margins, an oblique transverse band before, another more horizontal 

 baud behind the middle, fuscous or ferruginous. 



Length 4| lines. 



Var. a. The anterior transverse band of the elytra curved in form 

 of a crescent. 



Var. b. The dark colour of the elytra predominating, so as to sur- 

 round three flavous patches on each elytron. 



Var. c. Elytra fuscous, with eight flavous spots. 



Var. d. Elytra fuscous, with two large flavous patches. 



Head smooth, impunctate, with a large flavous patch in front, as 

 well as two small spots below the antennae of the same colonr. An- 

 tennae robust, black ; all the joints, with the exception of the second 

 one, which is very small, subequal. Thorax transversely convex, 

 laterally narrowly marginate ; the anterior angles not toothed, but 

 acutely produced almost to the end of the eyes, their apex much 

 thickened ; surface extremely finely punctate, almost smooth ; scu- 

 tellum small, piceous ; elytra also nearly impunctate, slightly nar- 

 rowed at the base, shining flavous ; the suture, to a greater or smaller 

 extent, the external margin, the base more or less, and two trans- 

 verse bands (one oblique before the middle, the second behind) 

 fuscous. 



In var. a the anterior band does not touch the suture, but curves 

 down and outwards, so as to form a crescent. In the other varieties 

 the dark colour predominates in one case to an extent so as to sur- 

 round four flavous patches on each elytron, in another variety leav- 

 ing only two large flavous spots, of which one is situated in the 

 middle near the lateral margin, the other near the apex. Underside 

 and legs black or dark brown, covered with yellowish pubescence ; 

 claw-joint moderately thickened. 



Hab. Venezuela, Columbia, Brazil ; var. d, Mexico. 



This species bears a close resemblance to M. S-guttata, Fab. ; but 

 the larger size, the colour of the transverse bands, and the absence 

 of the small shoulder-spot will distinguish it from that species. It 

 is also known in collections, I believe, under the MS. name of inso- 

 lita, Chev. ; 6-siffnata, Dej. 



6. HOMOPHOETA ALBOFASCIATA, Sp. nOV. 



Ovate, elongate, black, shining ; a frontal patch, two spots below 

 the antenna?, thorax and abdomen flavous testaceous or reddish 

 brown. Elytra metallic violaceous blue or black ; a slightly curved 

 transverse band across the middle, and a transverse subquadrate 

 patch near the apex of each elytron, white. 



Length 3 lines. 



Head bluish black, vertex impunctate, shining, a row of rather 

 deep punctures round the orbit of the eyes, a transverse spot be- 

 tween the latter testaceous ; antennae rather short, black, base of 

 the second joint testaceous. Thorax with the lateral margins 

 slightly sinuate, the anterior angles produced and thickened, and 

 the posterior margin distinctly and obliquely sinuate at each side ; 

 surface impunctate j scutellum black, smooth ; elytra convex, mar-
