upward to the scutel, the scatellar being wedge-shaped, the apical lunula 

 ends at equal distance fro.^i the suture and margin ; the punctuation is 

 moderate and thick. 



Very like some of the forms of septemliturata Er., but readily 

 separated by the not plicate elytra. 



D. darkeliita^ nov. sp. 



Head black, antennoe a little more than one-half length of the body, 

 black, last two joints yellow, z-t^ short, nearly equal, 4 slightly longer than 

 both together; thorax rufous, convex, smooth, shining, obsoletely bifoveate, 

 scutel ruftHis; elytra honey-yellow, plicate, shining, wiih three short, broad, 

 even cyaneous vittae at the base, one common sulural, the other humeral, 

 covering the anterior third, also on each elytra two similar spots at the 

 rear, one nearly round median, the other sublateral oblong, both on the 

 convexity ; body below and legs yellow, ])ectus black. L,ength, 5^^ mm. 



One example, St. Catharine, Brazil, sent me by Mr. Klages. 



Will be placed near dysoni Baly, from which it is easily distinguished 

 by the three short, even cyaneous vittae in front, and the antennae with 

 last two joints yellow. The thorax is longer than broad, faintly sinuate, 

 nearly parallel; the elytra are rather closely punctate, and have a tendency 

 to be slightly corrugated, and the cyaneous vitt?e at the base are not 

 narrowed behind but are rather abruptly truncate. 



D. hcenderwaldti^ nov. sp. 



Form almost parallel, head black, antennae black, with the three lower 

 and two upper joints flavous ; thorax pale flavous, convex, smooth ( $ ), 

 irapunctate on the disk, scutel black, elytra pale flavous, plicate, thickly, 

 finely punctured, three spots at the base, one common sutural wedge- 

 shaped, one humeral, the latter prolonged to a point just beyond the 

 middle, and a large round spot near the apex black ; below and legs 

 flavous, pectus black. Length, 5^ mm. 



Two examples, St. Ca-tarina, Liinderwaldt ; one St. Catharine, Brazil, 

 Klages. 



The antennse ( (? ) about three-fourths the length of the body, joints 

 2-3 equal, 4 one-third longer than the preceding two ; in the $ antennae 

 3 is longer than 2, and 4 equal the two preceding, the thorax is a little 

 wider than long, sides nearly parallel, and with a few punctures at the 

 sides ; the plication of the elytra is strong and extends nearly to the con- 

 vexity, the punctuation is thick and even, the reflexed edge is marked and 

 wide, the sutural spot is about one-fourth of the length of the elytra, the
