NODA. 197 
less transverse and less rounded at the sides, the elytral punctuation somewhat finer 
and more remotely placed, and the upper surface of a more decided dark blue colour. 
Mr. Flohr has kindly sent me examples of both sexes. ‘The female was hitherto 
unknown to me; it differs from the male in the costate lateral interstices of the elytra, 
and in its more pointed shape and rather stronger punctuation. 
14 (a). Noda fulvicornis. 
Subcylindrical, convex, eneous, dark metallic blue or greenish-blue; the antenne and legs fulvous; thorax 
transversely convex, very finely and closely punctured ; elytra rather closely punctate-striate, the punc- 
tures coarser than those of the thorax. 
Length 1 line. 
Of rather parallel, convex, and cylindrical shape; the head finely but irregularly punctured (but variable in 
this respect) ; labrum and palpi fulvous, the last joint of the latter comparatively robust ; antenne entirely 
fulvous, or with the terminal joints slightly darker; thorax transverse, still more convex than in the 
allied forms, the sides rounded, the surface very closely and finely punctured; scutellum slightly broader 
than long, its sides rounded; elytra parallel, rather regularly punctate-striate, the punctures gradually 
becoming finer towards the apex and arranged in close and slightly geminate rows; legs fulvous, robust, 
the femora in some specimens darker. 
Hab. Mexico, Oaxaca, Cordova, Capulalpam (Sal/é). 
Very closely allied to WV. balyi, but differing in the dark blue colour of the upper 
surface; the thorax is also longer, less rounded at the sides, more narrowed in front, 
and more finely and more closely punctured (the punctures equal in size, this not 
being the case in NW. balyi). N. balyi is also larger, and of an eneous or obscure 
cupreous colour. 
Noda curtula (p. 120). 
To the Mexican localities given, add :—Presidio, Tres Marias Is. (Forrer), Amula, 
Chilpancingo, and Tepetlapa, all in Guerrero (H. H. Smith), Tacambaro in Michoacan, 
Matamoros Izucar in Puebla (Hoge). 
Numerous examples since received from the above localities prove that N. curtula, 
like so many of its congeners, is a very variable species, not only in colour but in 
shape, some specimens being broadly ovate, others more oblong and less rounded ; the 
punctuation of the elytra is close and distinct (but often very fine near the suture), that 
of the female much coarser, the interstices at the sides in this sex being costate; the 
thorax is very finely punctured on the disc, extremely closely so at the sides. 
N. curtula somewhat resembles Chrysodina cupriceps in shape, but, in my opinion, 
is better placed in Noda. 
18 (a). Noda basalis. 
Broadly ovate, dark brownish-eneous, the basal joints of the antenne fulvous; thorax finely and closely 
punctured at the sides, more remotely so on the disc; elytra irregularly geminate-punctate-striate, and 
laterally with three or four short costz at the base. 
Length 2 lines.
