202 PHYTOPHAGA.—SUPPLEMENT. 
elytra (the base of which is depressed), in connection with the fulvous antenne and 
legs, distinguish 1. obliterata from its allies. The female varies in regard to the 
colour of the legs and is more strongly punctured; but is not distinguished by strongly 
marked elytral coste, the interstices being only slightly convex at the sides. | 
A somewhat doubtful species. 
30. Noda ovata. 
Ovate, obscure eneous, the antenne and legs fulvous ; thorax transverse, the sides rounded, the surface finely 
and closely punctured ; elytra more or less widened at the middle, the apex pointed, the disc very closely 
punctate-striate. 
Q. Elytra more elongate, less widened, the rows of punctures separated by narrow smooth longitudinal 
spaces, the sides with about six tubercles, which are placed longitudinally in two rows. 
Length 14-2 lines. 
Hab. Panama, Pefia Blanca, Tolé (Champion). 
NV. ovata may be at once separated from its allies by its ovate, posteriorly pointed 
shape, the dull brownish-eneous colour, the fulvous antenne and legs, the transversely 
shaped thorax (the sides of which are rounded), and the very closely punctured elytra. 
The head is somewhat remotely punctured ; the labrum and the robust mandibles are 
fulvous ; the antenne barely extend to the middle of the elytra, and are rather stout ; 
the thorax is scarcely narrowed anteriorly, and its anterior angles are subtuberculiform 
and furnished each with a single hair; the elytra have the shoulders rounded (scarcely 
prominent), and are devoid of any post-basal depression. The female differs considerably 
from the male in the sculpture of the elytra ; and has, in addition to the six more or 
less elongate tubercles at the sides, a strongly raised costa placed parallel with the 
lateral margin, all the other interstices being also more or less convex. 
It is possible that WV. ovata may be better placed in Lefévre’s genus Hphyrwa (Ann. 
Soc. Ent. Fr. 1889, p. 832), the thorax being very strongly transverse. Many species 
of Noda, however, vary greatly in the form of the thorax (and also in having more or 
less filiform antenne), and this seems to me to be an inconstant character. 
31. Noda bella. 
Greenish-black; above metallic yellowish-green, golden-yellow, or pale cupreous; the base of the antenne 
fulvous ; thorax transversely convex, very closely punctured ; elytra very closely geminate-punctate-striate. 
_Q. Larger, more pointed posteriorly, the legs fulvous. 
Length 13-2 lines. 
Hab. Mexico, Juquila (Sallé, Flohr). 
Of rather convex, subcylindrical, and somewhat posteriorly narrowed shape, and 
bright golden-yellow or yellowish-green colour; the head, thorax, and elytra very 
closely but not very finely punctured ; the elytra with an obsolete depression below the 
shoulders, the punctuation arranged in closely approached double rows which towards 
the apex become single (as is generally the case in this genus), and the interstices
