G Elytral apices very broadly rounded. 
H Pronotum with the transverse basal impression continuous, 
though feeble across the median line; elytra subopaque, 
closely finely punctate, (6) quadrata Lee. 
HH Pronotum with the basal transverse impression not con- 
tinuous across the median line; elytra shining, rather 
sparsely moderately punctate. (7) knulli n. sp. 
GG Elytral apices narrowly rounded. 
H Pronotum usually as long as wide, the pubescence long and 
distinct. (8) instabilis Hald. 
HH Pronotum distinctly wider than long, the pubescence short 
and stout; the disk in some cases impressed on the sides. 
(9) flaviventris Schaeffer. 
FF Pronotum with basal transverse impression feeble; elytra with 
scutellar and humeral lobes equally prominent; scutellum emar- 
ginate at apex; the form more elongate; the sides of the elytra 
nearly parallel. (10) sexmaculata Linn. 
DD Elytra distinctly truncate at tip, with apices acute on the sutural and

(Stenostrophia Csy.). 
E Vestiture of body in general bright yellow and rather long. 
F Vestiture of black areas on pronotum and elytra brown or black; 
pronotum distinctly granulate-punctate, the punctures of median 
size, deep, granulate and usually very closely placed. 
(11) tribalteata Lee. 
FF Vestiture of entire dorsal surface yellow; disk of pronotum smooth, 
punctures small and not closely placed. (12) coquUletti Linell. 
EE Vestiture of the body dark or pale brown and rather short. 
(13) amabilis Lee. 
CC Pronotum with the sides rounded or sinuate at the middle, not angulate; the 
transverse basal impression not continuous across the dorsum, interrupted 
by an extension of the disk at the middle. 
D Elytra nearly twice as wide as pronotum at the base; basal transverse 
impression of pronotum feebly evident on the sides at the base; colour 
black; pubescence sparse, and distinct; pronotal punctures dense and 
moderate in size; elytral punctures a little smaller and sparser than on 
the pronotum; scutellum emarginate at apex. (14) barbari Fall. 
DD Elytra but little wider than pronotum at the base; pronotum with trans- 
verse basal impression deep towards the sides. 
E Elytra with basal margin and cephalic half of lateral margin strongly 
sinuate, shape distinctly cuneiform; size much larger, length 9 to 
12 mm. (15) cordifera Oliv. 
EE Elytra with basal and lateral margins at most only feebly sinuate; 
smaller species, length less than 9 mm. (except impura). 
F Elytra ferruginous with distinctly defined black spots; metaster- 
num of males with two carinse terminating caudad in a tooth. 
G Elytra with basal black spots not impressed, elongate and 
widely separated from the suture; with a subapical black 
spot. (16) sexspiiota Lee. 
GG Elytra with basal black spots concave, rounded, adjacent to 
the suture; with apical fifth black. (17) isabdlae Hop.
