496 Mr. J. SBaly’s Descriptions of 
transversely on either side. Elytra broader than the 
thorax, parallel, angulate-rotundate at the apex, convex, 
deeply excavated below the basilar space, the latter 
thickened ; coarsely ,and closely punctured, rugulose on 
the anterior disk; on the basilar space and again at the 
extreme apex are several ill-defined longitudinal coste ; 
near the lateral margin are two others more strongly 
raised and entire. 
Metaxyonycha octosignata. 
Elongata, parallela, convexa, flavo-fulva, nitida, 
thorace vage punctato, lateribus rotundatis, integris ; 
elytris confuse punctatis, ad apicem elevato-costatis ; 
utrinque maculis quatuor, duabus ad basin, duabusque 
pone medium, nigro-purpureis. Long. 4 lin. 
Hab. Amazons; a single specimen collected by Mr. 
Bates. 
Face deeply impressed transversely between the eyes, 
vertex and front stained with piceous, sparimgly punc- 
tured; anterior margin of clypeus bidentate; eyes large, 
subrotundate, slightly emarginate, black; antenne equal: 
to the body in length, entirely fulvous. Thorax nearly 
two-thirds as broad again as long; sides regularly 
rounded, entire, disk sparingly punctured. Elytra broader 
than the thorax, their sides parallel, their apices con- 
jointly angulate-rotundate; above convex, subrugulose 
below the basilar space, rather closely punctured, the 
punctures arranged without order over the general 
surface, placed in a single row next the suture, and 
arranged irregularly in longitudinal striez near the apex, 
the interspaces between these strie elevate-costate; 
on the basilar space are also several nearly obsolete 
coste. The four spots on each elytron are arranged as 
follows :—two immediately below the base, parallel; one 
covering the humeral callus, narrow, the other near 
the suture, narrowly oblong; two below the middle, 
the inner one subquadrate, placed closely to the suture, 
the outer one situated on the middle of the outer 
disk, linear-elongate, its apical end parallel with the 
upper margin of the inner spot, its lower end extending 
downwards towards the apex of the elytra.
