tooth, at base as wide or wider than at apex (plate V, fig. 7) ; 
prothorax coarsely rugose, lateral tubercles rather indistinct; 
median line absent or very faint diversa n. sp. 
9. Hind femora narrower at base than at apex and moderately 
strongly incrassate towards the sub-apical tooth; prothorax 
shining and densely rugose, not alutaceous; inter\'als of 
elytra more or less densely punctate fidvipes Lac. 
Hind femora moderately robust, at base as wide or wider than at 
apex and gradually widening to the sub-apical tooth (plate V, 
fig. 8) ; intervals of elytra scarcely punctate; prothorax gener- 
ally alutaceous and feebly shining, surface punctate or 
punctate-rugose, the punctures relatively shallower than 
usual, when densely punctate there is generally a space on 
each side near median line more sparsely punctate, showing 
the alutaceous sculpture gennari IVIann. 
ID. Side pieces of presternum finely rugose, at least in anterior 
half, posteriorly more or less distinctly finely strigate-rugose . 11. 
Side pieces of prostemum relatively coarsely strigate, at least 
posteriorly, anteriorly often strigate-rugose but then never 
finely 13. 
11. Prothorax punctate, punctures rather fine, sometimes a few 
larger punctures intermixed, occasionally partly rugose 
through confluence of punctures but never entirely rugose; 
form more convex and without elytral indentations metalUca Ahr. 
Prothorax distinctly rugose with at most only a few punctures 
on the disk; form less convex and with more or less distinct 
elytral indentations 12. 
12. Lateral margin of elytra from a postero-lateral view generally 
evenly acute from base to apex; form shorter with usually 
moderately deeply impressed elytral indentations; antennae 
rather stout, second and third joints small, equal or subequal, 
outer joints stouter pusilla Say. 
Lateral margin of elytra acute at most in not quite basal half 
and then more or less distinctly interrupted; form elongate; 
elytral indentations more feebly impressed ; antennae elongate, 
third joint longer than second, outer joints slender wallisi n. sp. 
13. Elytra without transverse, coarse rugae, intervals vermiculate- 
rugose; prothorax finely rugulose with moderately large 
punctures vermictilata n. sp. 
Elytra with more or less distinct coarse rugae, intervals punc- 
tate not vermiculate-rugose 14. 
14. Prothorax apparently longer than usual, very finely rugose or 
very finely strigate-rugose, with or without moderately large 
punctures; lateral tubercle rather elongate; antennal joints 
four to eleven elongate longicollis n. sp. 
Prothorax as usual, rather short and less finely strigate-rugose, 
with large or small punctures; lateral tubercles not elongate; 
antennal joints shorter and nearly as in pusilla 15.
