; scutellum pale, with the median line basally and apically black, 

 to wholly dark excepting two subbasal pale spots, the elytra mottled 

 with small irregularly distributed dark spots, sometimes in part 

 sublinearly arranged along the feeble convex costae; pygidium with 

 the pubescence rather long and coarse but very irregularly dis- 

 tributed, the sculpture fine and dense, more opaque in the sub- 

 glabrous areas; under surface blackish, shining, the abdominal seg- 

 ments rufescent at apex, the pubescence of the sterna, abdominal 

 sides and femora long, dense, yellowish and conspicuous, the internal 

 fringe of the tibiae very long but regular and in a single series; head 

 rather shining, black, densely punctate and pubescent, the more 

 finely punctate clypeus with a central nodal point, from which the 

 hairs radiate, the reflexed apex broadly rounded, the median sinus 

 very small and obsolescent; prothorax a third wider than long, the 

 sides subangulate medially, becoming subparallel basally, the 

 punctures fine, irregularly distributed, dense laterally and apically, 

 elsewhere irregularly sparser; scutellum with a few punctures later- 

 ally toward base; elytra generally impunctate, excepting some ir- 

 regular incised lines at apex, but sometimes with indefinite rows of 

 small discal punctures; hind tarsi rather short but not thick; teeth 

 of the anterior tibiae acute but moderate, only a little higher than 

 wide and not at all curved, almost similar in the sexes. Length (cf 9 ) 

 10.8-15.3 mm.; width 6.3-9.0 mm. New York to Florida and west- 

 ward to Nebraska. Very common. [Scarabtzus indus Linn., 

 Cetonia marylandica Froh., barbata Say and brunnea G. & P.]. 



inda Linn. 



A Similar to inda but still stouter and more parallel, the opaque 

 upper surface entirely black, excepting a few small pallid spots on
