Nesogena (/igantea (Falrin. i. 1.), n. sp. 



Oval-elliptic; gTeeiiish-brouzcd or brown-bronzed, less 

 nitid on the prothorax ; head bluish-green and coppery, 

 very nitid, irregularly punctured, a groove at each side 

 the front connected posteriorly (between the eyes) by an 

 arched impression ; prothorax moderately convex, feebly 

 eniarginate in front, sides ver}^ strongly curvedly expanded 

 fi'oni the apex to behind the middle, thence subparallel to 

 the base ; front angles obtuse, the hind directed back- 

 wards ; moderately and irregularly punctured, most 

 closely so on the sides, smooth down the median line ; 

 lateral margins rather broad, bluish, coarsely rugose- 

 punctate ; the usual coarsely rugose-punctate line across 

 the middle of the base, close to the margin ; scutcllum 

 blue, punctured, triangular with the sides sinuate ; 

 elytra ample, moderately convex, broadest before the 

 middle, a little narroAved behind, apex (conjointly) rather 

 broadly rounded, sides broadly margined, bluish, a little 

 sinuous, and narrowing at base and apex ; punctate- 

 striate, the stria3 w^ell marked, the punctures very small, 

 except at the base, and crenating the sides of the inter- 

 vals ; these are convex, finely punctured, delicately alu- 

 taceous, most closely so at the sides : underside more or 

 less bright coppery-jEneons ; flanks of prothorax longi- 

 tudinallv undulately wrinkled ; prosternum horizontal, 

 produced and narrowly conical (mucronate) behind; legs 

 bluish-black; antenna} long, tapering outwardly, the basal 

 joints dark shining brown, the rest paler. 



Long. 12—12^ lin. 



Nesogena speciusa, n. sp. 



Near Batesii (Fairm. Stett. Ent. Zeit. 1875, p. 190), 

 but smaller ; the prothorax chalybeate-blue, sometimes 

 blended with violet, more strongly and more closely 

 punctured, the transverse basal impression shallower; the 

 sides more aljruptl}- (less curvedly), narrowed anteriorly ; 

 the elytra brilliant (especially in the ? ), purplish-coppery, 

 becoming golden-Eeneous at the margins, base, suture and 

 down the stritB; the strire distinctly broader, more strongly 

 crenating the sides of the intervals ; legs and basal joints 

 of antenn;\3 uniformly dark shining brown. 



These dilfcrences a])pcar slight, but they are constant 

 throughout a series of examples.
