the middle, of seven tubercles, each gradually smaller to the apex, 

 the second of seven, including one at the base nearer the suture, 

 the outer row of eight, the last three much the smallest, the 

 interstices rather closely and coarsely punctured, at the base a 

 common bilobed and just before the middle a quadrate spot com- 

 posed of short erect umber hairs ; legs dotted with long white setae. 



Allied to B. buccellaria (the type of the genus), but, 

 inter alia, with a narrower head and prothorax, the 

 latter longer than broad, and the elytra quadrate, with 

 the tubercles mammilliform. 



Byrsops plumbea. (PI. XL, fig. 7). 

 B. ovata, nigra, squamis minutis albidis confertim vestita, ad 

 latera elytrorum maculis plurimis niveis omata ; rostro breve, 

 angusto, subgibboso, impunctato ; elytris latis, modice convexis, 

 minus tuberculatis. Long. 3^ lin. 



Hab. Cape. 



Ovate, black, clothed above with minute, whitish, non-con- 

 tiguous scales ; head broad, convex in front, and with low super- 

 ciliary ridges ; rostrum short, narrow, gibbous in the middle, and 

 without grooves or punctures ; club of the antennae stout, and as 

 long as the funicle ; prothorax transverse, very slightly rounded at 

 the apex, the disc irregular, dotted with a few glossy black 

 granules ; scutellum transverse, covered with ferruginous hairs ; 

 elytra in the middle nearly twice as broad as the prothorax, with 

 numerous shallow punctures placed in irregular lines, each elytron 

 with two rows of tubercles, the inner with three, the middle with 

 five, and the outer with seven, the latter with the tubercles com- 

 pressed and continuous, between the outer and close to the middle 

 row a black stripe, the deflexed sides with well-limited spots com- 

 posed of snowy scales ; body beneath blackish, suture between 

 the two basal segments of the abdomen nearly obsolete ; legs 

 covered with whitish scales, and dotted with longish setae. 



The black derm just visible between the white scales, 

 which are also present in the punctures, especially on 

 the elytra, gives a leaden hue to this species. The spots 

 on the sides are probably liable to unite. 



Byrsops scapularis. 

 B. late subovata, indumento, vel squamis minutis, subnitide 

 griseis dense tecta ; rostro crasso, leviter foveato ; prothorace rude
