ELTTEOSPH^EA. 261 



and produced into a short tooth, surface very closely punctured, the interstices somewhat rugose, more 

 especially at the sides ; scutellum broadly triangular ; elytra widened towards the middle, geminate 

 punctate- striate, testaceous, their epipleurae and the sutural and lateral margins blackish green, a large 

 subtriangular patch of the same colour extends from the base to the middle, and has its posterior edge 

 cut oblique at each side, another still larger patch of a more regular triangular shape extends to nearly 

 the apex, the anterior edge of this patch is concave ; underside and legs greenish black.

The depth of the punctuation varies in this species, being sometimes almost obsolete ; 

 the elytral sutural band is narrowed at the base, but is widened almost directly below 

 the latter, and continues in that shape to the apex ; the patches of the elytra occupy 

 the greater part, so that only a narrow space of testaceous is seen between them and 

 near the margins. I have retained the manuscript name given to it by Deyrolle. 



2. Elytrosphaera mexicana. (Tab. XV. fig. ?3.) 



Ovate, convex, black ; antennae and legs fulvo-piceous ; thorax and elytra rugose-punctate, the latter with the 

 base, the lateral margin, and three narrow transverse lines and two spots near the apex golden yellow. 



Length 3 lines. 



Head with a few fine punctures ; labrum fulvous ; antennas extending to one third the length of the elytra, 

 fulvous, the last four joints thickened, longer than broad ; thorax transverse, the sides distinctly rounded 

 anteriorly, longitudinally rugose and variolose punctate, disk closely but less strongly punctured, black ; 

 elytra irregularly and rather strongly punctured, the interstices rugose, black, the base and lateral 

 margin narrowly golden yellow ; an oblique stripe of the same colour runs from the shoulder towards the 

 sutural margin ; another, sinuate stripe extends across the middle and joins the marginal stripe where 

 the latter is convex for a short distance ; a third oblique stripe, angulate at its inner portion, is placed 

 below the middle, and two small spots of a ring-like shape near the apex ; a small spot further joins the 

 basal band near the scutellum ; and another one is placed between the two posterior bands near the suture ; 

 femora piceous, tibiae and tarsi fulvous. 



Hab. Mexico, Oaxaca (Boucard, coll. Salle). 



The shape and position of the golden lines on the elytra separate the present species 

 from others of similar coloration. In the single specimen before me none of the 

 transverse lines touch the suture, the marginal band is raised at the middle in a 

 short convex shape, upon which the central band is placed, and the first oblique stripe 

 is interrupted in its middle. The thorax is entirely black ; and this distinguishes the 

 species from its allies.
