CRY PTOCEPHALUS. 121 
58. Cryptocephalus problematicus. (Tab. XX XVII. fig. 24.) 
Reddish-fulvous, the sides of the breast, the apex of the femora, and the tibia piceous ; thorax impunctate ; elytra 
strongly punctured, each with two spots at the base and another at the apex, and a short transverse band 
below the middle, black. 
Length 14-2 lines. 
Head fulvous, with a deep longitudinal depression on the vertex, the lower portion with a few punctures, the 
space between the points of insertion of the antenne with a deep transverse groove, the eyes rather closely 
approached ; antenne black, the basal four joints fulvous; thorax nearly three times wider than long, 
the sides finely marginate and rather distinctly rounded, the surface entirely impunctate, fulvous ; scutellum 
scarcely longer than broad, foveolate at the base, fulvous, margined with piceous ; elytra broad, not very 
convex, slightly narrowed posteriorly, the punctured stria deep and regular and rather wide apart, the 
third, fourth, and fifth a little closer together than the others, the sixth and seventh only indicated 
by a few separate punctures, the lateral lobe feeble, each elytron with four black spots—one at the 
shoulder, a more transversely-shaped one near the scutellum, a smaller one at the junction of the fifth 
and eighth strie, and a short transverse band, not extending to either margin, below the middle; the 
knees, tibiz, and tarsi black, the breast more or less piceous and strongly punctured ; prosternum strongly 
produced anteriorly into a cup-shaped protuberance. 
Hab. Muxico, Cerro de Plumas (Hége). 
Somewhat allied to C. quaternarius, Suffr., but differing from that species in its reddish 
colour and in the number and position of the elytral spots. 
59. Cryptocephalus admirabilis. (Tab. XX XVII. fig. 25.) 
Fulvous, the apical joints of the antennae, the apex of the tibia, and the tarsi, black; above dark brown; 
thorax extremely finely longitudinally strigose ; elytra with all the interspaces between the rows of coarse 
punctures very strongly longitudinally costate. 
Length 17 line. 
Head fulvous, not visibly punctured; the eyes contiguous at the vertex, the space between the points of inser- 
tion of the antennz with a depression ; mandibles black; antennz slender, extending to the end of the 
elytra *, black, the lower four joints fulvous, the third and following joints very elongate ; thorax more 
than twice as broad as long, the sides rounded, very distinctly margined, and with a fovea placed at some 
distance within the margin at about the middle, the base with a deep oblique depression on each side near — 
the scutellum, the disc (when viewed under a strong lens) extremely closely and finely longitudinally 
strigose (giving the surface a silky gloss with whitish reflections) ; scutellum very narrowly elongate ; 
elytra narrowed posteriorly, castaneous, the interspaces between the rows of coarse punctures occupied by 
strongly raised longitudinal coste which are interrupted for a little distance below the shoulder, the 
punctures often connected by transversely raised spaces. 
Hab. Panama, Bugaba (Champion). 
Of this most interesting species only a single specimen was obtained by Mr. Cham- 
pion. It belongs, without doubt, to Suffrian’s seventeenth group, being evidently allied 
to the Brazilian C. dar, Fabr., and C. carneolus, Perty; it differs, however, from both 
these in having the thorax extremely finely strigose (instead of punctured) and ofa 
somewhat purplish-brown colour with light reflections. The elytral cost are here and 
there interrupted, but are for the most part joined near the apex: our figure will give 
a better idea of their shape. 
* These organs are incorrectly drawn in our figure.
