CETONIIN/E 317 



Elytra with solid black vittae. Body elongate-rhomboidal, stouter and 

 with nearly parallel hind body in the female, deep black, opaque 

 above, shining beneath, the head shining, unevenly, moderately 

 closely punctate, the clypeus rufescent at base, strongly (cf) or 

 moderately (9) reflexed at apex; pronotum having the sides and a 

 medial vitta pale yellowish, the sides rather angulate beyond the 

 middle, thence but feebly diverging to the base, the sinus of the latter 

 extremely shallow and indefinitely limited; punctures minute and 

 remote, becoming barely more distinct laterally, where there are a few 

 very small hairs; scutellum smooth, opaque, with a median pale vitta; 

 elytra elongate, with the costse obsolescent, very feebly convex; 

 punctures very fine and sparse, in part linear; each elytron has three 

 entire pale vittae, the middle one terminating at the junction of the 

 bounding black vittae posteriorly and sometimes partially interrupted 

 in the male; pygidium with the incised lines rather fine and sparse, the 

 surface longitudinally tumid medially, especially in the male, having 

 very short pale hairs and a large discal tomentose spot at each side; 

 under surface with large areas of tomentum toward the sides, much 

 reduced in the female; sterna with very moderate pubescence. 

 Length (cf 9 ) 11.0-13.0 mm.; width 5.9-7.3 mm. Mexico (Chiapas)

*geminata Chev. 



Elytra with comminuted dark spots. Body slender, elongate-rhomboidal, 

 moderately convex, opaque, pale yellowish-brown above, piceous and 

 shining beneath, the legs dark rufous; pubescence of the head and 

 pronotum, especially toward the sides, distinct, moderately long and 

 coarse, of the elytra sparse, short and coarse, of the sterna and sides 

 of the abdomen long, coarse, dense and conspicuous; head shining, 

 rather strongly and closely punctate, the clypeus reflexed at apex, 

 the sinus shallow but distinct; prothorax small, only a little wider 

 than long, the sides subparallel or but feebly, anteriorly converging 

 in basal three-fifths; base broadly arcuate, with barely a trace of an 

 undefined sinuosity at the middle; punctures fine and very sparse 

 throughout; surface with two broad black vittae, not attaining the 

 base, and a small black spot near each side; apical margin very 

 vaguely tumid at the middle; scutellum sharply pointed, smooth, 

 tawny-yellow throughout; elytra distinctly cuneiform, much wider 

 than the prothorax, elongate, very finely, sparsely, indistinctly and 

 in part linearly punctate, the costae broad and extremely indefinite, 

 very faintly convex as in geminata, the small dark spots very irregular 

 in form, aggregated along the suture and each costa, elsewhere 

 wanting; pygidium convex, loosely vermiculato-lineate, distinctly 

 and coarsely pubescent, neither it nor any part of the under surface 

 tomentose; anterior tibiae (cf ) slender, the upper tooth very obtuse 

 and vestigial, the two lower very feeble and obtuse; hind tarsi rather 

 stout and as long as the tibiae. Length (cf ) 11.3-11.9 mm.; width 

 5.5-6.2 mm. Arizona (Santa Rita and Baboquivari Mts.).
