78 MEMOIRS ON THE COLEOPTERA 



Body large and broadly oblong-oval, pale brownish in color, with shining 

 pearly cupreous lustre above, the shining black under surface and 

 legs with strong cupreous lustre, becoming green at the sides of the 

 hind coxae; head large, fully three-fifths as wide as the prothorax, 

 the eyes somewhat prominent; surface densely punctate, sparsely 

 toward base; clypeus large, semicircular, gradually strongly reflexed 

 at apex but not at the sides, more than twice as wide as long; pro- 

 thorax twice as wide as long, nearly as in the preceding but with 

 more evenly rounded sides, the apical angles very acute and sharp, 

 the basal obtuse and distinctly rounded; basal lobe more distinctly 

 truncate at the scutellum, the ambient bead strong and not inter- 

 tupted even at the middle of the apex; punctures fine but deep, sparse, 

 becoming coarse but not dense toward the sides; elytra not more than 

 a fourth longer than wide, distinctly wider than the prothorax, 

 circularly rounded at apex, the sides behind the base ( 9 ) subex- 

 planate and much thickened; surface with the stria? broadly and 

 moderately impressed and coarsely, closely punctate basally, finely, 

 feebly and obsoletely punctulate posteriorly and laterally; punctures 

 of the broad second interval basally coarse and conspicuous; pygid- 

 ium black, with green lustre, very densely and transversely vermicu- 

 lato-rugose throughout in the female, the sixth ventral in that sex 

 slightly flattened, polished and almost sculptureless throughout, 

 broadly arcuate behind. Length (9) 30.0 mm.; width 15.5 mm. 

 Guatemala (Esquintla) *cuprascens n. sp. 



4 Form nearly as in the preceding but more narrowly elongate-oval, 

 the brownish-testaceous upper surface with feeble pearly-green 

 lustre, the pygidium and under surface dark, with rather bright 

 greenish lustre; legs slightly varicolored, metallic in lustre; male 

 paler in coloration than the female; head large, nearly similar in the 

 sexes, except that the sculpture is coarser and denser in the female 

 and the eyes a little larger and more convex in the male; clypeus 

 more than twice as wide as long, semicircular, the apex broadly, 

 feebly reflexed (cf), or more narrowly and strongly (9 ); prothorax 

 smaller and shorter than in the preceding, more than twice as wide 

 as long, the outline and beading nearly similar, the basal lobe not so 

 truncate at the scutellum; punctures fine but deep and sparse, 

 becoming coarse, close and irregularly confused laterally; scutellum 

 small, transversely semicircular; elytra a third (cf) to fourth (9) 

 longer than wide, more inflated at about basal third in the latter and 

 with more thickened subexplanate edges, continuing almost to the 

 apex but greatly diminishing, strongly rounded at apex; sculpture 

 of the same general type as in cuprascens but not quite so conspicu- 

 ous; pygidium more convex and nearly smooth except basally (cf ), 

 or densely vermiculato-rugulose ( 9 ) ; sexual characters nearly as 

 in the two preceding, the mesosternal process rather more slender 

 than in cuprascens. Length (cf 9 ) 24.0-28.0 mm.; width 12.3-15.0 

 mm. Honduras (San Pedro Sula). Five examples. . *strigosa Cast. 



Form and coloration nearly as in strigosa but smaller in size and more 

 uniformly testaceous, with faint pearly greenish lustre throughout 

 above, the head and pronotum not darker in shade than the elytra,
