punctures ; the suture has also at its posterior part a deeply im- 

 pressed liae running parallel with it at each side. The elytra are 

 of a light flavous, shining, the entire suture greenish or bluish 

 black, which colour is gradually narrowed towards the apex. Under- 

 side and legs black with a bluish tint. 



Hab. Columbia. 



In colour this species approaches close to D. limbatipennis, Stal ; 

 but the want of the outer marginal vittae, together with the roundish 

 shape, will distinguish the species before us from the above insect. 



16. DORYPHORA VITTAT1PENNIS, Sp. 110V. 



Black. Head and thorax opaque. Elytra strongly semipunctate- 

 striate, black, shining ; each elytron with five narrow longitudinal 

 flavous stripes. 



Length 6 lines. 



Head finely punctate ; antennae black, shining. Thorax deeply 

 and irregular punctured, the intervals partly convex; sides narrowed 

 at the base, from there rounded to the apex. Scutellum smooth, 

 triangular, black. Elytra parallel, convex, deeply punctate, striate 

 near the suture, more irregularly towards the sides ; black, shining, 

 each elytron with five narrow flavous vittae at equal distances from 

 each other, of which the outer one is the broadest, all of which are 

 confluent at the apex and extending to the base. Underside and legs 

 black. 



Var. Elytra with only the outer vittse entire, the sutural one only 

 visible at the posterior third, the other stripes entirely absent or 

 only partially visible near the apex. 



Hab. Columbia.

17. Dorypiiora porosa, sp. nov. 



Broadly ovate, very convex, piceous below. Head aud disk of 

 thorax black ; sides of latter testaceous. Elytra deeply foveolate, 

 the intervals irregular transversely reticulate, dark brown. 



Length 7 lines. 



Head opaque, with a few very minute punctures ; antennae long, 

 scarcely thickened towards the apex, fuscous. Thorax with the 

 anterior and posterior margin parallel in the middle, the anterior 

 angles acute and much produced, the sides much flattened and 

 slightly thickened ; disk minutely punctate, of the same colour as 

 the head, the sides light testaceous, impunctate. Scutellum 

 broad, smooth, piceous. Elytra couvex at their first third, thence 

 suddenly declining and subdepiessed towards the apex, uniformly 

 dark brown ; the suture shining, piceous, smooth ; surface deeply 

 punctate, striate near the suture, foveolate towards the sides, the 

 intervals raised and connected partially by transverse short costse, 

 forming a kind of network towards the sides. Femora greenish 

 aeneous ; tibiae piceous.
