196 PHYTOPHAGA.—SUPPLEMENT. 
9 (c). Noda sinuata. 
Greenish-black, above dark blue or obscure cupreous, the basal joints of the antenne fulvous; thorax finely 
punctured, the posterior angles acute; elytra finely punctate-striate ; legs greenish-zeneous. 
Length 14 line. . 
Head minutely granulate, rather strongly and closely punctured, a triangular space above the insertion of the 
antenne shining and smooth; mandibles and the terminal joints of the palpi piceous; antenne nearly 
two-thirds the length of the body, the basal two or more joints (sometimes as many as the basal six) 
fulvous (the first stained with piceous above), the rest black; thorax transverse, more than twice as 
broad as long, the anterior margin perfectly straight, the posterior margin produced at the middle, the sides 
rounded, concave near the base, the posterior angles pointed and produced, the surface finely, irregularly, 
and not very closely punctured, the interspaces minutely granulate; scutellum smooth; elytra convex, 
without basal depression, rather evenly and finely punctate-striate, the punctures distinct to the apex and 
stronger at the sides than on the disc, the interstices flat ; underside and legs greenish-seneous. 
Hab. Mexico, Chilpancingo in Guerrero, Huetamo in Michoacan (f6ge). 
Closely allied to, but apparently distinct from, WV. chontalensis, from which it chiefly 
differs in having the sides of the thorax sinuate or concave near the base (instead of 
simply rounded) and the posterior angles acutely pointed, and the head more strongly 
punctured. The antenne are comparatively elongate; the colour of the basal joints 
is variable. The female only differs from the male in the stronger elytral punctuation 
and in the raised submarginal interstices. 
9(p). Noda elongata. 
Elongate, subcylindrical, blackish-zeneous, above dark blue (3) or violaceous (9); antenne and legs fulvous ; 
elytra strongly and closely punctate-striate, with a slight transverse depression below the base. 
$. Thorax remotely and finely punctured. 
@. Thorax more transverse, more closely punctured ; the elytra broader, the lateral interstices obsoletely 
costate. 
Length 13-14 line. 
3. Of unusually elongate shape, metallic dark blue above; the head without central groove, rather irregularly 
but distinctly punctured; the labrum, palpi, and antenne fulvous, the terminal joints of the latter 
slightly darker; thorax about twice as broad as long, the sides evenly rounded and moderately narrowed 
in front, the anterior angles not produced, the surface finely, very remotely, and irregularly punctured ; 
scutellum slightly broader than long; elytra convex and nearly parallel, scarcely perceptibly depressed 
below the base, the punctures strong and arranged in close rows, the submarginal row very regular and 
even; legs fulvous. 
Hab. Mexico (Sallé). 
There are two specimens of this insect, marked ¢ and 9, and named W. inconstans, 
in the Sallé collection. The fulvous antenne, less transverse and more remotely punc- 
tured thorax, the entirely fulvous legs, and more elongate general shape (especially of 
the male) separate NV. elongata from N. chontalensis. In the female of the present 
species the elytral depression is a little more distinct than in the other sex. 
Noda violaceipennis (p. 118). 
To the localities given, add :—Mextco, Oaxaca (Sallé), Juquila (Flohr). 
Mexican specimens differ from those from Guatemala in having the thorax rather
