198 PHYTOPHAGA.—SUPPLEMENT. 
¢. Head moderately closely and finely punctured, with an obsolete depression between the eyes, the latter 
sinuate at the inner margin; epistome not separated from the face, a little more strongly punctured than 
the head; labrum piceous; antenne scarcely extending to the middle of the elytra, the lower eight joints 
fulvous, the terminal ones nearly black, the latter thickened ; thorax strongly transverse, but moderately 
‘narrowed anteriorly, the sides very little rounded, the anterior angles produced into a short straight 
point, the surface very finely and closely punctured at the sides, more remotely so on the disc; scutellum 
much broader than long, impunctate ; elytra broadly ovate, scarcely narrowed posteriorly, with a short 
depression below the base, the punctuation fine and arranged in irregular double rows, which are inter- 
rupted near the shoulders and at the sides by four or five short coste (these extending as far as the basal 
depression, the outer one, however, accompanying the lateral margin throughout), the apical portion im- 
pressed near the suture with a deep stria, the extreme apex rather pointed ; the tibiee are generally more 
or less fulvous at the apex; the prosternum is distinctly longer than broad and constricted at the middle, 
Hab. Mexico, Ventanas in Durango, Presidio (forrer). 
Like WV. curtula, the present species is broadly ovate (instead of having the more 
oblong shape of a typical Noda); it agrees, however, with Moda in the form of the 
antenne, scutellum, and prosternum. WW. basalis, of which apparently only female 
specimens were obtained, may be distinguished from NV. curtula by the short longitu- 
dinal coste at the base of the elytra and by the less crowded punctuation at the sides 
of the thorax. 
22. Noda placida. 
Metallic greenish-blue, the basal joints of the antenne and the legs fulvous; thorax short, extremely finely 
and rather remotely punctured; elytra with a shallow transverse basal depression, closely and rather 
strongly punctate-striate. 
@. Above brownish-cupreous ; elytra with a deeper basal depression, and with three or four longitudinal 
cost at the sides. 
Length 14-13 line. 
Hab. Mextco, Cordova, Jacale (Sallé), Zacnaltipan in Hidalgo (Hoge) ; PANAMA, 
Volcan de Chiriqui (Champion). 
Of this species a male and a female specimen from Cordova (taken “in copula ”), as 
well as two others from Jacale, are contained in the Sallé collection. NH. placida seems 
to me to differ from most other species from our region in the well-marked basal 
depression of the elytra in connection with the very fine punctuation of the thorax, 
the closely-punctured elytra, and the fulvous legs. In the female the elytral depression 
is deeper, but the punctuation is much finer and somewhat arranged in double rows. 
In the male the thorax is short, strongly transverse, and rather strongly rounded at the 
sides, the anterior angles being produced into a short outwardly-directed point. 
The specimens from Zacualtipan agree entirely with the others, as well as those 
obtained by Mr. Champion in Chiriqui. 
23. Noda metallica. 
Pale metallic green; antenna black; the basal five joints fulvous; thorax strongly transverse, finely and 
rather closely punctured ; elytra finely subgeminate-punctate-striate ; legs obscure cupreous.
