Key to the Species 
A Antenna black (except sometimes annulate in balteatm), with segments 6 to 11 
bearing impressed poriferous areas. 
B Pronotum clothed with abundant, long, erect hairs, with or without recumbent 
golden pubescence; elytral apices obliquely truncate-acuminate. 
C Pronotum densely clothed with recumbent golden pubescence beneath long, 
erect hairs; punctation of pronotal disk dense with fine and coarse punc- 
tures intermixed; elytral apices very strongly acuminate. 
(1) acuticauda Csy. 
CC Pronotum with recumbent golden pubescence only at apical and basal mar- 
gins; punctation uniformly coarse and deep. 
D Pronotum only moderately widened behind, inflated before the middle, 
disk rather closely punctured, with recumbent yellow pubescence dense 
at base, apex, and on the sides beneath; elytra moderately cuneiform, 
feebly shining, closely punctured, with apices obliquely truncate. 
(2) zebratus Oliv. 
DD Pronotum very strongly regularly widened from apex to base, moderately 
constricted at the apex, not inflated in front, disk very coarsely sparsely 
punctured, with recumbent yellow pubescence dense at base and apex 
only; elytra very strongly cuneiform, shining, punctures small and 
rather widely separated, apices very strongly oblique, acuminate, 
slightly emarginate. (3) badim Newm. 
BB Pronotal disk clothed with recumbent or semi-recumbent pubescence, without 
long erect hairs intermixed. 
C Vestiture of pronotum dark or nearly black, with or without apical and basal 
margins of golden pubescence. 
D Pubescence of pronotum and elytra pieeous to black, without golden mar- 
gins on the former; punctation of pronotum fine and moderately close, 
that of elytra fine and dense, (4) lugubris Say. 
DD Pronotum margined with golden pubescence at apex and base, coarsely 
punctured. 
E Pronotum rather closely punctured; elytra with small punctures, 
black with two large, basal, reddish-yellow patches on each, in many 
cases more or less completely fused, humeri black or with a small 
pleural spot, apical half black, rarely with a small postmedian and 
an apical spot; legs black; apex of female pygidium feebly, broadly 
emarginate. (5) lunatus Fab. 
EE Pronotum sparsely punetured; elytra with coarse punctures towards 
the base, black with four, narrow, transverse, yellow bands, the basal 
of these incomplete, 2nd and 3rd in many cases more or less com- 
pletely fused at the suture; legs rufous or bicoloured; apex of female 
pygidium narrowly, deeply emarginate. (6) sparsus Lee. 
CC Vestiture of pronotum golden throughout, with denser band at basal and 
apical margins. 
D Pronotum with sides subparallel on basal three-fourths, abruptly narrowed 
in front, disk with moderate to coarse dilated punctures; elytra with 
apices obliquely truncate. 
E Pronotum not inflated in front, disk densely, coarsely, rugosely punctate, 
pubescence stout and recumbent, conspicuous; antennas slender; 
elytra yellow with three narrow, black, transverse bands, apices in 
some cases black; punctation very shallow, apices strongly truncate, 
outer angle acute. (7) batleatus Horn. 
EE Pronotum inflated in front, disk moderately not very closely punctate, 
interstices distinct, pubescence fine and erect; antennse notably 
stout; elytra black with four transverse yellow bands; punctation 
rather deep, apices feebly truncate, outer angle rounded. 
(8) brunnicomis Lee. 
DD Pronotum very much widened behind, disk with smaJl, subgranulate 
punctures; elytra with apices emarginate. 
E Elytra reddish brown or black, with transverse yellow bands and the 
pubescence of the dark areas nearly black, very finely and closely 
punctured; pronotum with sides regularly converging, hardly inflated 
in front.
