992 MR. M. JACOBY ON PHYTOPHAGOUS COLEOPTERA. [Dec. 3, 



Elytra geminate-punctate-striate, fuscous ; two large round spots 

 near the scutellum, four others placed transversely, and the apex 

 broadly flavous, the latter with a small fuscous spot. 



Length 5 lines. 



Head minutely punctured, flat, with an indistinct piceous mark 

 at the vertex ; antennae testaceous, slightly thickened towards their 

 apex, terminal joint scarcely longer than broad. Thorax narrow, 

 sides rounded in front, anterior angles scarcely produced ; above 

 much more strongly (but not closely) punctured than the head, of 

 a rather indistinct testaceous colour ; four spots placed transversely 

 on the disk, the middle ones, which are in shape of two short 

 longitudinal vittae, of a greenish piceous colour. Scutellum testa- 

 ceous. Elytra slightly broader at the base than the thorax, very 

 convex on the disk, their apex regularly rounded ; the surface 

 rather finely punctate-striate, consisting of double rows of punctures, 

 which are more deeply impressed on the disk than at the base or 

 the apex ; the flavous patches on the disk of each elytron arranged 

 as follows, viz. one in the middle of the base, two transversely, of 

 which the outer larger one is placed immediately below the shoulder, 

 the inner one on the middle near the suture, the fourth occupying 

 the apex to nearly a third of the length of the elytra, having its 

 inner margin sinuate, and in its interior a small fuscous square spot. 

 Underside and legs testaceous. Mesosternal spine rather short, 

 slightly curved. 



Hab. Costa Rica? 



My collection. 



Closely approaching in colouring to D. cestuans, Lin., the species 

 described here is distinguished by its much larger size and by the 

 four spots on the thorax. 



21. DORYPHORA DECORATA, Sp. nOV. 



Ovate, convex, testaceous. Head with the base, thorax with 

 two vittae black. Elytra geminate-punctate-striate, testaceous, with 

 three transverse metallic green fasciae and a longitudinal vitta between 

 the second and third bands. 



Length 5 k lines. 



Head minutely punctate, with a shallow transverse depression and 

 an obscure longitudinal groove, testaceous, with an irregular trans- 

 verse bifurcate patch on the vertex ; antennae longer than the thorax, 

 gradually thickened towards the apex, as well as the palpi, testaceous ; 

 apex of mandibulae black. Thorax with a longitudinal depression 

 parallel with the lateral margins, the latter regularly rounded ; 

 surface very sparingly but rather deeply punctate, shining testaceous, 

 with two longitudinal black vittae from the apex to the base, slightly 

 curved outwards, and connected at the base by a very narrow band. 

 Scutellum impunctate, testaceous. Elytra regularly geminate-punctate- 

 striate near the suture, more coufusedly towards the sides ; shining 

 testaceous, the suture, an obliquely placed transverse band from the 

 shoulder to the suture a little below the scutellum (with its posterior 

 margin denticulate and connected by a narrow stripe at the lateral
