the lateral margins testaceous, but this colour narrowed at the base. 

 Scutellum impunctate. Elytra very convex towards their first half, 

 distinctly widened behind the middle, subgeminate-puuctate-striate 

 near the suture; rest of the surface confusedly punctate, the inter- 

 stices aciculate near the apex, of the same colour as the thorax ; the 

 lateral margins narrowly testaceous and impunctate. Underside and 

 legs black, the latter rather slender ; mesosternal process long and 

 slightly curved. 



Tliis species resembles much in colour D . jlavomarginata, Jacoby, 

 but is much larger, more convex, and more strongly punctured on the 

 elytra : the yellow margin of the thorax also is much narrower ; and 

 the colour of the legs is uniform, instead of being black and tes- 

 taceous as in D. flavomarginata. 



57. DoRYPHORA CONNEXA, Sp. UOV. 



Broadly ovate. Greenish seneous ; thorax remotely punctate ; 

 elytra distinctly geminate-punctate-striate ; flavous, the suture, a 

 transverse irregular-shaped band before the middle, common to both 

 elytra, and four large spots behind the middle of each elytron 

 metallic green. 



Length 6 lines. 



Head remotely and finely punctate, labrum testaceous. AntenuBe 

 rather short, extending a little further than the base of the thorax; 

 the last five joints transverse ; four basal joints metallic green, the 

 rest black. Thorax scarcely widened in the middle, sides nearly 

 straight ; surface with rather deep but distant punctures, forming a 

 closely punctate row near the lateral and posteiior margin, greenish 

 seneous, subopaque. Elytra wider at the base than the thorax, 

 convex, regularly ovate-rotundate, deeply geminate-punctate-stiiate, 

 the punctures less strongly impressed near the apex, and the striae 

 somewhat irregular ; liglit flavous; each elytron with four metallic 

 green spots behind the middle, of which the anterior ones are much 

 larger than the others, subquadrate, the posterior ones elongate and 

 placed obliquely, neither of them touching the lateral or the sutural 

 margin ; a broad transverse band extends also across the disk below 

 the base connected with the suture, near which it is deeply dentate 

 at its anterior margin. 



This species is not unlike D._/«>!eJr25 (supra, p. 597), but is much 

 more rounded in shape, the punctured elylral striae are deeper and 

 visible to the apex, and the shape of the spots also is different. 



58. DoRYPHORA SELECTA, Erichs. 



The Ecuador specimens vary somewhat from, the type ; there are 

 three small spots on the elytra — one at the base near the shoulder, 

 one near the suture before, the other behind the middle ; but I con- 

 sider them to be but local varieties, as in all other respects they are 

 similar to Erichson's species.
