CETONIIN^E 327 



tered punctures basally, except at the sides; elytra slightly wider 

 than the prothorax, much wider at the humeri, arcuately narrowed 

 apically; punctures wanting in the opaque area, in the form of trans- 

 verse incised lines on the flanks, the intervals between the costse 

 each \vith two entire fine incised longitudinal lines; sutural margins 

 strongly elevated and polished; pygidium obtusely umbonate at 

 apical third, rather closely, concentrically strigose; anterior tibial 

 teeth equally spaced. Length (cf ) 9.3 mm.; width 5.0 mm. Hon- 

 duras. [Cetonia thelasco and montesuma (Mexico) G. & P.] 



*thelasco G. & P. 



Elytra with more strongly convex costae, which however become less 

 apparently elevated in the opaque areas 3 



3 Body narrowly oblong-suboval, not so rhombiform as in the preceding 

 and with relatively less prominent humeri; pubescence long and 

 coarse, generally fulvous, conspicuous on the pronotum; head densely 

 and finely punctured, the flat clypeus not at all margined, barely 

 reflexed at the bilobed apex; pronotum finely, deeply, closely punc- 

 tate, the punctures forming long oblique lines laterally; scutellum 

 well developed, in large part confusedly punctate; elytra more or 

 less elongate, the deep sulci finely punctate and w r ith longitudinal 

 incised lines, the flanks with the punctures small and well separated 

 before, transversely lunate behind, the post-median transverse spot 

 of tomentum; color wholly black and shining throughout, to nu- 

 bilously red from the humeri nearly to the suture behind the middle; 

 pygidium generally with a moderate spot of tomentum near each 

 side; teeth of the anterior tibiae very oblique, sharply pointed and 

 subequidistant. Length (cf 9 ) 10.0-10.5 rnm.; width 5.7-5.8 mm.

 [ Cetonia pulchella and fcrrugata G. & P.] *pulchella G. & P. 



Body still narrower and more elongate, the humeri small and not very 

 conspicuous at the sides, black, shining, the pubescence long, coarse 

 and fulvous as in pidchella, the flat and similarly densely and rather 

 finely punctate clypeus rather more rapidly acuminate, with the apex 

 narrowly and feebly sinuato-truncate; prothorax fully a fourth wider 

 than long, the sides subparallel basally, oblique apically, the apex 

 barely half as wide as the base, feebly sinuate, the basal sinus dis- 

 tinct; punctures small, deep, close, forming oblique lines, wanting at 

 base and along the median line behind about the middle; scutellum 

 as in pulchella but notably narrower; elytra longer, fully two-fifths 

 longer than wide, the sulci impunctate but each having the two long 

 incised lines distinct, shining, black, each with a large and oblique, 

 very opaque red area, from the humerus to near the suture from basal 

 third to behind the middle, with a black emargination opposite the 

 end of the scutellum, this opaque area obliterating all sculpture as it 

 does also in thelasco; flanks finely punctured below the opaque area 

 and, behind the post-medial transverse tomentose spot, becoming 

 very coarsely, deeply and rather closely, transversely incised; apical 

 part with two subsutural and one external transverse tomentose 

 spots; pygidium evenly convex and concentrically finely strigose, 

 without tomentose spots and w r ith coarse pubescence; anterior tibiae
