rupted, although here and there running into each other, causing broader and irregular 
smooth spaces. | 
56. Cryptocephalus nigrofasciatus. 
Black, the basal joints of the antenne and the legs fulvous; above flavous; thorax with a N-shaped black 
mark ; elytra with a lateral transverse smooth space, strongly punctate, flavous, a broad irregular longi- 
tudinal band on the disc, constricted at the middle, and a subapical spot, black. 
Var. The elytral band almost obsolete. . 
Length 14 line. 
Head fulvous, sparingly punctured between the eyes, with a distinct central fovea; eyes but slightly sinuate, 
widely separated ; clypeus triangular ; antennz about half the length of the body, the lower four or five 
joints fulvous, the other joints black; thorax rather more than twice as broad as long, scarcely visibly 
punctured, flavous, with a large M\-shaped black mark, or black with the lateral and anterior margins and 
two spots at the base yellow; scutellum black; elytra rather strongly and regularly punctate-striate, the 
first (subsutural) row of punctures abbreviated below the middle and closely approaching the second row, 
this latter apparently joined at the apex to the two following rows, the fifth row turned outwards below 
the middle, limiting a smooth transverse space, and beyond this parallel and eventually joining the eighth, 
the sixth and seventh rows interrupted below the shoulder, the colour very variable—in well-marked 
specimens the dise almost entirely occupied by a broad black band which is strongly constricted at and 
abbreviated below the middle, this band being followed by a spot of variable size (placed at the junction 
of the striw), the lateral margin also narrowly black; underside black, with the sides of the ventral 
segments more or less testaceous ; legs entirely fulvous ; prosternum flavous, the posterior angles thickened 
and of blunt triangular shape. 
Hab. GuateMata, Quiche Mountains 8000 feet, Totonicapam 10,500 feet (Champion). 
The elytral pattern of this species is only well defined in one or two specimens: it is, 
no doubt, subject to great variation, as in the variety the black bands are indistinct. 
The North-American C. incertus, Oliv., seems to be somewhat closely allied, but differs 
in the coarsely punctured thorax and in having three bands on the elytra. 
57. Cryptocephalus undecimplagiatus. (Tab. XXXVII. fig. 23.) 
Black, the head, antenne, and legs fulvous; thorax impunctate, black, the anterior and lateral margins in 
part and two large spots at the base obscure fulvous; elytra scarcely visibly punctate, each with two spots 
at the middle, and one at the apex, pale fulvous. 
Length 13-13 line. 
Head impunetate, obscure fulvous ; mandibles black ; antenne two-thirds the length of the body, entirely 
fulvous ; thorax subconical, twice as broad as long, the sides strongly narrowed in front, greatly deflexed, 
and obliquely and very rapidly converging from the base, the posterior margin finely serrate, the surface 
quite smooth, fulvous, with a black M\-shaped mark (or, if the black is taken for the ground-colour, with 
five large fulvous spots—these consisting of a broad patch on the anterior margin and thestill broader one 
along the lateral margins and two large oblique spots at the base); scutellum longer than broad, with a fovea 
at the base; elytra scarcely twice as long as the thorax, broad, the punctures very minute (only visible 
under astrong lens) and placed widely apart, the sutural stria, and the ninth also, more deeply punctured, 
the surface black, with two large spots placed transversely across the middle of the disc (one lateral and 
one near the suture), and a round spot at the apex, obscure fulvous; legs, prosternum, and last ventral 
segment obscure fulvous, the rest of the underside black. _ 
Hab. Guatemata, San Juan in Vera Paz (Champion). 
C. undecimplagiatus is well distinguished from its allies by the elytra being very 
faintly punctured and with the spots of a dull flavous or fulvous colour.
