CRYPTOCEPHALUS. | 119 
In the female the oblique impression on each side of the base of the thorax is much 
more strongly marked than in the male. 
54. Cryptocephalus flavomaculatus. (Tab. XXXVIIL. fig. 3.) 
Black ; the head, the anterior and lateral margins of the thorax, and two spots at the base of the latter, yellow ; 
elytra deeply punctate-striate, black, each with five yellow spots (1.2.1.1), the two apical ones transverse ; 
femora yellow beneath, 
Length 13 line. . 
Head with a few punctures, the vertex black and impressed with a longitudinal groove, the rest of the surface 
(except round the base of the antenne) yellow ; labrum piceous ; mandibles black; antenng black, the 
lower four joints flavous ; thorax twice as broad as long, black, the anterior margins narrowly, the lateral 
margins broadly (but interrupted at the middle by a short transverse black streak), flavous, the base 
with two transversely-shaped yellow spots, the surface with a few scarcely visible punctures, the posterior 
margin finely serrate ; scutellum rather short, its apex truncate; elytra with very deep and closely placed 
punctures, the sixth and seventh rows interrupted below the shoulder by a smooth transverse space, the 
lateral interstices strongly costate, the yellow markings arranged thus—a spot at the middle of the base, 
two spots, more transversely-shaped, at the middle (the outer one extending upwards along the lateral 
margin to the base), and a short band near and another at the apex, the latter surrounded by the narrow 
black margin; pygidium yellow, with a black central band ; underside black, a spot above the anterior 
coxe, another at the sides of the last ventral segment, and the prosternum flavous; legs black, the 
entire under surface of the femora yellow. 
Hab. Mexico, Ventanas in Durango (Hége). <A single specimen. 
In this brightly-marked species the elytra have well-defined yellow spots, the posterior 
spots being divided by the black punctures of the striae. These spots are placed as in 
C. plagiatus and several other species, but are fewer in number ; the elytral punctuation 
is much stronger and deeper than in the allied forms, it being well visible to the naked 
eye. 
55. Cryptocephalus multipunctatus. (Tab. XXXVII. fig. 22.) 
Fulvous ; the head and thorax finely and closely rugose-punctate; elytra deeply, closely, and regularly 
punctured, all the interstices strongly costate. 
Length 2 lines. 
Q. Head closely punctured at the vertex ; antennz entirely fulvous, the apical joints slightly darker ; thorax 
quite twice as broad as long, fulvous, narrowly margined with piceous, the surface closely and finely 
rugose, the interspaces finely punctured ; elytra each with ten closely-approached rows of deep punctures 
divided only by narrow cost, the cost still more strongly raised at the apex, and here and there 
connected by transverse wrinkles. 
Hab. Mexico, La Parada (Sailé). 
This Cryptocephalus is entirely falvous in colour and only represented by a single 
female specimen. The sculpture of the elytra is, however, very different from that of 
any other species of our region: all the punctures are extremely closely placed, the rows 
divided by strongly raised coste, of which the sixth and seventh are joined at a little 
distance from the apex, and connected behind by a short stem or branch with one 
of the preceding and one of the following rows, which are also posteriorly united and 
form a ridge parallel to the apical margin; the punctures and coste are nowhere inter-
