median line; scutellum acute, with a very few small punctures; elytra 

 slightly cuneiform, feebly convex, obtuse at apex, the two costules 

 feeble; punctures shallow, lineiform or arcuate; pygidium with inter- 

 lacing concentric incised lines, umbonate at apical fourth or fifth (d"), 

 or feebly prominent nearer the apex ( 9 ) ; tarsi rather short, not very 

 thick; anterior tibial teeth long in both sexes; male much the smaller 

 and more slender. Length (c? 9 ) 12.0-14.7 mm. ; width 6.2-8 4 mm. 

 New York to Maryland. [ Cetonia herbacea Oliv., antennata G. & P. 

 and pubera Gyll.] herbacea Oliv. 



Body wholly without tomentose spots on any part of the surface, dark 

 olive green and opaque above, without distinct pubescence, except 

 the minute hairs toward the sides of the pronotum, the surface there 

 narrowly polished and metallic green; on the pygidium the coarse 

 pale hairs are sparse and short but distinct; under surface and legs 

 shining, brownish, with thin green lustre and rather long hairs, the 

 latter sparse on the abdomen except at the sides; tarsi rather slender, 

 black, the posterior as long as the tibiae in the male; head shining 

 as usual, strongly punctured, formed as in fulgida, glabrous, with 

 moderate hairs on the front; prothorax slightly wider than long, the 

 sides feebly arcuate, rather more so medially as usual; punctures very 

 minute and remote, becoming rather large, close and lineiform toward 

 the sides; scutellum dull and punctureless; elytra feebly cuneiform, 

 with obtusely rounded apex, the two costules broad and feebly con- 

 vex, each clearly defined by a row of small, obliquely arcuate punc- 

 tures at each side, with a similar double row nearer the sides, the 

 flanks transversely rugose; surface with extremely few small red 

 maculations; pygidium testaceous, with thin green lustre, the inter- 

 lacing incised lines circularly arranged as usual about the umbo, 

 which is very obtuse at apical third; sterna with long waving incised 

 lines. Length (c?) 14.5 mm.; width 8.0 mm. Mexico. [ Cetonia 

 submaculosa G. & P.] *submaculosa G. & P. 



7 Upper surface shining throughout, the pronotum with tomentose 

 margin within the beading; clypeus more strongly reflexed and sinuate 

 at apex in the male than in the female, the lobes obtusely dentiform 

 in the former as a rule 8 



Upper surface at least in part opaque; pronotum not tomentose at the 

 sides 10 



8 Sutural angles of the elytra obtuse, not denticulate in either sex. 

 Body elongate, feebly rhomboidal, feebly convex, shining, rufo- 

 testaceous in color, the pronotum with an elongate nubilous discal 

 black spot at each side; pubescence yellowish, short but abundant, 

 coarse and distinct, usually rather long medio-basally on the elytra, 

 longer and dense beneath, except on the abdomen; head closely, 

 moderately punctate, the sides as well as apex of the clypeus dis- 

 tinctly elevated, the clypeus subquadrate, shorter than wide, with 

 short sparse hairs, those of the vertex long and dense; prothorax 

 trapezoidal, the sides medially obtusely angulate, thence to the base 

 distinctly sinuate and diverging ; basal angles obtuse but not rounded ; 

 sides yellow-tomentose, the punctures moderate, gradually sparse 

 medially, dense but not larger toward the sides, where they are
