382 HETEROMERA. 
The two specimens captured by Herr Hége at Villa Lerdo are apparently immature ; 
they have the elytral punctuation very indistinct. 
‘Distinguished from G. minimum by the much smoother thorax and elytra; the 
colour above and beneath is testaceous.

This genus contains upwards of one hundred described species, very few of which 
are from the New World. Six species have been recorded from the United States 
and six from Mexico, but not one from the South-American continent *, Four are 
here added from Mexico or Central America. In Z%. nigromaculata and some other 
species of this genus the outer lobe of the maxille is furnished with several coarse 
spiny sete. Z. nigromaculata and Z. fulva approach the Australian genus Palestra in 
the form of the antenne. Our species may be tabulated thus :—

1. Zonitis flohri. (Tab. XVII. fig. 18.) 
Zonitis flohri, Dugés, An. Mus. Michoacano, ii. p. 110 dis’. 
Hab. Mexico (coll. F. Bates), Vera Cruz (Flohr 1), Orizaba (Sallé), Jalapa (Hage). 
Found in abundance by Herr Hége at Jalapa. Dugés’ description ' appears to have 
been made from a greasy or discoloured specimen.. This insect much resembles the 
var. 3 of Nemognatha ceruleipennis, Perty, but it has the elytra dull instead of shining. 
The head (the eyes excepted), thorax, and under surface, the femora, and the base of 
the tibice are flavo-testaceous, the rest of the legs and the antenne piceous or black ; 
the elytra are metallic blue or violaceous (more obscure in greasy examples), opaque. 
The head is triangular, broad, short; the thorax is strongly transverse, narrowed and 
broadly rounded at the sides anteriorly, and has a deep transverse depression on either 
side in front and a deep median groove behind, the surface with fine, widely scattered 
punctures; the elytra are very densely, confluently, finely punctured, with the inter- 
spaces somewhat granular; the under surface is closely and finely punctured. In the 
* Undescribed South-American species exist in collections.
