THE CANADIAN ENTOMOLOGIST. 11 



middle of the first three segments of the abdomen, which are yellow (the 

 black edge of these segments is about 1^2 mm. wide), legs with tibiae and 

 tarsi black, coxae and femora yellow, with apex of the hind pair piceous. 

 The form is very slightly dilated at the rear. The type specimen has the 

 plication of the elytra slight but well marked. In addition to this speci- 

 men I separate another example marked by Jacoby as Lacordairei, 

 labelled "Amaz.," which seems to be a c? , and has the joints 2-3 of the 

 antennae equal and the plication very slight ; the colouring and form, 

 however, are precisely similar. Should be placed in § A, Baly's paper ; 

 the coloration of the abdomen easily distinguishes it. 



D. sajicaiarina^ nov. sp. 



Head black, antennae dark, with three basal and three upper joints 

 flavous, thorax yellow, smooth, shining, elytra not plicate, black, tinged 

 with greenish, shining, punctured, with the lateral margin, extreme apex 

 excepted, and basal and apical round spots and median transverse spot 

 flavous, below yellow, wiih pectus, tibiae and tarsi bl?ck. Length 6^ mm. 



Four examples from St. Catharina, Brazil (Mr. Klages). 



$ antennae three-fourths as long as body, joints 2-3 short, equal, 4 

 almost twice as long as both combined; shorter in $, with the joint 3 

 one-half longer than 2, and 4 not twice as long as both combined, three 

 upper and three lower joints flavous, the tip of the last piceous, thorax 

 one-half broader than long, convex, shining, impunctate on the disk, scutel 

 dark piceous, elytra shining, evenly and strongly punctured, slightly 

 depressed along the suture at base, the epipleurae and inflexed margin 

 yellow, the flavous colour vanishing when it reaches a point just behind 

 the apical spot, which is round and equidistant from the suture and 

 margin, the basal spot is round, discal and near the suture, the transverse 

 spot is behind the middle and oblique, not attaining either the side or 

 suture ; one of my specimens has the elytra very obsoletely subplicate ; 

 belongs in § A, Baly. 



D./unerea, nov. sp. (Jac. in litt.).
