sculpture of the thorax, and from the latter in the much 
smaller submarginal foveae on the elytra. The polished 
spaces on the disc of the thorax are large and irregularly 
shaped, much as in C. rufopiceus and C. punctipennis, Gorh. 
[Cymbolus quadrituberculatus, n. sp. 
Moderately elongate, depressed, shining; above brown, the 
thorax piceous on the disc and rufescent in front, beneath obscure 
ferruginous, the antennae, mouth-parts, and legs testaceous, the 
eyes black; thickly clothed with very long, erect, pale brownish 
hairs, the legs also villose, the under surface sparsely pubescent. 
Head short, irregularly punctate; eyes large, coarsely facetted ; 
antennae serrate from the fourth joint (8-11 are missing). Thorax 
short, rounded at the sides, slightly narrowed in front, the base 
sinuate near the obtuse hind angles, the margins crenulate; the 
surface densely, confluently, umbilicate-punctate, the disc with 
several small, scattered, polished, tuberculiform callosities, four of 
which (quadrangularly placed) are more prominent than the rest. 
Elytra moderately elongate, depressed, very little wider than the 
thorax, subparallel to beyond the middle; coarsely, closely, con- 
fusedly punctate, and with a row of larger foveiform impressions 
along the submarginal ridge, the latter placed extremely close to 
the crenulate outer margin. Beneath finely punctate. 
Length 43, breadth 2 mm. 
Hab. Brazit, Rio de Janeiro (Fry, in Mus. Brit.). 
One specimen. This insect unquestionably belongs to 
Cymbolus; it differs from the northern forms in having 
four small polished tuberculiform prominences on the disc 
of the thorax and the submarginal ridge of the elytra 
placed extremely close to the marginal carina. | 
EUCYMBOLUS, n. gen. 
Eyes transverse, sinuato-emarginate in front, finely facetted ; 
elytra with a very sharp submarginal carina, corresponding in length 
with the deeply excavate epipleuron, the latter becoming very broad 
anteriorly and narrow behind, and about reaching the second 
ventral suture; metasternum short; ventral segments 3-5 much 
shorter than those preceding; body broad-ovate, convex, metallic, 
strongly villose; the other characters as in Cymbolus. 
Type, E. cyaneus. 
The single species referred to this genus has the general 
structure of Cymbolus—serrate antennae, securiform apical
