86 PHYTOPHAGA.—-SUPPLEMENT. 
Urodera hopfneri (p. 35). 
According to Lacordaire the thorax of U. hépfneri is scarcely wider than long: 
specimens with the thorax thus formed I have not seen, although nearly a hundred 
from different localities in Mexico are before me. The Guatemalan examples in 
Sallé’s collection labelled U. hépfneri I am unable to distinguish from U. crucifera. 
Urodera chevrolati (p. 35). 
To the locality Mexico, add:—Pinos Altos in Chihuahua (Buchan-Hepburn), 
Ventanas in Durango (Hége), Almolonga (Flohr), Oaxaca, Cordova, Vera Cruz, Etla 
(Sallé). 
The specimens I provisionally refer to this species have the thorax more transversely 
shaped than in U. crucifera, and the elytra fulvous, with a narrow oblique transverse 
black band placed at the middle (this band being generally twice as wide as it is in 
the examples I identify with U. crucifera); but the elytra are sometimes entirely 
fulvous, or have each a small black lateral spot placed before the middle. 
5. Urodera dilaticollis. 
Black; thorax much broader than long, with flattened sides, impunctate; elytra fulvous, finely punctate- 
striate, a central transverse band (angulate at the sides), and the margins narrowly, black. 
Var, Elytra with a small black anterior spot. 
Length 23-3 lines. 
Somewhat widened posteriorly ; the head very shining and impunctate, with the exception of a few punctures 
near the inner margin of the eyes ; antenne with the third joint fulvous, the other joints black; thorax 
strongly transverse, the sides flattened and rounded, the median lobe moderately produced, the surface 
very shining and impunctate; scutellum rather broader than long; elytra narrowed at the base, 
extremely finely punctate-striate, fulvous, narrowly margined with black, and with a narrow transverse 
black band at the middle, this band widened at the suture and laterally angulate. 
Hab. Mexico, Santa Clara in Chihuahua, Refugio in Durango (Hége). 
Five specimens. U. dilaticollis might at first sight easily be mistaken for U. cruci- 
Sera or U. chevrolati; but it differs very considerably from both in the shape of the 
thorax and elytra. The thorax in the present insect is very shining and smooth, 
without trace of punctures, and only the flattened sides show the usual fine rugosities ; 
it has the sides rounded and flattened to a much greater degree than in any of our 
numerous examples of the two above-named allied species ; in these latter its sides do 
not project beyond the elytra. ‘The elytra are distinctly narrowed at the base, giving a 
posteriorly widened shape to the insect (in opposition to the more narrowed appearance 
of U. crucifera) ; and the band, instead of being straight as in U. crucéfera, is angulate 
at the sides. In the variety, which was obtained at Refugio, the elytral band is 
replaced by a small black spot; but the structure of the thorax and of the elytra agrees 
exactly with that of the typical form. Babia undabunda, Lac., seems to agree in the 
markings of the elytra with U. dilaticollis; but Lacordaire does not mention the shape 
of the thorax in that species, which, moreover, inhabits Brazil.
