To the locality given, add :—Panama, Taboga Island (Champion). 
White described the female of this species from Guatemala. The single specimen 
taken as above by Mr. Champion is a male, and differs from the female by the elytra 
having each an oblique line and the lateral margins (narrowly) reddish testaceous, instead 
of the entire outer half being of that colour. The species is distinguished in both sexes 
from the very closely allied 7. larroides from the Amazons by the abdomen beneath 
being ringed with bright yellow. This species, when alive and at rest, very closely 
resembles hymenopterous insects of the same locality.

One species only of this very distinct genus has previously been described. It is 
from Colombia. 
1. Amphionthe brevicollis. (Tab. XX. fig. 23.) 
Callichrome cosmice similis; postice vix angustata, viridi-metallica, thorace elytrisque nigro-velutinis, his 
sutura nitide, lineisque utrinque obscurius, viridi-metallicis ; antennis nigris; pedibus nigris, femoribus 
4 anticis totis, 2 posticis dimidio basali, rufis; thorace transversim quadrato, lateribus medio late et obtuse 
tuberculato, dorso inequaliter tuberoso ; elytris, apice late flexuoso-truncatis angulo exteriori producto ; 
corpore subtus tenuiter argenteo-sericeo.

Hab. Mexico (Sal/é). 
A female example in the Sallé collection is labelled “n. g. brevicollis, Chevr.”; a 
male in my collection was received from Deyrolle. It may be distinguished at once 
from Callichroma cosmica by the compressed, scarcely dilated, and densely hirsute hind 
tibie. The typical species, A. doris, has black femora and a broad metallic-green stripe 
on the sides of the elytra.
