228 PHYTOPHAGA.—SUPPLEMENT. 
1. Hermesia aurata. 
Colaspis awrata, Oliv. Ent. vi. p. 882, t. 1. fig. 8 , 
Hermesia aurata, Lefévre, Bull. Soc. Ent. Fr. 1877, p. clxxviii *. 
Var. Rhabdophorus violaceus, Jac. huj. op. p. 151°. 
Hab. Nicaracua, Chontales (Janson*); Panama, Volcan de Chiriqui, Bugaba 
(Champion).—Gvutana, Cayenne+?; Amazons (coll. Jacoby). 
Panama specimens are either of a metallic green or dark blue colour; they have the 
thorax rather more transversely-shaped than in the type. The dark blue variety, which 
agrees entirely with the green specimens in every way except in colour, has been 
described by myself as a distinct species under the name of Rhabdophorus violaceus °. 
CORYSTHEA (p. 153). 
If Lefévre’s opinion of the true affinity of the single species included by me in this 
genus proves to be correct, Corysthea must be erased from our list. 
CHALCOPHANA (p. 154). 
Chalcophana cincta (p. 155). 
To the localities given, add:—Mexico, Cerro de Plumas, Matamoros Izucar (Hége), 
Fortin and Atoyac in Vera Cruz (H. H. Smith). 
The fulvous elytral band is only just indicated at the sides (and entirely obsolete on 
the disc) in some specimens; it is very variable in width. I have also examples before 
me with only the four (instead of the six) basal joints of the antenne fulvous. 
Chalcophana championi (p. 155). 
To the localities given, add :—Muxtico, Soledad, Xautipa, Chilpancingo, Amula, all 
in Guerrero (H. H. Smith); Brrrish Honpuras, R. Sarstoon (Blancaneauz). 
The Mexican specimens lately received have the first four joints of the antenne 
fulvous and the elytral band prolonged laterally to the margins; in other respects they 
agree with the type. They have the thorax narrower than in C. cincta, and much 
more strongly and more closely punctured, and the elytral punctuation coarse and irre- 
gularly placed in single rows, the interstices being more or less convex ; this is also the 
case with the Guatemalan examples, which, however, have only two or three joints of 
the antenne fulvous and the elytral band abbreviated at the sides. 
Chalcophana ancora (p. 156). 
The Guatemalan specimens referred to C. ancora prove on renewed examination to 
belong to a closely allied but distinct species, which I describe below under the
