side before the eyes, as well as down the middle, the eyes convex ; antenne stout, the scape widened 
from near the base, joint 2 of the funiculus a little longer than 1. Prothorax as long as broad, rounded 
at the sides anteriorly and constricted in front, densely, finely punctate; with a deep arcuate transverse 
groove behind the middle and an oblong excavation on the dise towards the apex, in each of which is an 
oblong polished shining fovea, and various other large, confluent, irregular, foveiform depressions. 
Scutellum well developed, convex. Elytra not wider than the prothorax, elongate, subparallel from the 
obliquely rounded humeri to about the middle, transversely depressed at the base and conjointly 
produced at the apex; with rows of coarse punctures placed along extremely fine geminate strie, the 
interstices uneven, densely, finely punctate, 3, 5, 7, and 9 widened and costate, 3, 7, and 9 partly bare. 
Legs very stout; anterior tibie strongly bowed. 
Length 113-14, breadth 3-34 millim. (<¢ ?) 
Hab. Guatemata, San Gerénimo in Baja Vera Paz (Champion). 
Two specimens. A remarkably distinct form, easily separable from the following 
by the sharply albo-lineate fifth elytral interstice, the prominent scutellum, and the 
very coarsely wrinkled, foveolate prothorax, the two cblong, bare, polished fovee on 
which form an interrupted median sulcus. 
2. Mazenes geminatus, sp.n. (Tab. XIII. fig. 5, ¢.) 
Elongate, narrow, piceous; above densely clothed with brown scales, with green and ochreous scales 
intermixed, the latter mainly confined to the foveiform depressions, the under surface uniformly viridi- 
squamose, the surface also set with stiff decumbent sete similar to those on the legs. Head and rostrum 
densely, finely punctate, the oblique ridges on the rostrum broad and not very conspicuous; antennal 
scape subclavate at the tip; eyes feebly convex. Prothorax a little longer than broad, cylindrical, 
narrowed and feebly constricted in front, densely, finely punctate; transversely wrinkled and irregularly 
foveolate, the disc with two longitudinally placed, small, polished fovese. Scutellum very small. Elytra 
elongate, very little wider than the prothorax, subparallel in their basal third, transversely depressed at 
the base, the humeri oblique, subangular; with rows of moderately coarse punctures placed along 
extremely fine geminate stria, the interstices uneven, densely, finely punctate, 3, 5, 7, and 9 widened 
and more or less raised, the outer striz coalescent from a little below the base. Legs stout. 
Length 144, breadth 3? millim. (<.) 
Hab. Guatemata, Purula in Vera Paz (Champion). 
One specimen. More cylindrical than M. difoveatus, the antennal scape more 
slender, the excavations on the prothorax much shallower, the scutellum smaller, the 
elytra at the base a little broader than the prothorax, and with the alternate interstices 
wider and less raised, the under surface uniformly clothed with pale green scales. 
It is probable that the green scales are partly abraded on the upper surface. 
3. Mazenes lineatus, sp. n. (Tab. XIII. fig. 6, 2.) 
Elongate, widened posteriorly, piceous ; thickly clothed with brown, pale ochreous, and whitish scales—the 
ochreous scales on the elytra condensed into lines on the depressed portions of the surface and those on 
the prothorax placed in the transverse furrows, the white scales on the elytra condensed into a faint 
stripe on the fifth interstice and an angular patch near the apex; the scales on the under surface and 
legs cinereous or whitish, with brown scales intermixed ; the apex of the elytra and the under surface also 
set with bristly decumbent sete, similar to those on the legs. Head and rostrum densely, finely punctate, 
the rostrum deeply excavate down tiie middle between the broad oblique ridges and also hollowed on 
each side before the eyes, the latter moderately convex; antennal scape gradually widened outwards,
