apex, black ; in flexed limb of the elytra black ; the two anterior pair 

 of legs of the same colour. Underside and posterior legs fulvous. 



Sufficiently distinguished from quinquevittata by the colour of tbe 

 underside and the position of the lateral elytral stripe, which covers the 

 lateral margin instead of running parallel to it, as in the former species. 



Collections of Godman and Salviu and my own. 



18. (Edionychis crucigera, sp. uov. (Plate XVIII. fig. 4.) 

 Ovate, convex. Piceous below, above yellowish white ; a broad 



transverse band across the middle, a narrow one near the apex and 

 another at the extreme base of the elytra as well as the suture 

 narrowly purplish metallic. 



Length 4 lines. 



Hah. Brazil. 



Head distinctly foveolate between the eyes, black ; inner orbit of 

 the eyes fulvous ; three basal and the apical joint of the antennae 

 obscure fulvous. Anteiior angles of thorax slightly produced into 

 a short rounded tooth ; sides straight at the base, rounded towards 

 the apex ; surface impunctate. Scutellum black. Elytra convex, 

 nearly parallel, closely and finely punctured ; the median transverse 

 baud straight and broad, connected narrowly by the suture with 

 another very narrow band near the apex, and a still narrower one at 

 the extreme base, none of these bands touching the lateral margins. 

 Underside and legs piceous, stained here and there with dark brown. 



A specimen which I take for a variety has the posterior band 

 enlarged into a triangular patch, which occupies the entire apex, and 

 extends upwards along the lateral margin. 



In my collection, 



19. ffiDioNYCHis variegata, sp. uov. (Plate XVIIl. fig. 5.) 

 (E. clavicornis, Clark, MS. 



Broadly ovate, convex. Fulvous or dark brown below ; above light 

 fulvous or flavous ; four apical joints of the antennae, lateral margins 

 and five spots of the thorax, and two or three broad, irregularly- 

 shaped, transverse bands of the elytra black. 



Length 3^-4 lines. 



Hat. Brazil. 



Head minutely granulate ; eucarpse not distinct ; carina triangu- 

 lar, widened anteriorly ; antennae short, the apical joints transverse, 

 broader than long, fourth joint the longest. Thorax more than 

 t-hree times as broad as long ; posterior margin distinctly sinuate ; 

 sides round, flattened, their anterior angles much thickened, but not 

 produced ; surface minutely granulate, like the head, and covered 

 with very small punctures, flavous ; three small spots in the middle 

 of the disk near the base, and two above them, as well as the ex- 

 treme lateral margins, black. Scutellum flavous. Elytra widened 

 in the middle, pointed at the apex ; surface granulate and punc- 

 tured, like the thorax ; a broad, transverse, basal band, widened pos- 

 teriorly at the suture, and having attached to it at each side a round 

 spot, black ; another bidentate broad band occupies the middle, aud
