306 MEMOIRS ON THE COLEOPTERA 



shallower and denser and more disposed to oblique linear coalescence; 

 scutellum differing in having the punctures much finer and confined 

 to a more or less definite line parallel to the sides throughout the 

 length; elytra sculptured as in the two preceding and with similar 

 spots of tomentum and longitudinal incised lines near the suture; 

 pygidium with rather finer and still less approximate, irregular 

 incised lines, feebly umbonate near apical third (cf), or very feebly 

 and uniformly convex (9), the lateral spots of tomentum very 

 fragmentary in both sexes; abdominal series composed of much 

 smaller spots of tomentum, which are sometimes wanting. Length 

 (4 d\ 5 9 ) 11.8-13.0 mm.; width 7.0-7.5 mm. Mexico (Rio Balsas, 

 Guerrero and Cuernavaca, Morelos), Wickham. [Cetonia rufina

io Form (9) oblong-oval, moderately convex, polished green above, 

 the elytra opaque and more obscure green, sometimes with reddish 

 clouding, and having numerous small white tomentose spots, widely 

 and very irregularly distributed, one near the middle of the flanks 

 rather obliquely linear; under surface polished vitreous-green, the 

 sterna with sparse moderate hairs; head with the front strongly, 

 closely punctate, rather elevated along the median line, the clypeus 

 less strongly, sparsely punctate, with strongly reflexed sides and 

 apex; prothorax a third wider than long, the sides rounded at the 

 middle; punctures small but strong, sparse, coarse and bearing very 

 minute hairs toward the sides; scutellum sharply triangular, punc- 

 tureless, opaque, with polished basal part; elytra glabrous, oblong, 

 barely narrowed posteriorly, the costse very feeble, the surface almost 

 punctureless but with some coarse incised wavy lines apically; 

 sutural convexity becoming sharply cariniform apically, the sutural 

 angles however obtuse; pygidium with very confused close incised 

 lines and sparse short hairs, obtusely tumescent very near the apex 

 in the female; legs stout, the hind tarsi short, thick and compressed. 

 Length (9) 19.2 mm.; width 10.4 mm. Mexico. [ Cetonia lesueuri 

 (and latreillei?) G. & P. and notulata Chev.] *lesueuri G. & P. 



Form ( 9 ) oblong-oval, evenly and moderately convex, dull coppery- 

 brown, the head shining black, the pronotum gradually feebly shining 

 toward the sides; elytra opaque, black, with many small pale brown- 

 ish-red maculae throughout, wholly devoid of tomentose spots, the 

 pygidium densely wavy-rugose, the rugae shining metallic-black, 

 having sparse pale hairs and a large white spot of tomentum near 

 each side, the surface feebly convex; under surface and legs shining, 

 the sterna and legs with feeble reddish, the abdomen with greenish- 

 black, lustre, without trace of tomentose spots; head rather strongly, 

 closely punctate, the clypeus with widely spaced transverse wavy 

 rugae, the frontal hairs sparse, extremely short and thick, the clypeal 

 apex as in lesueuri; occiput smooth, strongly convex, with no tubercle 

 anywhere visible; prothorax a third wider than long, the converging 

 sides broadly, subevenly arcuate, the bead very coarse and convex; 

 punctures sparse, rather strong, becoming large and close but ar- 

 cuate toward the sides; scutellum pointed, smooth and opaque; 

 elytra oblong, not evidently narrowed posteriorly, the apex very
