THE CANADIAN ENTOMOLOGIST. 57 



D. septemplagiata nov. sp. 



Head prasinous, with black labrum and piceous vertex, the fovea on 

 top, very large and well marked ; antennae black, prasinous at base, tenth 

 joint white ; thorax prasinous, convex, shining, sparsely but distinctly 

 punctured, and with three obsolete fovei^, scutel black ; elytra prasinous, 

 plicate, punctured, the disk longitudinally, obsoletely yellow from the 

 base to near the apex, two spots at the base of each elytron, one common 

 wedge-shaped sutural, the other small humeral; also two small round 

 discal spots, one about the middle and the other directly behind on the 

 convexity, all black ; body below and legs yellow prasinous, tibiae and 

 tarsi black. Length, 7 mm. 



One ^ example, S. Catharine (Liiderwoldt). 



Antennae filiform, about three-quarters the length of the body, joint 2 

 short, 3 a trifle longer, 4 longer than both together, 9-10 white, base of 

 II more or less white; the sides of the thorax are much rounded in front 

 of the middle and nearly straight behind ; the elytra are moderately 

 dilated behind, shiny, thickly and strongly punctured, even a little con- 

 fluently, along the suture forward ; the depression back of the scutel is 

 distinct but not noticeably great ; the four round black spots on the disk, 

 two on each side, are placed on a yellowish-green ground, so as to form 

 the corners of a square, : :, and are the most noticeable thing about the 

 species. 



D. delrio, nov. sp. 



Head prasinous, with piceous labrum and mouth, and black eyes ; 

 antennae fuscous, prasinous at base; thorax prasinous, convex, shiny, 

 impunctate, scutel piceous ; elytra prasinous, plicate, with three flavous 

 spots, the first basal, median, elongate, a trifle more than one-third the 

 elytral length, the second submedian, transverse, slightly oblique, and a 

 little nearer the suture than the mirgm, the third apical, round, equidistant 

 from the suture and margin ; below and legs flavous, with the thorax 

 prasinous and tibia tinctured with prasinous. Length, 5 mm. 



One ^ (?), Rio de Janeiro. 



Antennae about three-fourths length of body, joint 2 short, 3 scarcely 

 one-half longer, 4 longer than the two preceding, thorax a trifle broader 

 than longer, very slightly sinuate, elytra barely dilated behind, with one or 

 two sulcations indicated on the disk of the elytra, punctuation fine and 

 rather sparse. Among the green species this will come near selecta Jac- 

 2iW^ glancma Baly, but these, however, have the basal yellow spot humeral, 

 liere it is strictly median, and does not encroach on the humeral knob.
