mew names, including a new name that I propose for an insect 
previously described as a ‘“‘ var. (?)”—and furnish a tabulation 
of the characters of the 32 species thus regarded as recognisable 
members of the genus. As it seems undesirable to altogether 
leave out the 15 species that are not satisfactorily described, I 
have drawn up a supplementary tabulation of them founded upon 
-such characters as their authors have mentioned, which will, 
perhaps, assist in their identification. I have been unable in the 
case of one of them [Z. (Z’mesidera) rubricollis, H ope], however, 
to place it even in the supplementary tabulation owing to there 
being no precise description of either the structure of its antenne 
-or the sculpture of its elytra. 
A. Joint 2 of antennz not notably shorter than 3 (see note in the descrip- 
tion of Z. Cowleyi, Blackb.). 
B. Elytra not of uniform metallic colouring. 
C. Head not black. 
D. Base (at least) of elytra testaceous. 
K. Legs unicolorous, or nearly so.

GG. Elytra entirely testaceous ... dichroa, Germ. 
FF. Scutellum testaceous. 
G. Head of short triangular form... tenwicornis, Fairm, 
GG. Head more elongate. 
H. EKyes almost contiguous... Cowleyi, Blackb.

each other . btutea, Macl.

F, Elytra with black markings. 
G. Elytra very closely punctulate mnigro apicata, Fairm. 
GG. Elytra sparsely punctulate ... nigroplagiata, Fairm. 
FF. Elytra devoid of black markings. 
G. Elytra much less closely punc- 
tured near base than behind = ¢ricolor, Le Guill. 
GG. Elytra uniformly punctured.

punctured (size about 51.)  padllicolor, Fairm.

D. Prothorax black ... splendida, Fairm. 
DD. Prothorax testaceous or rufo-tes- 
taceous Be: ... brevicornis, Blackb. 
CC. Head extremely elongate ee gloriosa, Blackb. 
AA. Joint 2 of antenne notably shorter than Z,

miculate-rugulose.
