194 PHYTOPHAGA.—SUPPLEMENT. 
| 4 (a). Noda imitans. 
Oblong-ovate, narrowed posteriorly, eneous, the base of the antenne fulvous ; thorax very closely punctured ; 
elytra closely and strongly geminate-punctate-striate, the interstices minutely punctured and slightly 
costate at the sides. 
Length 12 line. 
Q. Head irregularly but rather closely punctured, the labrum and palpi piceous; antennae short, scarcely 
extending beyond the base of the thorax, the basal and the five terminal joints piceous, the others fulvous ; 
thorax rather more than twice as broad as long, the sides very slightly rounded, the anterior angles acute, 
the surface closely and distinctly punctured, the sides more closely than the disc ; elytra with deep and 
closely-placed double rows of punctures, the interstices convex at the sides ; underside and legs seneous, 
the underside finely granulate and punctured. 
Hab. Mexico, Durango city (Hége). 
In the strongly and closely geminate-punctate-striate elytra this insect resembles 
N. lateralis, from which it differs, however, in having the lateral interstices only 
slightly raised (these in W. lateralis being replaced by highly raised ridges). A 
single male specimen, also obtained at Durango, agrees in colour with the females _ 
from which our description is taken, and may be the other sex of the same species; it 
has the thorax more convex and more strongly rounded at the sides; the elytra, 
however, are quite differently punctured, the punctuation being fine and arranged in 
closely approached single rows. The general colour may be described as obscure 
cupreous or bronze. 
Noda lefevrei (p. 117). 
To the localities given, add :—Mexico, Vera Cruz, Orizaba (Sallé), Atoyac, Teapa 
and Frontera in Tabasco (H. H. Smith); Guatemata, Sabo, Tamahu, El Jicaro, Purula, 
and San Gerénimo, all in Vera Paz (Champion), Aceytuno (Salvin). 
N. lefevrei is evidently subject, like most of its congeners, to great variation ; and I 
refer all the specimens which show distinctly raised or costate elytral interstices at the 
apex, and which have the extremities of the tibie more or less fulvous, to this species. 
In the Sallé collection, WV. lefevret bears the name of NV. apicecostatis. 
The present insect cannot be mistaken for WN. lateralis, Jac., which has also the 
elytra costate at the apex, owing to the thorax being rounded at the sides (in WV. late- 
ralis the sides are nearly straight). In both sexes of WV. lefevrei the elytra are without 
tubercles, the female thus differing from that of NV. lateralis. 
Mr. Smith obtained numerous specimens at Teapa. 
9 (a). Noda opacicollis. 
neous or metallic blue, the antenne (the first and the apical joints excepted) and the tibie: fulvous; thorax 
opaque, finely punctured; elytra rather finely subgeminate-punctate-striate, the interstices costate at 
the apex. 
Length 13-1? line. 
Hab. Mexico, Tapachula in Chiapas, Teapa in Tabasco (Hége).
